ESQL, do the following:
1. Close both MaterialSynchronization_MsgFlow.esql and
MaterialSynchronization_MsgFlow.msgflow.
2. Open MaterialSynchronization_MsgFlow.msgflow, and then right-click on the
Compute node and click Open ESQL.
Save MaterialSynchronization_MsgFlow.esql (Ctrl-S) and then click on the
MaterialSynchronization_MsgFlow.msgflow tab to return to the Message
Flow editor. The error on the Compute node is no longer displayed and no items
relating to this task appear in the Tasks view.
Click on the MaterialSynchronization_MsgFlow.esql tab to display
MaterialSynchronization_MsgFlow.esql in the ESQL editor again.
The MaterialSynchronization_MsgFlow_Compute ESQL
module
In the MaterialSynchronization_MsgFlow.esql file, there is a single module of
ESQL called MaterialSynchronization_MsgFlow_Compute. This is the ESQL
module that is referenced from the Compute node Properties dialog box. If
another Compute node, or a Database node, is added to the
MaterialSynchronization_MsgFlow message flow, a new ESQL module is also
created in MaterialSynchronization_MsgFlow.esql for the new node.
The ESQL for the MaterialSynchronization_MsgFlow_Compute module is as
follows:
CREATE COMPUTE MODULE MaterialSynchronization_MsgFlow_Compute

Figure 10-20 Mapping of a DominoDocument to a Customer business object
As has been shown in Figure 10-14 on page 569, the overall business object
DominoDocument contains an array of DominoItem business objects. Each
DominoItem business object represents a field within a Contact document of the
Domino database Customer Contacts. The attribute Name of the DominoItem
business object contains the name of the field it is representing. Each
DominoItem contains a child business object DominoItemValue that holds the
field value within its attribute value.
Based on these structures, the algorithm for performing the
DominoDocument_Customer mapping must traverse the DominoDocument
business object and check whether a DominoItem describes an attribute in the
Customer business object. The details of this algorithm are specified in
pseudo-code in Example 10-1 on page 574.

All rights reserved. xxxi Preface This IBM® Redbook demonstrates the use of WebSphere® Business Integration products to integrate data and processes located in SAP back-end systems. The flexible WebSphere Business Integration Server architecture and the wide range of available application and technology adapters offers the customer a very fast implementation cycle by protecting already made investments. After a review of the general challenges that business integration middleware has to master, the first part of this redbook describes how these requirements are addressed by the IBM WebSphere Business Integration product suite. The book explains how WebSphere Business Integration supports the IBM On Demand strategy and how it relates to Enterprise Service Architectures from other vendors like SAP NetWeaver. The second part introduces common business integration drivers and develops ordinary Use Cases to demonstrate the capabilities of IBM WebSphere Business Integration servers in general and especially the two actual SAP related IBM WebSphere Business Integration Adapters. The business cases illustrate how important it is to have a flexible middleware that can rapidly create new business processes and connect back-end data within a heterogeneous system landscape. The third part describes four of these Use Cases in more technical detail. A separate environment is created for each Use Case to implement the respective Use Case scenario. The following WebSphere Business Integration adapters are utilized to implement the Use Cases: IBM WebSphere Business Integration Adapter for SAP V5.5.0 IBM WebSphere Business Integration Adapter for SAP Exchange Infrastructure V1.0 IBM WebSphere Business Integration Adapter for JDBC V2.4.0 IBM WebSphere Business Integration Adapter for JText V5.4.0 IBM WebSphere Business Integration Adapter for Lotus® Domino® V1.1.0 The business case scenario is specifically contrived to illustrate all integration approaches the above adapters provide, and at the same time, an attempt is made to avoid any fictitious solutions. The final chapter discusses “lessons learned”, and the appendixes include the source code and scripts used to create the Use Case environments.

It describes the IBM Business Integration Reference Architecture and the SAP NetWeaver technology stack. It also addresses the integration of SAP back-end systems to an IBM WebSphere Business Integration infrastructure. 2
- 52. 10 WebSphere Business Integration for SAP 2.1 Technology overview This paragraph describes the general technology, concepts, styles, models, and terminologies used in common business integration scenarios. 2.1.1 Business Integration needs A typical enterprise consists of a heterogeneous system landscape that is historically grown. It is not uncommon that an enterprise has dozens of technology islands, such as traditional legacy systems, multiple instances of Enterprise Resource Planning (ERP) systems from different vendors, and countless custom-built departmental solutions. Naturally, these systems are implemented by different technologies and execute on disparate operating system platforms. The driver of this heterogeneous development is the business itself. This was the rationale in the past and can be the reason for future IT transformations. At present, there are various business application vendors in the market that provide standard solutions in certain business segments. Every vendor is typically specialized in a specific business area. With the complex and ever-changing business requirements, one-stop-shopping for enterprise applications is usually neither possible nor practical to IT organizations. Currently, there is no ERP solution in the market that is virtually capable of completely covering an enterprise at the requested level of detail. This causes the existence of system landscapes composed of best-of-breed business applications. Enterprises take the opportunity to apply such best-of-breed applications to solve particular business requirements. The fact that any enterprise consists of multiple business areas justifies the rich integration capabilities of appointed business applications that are naturally on demand. Business requirements arise permanently and affect the evolution the fulfillment of a system landscape. Even simple business requirements can lead to fairly complex and challenging requirements for the affected systems. Users, such as vendors, suppliers, business partners, or even employees, generally do not think about system boundaries when they interact with a business. They execute business functions, regardless of how many internal systems the business function cuts across. For example, a customer may call to change his or her mailing address and see whether the last payment was received. In many enterprises, this simple request may span across the customer care and billing systems. Similarly, a customer placing a new order can require the coordination of many systems. The business needs to validate the customer ID, verify the customer’s good standing, check inventory, fulfill the order, get a shipping quote, compute sales tax, send a bill, and so on. This processes may easily span
- 53. Chapter 2. Business Integration technology concepts 11 across multiple different systems. From the customer’s perspective, it is only a fairly simple, single business transaction. These applications must be integrated in order to support common business processes. The business integration solution of choice has to feature special enterprise characteristics in the areas of reliability, scalability, and security to deliver a certain quality of service. 2.1.2 Integration challenges By definition, enterprise integration deals with multiple applications running on diverse platforms which are distributed. Standard business application software vendors offer integration suites that provide cross-platform integration. Additionally, the ability to interface with many other popular, packaged business applications has become more and more important. However, this technical infrastructure presents only a small portion of the integration complexities. The true challenges of integration span far across business and technical issues. Enterprise integration requires a significant shift in IT alignments. Business applications generally focus on a specific functional area, such as Customer Relationship Management (CRM), Billing, Finance, and so on. As a result, many IT groups are organized in alignment with these functional areas. Successful enterprise integration needs to establish integration links between these different business units and IT departments. In an integrated enterprise application landscape, the groups that control specific applications have to provide well defined interfaces and methodologies to participate in the overall meshwork of integrated applications and services. Integration efforts usually have far-reaching implications on the business because of their wide scope. Once the processing of the most critical business functions is incorporated into an integration solution, the proper functioning of that solution becomes vital to the business. A failing or misbehaving integration solution can cost a business a lot of money in lost orders, misrouted payments, and dissatisfied customers. One important constraint of developing integration solutions is the limited amount of control the integration designers typically have over the participating applications. The collaboration between integration designer and application owner is vital for the development of an efficient integration solution. In most situations, the applications are legacy systems or packaged applications that cannot be changed just to be connected to an integration solution. The integration solution has to provide these flexible abstraction layers to bring all participating back ends to a common denominator. Platform independency and system neutral connectivity and communication paradigms support the successful implementation of such a business integration solution.
- 54. 12 WebSphere Business Integration for SAP The usage of common accepted standards is the most promising method of resolution. Despite the widespread need for integration solutions, only a few standards have established themselves in this domain. The advent of eXtensible Markup Language (XML) is a core building block of system integration solutions. XML participating systems use a mutual character set for communication, which is the foundation for further integration efforts. Beyond having a common syntactical basis, the integration solution has to provide a common semantic environment. Systems have to understand each other or, rather, the integration solution must be the mediator between systems. The notion of account can have many different semantics, connotations, constraints, and assumptions in each participating system. Resolving semantic differences between systems proves to be a particularly difficult and time-consuming task because it involves significant business and technical decisions. The past has shown that such a semantic consonance cannot be driven by a single company but must be supported and driven by multiple partners that align to a consortium or a foundation. This produces a guarantee that different interests and needs are balanced out and the resulting standards are pillared and promoted by all participants. RosettaNet is a good example for such a consortium, as it defines a common e-business language, aligning processes between supply-chain partners on a global basis. Beside a common syntax and semantics, business integration solutions have to rely on unified access mechanisms that are common across different systems and platforms. These mechanisms can be categorized by specific characteristics, such as synchronous or asynchronous communication style or message oriented integration. Despite the fact that developing integration solutions is challenging in itself, operating and maintaining these solutions can be even more daunting. The mix of technologies and the distributed nature of integration solutions make deployment, operation, monitoring and change management, complex tasks that require a rich combination of skill sets. In most cases, these skill sets are hard to find within IT organizations or are spread across many different individuals. 2.1.3 Concepts and terminologies Here we discuss concepts and terminologies. Integration styles Although there are significantly different approaches to system integration, they can be generally categorized into the following styles: Application Connectivity Process Integration
- 55. Chapter 2. Business Integration technology concepts 13 User Interactivity The purpose and mechanism of these styles are illustrated in the following table. Table 2-1 Integration styles This book primarily focuses on application connectivity and process integration styles. Integration terminology There are many terms used in the integration area. These terms and features are listed in the following table. Table 2-2 Integration terminology Integration term Purpose Application Connectivity Communication between two or more applications. Share and exchange business information in a consistent manner. Process Integration Automate and improve business processes. Compose new processes by incorporating existing business applications. Coordinate business activities that execute across system boundaries. User Interactivity Involve human interactions into process flows. Deliver relevant business information to respective users. A comprehensive view of systems through a suitable user interface. Integration model Definition File transfer Applications create files of shared data for others to consume, and consume files that others have produced. Shared database Applications store the data to share in a common database. Remote Procedure Call An application exposes a certain functionality and makes it accessible remotely. Other applications invoke these functions with or without parameterization. The action may return a result or not. Message oriented middleware Participating parties connect to a central system, and exchange data via defined messages. Supports setups like hub and spoke, one to many, and publish/subscribe. Distributed computing model Object Request Brokers (ORB) provide a run-time environment for business objects and manage their lifecycle and the access to these objects in a consistent manner.

The IBM WebSphere Business Integration product family provides the following capabilities: Model: Design, simulate, and plan business processes Integrate: Link people, processes, applications, systems, and data Connect: Extend processes to your customers and partners Monitor: Control and track business processes Manage: Review, analyze, and improve processes and performance The WebSphere Business Integration product suite implements a hub and spoke approach, where the hub is the WebSphere Business Integration Server, WebSphere Business Integration Server Foundation, WebSphere Business Integration Event Broker, or WebSphere Business Integration Message Broker. The spokes are the adapters that connect to applications, like SAP, or to technologies, like Java Database Connectivity (JDBC). You can find a list of all available WebSphere Business Integration Adapters at: http://www.ibm.com/software/integration/wbiadapters/ Transactional characteristic Provides an enhanced access mechanism to business entities. The execution of business logic is strictly controlled, including defined compensation procedures in case of failure. The assessor receives detailed feedback on how the transaction proceeded. Integration server The core of a broker based integration scenario. It connects various components together in a bus or star topology. Several manipulations can be applied to the business information, such as routing, transformation, and data enrichment. Adapter A component that acts as mediator between the integration server and a respective integration partner. Adapters ease up connectivity by providing a standardized transition between the broker and the participating system. Adapters can offer a great reuse potential if multiple equal back ends are linked together. Service choreography This term describes the composition of new business processes by incorporating existing business logic. The prerequisite is that the relevant components expose their business functionality in a common service based notation and that they support a mutual invocation methodology.

Business Integration technology concepts 19 2.2 IBM Business Integration Reference Architecture The IBM Business Integration Reference Architecture (BIRA) shows the key areas of integration capability that are required for comprehensive, enterprise wide strategies and solutions. This chapter describes the IBM Business Integration Reference Architecture on different levels: Overview about IBM Business Integration Reference Architecture Comprehensive Services of IBM Business Integration Reference Architecture Roles and Artifacts in the IBM Business Integration Reference Architecture IBM Software Offerings in the IBM Business Integration Reference Architecture It also refers to the Service Oriented Architecture (SOA) and e-business on demand and discusses how these are related to IBM Business Integration. 2.2.1 Overview The IBM Business Integration Reference Architecture is a complete and comprehensive architecture that covers all the integration needs of an enterprise. Its services are well integrated and are delivered in a modular way, allowing integration implementations to start at a small project level. As each additional project is addressed, new integration functions can be easily added, incrementally enhancing the scope of integration across the enterprise. The architecture also supports Service Oriented Architecture strategies and WBI Modeler Model Manage Models and simulates business processes graphically. WebSphere Business Integration Workbench: Test, analyze, simulate, and validate business processes and software models. WebSphere Business Integration Workbench server: A Java 2 Enterprise Edition (J2EE) compliant application that can be deployed on WebSphere Application Server on a variety of platforms. It provides repository management and Web publishing capabilities in a centralized data warehouse. WBI Collaborations Integrate Connect Prebuilt, customizable business-process templates that deliver most of the necessary code for a wide variety of business processes running on the WebSphere Business Integration Server. Reduce risk and save time and money by using pre-built, proven products rather than building custom code. Product Capability Features
- 62. 20 WebSphere Business Integration for SAP solutions, given that the middleware architecture itself is designed using principles of service orientation and function isolation. Figure 2-1 gives an overview of IBM Business Integration Reference Architecture. Figure 2-1 BI Reference Architecture - Overview Development Platform Development tools allow people to efficiently complete specific tasks and create specific output based on their skills, their expertise, and their role within the enterprise. Business Analysts who analyze business process requirements need modeling tools that allow business processes to be charted and simulated. Software Architects need tool perspectives that allow them to model data, functional flows, system interactions, and so on. Integration Specialists require capabilities that allow them to configure specific inter-connections in the integration solution. Programmers need tools that allow them to develop new business logic with little concern for the underlying platform. Yet, while it is important for each person to have a specific set of tool functions based on their role in the enterprise, the tooling environment must provide a framework that promotes joint development, asset management, and deep collaboration among all these people. A common repository and functions common across all the developer perspectives (for example, version control functions or project management functions) are provided in the Business Integration Reference Architecture through a unified development platform. Business Performance Management Services Development Platform Process Services Information Services Interaction Services Enterprise Service Bus Business Application Services Enterprise Applications and Data Partner Services Business Application and Data Services Application and Data Access Services Infrastructure Services
- 63. Chapter 2. Business Integration technology concepts 21 Business Performance Management Software Business performance management tools incorporate monitoring capabilities that aggregate operational and process metrics in order to efficiently manage systems and processes. Managing these systems requires a set of capabilities that span the needs of IT operations professionals and business analysts who manage the business operations of the enterprise. These capabilities are delivered through a set of comprehensive services that collect and present both IT and process-level data, allowing business dashboards, administrative dashboards, and other IT level displays to be used to manage system resources and business processes. Through these displays and services, it is possible for Line Of Business (LOB) and IT personnel to collaborate and determine, for example, what business process paths may not be performing at maximum efficiency, the impact of system problems on specific processes, or the relationship of system performance to business process performance. This collaboration allows IT personnel and assets to be tied more directly to the business success of the enterprise than they traditionally have been. One key feature of the IBM Business Integration Reference Architecture is the linkage between the Development Platform and the Business Performance Management Services. The ability to deliver run-time data and statistics into the development environment allows analyses to be completed that drive iterative process re-engineering through a continuous business process improvement cycle. Interaction Services User Interaction Services provide the capabilities required to deliver IT functions and data to end users, meeting the end-user's specific usage preferences. User interaction is handled by a multi-channel access service. A portal can be accessed through various channels like Web browsers, PDAs, mobile phones, voice and so on. All channels share common characteristics, such as the following: Aggregating geographically distributed structured and unstructured information and services into one place. Information accessed can include syndicated content supplied specifically for the purpose of reuse and integration with other material. Collaborative services (also known as communication services) allow people to chat, locate expertise, share calendars, participate in discussion groups, use white boards, and so on. Content management services provide search, tracking, and data mining capabilities. Self-service (also known as transactional services) enable users to interact with systems directly without going through an intermediary, such as a customer representative or salesperson. This allows users to buy products, schedule meetings, check account balances, enroll for classes, and so on.
- 64. 22 WebSphere Business Integration for SAP Supporting personalization for a group or an individual. One of the more interesting aspects of the interaction service is its ability to be different things to different people. One of the ways it does this is through personalization and customization. Process Services Process Services provide the control services required to manage the flow and interactions of multiple services in ways that implement business processes. A business can change how it operates through modeling, automation, and monitoring of processes across people and heterogeneous systems, both inside and outside the enterprise. The process service allows the integration of a complete process end-to-end. Information Services Diverse forms of business information can be integrated across the enterprise. Integration enables coherent search, access, replication, transformation, and analysis over a unified view of information assets to meet business needs. Information Services provide the capabilities required to federate, replicate, and transform data sources that may be implemented in a variety of ways. Business Application Services The IBM Business Integration Reference Architecture also contains a set of Business Application Services that provide run-time services required for new application components. Business Application Services provide new business logic required to adapt existing business processes to meet changing competitive and customer demands of the enterprise. Design and implementation of new business logic components for integration enables them to be fully re-usable, allowing them to participate in new and updated business processes over time. The Business Application Services include functions important to the traditional programmer for building maintainable, flexible, and re-usable business logic components. Partner Services In many enterprise scenarios, business processes involve interactions with outside partners and suppliers. Integrating the systems of the partners and suppliers with those of the enterprise improves efficiency of the overall value chain. Partner Services provide the document, protocol, and partner management services required for efficient implementation of Business-to-Business processes and interactions. Infrastructure Services Underlying all these capabilities of the IBM Business Integration Reference Architecture is a set of Infrastructure Services that provide security, directory, IT
- 65. Chapter 2. Business Integration technology concepts 23 system management, and virtualization functions. Infrastructure services are underlying and supporting services for the IBM Business Integration Reference Architecture. They include: Security service Directory service IT system management service Virtualization service The security and directory services include functions involving authentication and authorizations required for implementing, for example, single sign-on capabilities across a distributed and heterogeneous system. IT system management and virtualization services include functions that relate to scale and performance, for example, edge services and clustering services, the virtualization capabilities allow efficient use of computing resources based on load patterns, and so on. The ability to leverage grids and grid computing are also included in infrastructure services. While many infrastructure services perform functions tied directly to hardware or system implementations, others provide functions that interact directly with integration services provided in other elements of the architecture through the Enterprise Service Bus (ESB). These interactions typically involve services related to security, directory, and IT operational systems management. Enterprise Service Bus ESB provides a standards-based means of application to application communication like Web Services, message transport, and mediation. Application and Data Access Services Wraps the native Application Programmable Interface (API) of Enterprise Information Systems (EIS) like SAP. Adapters are built to present a common client interface to each EIS in a common development tooling. The usage of prebuilt adapters provides rapid deployment and reduces risk. WebSphere Business Integration Adapters are run-time components integrated with the business integration system. WebSphere Business Integration Adapters span a wide range of applications and technologies. All the adapters are two-faced animals. The first part of the adapter is its application-facing component. This is the part of the adapter that has explicit internal coding and knowledge of how to interact with the application or technology. For example, for a database adapter, the application-facing part has database API calls to access the database. For an SAP adapter, it contains Business Application Programming Interface (BAPI) calls to access the SAP system. The adapter's application specific components are different for each different type of adapter. IBM has implemented the code to be able to access the applications or technologies.
- 66. 24 WebSphere Business Integration for SAP The second part of the adapter is the broker facing component. This has the responsibility for interacting with the broker by forming communication links to send and receive the adapter’s data. This component is identical in all adapters. It has the built-in capability to transform the application-originated or destined data to and from a common data representation for transmission to the broker. The data content that is sent to and from the broker is the IBM Business Object. Business Application and Data Services Business Application and Data Services are applications in the existing IT landscape, for example, legacy systems. Business Applications and Data Services can be integrated with the Enterprise Service Bus using Application and Data Access Services like adapters. 2.2.2 Comprehensive Services For effective business integration, the architecture must support a set of services that can be used to implement integration points where and how they are needed. The services represent concerns that should be separated and elaborated as part of the implementation architecture. Collectively, they form the basis upon which people, processes, and data can be integrated. The Business Integration Reference Architecture provides a comprehensive set of services to enable Business Integration (see Figure 2-2 on page 25). The services fit into a tiered architecture that clearly define the broad set of services required for a complete integration solution. The architecture defines not just the functional services, but the operational ones as well.

Applications and Data Access Services This layer of services provides for the access and operational interface to existing application and data with support for transactional services and connection services for databases, messaging systems, and other data sources. Event Detect: Provides notification services based on the event framework that is supported by the specific application/data source. On-Ramp: Enables application/data integration patterns, including one way inbound, request-reply, and solicit reply patterns to support application and data integration. 2.2.3 Roles and sample artifacts The IBM software development platform provides an integrated and complete set of tools that address the integration problem and address role-based development. Looking at the various roles, a few common requirements are listed below: Regardless of the role, a high degree of collaboration is required across roles. Each role requires specialized tools to accomplish its tasks. By applying a clean separation of concerns through the development process, each developer can deploy their artifacts into the architecture based on their role (see Figure 2-3 on page 29).
- 71. Chapter 2. Business Integration technology concepts 29 Figure 2-3 WBI Reference Architecture - Artifacts Roles A Business Analyst: – Captures business requirements. – Models and analyzes business processes. – The Business Analyst typically produces Requirements Documents, Use Cases, and Business Process Models. An Architect: – Models applications and data. – Models activities. – An Architect produces Object Models, Data Models, Class Diagrams, Sequence Diagrams, and Activity Diagrams.

- 72. 30 WebSphere Business Integration for SAP An Integration Specialist: – Acts as the key specialist across integration technologies. – Configures the integration environment, for example, Messaging infrastructure, and Component configuration, for example, processes, collaborations, and adapters. – Interfaces to other specialists, for example, operations, and RDBMS. – An Integration Specialist produces Message Flows, Process Flows/Collaborations, Connection Configurations, and Adapters. A Developer: – Develops the application from the requirements and models defined by the Business Analyst and Architect. – Many types of developers with specific roles are very common. A development team might have J2EE developers, Business Process Developers, Web Developers, and Portlet developers on their development team. – A Developer produces the application components (in many organizations, developers may be specialized to the development of specific types of artifacts, for example, portlets, stored procedures, J2EE components, adapters, and so on.) A Tester: – Develops test cases for the applications and business processes built by the Architects, Developers, and Integration Specialists. – Tests the application/component to ensure the quality of the application. – A tester produces test cases, runs tests, documents test results, and provides communication for quality control aspects of the software development process. Sample artifacts Different run-time artifacts are produced during the development of applications, services, and business processes. These artifacts deploy into various components of the integration architecture. The following are representative of the types of artifacts created and are not meant to describe each in detail. Business Performance Management Services Dashboards: Business performance monitoring interfaces to support key constituencies and stakeholders.

Application and Data Access Services Adapters: Artifacts providing application access integration, including connection management, transactional support, application-specific metadata, and application specific objects. 2.2.4 IBM software offerings The IBM Business Integration portfolio has the greatest functional breadth of any middleware vendor. This allows IBM to offer a single vendor solution to customers and providing “best-of-breed” components for integration solutions (see Figure 2-4 on page 32).
- 74. 32 WebSphere Business Integration for SAP Figure 2-4 WBI Reference Architecture - Software offerings Development platform The IBM software development solution is the part of the IBM on demand operating environment that address your design and build needs. This part of the on demand operating environment is referred to as the IBM Software Development Platform. This platform is open, extensible (based on the Eclipse framework), and supportive of your strategic technology direction. This solution spans UNIX®, Windows, IBM ^, and real-time operating systems. And it works hand-in-hand with software execution platforms from Microsoft®, Sun, Borland, and other vendors, which gives you the broadest choice of development options. The Eclipse framework provides an industry standards tool framework. IBM contributed software/R&D as initial Eclipse technology and the Eclipse foundation is now supported by a group of Consortium Members. The support for Eclipse is huge; Download requests topped 3.1 million in first year (with over 18 million to date), consisting of over approximately 880 K developers, companies, or organizations from over 125 countries. More importantly, vendors are committing to Eclipse. Over 175 vendors use Eclipse as their standard solution framework, including significant commitments from TogetherSoft, Serena, QNX, and Merant with hundreds of open source or freeware plug-in projects available.

Business Integration technology concepts 33 WebSphere Business Integration Modeler WebSphere Business Integration Modeler helps anyone in the organization, whether it be a business analyst or IT specialist, to capture a business process and clearly define and document the process. Both the current (as-is) and the future (to-be) process can be modeled and compared using the simulation and analysis capabilities of WebSphere Business Integration Modeler. Comparing these processes identifies Return On Investment (ROI) opportunities in the business by changing the process as modeled. WebSphere Studio The WebSphere Studio family provides an open extensible Universal Tooling Platform that enables tool integration between vendors as well as providing an extensive set of best-of-breed integrated tools and utilities for application development. In WebSphere Studio Application Developer (WSAD) Integration Edition Version 5.1, business processes can be defined in a new industrial standard called Business Process Execution Language for Web Services (BPEL4WS). Since the BPEL4WS standard does not cover all the functionality needed for process integration, IBM introduced a functional enhancement to BPEL4WS called BPEL4WS Extensions that makes use of designated enhancement points in the BPEL4WS standard. One area of enhancements is the support for person activities (Staff) that are defined as enhanced invoke activities. Business Performance Management Services Here we discuss Business Performance Management Services. WebSphere Business Integration Monitor The WebSphere Business Integration Monitor solution provides dashboard and alert notification services which interact with the integrated event-based monitoring using messaging services to provide heads-up display for Business Process Management (BPM). WebSphere Business Integration Monitor Version 5.1 provides direct interaction with the Common Event Infrastructure. Business Activity Monitoring enables the tracking of business events across the enterprise, and the value chain. This enables real-time metrics from processes in motion, alerts to provide notification on service levels, and exception conditions. Additionally, the dashboard components are enabled to integrate with additional portlets to provide customized views specific for the role. Lastly, the monitor allows operational capabilities, including stopping, starting, or redirecting processes and can be used in tandem with other IT Monitoring solutions, such as the Tivoli® Monitoring for Business Integration.
- 76. 34 WebSphere Business Integration for SAP Interaction Services Here we discuss Interaction Services. WebSphere Portal Server WebSphere Portal Server provides a best-in-class framework for developing and managing user interaction-based integration solutions. WebSphere Portal Server provides page aggregation, markup transcoding, language translation, multi-device support, and internationalization. Multi-device support and internationalization are the static versions of the Markup Transcoding and Language Translation services, respectively. These provide the facilities to easily support multiple languages and devices when portal resources are constructed. Additionally, although not explicitly called out, pervasive messaging is also provided through the WebSphere MQ Everyplace® and Enterprise Service Bus components technology to provide support for additional devices. WebSphere MQ Everyplace suite also provides functions and capabilities associated with the integration of multiple pervasive devices. Process Services Here we discuss Process Services. WebSphere Business Integration Server WebSphere Business Integration Server provides process services via the WebSphere MQ Workflow and WebSphere Interchange solutions, offering an advanced set of integration solutions in conjunction with accelerator technology, such as pre-built collaborations. The WebSphere Business Integration Server components can also be surfaced via Web Services Description Language (WSDL), allowing customers to use foundation technologies to compose higher-order composite applications. WebSphere Business Integration Server Foundation Provides long-duration activities and People-to-App/Staff Services via a native Business Process Execution Language (BPEL) solution. Additionally, the BPEL Process Choreographer solution provides for externalized business rules via the WebSphere Application Server based Business Rule Beans framework. The engine provides for compensating process services as part of overall process flow choreography.
- 77. Chapter 2. Business Integration technology concepts 35 Information Services Here we discuss Information Services. DB2® Information Integrator The DB2 Information Integrator provides direct support for data federation and replication over heterogeneous sources, both traditional relational sources as well as non-traditional sources, including text and XML data structures. Through standard interfaces, including SQL, XQuery, DB2 II, it provides full read/write access across diverse data and content sources. Partner Services Here we discuss Partner Services. WebSphere Business Integration Connect WebSphere Business Integration Connect Advanced/Enterprise provides document exchange services with a rich set of operational tools to manage the trading community. The solution architecture is built on the embedded version of WebSphere Application Server. Additionally, the product provides integrated event/alert management, which is the largest differentiator of the product offering. These tools enable both reactive problem determination via browser-based integration for both the hub and participants as well as an event-driven solution to automatically detect events and notify parties as needed. Business Application Services Here we discuss Business Application Services. WebSphere Application Server The WebSphere Application Server framework provides the market-leading application server, providing best-in-class support for J2EE, XML, Messaging, and Web Services programming models. It produces the integration of autonomic administration and management, JMX management interface, superior transaction performance, and integrated availability and scalability. Additionally, as mentioned above, the WebSphere Business Integration Server Foundation support for native Business Process Execution Language for Web Services (BPEL4WS) provides an integrated solution for developing service oriented architectures. Enterprise Service Bus The ESB architecture construct for end-to-end integration of distributed software applications and components is enabled through a set of messaging solution components, which are standards based, and enable the development of a network of distributed, standards-compliant and platform-neutral interconnection middleware. The ESB provides the connectivity infrastructure for a Service
- 78. 36 WebSphere Business Integration for SAP Oriented Architecture. This places the ESB in context, as its reason for being is to support an open, standards based, and service oriented architecture. Application and Data Access Here we discuss Application and Data Access. WebSphere Business IntegrationAdapters The WebSphere Business Integration Adapters provide connectivity with one consistent framework-based approach and an application specific component, as illustrated in Figure 2-5. All adapters run on the same common framework, ensuring that they can be reused with different brokers as your integration needs change over time. The common framework also allows greater speed and ease of adapter deployment, requiring less skill to install a broad range of adapters. Figure 2-5 Adapter architecture The Adapter can be logically divided into two sections: The Application Specific Component – Provides bidirectional connectivity directly to application API (for example, SAP JCo) or technology interface. – Handles the requirements of accessing the application; includes basic initialization and setup methods, business object handling, and event notification.

- 79. Chapter 2. Business Integration technology concepts 37 The Adapter Framework – Provides the common run-time infrastructure on which a specific adapter is implemented. – Assures uniformity in administration and behavior across the adapter family. – Provides services, such as bidirectional broker interaction, logging, and quality of service. – Handles the requirements of the Transport layer, such as sends and receives BOs, and converts BOs to XML to transport to broker. – Provides Generic Services: BO definition library, subscription manager, logging, and tracing. Host Access Transformation Services WebSphere Host Access Transformation Services, or HATS, is the newest addition to the WebSphere Host Integration Solution. HATS delivers improved ease of use of existing 3270 and 5250 applications by dynamically transforming the screens into more Web-like HTML pages for the end user. DB2 II Classic Federation DB2 II Classic Federation provides access to mainframe data sources such as IDMS and Adabas. The DB2 II Classic can be used in tandem with the DB2 II solution to provide federated access to mainframe data sources as part of an overall data integration architecture. 2.2.5 Service Oriented Architecture (SOA) A Service Oriented Architecture is an approach for building distributed systems that deliver application functionality as service to either end-user applications or other services. A SOA defines an architecture that leverages open standards to represent software assets as services. IBM Business Integration supports the SOA today (supports service definition, interaction, and orchestration). SOA also provides the capability for achieving greater responsiveness. It permits a company to leverage a componentized approach to application functionality that allows composite applications and business processes to be created dynamically and literally in real time. Solutions based on an Service Oriented Architecture also deliver tremendous benefits: Lower development costs Less pain when integrating assets across heterogeneous environments Greater reuse of IT assets More effective security and manageability
- 80. 38 WebSphere Business Integration for SAP SOA is a distributed software model. The key components of an SOA include: Services Dynamic discovery Messages A service is a callable routine that is made available over a network. It exposes an interface contract, which defines the behavior of the service and the messages it accepts and returns. The term service is often used interchangeably with the term provider, which specifically denotes the entity that provides the service. Interfaces are often published in public registries or directories where they are categorized based on different services offered, just as businesses and their phone numbers are listed in a phone book. Clients (service consumers) can look up a particular service by dynamically querying for services based on various categorization features. This process is referred to as the dynamic discovery of services. Service consumers or clients consume services via messages. Because interface contracts are platform- and language-independent, messages are typically constructed using XML formats that conform to XML schema. 2.2.6 e-business on demand e-business on demand is defined as: An enterprise whose business processes (integrated end-to-end across the company and with key partners, suppliers, and customers) can respond with speed to any customer demand, market opportunity, or external threat1 . The new on demand computing environment is an open standards-based, and heterogeneous world, integrated and freely enabled with autonomic capabilities. WebSphere Business Integration supports the transformation to an on demand business. An on demand business has the following characteristics. IT view Integrated A business process is mapped to application logic and integrated through middleware. All data is shared across dependent applications without redundancy. Open The application logic and interface is based on open standards, like J2EE and XML. Also, the application’s logic and data is self-describing. Logic and data describe what is used and how it is used, like Java Beans does. 1 Source: Sam Palmisano, IBM Chairman and Chief Executive Officer, in October 2002
- 81. Chapter 2. Business Integration technology concepts 39 Virtualized The application has a large degree of redundancy to met its Service Level Agreements. Also, it is able to evolve and execute in the face of disasters or attacks. One way to achieve this is to run the application in a Grid environment. Also, the application is location and time independent to “run once” for all languages and locales. An example would be a SAP R/3 Unicode system. Autonomic The application has self-monitoring and self-healing capabilities. The application has the ability to recover from errors, clean up its data structures if corrupted, and continue running all of the time. Business view Responsive Able to sense changes in the environment and to respond dynamically to unpredictable fluctuations in supply or demand, emerging customer, partner, supplier, and employee needs, or unexpected moves by the competition. Variable Able to adapt cost structures and business processes flexibly, to reduce risk, and to drive business performance at higher levels of productivity, cost control, capital efficiency, and financial predictability. Focused Committed to concentrating on core competencies and differentiating tasks and assets; able to use tightly integrated strategic partners to manage tasks ranging from manufacturing, logistics, and fulfillment to human resources and financial operations. Resilient Prepared for changes and threats like computer viruses, earthquakes, or sudden spikes in demand. A business with these attributes requires technology that can support it, but that is not the computing environment that is operating today. No, today's environment is heterogeneous, widely distributed, vertically isolated, and generally more complex than businesses would like. The same IT that is essential to a business' ability to create strategic advantage is also a major obstacle to becoming the kind of fluid, responsive, dynamic business that has been talked about for years. Beyond just transforming department by department, business processes and applications need to integrate horizontally to link data, legacy systems, and
- 82. 40 WebSphere Business Integration for SAP custom applications, and this integration requires new levels of data integrity and transaction processing. An infrastructure built on Web services, new development tools, and open standards is needed. On-demand integration, applications that had previously integrated vertically with an operating system and stand-alone processor must now integrate horizontally, application to application. Applications are written to the middleware layer, not to the operating system, and decoupled from the underlying infrastructure. 2.3 SAP Enterprise Service Architecture This section gives an overview of the SAP NetWeaver technology platform that was announced by SAP in 2003. SAP NetWeaver is the technical foundation for mySAP Business Suite and SAP xApps. It is a rearrangement and consolidation of basic functional and business specific components to support cross-functional business processes. SAP NetWeaver is built on service oriented architecture paradigms and therefore has a lot in common with IBM’s On Demand business strategy. In SAP’s terminology the business applications packaged in the mySAP Business Suite and composed in SAP xApps are mostly referenced as applications that fit into a Enterprise Service Architecture. As shown in Figure 2-6 on page 41, the SAP NetWeaver technology stack can be divided into six core building blocks: People integration Information integration Process integration Application platform Composite application framework Lifecycle management
- 83. Chapter 2. Business Integration technology concepts 41 Figure 2-6 SAP NetWeaver overview This division supports the delivery of business integration capabilities of different levels. The fact that both WebSphere and .Net are mentioned in the official SAP NetWeaver overview chart emphasizes that NetWeaver is designed to interoperate with these primary market technologies. These interoperation capabilities can be pictured as the usage of well-defined APIs and common standards to offer SAP customers who implement SAP NetWeaver reliable bridges between the technology stacks. SAP has introduced the implementation of a huge variety of industry standards in SAP NetWeaver. The adherence and commitment to these standards are a major criteria for the success of the SAP NetWeaver technology. Figure 2-7 on page 42 lists some important industry standards that are supported in the various SAP NetWeaver building blocks. .NET WebSphere… People Integration CompositeApplicationFramework Process Integration Integration Broker Business Process Management Information Integration Business Intelligence Knowledge Management LifeCycleManagement Portal Collaboration J2EE ABAP Application Platform Multi-Channel Access SAP NetWeaver DB and OS Abstraction Master Data Management
- 84. 42 WebSphere Business Integration for SAP Figure 2-7 SAP NetWeaver standards support 2.3.1 People Integration People Integration within SAP NetWeaver is responsible for providing the user with the requested functionality with the right information. People that are in touch with the business, both internal and external users, get a seamless user experience regardless of how many systems are involved to fulfill the particular user request. SAP Enterprise Portal is the core component of the People Integration area. It delivers services like: Unification of business data Personalized views on business data Role-based access to business relevant information The Collaboration component is a part of the SAP Enterprise Portal package. It enables user to dynamically get in contact. Supported communication channels are: Shared e-mail and calenders
- 85. Chapter 2. Business Integration technology concepts 43 Collaboration rooms Threaded discussions Document stores The Multi-Channel Access module is a layer that is put on top of the People Integration building block as an enabler to reuse existing components like portal and collaboration. SAP Mobile Infrastructure (MI) is the platform that enables multi-channel access to information and processes. It extends the reach of existing user interfaces like SAP Enterprise Portal to devices like mobile and handheld devices via wireless and radio frequency technology. Thus business data and functions can be accessed and executed offline and are replicated and synchronized in a consistent manner. 2.3.2 Information Integration The Information Integration section includes products that are responsible for making structured and unstructured information available in the enterprise in a consistent and accessible manner. For a user or system, the access methods are transparent regardless of where the information is originally stored. SAP Business Intelligence (BI) combines important corporate information from various data sources to enable the enterprise to manage and analyze every single business aspect in a very granular manner. SAP BI is able to visualize key success factors very flexibly using a wide variety of formats, such as interactive Web reports and personalized dashboards. SAP BI provides the tools to use information to make the right decision, set strategy, and measure the results of business tactics. SAP Business Information Warehouse (BW) is a data warehouse that forms the foundation of the SAP Business Intelligence solution. The version, which is shipped with SAP NetWeaver ’04, is SAP BW 3.5. Knowledge Management (KM) in SAP terminology describes the products that are used to turn unstructured information into organizational knowledge. This transformation is done by classifying and structuring the enterprise data in such a way that it can be interpreted and is usable to the enterprise systems and the corporate user communities. KM therefore provides a service based single point of access to SAP’s content management system and third-part repositories. The provided services include: Search capabilities Taxonomy Data classification Content management and publishing
- 86. 44 WebSphere Business Integration for SAP Master Data Management (MDM) is a brand new component in SAP’s business application portfolio. It enables the sharing of harmonized master data formerly trapped in multiple systems and ensures cross-system data consistency. The goal is to have a consolidated master data system that reuses existing IT environments and leverages made investments. MDM is a perfect example of how the various components in the SAP NetWeaver technology stack work together and consume each others services. MDM defines only the core business logic, that is, how master data consolidation and management can be implemented. Data extraction and distribution services are provided by the SAP Exchange Infrastructure, which belongs to the process integration module of SAP NetWeaver. 2.3.3 Process Integration Process Integration enables business processes to spread across system boundaries and execute seamlessly across heterogeneous IT landscapes. The products located in this SAP NetWeaver area would be called traditionally middleware in IBM’s terminology. While in the past SAP focused on creating business applications with defined system interfaces for integration and the integration itself was done by dedicated system integrators, SAP is now offering its own process and system integration suite. The technical core component of the process integration layer is the SAP Exchange Infrastructure (XI) (see Figure 2-8 on page 45). SAP XI is the technical infrastructure for XML-based message exchange between SAP and non-SAP systems. It is already shipped with predefined business process templates from SAP. Additionally, new business scenarios can be created using an integrated toolset. SAP XI’s integration capabilities are the foundation for all future SAP applications, such as the Master Data Management example in 2.3.2, “Information Integration” on page 43. SAP XI supports industry standards like BPEL4WS, but is also open to other open standards via pluggable interfaces, where standard formats can be imported and exported.
- 87. Chapter 2. Business Integration technology concepts 45 Figure 2-8 SAP Exchange Infrastructure The Business Process Management (BPM) block pictured in the SAP NetWeaver overview diagram in Figure 3-6 is a component that spans across various SAP NetWeaver areas and can be understood as a virtual product. BPM is used to bring together the right people with the right systems, giving them the required information at the right time. BPM is a process-centric technology to: Automate business processes within SAP components Enable users to interact with business processes Support the full business process lifecycle from design, automation, execution, monitoring, analysis, and optimization Support the business process lifecycle across system boundaries BPM can be divided into three focus areas, which clears up the virtual character of this component: Ad Hoc Workflow: A component of the SAP Enterprise Portal framework that enables individuals to interact with business processes and create new, ad hoc processes. SAP Business workflow: Embedded within the SAP Web Application Server and automates business processes running within SAP components. Traditional SAP users are empowered through this component to interact with business processes. The component SAP Business workflow is not a new invention of SAP NetWeaver, but was already available in the pure ABAP based SAP Application Server.
- 88. 46 WebSphere Business Integration for SAP Cross-Component BPM: Part of the SAP Exchange Infrastructure. It drives complex business processes across business applications and enterprise borders. This component enables business process to execute in heterogeneous system landscapes exceeding SAP applications. As mentioned above, SAP is new in the integration and middleware market. To achieve a fast start in this business area and to speed up the development and release of reliable and accepted products, SAP decided to involve business partners. In October 2003, SAP and IDS Scheer introduced a strategic co-development to integrate IDS Scheer’s ARIS Process Platform with SAP NetWeaver. The goal is to create a comprehensive BPM solution aligning technology with business processes. The product supports the entire process lifecycle leading to an extended BPM solution allowing the customer to optimize business processes from modeling to monitoring: design, model, configure, execute, and monitor. ARIS for SAP NetWeaver, available as product from SAP or IDS Scheer by mid-2004, marks the first milestone on the way to an extended BPM solution and is the crucial point of the BPM building block in the SAP NetWeaver overview (see Figure 2-6 on page 41). 2.3.4 Application platform The application platform of SAP NetWeaver is the SAP Web Application Server (Web AS). It provides the complete infrastructure to develop, deploy, and run all SAP NetWeaver applications. The major key capability of SAP Web AS is the full support for both the proven ABAP and the innovative open source J2EE technology. SAP Web AS integrates the ABAP and Java personalities in one application server. This is not done by providing one hybrid interpreter or virtual machine, but by coupling the ABAP and the Java interpreter via well-defined interfaces and communication channels. Figure 2-9 on page 48 shows that the architecture of SAP Web Application Server can be separated into five areas: Presentation layer: In the presentation layer, the user interface can be developed with Java Server Pages (JSP), Business Server Pages (BSP), or with Web Dynpro technology. The underlying business layer provides the business content in Java or ABAP. Business layer: The business layer consists of a full-featured, J2EE-certified run-time environment that processes the requests passed from the ICM and dynamically generates the responses. The business logic can be written either in ABAP or in Java based on the J2EE standard. Developers can implement business logic and persistence with Enterprise JavaBeans (EJB) using the full J2EE environment. Developers can also access the business objects of applications running in the ABAP environment to benefit from their business logic and persistence.
- 89. Chapter 2. Business Integration technology concepts 47 Integration layer: The integration engine is an integral part of SAP Web AS and allows instant connection to SAP XI. The integration engine provides messaging services that exchange messages between the components that are connected in SAP XI. Connectivity layer: The Internet Communication Manager (ICM) dispatches user-interface requests to the presentation layer and provides a single framework for connectivity using a variety of communication protocols. Currently, modules are available for Hypertext Transfer Protocol (HTTP), HTTPS (extension of HTTP running under the Secure Socket Layer (SSL)), Simple Mail Transport Protocol (SMTP), Simple Object Access Protocol (SOAP), and Fast Common Gateway Interface (FastCGI). Persistence layer: The persistence layer supports database independence and scalable transaction handling. Business logic can be developed completely independent of the underlying database and operating system. Database independence is also made possible by support for open standards. The database interface ensures optimized data access from within the ABAP environment through Open SQL. SAP propagates the outstanding capabilities of Open SQL for ABAP to Open SQL for Java and offers a variety of standard Application Programming Interfaces (APIs) to application programmers, such as SQLJ. Other technologies, such as Java Data Objects (JDO) and container-managed persistence (CMP) for EJB, or the direct use of the Java Database Connectivity (JDBC) API, are also supported.
- 90. 48 WebSphere Business Integration for SAP Figure 2-9 SAP Web Application Server architecture 2.3.5 Solution Lifecycle Management This building block addresses special requirements for heterogeneous enterprise system landscapes. To ensure the cost-effective operation of such complex environments with the requested quality of service in terms of reliability, availability, and scalability (just to mention a few of them), the complete lifecycle of business applications has to be supported. SAP NetWeaver provides centralized technology for all stages of the software lifecycle: Design of IT landscapes Technical installation Development, testing, and deployment of business applications Operation Change management SAP Web Application Server 3rd Party Apps/ Exchange 3rd Party Apps/ Exchange Browser/ Portal Browser/ Portal Connectivity Internet Communication Manager Presentation Layer Web Dynpro Business Layer J2EE/ABAP Persistence Database Interface Integration Layer Integration Engine Integration Engine
- 91. Chapter 2. Business Integration technology concepts 49 SAP NetWeaver provides tools, methodologies, technical and business documentation, and implementation services. 2.3.6 Composite Application Framework SAP Composite Application Framework (CAF) includes the methodology, tools, and run-time environment to develop and run composite applications, called SAP xApps. SAP CAF leverages the service based architecture to rapidly compose new business applications out of reusable patterns. The application design process is model-driven, in order to build applications with as little programming as possible. That means reduced development and deployment time for new applications and business-pattern-oriented integration. A special object access layer decouples underlying systems from business objects and processes. It provides a consistent object model and a rich user experience, and gives developers a productive way to create composite applications on top of a set of heterogeneous applications. SAP CAF includes the methodology, tools, and run-time environment to develop and run composite applications. 2.4 Interoperability of WBI and SAP XI In January 2003, SAP introduced SAP NetWeaver as the new middleware environment for their open standards based, services oriented application software strategy (Enterprise Services Architecture). For future SAP releases, NetWeaver is the standard platform superseding the known mySAP.com technology. One core building block of the NetWeaver technology stack is SAP Exchange Infrastructure (XI). SAP XI is SAP's component for business process management and process integration and shipped within the mySAP Business Suite. Many future SAP solutions like Master Data Management requires SAP XI. Therefore, SAP XI has to be seen as a given in all future SAP environments. Most customers have both integration landscapes in place: SAP XI as an effective solution for integrating within SAP environments and WebSphere Business Integration as the traditional, flexible, and proven integration infrastructure leveraging the huge set of existing technology and application adapters. The fact that most customers are likely to have both WebSphere Business Integration and SAP XI in place makes the interoperability of both integration infrastructures a major success factor. WebSphere Business Integration addresses this demand for interoperability by providing a dedicated WebSphere Business Integration adapter that enables WebSphere Business Integration brokers to communicate with an SAP XI broker. The WebSphere Business
- 92. 50 WebSphere Business Integration for SAP Integration Adapter for SAP XI 1.0 uses common standards like Java Messaging Service (JMS) and SOAP to provide an out of the box integration of this two integration landscape on the message level, as shown in Figure 2-10. Figure 2-10 WebSphere Business Integration and SAP Exchange Infrastructure In addition to the WebSphere Business Integration adapter for SAP XI, IBM and SAP are committed to evolve and implement further standards that ease up business integration activities and make integration across vendor boundaries a feasible task. The Java Connector Architecture (JCA) and the Business Process Execution Language for Web Services (BPEL4WS) are perfect examples for such standards that are driven and supported by both companies.

- 95. © Copyright IBM Corp. 2004. All rights reserved. 53 Chapter 3. Business case scenario This chapter is intended to present a sample of a real-world business scenario, to illustrate what challenges two companies face when they decide to merge with each other. Several business Use Cases are defined for demonstration purposes. Constraints and assumptions are also included for IT implementation. 3
- 96. 54 WebSphere Business Integration for SAP 3.1 Business domain This section describes the current state of two companies that decided to merge and some key requirements that need to be taken into account to ensure a seamless integration of two heterogeneous environments. Due to time and resource constraints, the scenario is intentionally simplified and does not claim completeness or overall soundness. 3.1.1 Current business model of Company A Company A is a retailer in the high-tech industry with subsidiaries around the world. The company manufactures a small set of electronic products in their own factory, whereas the majority of their product portfolio is supplied from a handful of selected partners. To automate the business activities and optimized management, a sophisticated Sales & Distribution process has been developed through years of evaluations. The overall infrastructure for this process comprises a set of best-of-breed business applications and systems that are optimized to guarantee on-time delivery of purchase orders and flexible product information management, which is one of the key factors for the business success and growth. As illustrated in Figure 3-1 on page 55, the infrastructure can be divided into four key parts: eCommerce Portal System Sales & Distribution System Supply Chain System Unconsolidated business applications
- 97. Chapter 3. Business case scenario 55 Figure 3-1 Conceptual model of Company A The eCommerce Portal System serves as the primary sales channel for the company. Customers can access the portal via the Internet using a variety of devices like standard Web browsers, handheld devices, or mobiles. They can browse the product catalog, search for product information, and place orders. Each customer is served with a personalized view of the eCommerce portal, which is adjusted to their special needs and which can be influenced by themselves. Enhanced usability features ease up the daily tasks and made the eCommerce portal an accepted and well-rated business component. Beyond customers, the eCommerce portal is also used by the companies sales agents, who use the traditional sales channel to take phone calls from the clients and enter the order data into the system. Business transactions receive the same quality of service regardless of which user group - customer or sales agent - initiated them. The same business rules and processes are applied to guarantee consistency across the whole enterprise. The Sales & Distribution system is an off-the-shelf product, which handles the order management, tracking, and product distribution. Although the system is based on a standard software product, we were able to customize it to fit Company A’s special business requirements. The system also interacts with various external systems for product information organization and customer data Business Application Business Application Intellectual Capital Corporate Information Sales TeamCustomer Suppliers eCommerce Portal Sales & Distribution Supply Chain System Customer Repository Product Master Data HR Team Procurement Team Regular Employee
- 98. 56 WebSphere Business Integration for SAP management as well as supply chain control. This interaction is based on well-defined and proven interfaces. Most of them are based on open industry standards, which makes regular operation and maintenance an easy task. The Supply Chain system and the Sales & Distribution system are not manufactured from the same business application vendor. The Supply Chain system is an highly customizable ERP product, which automates the supply chain workflow and supplier relationship management. While the eCommerce portal is responsible for providing the customer a first class procurement experience, the Supply Chain system guarantees the corresponding execution, fulfillment and delivery of the customer requests. This sophisticated supply chain process enables Company A to handle their suppliers in a uniform way and gaining additional flexibility to adjust their product palette to react in a reasonable time to changing market situations. The system defines a detailed procedure that new suppliers have to fulfill to be qualified to participate in this supply chain network. The overall infrastructure has been built based on open standards, and specially tailored for the particular needs of Company A with great flexibility, reliability, and scalability. The systems are highly available, and information updates are in real time. However, other than this leading-edge Sales & Distribution process, no enterprise-wide technology solutions have been implemented in the past. There is no common user registry or e-mail infrastructure in place. Each department hosts its own systems and customer data repository that are needed to run its business. The uncentralized process model resulted in a number of stovepiped applications and heterogeneous environments. Business information and intellectual capital is distributed across different locations in the company on disparate platforms. Business requirements that arise that cannot be covered by the three well-aligned business applications listed above take a lot of time and money to be fulfilled. 3.1.2 Current business model of Company B Company B is a niche player in the high-tech industry. The company manufactures high quality digital imaging devices in the upper price segment. Company B does not maintain its own manufacturing line, as all parts and components are purchased from various partners and assembled in an installation plant. The mounted goods are distributed worldwide mostly via wholesalers. The heart of Company B’s IT infrastructure is a common groupware infrastructure, which hosts nearly all internal business application in a uniform way.
- 99. Chapter 3. Business case scenario 57 As illustrated in Figure 3-2, the infrastructure can be divided into three key parts: Sales & Distribution system Assembly plant Groupware infrastructure Figure 3-2 Conceptual model of Company B The Sales & Distribution system is based on a standard business application. Company B invested a lot of time and money to enhance and modify the standard application by custom development to fulfill special business requirements. The reason for this investment was that at this point in time and to date no standard software vendor provides an out-of-the-box solution that covers all requirements. The system supported the internal sales team in processing sales orders received from the wholesalers in a consistent and contemporary way. Additional sales channels are not established. The Sales & Distribution system features open interfaces that incorporate external data sources and provide Sales & Distribution functionality to external applications. An example is Inventory System Product Master Customer Data Sales & Distribution Assembly Plant Suppliers Groupware Infrastructure HR Team Regular Employee Procurement Team Finance HR Corporate Information Business Applications Procurement Sales Team Customer Wholesale
- 100. 58 WebSphere Business Integration for SAP the externalized inventor system, which is tightly connected with the Sales & Distribution system, but is still an autonomous business application. The next virtual component that acts in concert with the Sales & Distribution system is the Assembly plant. The Assembly plant consists of a couple of best-of-breed applications that are interconnected and act as a logical entity to the surrounding environment. The Assembly plant application landscape is historically grown and is tailored to fit specific supplier and production requirements. Each supplier is connected in a proprietary manner. Neither exchanged data formats nor access mechanisms follow an open industry standard concept, but are implemented appropriately. Company B has no common blueprint describing the relationship to a supplier but negotiated different contracts with every partner individually. Company B has a corporate groupware strategy in place. The workplaces of all employees are located within the corporate intranet. The groupware infrastructure drives a huge set of people-centric business applications that the employees have to interact with in their daily job. Common services like electronic mail, Web publishing, and collaboration rooms belong to the groupware landscape. Corporate information databases as well as collaboration capabilities help to increase the efficiency of frequent tasks. Various departments like Procurement, Human Resources (HR), or Financing (FI) run their specific business applications on this groupware infrastructure. Dedicated departments that ensures that these applications follow certain internal standards with regard to: Usability Operation Maintainability The company has an IT department to maintain and enhance all business relevant applications. This group is responsible for evaluating leading-edge technologies to justify the applicability and feasibility of these technologies to support current business processes. Even though Company B is open-minded to new technologies, the tight IT budget is always the limiting factor. Thus, the focus is set more and more to lower the operation costs of the existing IT environments. This should help free up funds that can be used to drive innovations. 3.1.3 Merger business objectives Both companies expect that they can complement each other and perform more efficiently as one company in the marketplace. The merger of the two companies is driven by various business factors: Benefit from complementary product portfolios
- 101. Chapter 3. Business case scenario 59 Achieve cost reduction by sharing common infrastructures Increase efficiency by consolidating business processes Profit from each other specializations in certain business areas Introduce a more flexible company structure The product offerings of the companies do not overlap, but belong to the same sector. This spares expensive product portfolio adjustments. The companies can offer a new merged product catalogue within a very short time frame. Departments that are present in both companies can be pooled together. The HR and FI departments are perfect candidates for such a consolidation. This consolidation would not only take place on the head count level, but also and especially on the business process level. Processes of the former companies must go through detailed reviews that reveal weaknesses and areas of improvement. Completely new business processes have to be introduced to expedite and support the merger. The new company must become a nimble and competitive enterprise that is able to respond to the changing market conditions in a reasonable time. Beyond all these transformation activities, it must be ensured that the traditional business execution is not disrupted. 3.1.4 Unified business model The new enterprise reviews all internal and external business processes step by step to ensure a unified execution of these processes across former company borders. The final goal is to create a single virtual company. The unified conceptual model for the merged enterprise is illustrated in Figure 3-3 on page 60 (please refer to the online version, found at ftp://www.redbooks.ibm.com/redbooks/SG246354, to see the relevant colors).
- 102. 60 WebSphere Business Integration for SAP Figure 3-3 Conceptual model of the merged enterprise The green blocks illustrate the existing infrastructure of the former Company A and the yellow blocks the existing infrastructure of the former Company B. Blocks with mixed colors represent unified components, which leverage existing assets and add new systems for new processes. The red lines depicts where the four processes in the new model are located and are discussed in more detail further in this chapter: Process 1 couples both Sales & Distribution systems to enable customers or sales agents to place orders for former Company B’s products through the eCommerce portal. Process 2 is a brand-new people-centric process that allows authorized employees to request internal purchase requisitions. This requisition has to pass an approval procedure and finally be placed in the electronic procurement system. Sales & Distribution Sales & Distribution Suppliers Common Groupware Infrastructure HR Team Regular Employee Procurement Team Policy Service HR System Corporate Information Business Applications Procurement System Sales Team Customer Wholesale Customer Supply Chain System Sales & Distribution Customer Repository Assembly Plant Inventory System Customer Repository Internal Purchase Requisition System Procurement Team Regular Employee
- 103. Chapter 3. Business case scenario 61 Process 3 connects the inventory validation logic of former Company B products transparently to the eCommerce portal. No adjustments on the portal are required. Process 4 creates a new process to furnish the sales agents. This means adding new customer data through a groupware interface, and storing the new records in a consolidated repository. The details of these new processes are discussed in the sections that follow. 3.1.5 Unified business model benefits The most significant benefit is to sell the former Company B products through Company A’s eCommerce portal. This extends the reach of Company B’s sales market considerably. The open architecture of the eCommerce portal supports this extension perfectly. The eCommerce portal offers a product publication process that all former Company B products have to follow. For the customer, it is a seamless integration. Availability dates and delivery times are provided consistently across all products. The requirement for the underlying business integration middleware is to merge the information from different existing system resources. Another area of synergy is to use Company A’s optimized supply chain to obtain the components required to build the products for former Company B. It is consistent to utilize the existing supply chain when the products are sold in the common eCommerce portal and save costs in the procurement area. All specific supplier relationships are substituted with a unique supplier relations process that ensures on-time delivery of goods and a transparent contract negotiation cycle. The challenging part for the business integration middleware in the short term is to coordinate the exchange of the assembly information of the former Company B products into the existing supply chain network. The new product introduction process must become a unique process for all product categories for mid-term and long-term. These short term and long term requirements must be executable on the same business integration middleware. Company B has a company wide groupware strategy in place. All employees are connected via e-mail and can access company wide information from their workplace. There is a plan to extend this offering to all employees of the merged enterprise. The architecture of the existing groupware infrastructure supports this extension. Together with this initiative, a common employee registration process is introduced. A central user registry is implemented that provides authentication and authorization services to general business applications via standardized interfaces. This central user management concept significantly reduces the administrative overhead. The role based authorization concept ensures that an employee sees and gets the exact information required for its respective job role.
- 104. 62 WebSphere Business Integration for SAP To manage the increased number of employees efficiently in a unique way, it is necessary to develop a set of common Human Resources (HR) processes. These processes must fulfill the requirements of the different job roles in the company and the specifics in the particular countries. The processes have to cover various HR areas like time and travel management, payroll, recruitment, benefits, and personnel development. The HR solution enables the staff department to make management analysis of the actual staff structure. Beyond the administrative usage, the HR solution becomes the central point of access for all applications or processes that require HR specific information. An example could be an internal process that is triggered by an employee and requires the approval of its manager. This application has to query the HR system for this information and request the approval from the respective person. 3.2 Business Use Case definition This section describes four Use Cases in more detail to expose their business workflow processes. The Use Cases are further analyzed from a business perspective only. The technical solution design and implementation using comprehensive business integration technologies is covered in Part 3, “Business scenario solution implementation” on page 143. 3.2.1 Use Case 1 - Product data repository Both companies maintained their own product data repositories, so it is of vital importance to establish a process where product data is maintained in the new enterprise. This new process guarantees that the traditional businesses keep on running while a smooth transition is started to consolidate both repositories. The goal is that the new repository appears to the affiliated business components as one logical component. The product data repository is the new central component of all master data management activities that the company will execute in the future and it has to provide a high level of openness, extensibility, and scalability. The operation of the new product data repository system is done using the existing standard groupware infrastructure so that the induction period for the employees who are maintaining it is as short as possible. Processes for master data creation, updates, and distribution execute in the same environment. A product list is stored in the central repository and distributed to the surrounding business components as required. Changes are done in the central repository and synchronized.
- 105. Chapter 3. Business case scenario 63 The product repository needs to meet the following requirements: Ensure consistency of product data across all business applications. The product data has to be made available in synchronous and asynchronous ways to meet all kinds of demand. Distribute product data to external partners without major architectural changes of the product data repository system. The interfaces of the product data repository have to follow common industry standards. Ensure easy connectivity of various internal applications and external partners. Figure 3-4 on page 64 shows the business case diagram for Use Case 1.
- 106. 64 WebSphere Business Integration for SAP Figure 3-4 Business case diagram - Use Case 1 3.2.2 Use Case 2- Internal purchase requisition process Internal purchase requisitions are a major expense factor of the new enterprise. Having a common internal requisition process in place is essential to achieve cost control and cost savings in the future. The new process enables employees ERP System Data Synchronization and Transformation Enhanced Event Handling Sales & Distribution Material Master Data Legacy System
- 107. Chapter 3. Business case scenario 65 to order goods centrally via an electronic channel. The goods available are predefined to ensure a cost efficient procurement process. The preselection of these goods is done by the procurement department. Depending on the products ordered, different policies are applied accordingly. Some products can be ordered without approval, while others may require specific approval. The order and approval policies are also defined by the procurement department and are located in a separate system. Based on which policies are effective, the new process has to query the enterprise Human Resource (HR) system for employee data to be able to route the approval request to the correct person. The HR system is an independent company wide application that provides employee and organizational data via open service based interfaces. Requests that require approval are presented to the approvers via the same electronic channel using the existing groupware infrastructure. Based on the decision of the approver, orders are placed in the procurement system or rejected. In both cases, the originator of the request is informed about the result. The major characteristic of the internal purchase order requisition process is that it is highly flexible and completely independent from the back-end systems it incorporates to fulfill the specific business process. Changes in the connected systems do not require changes in the business process. The integration of the existing procurement system is done in a way so that it is exchangeable in the future. The goal is to use external procurement system providers in the future to handle the complete delivery process of ordered goods. Figure 3-5 on page 66 shows the business case diagram for Use Case 2.
- 108. 66 WebSphere Business Integration for SAP Figure 3-5 Business case diagram - Use Case 2 3.2.3 Use Case 3 - Inventory availability validation Customers are able to order products from former Company B in the common eCommerce portal. The eCommerce portal calculates availability dates of requested goods online by using a unified available to promise (ATP) check business logic. The customer does not recognize that the shown ATP data is retrieved from a different source. This seamless integration is essential to provide a unified corporate presence to the customer.
- 109. Chapter 3. Business case scenario 67 The ATP check integration is implemented as a non-invasive solution and guarantees that the eCommerce portal business logic on one side and the production system on the other side are not affected. The eCommerce portal is able to relate specific products to the respective ATP check business logic and retrieves the information from the right source. The requested ATP information is real-time data that gives the customer the certainty that the ordered goods are available at the given point in time. An alternative would be to provide static ATP data. This means that a certain lead time is added to the order date. This approach does not fulfill the expected quality of service the eCommerce portal delivers to the customer but can be used as a fall-back solution to be able to provide an ATP date at all. The key characteristics of the desired solution are: Seamless integration into existing eCommerce infrastructure Non-invasive integration style Adjustable to reflect changing market situations in a reasonable time Figure 3-6 on page 68 shows the business case diagram for Use Case 3.
- 110. 68 WebSphere Business Integration for SAP Figure 3-6 Business case diagram - Use Case 3 ERP System Process Automation and Collaboration Sales & Distribution External Availability Check Legacy System
- 111. Chapter 3. Business case scenario 69 3.2.4 Use Case 4 - Customer data repository This Use Case has much in common with 3.2.1, “Use Case 1 - Product data repository” on page 62. Like in the master data area, the new enterprise has to establish a common process for customer base maintenance and introduce a common customer data repository. The goal is to have one logical customer data repository that hosts the customer master data of both former companies. This transformation is done without losing any historical information of the customers. Existing business applications can still access customer data in the same way they used to. The steadily increasing range of business wide applications that rely on the correctness and availability of the customer data necessitates that the customer data repository delivers a high degree of reliability and scalability. Future operation of this common customer data repository can be performed via the existing groupware infrastructure to enhance the usability for the employees maintaining the current customer data repository. The customer master data has to remain consistent even if it is used by various independent business applications. To ensure the high quality of customer data, specific processes are established for customer data creation, change, and deletion. This guarantees the consistency and accuracy of the customer data repository for the future. Different applications require different access methods to the customer data repository. The customer data repository provides synchronous and asynchronous as well as transactional access to the requested data. Its architecture also supports future extensions to exchange customer data with external partners across enterprise boundaries. The major challenge for this solution is to integrate two existing components that are already tightly contained in different landscapes. Integration has to be done by coupling two integration infrastructures together without disrupting their original functionality. The key characteristics of the desired solution are: Single point of maintenance Current and consistent customer data Provide different access mechanisms High availability of this business critical data Figure 3-7 on page 70 shows the business case diagram for Use Case 4.

Solution approaches and technology options This chapter introduces the technology for implementing the Use Cases that are defined in Chapter 3, “Business case scenario” on page 53. The chapter starts by covering general characteristics of the basic technology integration components, namely integration broker and adapters. Then special requirements for SAP integration are collected. Subsequently, an overview of the integration brokers and adapters of the WebSphere Business Integration product family as central technology provider is given. The chapters ends with a discussion of the WebSphere Business Integration adapters for mySAP.com and SAP Exchange Infrastructure. 4
- 116. 74 WebSphere Business Integration for SAP 4.1 Basic technology integration components The understanding of business integration within this book is to connect data and processes of existing Enterprise Information Systems (EIS) into an overall business infrastructure. It is common that EISs used in different business areas run on different platforms and that each EIS provides a typical interface and access mechanism. The heterogeneity ranges from different protocols and data formats at the transport level up to the support of different programing paradigms at the Application Programing Interface (API). One of the main challenges is to agree on a common denominator in terms of finding a universal nomenclature and coordinate the different interface types of the various Enterprise Information Systems that have to be integrated. Given the heterogeneity, using direct interconnections between the different EISs without an intermediate instance would require extending the existing EISs with connection functionality (Figure 4-1). This would result in the development of dedicated connection solutions for converting data and process logic from one EIS to the other. Each of these bilateral connections would be required to extend at least one of the EISs involved. In addition, a huge effort would have to be spent on maintaining and managing connections from many different places. The complete infrastructure would be very static, because changes in one component would require the adjustment of a multitude of affected connections. Figure 4-1 Business Integration with direct connections
- 117. Chapter 4. Solution approaches and technology options 75 A more manageable and efficient architecture for business integration is to introduce a central integration broker and EIS specific adapters (Figure 4-2 on page 75). Figure 4-2 Business Integration with a central integration broker The integration broker is responsible for routing data between participating EISs and performing transformations, such as parsing, mapping, or aggregation, on the received data before forwarding it. In addition, the integration broker may process business logic between connected EISs, for example, synchronization of data from various resources or executing short term or long term business processes. Each EIS is connected to the central integration broker using a dedicated adapter. The adapter is responsible for transforming the EIS specific data into a common format that is agreed upon with the integration broker. The integration broker does all processing and transformation based on the common format. The introduction of a central broker together with specific adapters for the connected EIS constitute the adaptive character of this integration architecture, and prevents complex adjustments when the involved back-end systems change.
- 118. 76 WebSphere Business Integration for SAP An EIS specific adapter contains two outlets (Figure 4-3 on page 76): one interfacing to the respective EIS and one interfacing to the integration broker. The outlet to the EIS understands its given application interface. The outlet to the integration broker supports the interface of the integration broker. In this way, the adapter is an abstraction layer and shields the integration broker from the peculiarities of an EIS. The integration broker must understand only one protocol and one data format when communicating with the adapters . Figure 4-3 Internal structure of an adapter It is common that a fairly complex EIS can be accessed by various interfaces. An adapter is not limited to supporting only one interface per EIS, but it can bundle different interfaces of the same EIS. This can be achieved by configuring the adapter with the description of the exchanged data and the interface type to be used with the EIS (Figure 4-4). This information is stored in configuration files and enables the adapter to cope with EIS specific application data of various data types and access mechanisms during run time. Figure 4-4 Type description driven by data transformation within an adapter Besides doing the transformations, a further main characteristic of an adapter is that it runs within its own process. This relieves the integration broker from accessing the EIS directly, and thus decouples its availability from the other systems to be integrated. Additionally, in this way, the EIS can be accessed without being changed.

- 119. Chapter 4. Solution approaches and technology options 77 Being an active component, the adapter can independently support bidirectional communication between an EIS and the integration broker, as shown in Figure 4-5 on page 77. Figure 4-5 Bidirectional communication between an EIS and integration broker The scenario, in which data get forwarded from an integration broker to an EIS, is called Request Processing, and is usually based on existing interfaces of an EIS, which are called by the adapter directly. The other scenario, called Event Processing, usually drives a business integration scenario in that data, or events, are produced independently within an EIS and need to be forwarded by its adapter to the integration broker. If the EIS cannot be configured to submit events to an external component directly, special functionality must be introduced that enables an adapter to retrieve the event by itself. Normally, this is done using an Event store for buffering events and extending the adapter by a mechanism for detecting events stored there. 4.2 SAP specialities regarding business integration The SAP enterprise server is implemented following a three-tier architecture. The database layer provides the central persistency instance and supports a wide palette of databases of all the major database vendors. The middle tier is comprised of SAP application server instances, which distribute the workload among each other to serve the expected requests within a reasonable response time. The end users are utilizing a specific fat client style SAP graphical user interface (SAPGUI) to access the SAP back-end system.

The traditional SAP business applications were packaged in so called modules written in Advanced Business Application Programming (ABAP) and executed on the SAP Application Server. With the introduction of the mySAP.com technology, this traditional architecture has been extended to support additional standard Internet technologies. Beyond the proven ABAP capabilities, the new SAP Web Application Server (WebAS) comes with an additional Java personality implemented on a full blown Java 2 Enterprise Edition (J2EE) application server. SAP NetWeaver is the current technology platform that delivers business applications on both technology stacks ABAP and Java. Integrating the SAP enterprise server into a business integration scenario has to support the various releases of a SAP enterprise system and its most important interfaces. 4.2.1 Support of various SAP releases SAP provides ambitious business applications in a huge number of business areas. The portfolio goes from standard application modules like Human Resources and Material Management up to industry-specific solutions for the automotive industry or the telecommunication sector. These business applications are not static entities but steadily changing components. The functionality increases and new components for upcoming business areas appear while older releases still have to be maintained and keep on running. It is not unusual that an SAP infrastructure consists of many different SAP releases on different platforms, as shown in Figure 4-6 on page 79.
- 121. Chapter 4. Solution approaches and technology options 79 Figure 4-6 Different SAP system releases The complex SAP infrastructure, with its steadily growing application components, makes specific demands on an effective business integration solution, such as: Support for different software releases and platforms New releases extend the provided business logic and introduce new interfaces. It is common that the various systems run in a heterogeneous infrastructure. With the latest SAP releases, an additional Java technology stack beyond the traditional ABAP stack is included within SAP solutions. This increases the numbers of appointed interfaces significantly. Support for a distributed enterprise architecture The architecture of the business integration solution has to be distributable itself to meet enterprise requirements. The solution must deliver a high degree of adoptability to fit into a multi-staged infrastructure, consisting of multiple SAP environments, like development, test and production, in parallel.

- 122. 80 WebSphere Business Integration for SAP 4.2.2 Support of a staged system landscape SAP business solutions deliver a huge portion of functionality out of the box and SAP applications are highly customizable. This is a major decision criteria for SAP. These custom SAP development efforts are embedded in a proven development architecture. Therefore, SAP introduced a three-stage development concept, as listed below and in Figure 4-7: Development environment Test environment Production environment Figure 4-7 Typical SAP system landscape The first stage contains SAP systems for core development. Multiple developers can work in parallel on the same project without disturbing each other.

- 123. Chapter 4. Solution approaches and technology options 81 sophisticated locking and repository mechanism ensures that the developed assets stay consistent. The focus is to rapidly produce the required application logic. Production features like load balancing, performance, and high availability are out of scope at this stage. At a certain development status, the produced components are transferred to the test environment. At this stage, unit tests are carried out to ensure that the complete application works together as expected. At this point, other applications also have to prove that functional and non- functional requirements are met, such as usability, process flow, error handling, and reasonable response times. Finally, approved application components are transferred to the production environment, which is generally a high available, clustered environment with multiple application servers. This environment must be able to serve the expected workload the custom business application is facing. SAP provides a dedicated transport system to guarantee a consistent replication of newly developed and tested revisions between the different stages. 4.2.3 Support of various SAP R/3 interfaces This section gives the reader an introduction and overview about the different types of SAP R/3 interfaces. It is not common to access raw data within the SAP R/3 system directly. One of the prescribed accessing mechanisms has to be used to accomplish this task: Application Link Enabling (ALE) & Intermediate Documents (IDOC) Remote Function Call (RFC) Business Application Programming Interface (BAPI) Batch Data Communications (BDC) Electronic Data Interface (EDI) Web Services (SAP Web Application Server 6.20 and later) Batch Data Communications, Electronic Data Interface, and Web Services are not within the scope of this chapter. ALE and IDocs ALE can integrate business processes between different back-end systems (SAP and non-SAP). It enables the controlled exchange of consistent business data between loosely-coupled SAP application systems and non-SAP systems. ALE uses IDocs to pass information in and out of SAP. An IDoc is an information container that has an exactly predefined (structured ASCII) format. It can be understood as the serialized representation of a business object. ALE represents an asynchronous communication style.
- 124. 82 WebSphere Business Integration for SAP RFCs RFCs are SAP specific Remote Procedure calls in the distributed SAP landscape. ABAP function modules can be marked as remote enabled and made accessible to a RFC client remotely. The SAP system can act as an RFC server or as an RFC client. RFCs represent a synchronous communication style. BAPIs BAPIs are an object oriented programming interface. A BAPI can be understood as a class or instance method of business object located within a SAP system. Technically, they are implemented as RFC-enabled function modules for an SAP business object’s method. SAP guarantees that the interfaces of the provided standard BAPIs remain stable over a certain release levels. BAPIs represent a synchronous communication 4.3 WebSphere Business Integration product suite capabilities 4.1, “Basic technology integration components” on page 74 introduced the general notion of an integration broker and active adapters. This section shows how these general notions are fulfilled by the WebSphere Business Integration product suite. It first takes a deeper look at the WebSphere Business Integration adapters. Then, three different integration brokers provided by WebSphere Business Integration are introduced. 4.3.1 WebSphere Business Integration adapters At the beginning of this chapter, the common characteristics of an adapter for business integration are introduced. This section covers how IBM WebSphere Business Integration adapters implement these general concepts. The section starts with a discussion of business objects, which describe the common data format handled within WebSphere Business Integration adapters and Integration Broker. Subsequently, the technical architecture of the adapter is described. This section ends with a short presentation of the configuration and development tools. Note: A WebSphere Business Integration adapter consists of the adapter’s connector and its configuration and development toolkits like Object Discovery Agent (ODA). However, for the sake of simplicity, the terms adapter and connector are used synonymously within this book.
- 125. Chapter 4. Solution approaches and technology options 83 Business objects Business objects define a common format for exchanging data between an adapter and an integration broker (Figure 4-3 on page 76). A business object consists of payload data as well as instructions on how to process the data. The payload data is defined as a hierarchical record structure (Figure 4-8). Such a record comprises a list of attributes, either having a simple type, like string, or a reference to a child business object. Arrays are defined as being child business objects of cardinality n. Processing instructions are defined as standard operations, like Create, Update and Delete. The interpretation of these operations, called verbs, within an adapter or integration broker depends on the EIS to be integrated. Figure 4-8 Sketch of a business object Definition “Customer” Technical architecture of WBI adapters A WebSphere Business Integration adapter consists of two parts: the Application Specific Component and the Adapter Connector Framework (Figure 4-9 on page 84). All connectors share the connector framework, but differ in the application specific component. Customer ID type = string Name type = string Account type = Account cardinality=n Profile type = Profile cardinality = 1 Create Update Account ID type = string Credit Data type = string Account ID type = string Credit Data type = string Profile ID type = string Profile Data type = string Profile ID type = string Profile Data type = string AttributesVerbs
- 126. 84 WebSphere Business Integration for SAP Figure 4-9 Adapter architecture The application specific component of an adapter provides bidirectional connectivity with the interfaces of its connected EIS for request as well as event processing. It corresponds to the entities EIS specific outlet and transformations in Figure 4-3 on page 76. The application specific component comprises: A connector base class to initialize and set up the connector. A business object handler for converting EIS specific data into a business object and vice versa. An event notification mechanism to detect and respond to application events within the EIS. Depending on the type of application interfaces, there are two categories of WebSphere Business Integration adapters. Application adapters, like the WebSphere Business Integration adapter for mySAP.com, call the native interface of an EIS. Technology adapters, on the other hand, provide a more generic interface, usually based on open standards, for integrating a connected EIS. An example is the WebSphere Business Integration adapter for SAP Exchange Infrastructure, which is based on JMS. While for an application adapter the transformation between its native data format and business objects can be built in, a technology adapter must be able to handle data from an EIS of various formats, like XML, EDI, or delimited. This can be accomplished by configuring the business object handlers to use a data handler that provides a transformation functionality of a dedicated format.

- 127. Chapter 4. Solution approaches and technology options 85 Corresponding to the entity “Integration broker specific outlet” within Figure 4-3 on page 76, the Adapter Connector Framework provides bidirectional interaction with the integration broker by means of the transport layer. This layer supports WebSphere MQ, JMS, and CORBA IIOP as transport protocols. In addition, the connector framework offers generic services like monitoring, logging, and tracing. Configuration and development tools for WBI adapters The concept of an adapter offers integration of existing EISs using ready-made components and hence without developing dedicated integration solutions. However, this requires an adapter to be a highly configurable entity. Important configuration parameters are: The business object definitions that the adapter is able to handle. The application interfaces, which an EIS offers. Different transport protocols for communicating with an integration server. The integration broker that is utilized. The various tools that are provided for configuring an WebSphere Business Integration adapter are depicted in Figure 4-10. Figure 4-10 Configuration tools for WBI adapters The Connector Configuration tool is used to create and modify the connector’s configuration file that contains all the parameters, which are listed in Figure 4-10.

- 128. 86 WebSphere Business Integration for SAP Business object definitions, represented as XML schemas, are created and edited using the Business Object Designer tool. The definitions are stored within a repository that can be accessed by the business object handler within the application specific component of an adapter. The adapter drives the transformation of EIS. Based on the business object definition, the connector uses the Data Handler to transform EIS specific data into business objects and vice versa, and thus corresponds to the type description entity in Figure 4-3 on page 76. Using the Object Discovery Agent (ODA), a business object definition can be derived automatically from the data formats provided by a EIS. IBM provides a huge portfolio of application and technology adapters. An actual list is provided at the following URL: http://www.ibm.com/software/integration/wbiadapters If a given EIS is not supported by an adapter, it can be developed based on a framework provided by the WebSphere Business Integration Adapter Development Kit (ADK). In the same way, there is an Object Discovery Agent Development Kit (ODK), which consists of a set of APIs to develop a custom ODA. 4.3.2 WebSphere InterChange Server WebSphere InterChange Server (Figure 4-11) is a convenient broker for implementing integration scenarios that involve data and process coordination between different EISs with special requirements on centralized business processing rules. Figure 4-11 WebSphere InterChange Server Architecture At the heart of the InterChange Server are collaborations, which are software modules that contain code and business process logic that drive interactions between connected EIS. The logic of a collaboration comprises static and Enterprise Information System Adapter ASBOASBO ASBOASBOGBOGBO CollaborationCollaborationController GBOGBO WebSphere InterChange Server Business Process Integration Mapping & Cross-Referencing Mapping & Cross-Referencing Mapping & Cross-Referencing Mapping & Cross-Referencing Controller
- 129. Chapter 4. Solution approaches and technology options 87 dynamic routing of data, ranging from simple piping of data between connected EISs to complex synchronization of data from various sources and multi-step process coordination. In order to separate the process logic as much as possible from the connected EIS, the InterChange Server distinguishes between application specific business objects (ASBO) and generic business objects (GBO). An adapter converts EIS specific data into a business object. This is a common format for all adapters; however, from a semantic point of view, it is still dependent on the EIS. For example, an SAP R/3 has its own notion of a data describing “Customer” entities, containing more or different attributes than related business objects from other EIS. Hence, these business objects are named ASBO. A GBO can be regarded as an abstraction of related ASBOs, extracting all the attributes that are relevant for exchange and business process logic. Since collaborations only work on GBOs, they provide - to a certain extent - application independent process logic. A GBO is derived from a ASBO through a data mapping and cross-referencing step. Data mapping is the process of mapping attributes from a ASBO to a GBO and vice versa. It may contain simple transformation steps, like merely copying of attribute data, up to more complex operations, like joining several source attributes to a destination one. Based on a given mapping API, even self developed mapping operations can be used. When attributes in a source and destination business object contain equivalent data that is represented differently, like a customer ID or a country code, the transformation step employs cross-referencing, also called a relationship. A relationship establishes an association between data from two or more business objects and is usually implemented using the contents of database tables. The mapping and cross-referencing step is performed within the connector controller, which is a run-time service that mediates between an adapter and the collaboration on the ICS. Each connected adapter must have a controller as a counterpart within the InterChange Server. Collaborations, mapping, and relationships are created and maintained using dedicated tools, which are controlled from within the Eclipse-based workbench System Manager.
- 130. 88 WebSphere Business Integration for SAP 4.3.3 WebSphere Business Integration Server Foundation WebSphere Business Integration Server Foundation (WBISF) is IBM’s next generation integration platform supporting open industry standards. It is a Java 2 Enterprise Edition (J2EE) compliant application server built on the entrenched WebSphere Application Server. WBISF can be considered as the rebranded name of the WebSphere Application Server Enterprise Edition from Version 5.1 onwards. The rebranding reflects the trend to merge typical integration server capabilities with traditional application server technologies. The goal is to introduce an on demand Integrated Platform Suite that allows you to design, develop, execute, and administer business processes seamlessly across different platforms and system boundaries. The core products that are shown in Figure 4-12 mentioned areas to support the complete business process application life cycle are WebSphere Business Integration Server Foundation V5.1 WebSphere Business Integration Modeler V5.1 WebSphere Business Integration Monitor V5.1 WebSphere Studio Application Developer Integration Edition 5.1 Figure 4-12 On demand Integrated Platform Suite WBISF supports Business Process Execution Language for Web Services (BPEL4WS). This is the de facto industry standard for defining and executing business processes in a flexible and platform neutral manner. The IBM proprietary standard Flow Definition Markup Language (FDML) is still supported, even if it is marked as deprecated, to allow customers to migrate from FDML to BPEL during a transition period. The WebSphere Studio Application Developer Integration Edition (WSADIE) includes wizard driven migration support to minimize transition times as much as possible. In addition, WSADIE provides

Business Process Choreographer (BPC) provides support for business-process applications within the WBISF. WPC supports service composition as specified by BPEL4WS and enables developers to define the structure and behavior of a business process. Typical business processes implemented in an enterprise require the interaction of human and IT resources following well-defined rules. WPC supports long-running as well as short-running business processes. WBISF provides the run-time environment for WPC. WPC is also sometimes called the business process container of WBISF or the Business Process Execution (BPE) container. Figure 4-13 on page 90 shows the components of the container. It is implemented as a J2EE application that uses the underlying WebSphere Application Server run-time services and resources. Important: There are various names for the same characteristics of business processes: Long-running processes – Interruptible processes that can be suspended and resumed. – Process state is persistent. – Also mentioned as macroflow. Short-running processes – Non-interruptible processes that maintain only the active state. – Process state is not persistent. – Also mentioned as microflow.

WebSphere Business Integration Server Foundation, as one integration broker, supports this programing model. The complete WebSphere Business Integration Adapters portfolio can be utilized via the WebSphere Business Integration Adapter Framework. Suitable Mediations are applied on the application specific business objects (ASBO) to generate generic business objects (GBO).

Solution approaches and technology options 91 4.3.4 WebSphere Business Integration Message Broker WebSphere Business Integration brokers provide a publish/subscribe style of messaging. In publish/subscribe messaging, the application that sends the information does not know which application receives the information. The sender application publishes messages that contain the information and applications receive the information according to the topics that they have subscribed to. WebSphere Business Integration Message Broker incorporates and extends WebSphere Business Integration Event Broker. WebSphere Business Integration Message Broker provides point-to-point messaging as well as the Publish/Subscribe style of messaging. In point-to-point messaging, the application that sends the information knows which application receives the information. The benefit of point-to-point messaging is that the broker can route the messages according to the message content. The broker can also manipulate the message content, interact with databases, and even transform the message from one format to another. WebSphere Business Integration brokers products use WebSphere MQ’s messaging and queuing technology to transport information between business applications in the form of messages. WebSphere MQ provides assured, once-only delivery of each message (see Figure 4-15). Figure 4-15 WBI Message Broker extends WBI Event Broker In a WebSphere Business Integration brokers environment, the complete WebSphere Business Integration Adapters portfolio can be utilized via the WebSphere Business Integration Adapter Framework (see Figure 4-16 on page 92). WBI Event Broker WBI Message Broker WebSphere MQ (Incl JMS)
- 134. 92 WebSphere Business Integration for SAP Figure 4-16 WBI Message Broker Architecture The WebSphere Business Integration brokers run time contains message flows, which contain the message routing and transformation logic.The logic of a message flow comprises static and dynamic routing of data, ranging from simple piping of data between connected applications to complex synchronization of data from various sources. An adapter converts application specific data into an application specific business object. The business object is placed as a message in the correct XML-based wire format on a WebSphere MQ queue for the integration broker. The integration broker receives the message and passes it to the message flow. After the message is processed by the message flow, the integration broker places the resulting message on the WebSphere MQ queue for the connector for application B. WebSphere Business Integration Message Broker is used to: Securely connect business applications with those of business partners, suppliers, and customers. Exchange information between applications regardless of the information format, the platforms on which the applications are installed, and the geographical locations and time zones of the applications. Integrate dissimilar computer systems that an organization owns as a result of mergers and acquisitions. Application A Adapter Application BAdapter Message Flow ASBO ASBO WBI Message Broker Note: In contrast to the WebSphere Business Server Foundation and the WebSphere InterChange Server, the WebSphere Business Integration brokers use only application Specific business objects (ASBOs) and not generic business objects (GBOs).

The WebSphere Business Integration Adapter for mySAP.com uses the SAP Java Connector to access SAP R/3 systems. The adapter contains following components: Connector (the run-time component) Connector Configurator tool Business Object Designer tool SAP Object Discovery Agent (SAP ODA)
- 137. Chapter 4. Solution approaches and technology options 95 Figure 4-17 WBI Adapter for mySAP.com architecture, white board style The Connector Configuration tool is used to create and modify the connector’s configuration. It defines which business objects the connector supports and the connector properties. The Business Object Designer tool generates Business Objects, which represent SAP R/3 interfaces, like IDocs, BAPIs, and RFCs. Therefore, it uses the SAP Object Discovery Agent (ODA). The SAP ODA is a very innovative component of the WebSphere Business Integration Adapter for mySAP.com. It connects to the SAP R/3 system and queries it for metadata to get the appropriate interface definitions. This information is used by the Business Object Designer to construct the fairly complex objects which are required at run time. The run-time component of the WebSphere Business Integration Adapter for mySAP.com is the so called connector, which consists of: The connector framework An application specific component Connector Configurator SAP R/3 Application Specific Component Connector Framework SAP ODA WBIMB WICS WAS Business Object Designer XML Schema Connector

Figure 4-18 Modules of the WBI Adapter for mySAP.com - detailed view The connector communicates with the SAP R/3 back end via RFC and it uses the SAP Java Connector (SAP JCo) API. The communication type between the adapter and the integration broker is one of following: WebSphere MQ Java Messaging Service (JMS) Internet Inter-ORB Protocol (IIOP) (Object Request Broker (ORB)) The connector can be deployed on different physical locations, as illustrated in Figure 4-19 on page 97.

Option 2: The connector runs on the integration server. Option 3: The connector runs on a own or third party server. Option 4: The connector runs on a server outside the local area network. BAPI Module The BAPI Module (see Figure 4-20 on page 98) is a Java written subcomponent of the adapter that enables the integration broker to make direct calls to a SAP R/3 application server. The module uses the standard SAP Java Connector (SAP JCo) to establish a connection to the SAP system. As an SAP JCo client application, this invokes the SAP Remote Function Call (RFC) library to connect to the SAP Gateway of the respective application server. The BAPI Module can access any remote enabled function module in the SAP system and represents a non-invasive integration approach; it does not require any modification or adjustments in the accessed SAP back-end system. The business object generation utility, SAP Object Discovery Agent (ODA), generates business object definitions that support BAPIs. The discovery agent interprets the interface of a BAPI, maps its parameters to the business object

Using the SAP ODA in conjunction with the Business Object Designer, it is relative easy to create business objects from complex interface structures.The BAPI Module is unidirectional; it supports calls from the integration broker to the SAP application. Figure 4-20 BAPI Module Hierarchical Dynamic Retrieve Module The Hierarchical Dynamic Retrieve (HDR) Module (Figure 4-21 on page 99) is very similar to the BAPI Module described above. It is also a Java produced subcomponent of the adapter that enables the integration broker to processes hierarchical or flat business objects retrieved from a SAP R/3 application server. The module also uses the standard SAP JCo to establish a connection to the SAP system. The main difference to the BAPI Module is that a dedicated RFC module is used to access SAP metadata of existing SAP tables. The Business Object Designer supports the generation of business objects representing SAP tables using the HDR module. The ODA queries the metadata of the respective database tables and populates the business object automatically. All application specific information is filled in to avoid circumstantial manual actions. The HDR Module supports flat tables as well as nested table constructs. The HDR Module is unidirectional; it supports calls from the integration broker to the SAP application.

- 141. Chapter 4. Solution approaches and technology options 99 Figure 4-21 HDR Module RFC Server Module The RFC Server Module (see Figure 4-22 on page 100) acts as a server to the SAP application. It enables the integration broker to receive business objects from SAP applications that support RFCs. The module uses the standard SAP JCo to implement an RFC Server connection to the SAP system. As with any SAP JCo RFC Server application, this invokes the SAP Remote Function Call (RFC) library to connect to the SAP Gateway of the respective application server. The target SAP system must be configured to accept the RFC Server application on the gateway. This is done by setting up a RFC destination to define the entry point in the SAP Gateway the RFC Server Module is using. Because the RFC Server Module acts as a server to the SAP application, it “pushes” or sends events from the SAP application to the integration broker. This behavior is very different from other modules, which poll the application for events. Like the other modules of the adapter, the RFC Server module can also make use of the Business Object Designer and the SAP ODA to rapidly create new business objects. Several settings during the wizard driven object creation process tell the Business Object Designer that a RFC Server specific business object handler has to be created. The generated Java classes are stored in a different directory than the Java classes created with the other modules. The RFC Server Module is unidirectional; it supports calls from the SAP application to the integration broker.

- 142. 100 WebSphere Business Integration for SAP Figure 4-22 RFC Server Module ALE Module The ALE Module (see Figure 4-23 on page 101) is much more complex than the BAPI Module and the RFC Server Module, because it supports bidirectional communication. The SAP application can call the integration broker and the integration broker can call the SAP application. In addition, the ALE Module implements an asynchronous communication style that adds another level of complexity. The ALE module uses MQ Series queues for Transaction ID (TID) and IDocs management to guarantee a consistent one time delivery of exchanged data objects. The connector checks for subscriptions when processing the data from SAP to the connector. Communications from the broker to the SAP system is often called Request processing, while calls initiated by the SAP system are called Event processing. The SAP RFC libraries are used in both directions and the connection endpoint at the SAP system is the SAP Gateway. Request processing - Integration Broker to SAP 1. The integration broker sends a integration broker business object to the SAP connector. 2. The business object’s data represents a processing request to the connector. 3. The connector converts the business object to a table format compatible with the SAP Intermediate Document (IDoc) format. 4. The connector uses RFCs to the ALE interface of the SAP R/3 system to pass the IDoc data.

- 143. Chapter 4. Solution approaches and technology options 101 Event processing - SAP to Integration Broker 1. The connector receives data representing an application event from SAP in IDoc table format via a RFC Server listener thread. 2. Each event from SAP is considered a transaction and persisted in MQSeries queues. 3. The connector converts the data to a integration broker business object before sending it to the integration broker. 4. The connector updates the status of the processed event. The connector uses a two-step process with a TID to handle each event storing events in WebSphere MQ queues persistently, guaranteeing once-only delivery of data from SAP to the connector. The ALE Module is best used for asynchronous communications. Figure 4-23 ALE Module ABAP Extension Module The ABAP Extension Module (Figure 4-24 on page 104) enables an integration broker to send business objects to and receive events from SAP R/3 applications.

- 144. 102 WebSphere Business Integration for SAP utilizes the standard SAP Java Connector (SAP JCo) to establish a connection to the respective SAP system. The communication is done using a standard RFC connection to the SAP Gateway and executing respective function modules of the ABAP component of the ABAP extension module. The ABAP components consist of various SAP application function modules, database tables, and programs. Some of these ABAP components are developed and delivered as part of the adapter and some are native to every SAP installation. These elements handle the event delivery and business object request processes initiated by the Java component. The ABAP components are delivered in connector transport files to be loaded into an SAP application. The ABAP components are all located in a separate name space and do not override any SAP standard objects. This guarantees that the SAP system, which is using the enhanced functions of this module, are still easy to maintain and to upgrade. CrossWorld Station After the implementation of the transport files, the full functionality of the ABAP Extension module is available. These functions are accessible via SAP transactions and screens. The central entry point to access the base functions of the ABAP components of the ABAP Extension Module is called CrossWorld Station. The CrossWorld Station is a set of R/3 transactions for: Analyzing of adapter logs Monitoring of the adapter Developing inbound and outbound business object definitions Defining event distribution settings Configuring the SAP system to work with the ABAP Extension Module Java components The handle the event delivery and event business object request processes.

Handles business object requests from the Java component by calling the appropriate function modules designed to handle a particular business object type and verb. Detects, triggers, and stores events in the event table. Handles event requests and their subsequent return (event status update) from the Java component. The main feature of the ABAP Extension Module is its advanced event detection mechanisms and business object handlers that manipulate the most common objects from SAP. The ABAP Extension Module can make use of four mechanisms to detect an event in the SAP application: Code enhancements Batch programs SAP Business Workflow Change Pointer Event detection is the process that is used to verify that an event was generated in the SAP application. The event detection mechanism calls an event trigger, which takes the detected event and adds it to an event table in SAP. The objects can be retrieved and manipulated to and from SAP in real time, and they can be also retrieved through both request/reply and publish/subscribe models. The adapter notifies you of the success and status of the object transaction request, and returns the unique ID of any created object. The adapter enables real-time retrieval of complex objects from SAP or requests to create, change, or delete business objects. In contrast to the other modules of the WebSphere Business Integration Adapter for SAP, the ABAP Extension Module is an invasive integration approach.
- 146. 104 WebSphere Business Integration for SAP Figure 4-24 ABAP Extension Module 4.4.2 WBI Adapter for SAP Exchange Infrastructure The adapter that is introduced in this section provides an integration of SAP Exchange Infrastructure into a WebSphere Business Integration scenario. This adapter is available in a version that supports JMS and one that uses Simple Object Access Protocol (SOAP) over Hypertext Transfer Protocol/extension of HTTP running under SSL (HTTP/HTTPS) as the underlying communication technology. The latter has been released recently and thus is only described in this chapter. JMS based WBI adapter for SAP XI The WebSphere Business Integration adapter for SAP Exchange Infrastructure V1.0 allows the WebSphere Integration broker to asynchronously exchange business objects with SAP Exchange Infrastructure using a WebSphere MQ based JMS implementation (Figure 4-25 on page 105). Using JMS supports a transactional message exchange between the two integration brokers and is very well suited for business scenarios where data is changed at the downstream back-end systems.

- 147. Chapter 4. Solution approaches and technology options 105 The WebSphere adapter for SAP Exchange Infrastructure supports requests as well as event processing. The messages sent or received by the adapter are compatible with the IDoc-XML format that is defined by a SAP IDoc structure. Message generation and checking within the adapter is driven by a business object type that is generated by the XML Object Discovery Agent (ODA) from a corresponding SAP IDoc structure. Figure 4-25 Architecture of WBI adapter for SAP XI V1.0 On receiving a business object as a request from the InterChange Server, the adapter calls the XML data handler to convert the business object into an XML message according to a business object type the adapter is associated with. Thereafter, the JMS layer makes the appropriate calls to open a queue session and routes the message into a defined WebSphere MQ queue. Event processing, in which the adapter receives XML messages from SAP Exchange Infrastructure and relays them to the Integration Broker, works similar to the request processing described before. Both kinds of processing are metadata driven, meaning that major format conversions and message routing functions are defined by meta-objects. SOAP based WBI adapter for SAP XI The WebSphere Business Integration adapter for SAP Exchange Infrastructure V2.0 supports Simple Object Access Protocol (SOAP) over HTTP/HTTPS as the underlying communication technology for requests as well as event processing. In this way: SAP Exchange Infrastructure, regardless of its downstream EIS, can be integrated as a web service into a WebSphere Business Integration scenario. or WBI_XI_QueueWBI_XI_Queue XML Message XML Message WBI Integration Broker WBI Integration Broker WBI Adapter for SAP XI XML Data Handler SAP XI SAP XI Business Object Business Object XI_WBI_QueueXI_WBI_Queue XML ODA XML ODA
- 148. 106 WebSphere Business Integration for SAP A WebSphere Business Integration scenario can be exposed as a Web service to the SAP Exchange Infrastructure. Figure 4-26 depicts the architecture of this adapter, using WebSphere InterChange Server as the integration broker. In request processing, a collaboration issues a Web service provided by the SAP Exchange Infrastructure. The collaboration delivers the service call as a top-level business object, containing a request and optional response, as well as fault business objects, to the adapter. Using the SOAP data handler, the business objects are converted into SOAP messages before they are sent to the SOAP adapter of SAP Exchange Infrastructure, usually using a Web infrastructure, such as a Web server, firewall, and Internet in between. On receiving a response to the request, the adapter calls the SOAP data handler to convert the message to a business objects, and returns it to the collaboration. Figure 4-26 Architecture of WBI Adapter for SAP XI, V2.0 In event processing, a collaboration is exposed as a Web service that is called by the SOAP adapter of the SAP Exchange Infrastructure. The steps to be executed in this case are similar to the one described for request processing, except that the direction of processing is changed. For event as well as request processing, both WebSphere InterChange Server and SAP Exchange Infrastructure must agree on an interface description of the Web service in the Web Services Description Language (WSDL) format, which defines the structure of the SOAP messages and, thus, also of the type of the business objects that are exchanged between the collaboration and the adapter. If the interface description is determined by SAP Exchange Infrastructure, the collaboration within the InterChange Server must be developed accordingly. For this scenario, the WebSphere adapter provides the SAP XI Object Discovery Agent (SAP XI ODA) that converts a given WSDL definition into a top-level business object type. Based on this, the collaboration can be developed to send SOAP over HTTP/HHTPS SOAP over HTTP/HHTPS WBI Adapter for SAP XI 2.0 SOAP Data Handler Business Object Business ObjectEnterpriseWebServerEnterpriseWebServer InternetInternet SAP XI SOAP Adapter SAP XI SOAP Adapter SAP XI Server WBI InterChange Server Collaboration WBI InterChange Server CollaborationCollaboration SAP XI ODA SAP XI ODA

For this purpose, the InterChange Server provides the WSDL Configuration wizard, which generates a WSDL file for an existing collaboration.

Solution design This chapter defines a technical solution to the business case scenario described in Chapter 3, “Business case scenario” on page 53, from the standpoint of system architecture, process flow, and data flow, as designed for all four Use Cases. Appropriate integration broker and integration adapter selection is rationalized in the design of each Use Case solution. 5
- 152. 110 WebSphere Business Integration for SAP 5.1 Business process analysis The business process requirements of the merged enterprise are specified in detail in Chapter 3, “Business case scenario” on page 53. Four Use Case definitions were made in that chapter. These areas are discussed here in more detail. Each defined Use Case addresses a particular business problem in different business areas. For this reason, the technical challenges differ from case to case. Table 5-1 categorizes the Use Cases with regard to the integration characteristics and the key technical challenges. Table 5-1 Use Case characteristics Use Case Integration type Purpose Technical challenges Use Case 1 Master data synchronization & Event notification Application connectivity Synchronize the master data of two sales systems. Notify subscribed business components of occurrences, such as a placed sales order. Consistent and reliable product master data synchronization between ERP systems.

- 153. Chapter 5. Solution design 111 5.2 Design principles and methodology Various design principles and methodologies are steadily under discussion on how to do business integration most effectively. One ideal approach is to establish a new technical model for the merged enterprise and to completely replace the heterogeneous environments that consists of mixed technologies in the former companies. However, the compulsory business continuity requirements and financial constraints limit the possibility to rebuild from scratch. Another more practical reason for not taking this approach is the attempt to fuse both environments and obtain a crossbreed that has the strengths of both former business models. Existing assets have to be analyzed and reused as much as possible, and new business processes must be implemented on top of the current infrastructure incorporating existing business functions. The following principles are followed in the technical design: Reuse existing infrastructure where and when possible to avoid cost of additional hardware and software. Satisfy corporate security requirements for secure applications. Apply corporate technical standards, best practices, and guidelines. Force consistency with industry standard architectures to build an open platform that is prepared for future growth. Ensure that a newly-created process function is a collaboration of loosely coupled subsystems. Reuse, not rebuild, business logic. Identify business logic that can be exposed as shared services and make them available as componentized modules. Externalize the common business logic via well-defined interfaces. Minimize the impact to existing client applications. 5.3 System context As discussed in the preceding sections, a tactical solution to efficiently combine both former companies’ infrastructures is to establish a unified technical model by leveraging the existing technical assets in the previously two separate environments.
- 154. 112 WebSphere Business Integration for SAP 5.3.1 Logical model of Company A Figure 5-1 shows the logical architecture of Company A. Figure 5-1 Logical architecture of Company A The eCommerce Portal server is hosted in the Demilitarized Zone (DMZ) and serves customer requests. It is protected by a firewall that filters any external accesses to the system except for standard Web browser based activities. The Sales and Distribution (SD) system that contains the core business logic and confidential corporate data is located in the secure internal networks segment. The external access to this system is only permitted for dedicated system that must be located in the DMZ. In this particular scenario, this is the eCommerce portal server and the Supply Chain System. All other departmental servers reside in the internal trusted network. The internal sales team also uses a Web browser interface to communicate with the Portal Server from the internal trusted network and a rich client application to access the SD system. The SD system stores customer master data in a customer data repository, which is based on a relational database and tightly integrated with the SD system.

Figure 5-2 Logical architecture of Company B In contrast to Company A, Company B has no electronic sales channel. Therefore, all sales orders are handled by the sales team internally. There is no direct interaction between any external network and sales system. Consequently, all servers are allocated inside the internal trusted network. A salesman uses a rich client application to access the Sales & Distribution (SD) system. The SD system is tightly integrated with the Inventory System and the Customer Data Repository.

- 156. 114 WebSphere Business Integration for SAP As described, the Assembly Plant is not one system, but an arrangement of various best-of-breed and custom applications that were historically grown together. Any supplier uses an appropriate rich client application to communicate with various system components of the Assembly Plant and exchange purpose-built business data. A multiplicity of applications are hosted on distributed servers of the internal groupware infrastructure. These applications are self-contained and related to certain business areas. They can be accessed by the groupware clients that are installed on all employee workplaces. 5.3.3 Unified model of merged enterprise The unified model basically combines both infrastructures to form a single virtual environment. Suitable integration technologies are used to link systems together, to expand the existing business workflows and to realize new processes. Due to the fact that the secure environment of former Company A is matured and well-established for external interactions, and the supply chain process is automated, the unified architecture primarily takes this infrastructure as the baseline, with the addition of the former Company B’s assets. The logical architecture of the merged enterprise is shown in Figure 5-3.

Use Case 1a deals with the product data synchronization from the Sales & Distribution System A to B. Use Case 1b is an order event notification from Sales & Distribution System B to A. Use Case 2 is a brand-new process for internal employees to use to leverage the existing groupware application to access a new Internal Purchase Requisition System to submit procurement requests. Use Case 3 handles the product availability validation from the Sales & Distribution System A to the Inventory System. Use Case 4 enables Sales & Distribution System A to retrieve the customer data residing in Customer Data Repository B. New system and integration servers are added to the model, which are described in 5.4, “System architecture” on page 115, to extend the current business processes for the whole family of products from both companies, and handle the new business processes. As the unified environment inherently comprises diverse technologies and platforms, a comprehensive integration solution is needed to meet a broad range of integration demands. Based on the business requirements and technical values of various options discussed in the foregoing chapters, WebSphere Business Integration platform is chosen as the foundation of the integration solutions in all four Use Cases. The detailed rationalization of specific technology selected is provided in each Use Case discussion in the sections that follow. 5.4 System architecture To simplify the environment setup and deployment in this demonstration, system-level requirements, such as load-balancing, failover via redundancy, and scalability are not taken into account in the system architecture. Data center operation, such as monitoring, backup, system management, and zoning are not under consideration. Network and storage requirements are also not considered. All new servers are deployed to the same subnetwork for testing, with limited authentication and authorization. Each Use Case addresses a special business integration demand. The selected integration solution for each Use Case must fulfill different functional and technical requirements. Based on the requirements, a suitable system architecture is put in place. Figure 5-4 on page 116 displays the system architecture.

The available technology options are subsequently evaluated and rationalized to select the best option that fits the particular circumstance. Finally, the solution detail is defined with descriptions of modules and components used. 5.6.1 Process flow Here we discuss the process flow.

The SAP system creates a data record that is stored in the SAP database. 4. The SAP system creates an Intermediate Documents (IDocs) based on the product data and dispatches it to the Integration System. 5. The Integration System transforms the necessary data segments and routes the data chunk to the other SAP system. 6. The recipient SAP system validates the incoming IDoc data. 7. In case the validation fails, an error status code is sent to the Integration System. 8. Otherwise, the IDoc is process in this SAP system and a new product record is created and stored in the database. 9. A success status code is sent back to the Integration System. Use Case 1b The high level business process flow is displayed in Figure 5-7 on page 122.
- 164. 122 WebSphere Business Integration for SAP Figure 5-7 Business process flow for Use Case 1b The step-by-step procedure is explained in the following list: 1. A salesman creates a new sales order of the new products added to the system in Use Case 1a by entering order information via a SAP GUI application. 2. The GUI App sends the data via RFC to the SAP system, which first validates the input data submitted by the user. 3. The SAP system creates a data record that is stored in the SAP database. 4. The SAP system generates a trigger that represents the occurrence of the new order creation. 5. The event is dispatched to the Integration System. 6. Once notified, the Integration System creates a empty data structure and send it back to the SAP System. Start End SAP Database SAP System creates a sales order record. Create System creates an event notification object. Employee enters a sales order. Integration System receives the notification. notify
- 165. Chapter 5. Solution design 123 7. The SAP System populates this data structure with valid values retrieved from the database. 8. The populated data structure is sent to the Integration System. 5.6.2 Technology selection Here we discuss technology selection. Use Case 1a Based on the business process requirements described in the preceding section, there are several technology choices available to implement this workflow. The primary candidate options are: InterChange Server Server Foundation Message Broker All these technologies are useful for asynchronous integration purposes, but there are subtle differences. InterChange Server and Server Foundation fit well into the process integration, whereas the Message Broker is suitable for application connectivity. Furthermore, Message Broker can access the message queues directly in the message-oriented environment. If the message size is fairly large, Message Broker shows superior performance. In addition, Message Broker can dynamically route the message to appropriate receivers, and support a broader range of diverse platforms. In this situation, the primary challenge is the application connectivity and information exchange. The product data structure contains a fairly large chunk of data. These data needs a reliable transport mechanism like message queues. As a result of the technical evaluation, it has been determined that the Message Broker is the best choice in this particular circumstance. Application Link Enabling (ALE) uses Intermediate Documents (IDocs) to pass information in and out of SAP. An IDoc is a container of information in a predefined (structured ASCII) format. IDocs are the preferred file format used by SAP R/3 to exchange data with foreign systems. The key advantages of ALE are standard structure and operation, embedded auditing and troubleshooting functionality in SAP, and broad acceptance as the interface technology for SAP to third parties. Consequently ALE is selected as the adapter to be used in this design.
- 166. 124 WebSphere Business Integration for SAP Use Case 1b Based on the business process requirements described in the preceding section, a few technology options become available to implement this notification. The primary candidate options are: ABAP Extension Module Custom-built code The ABAP Extension Module provides rich functionality within SAP and is therefore considered invasive. It is the only adapter module that supports polling and can be used in conjunction with all other adapter modules to provide this functionality. The Extension Module has advanced event detection mechanisms and business object handlers that manipulate the most common objects from SAP. The objects can be retrieved and manipulated to and from SAP in real time, and they also can be retrieved through both request/reply and publish/subscribe models. The adapter notifies you of the success and status of the object transaction request, and returns the unique ID of any created objects. The adapter enables real-time retrieval of a complex object from SAP or a request to create, change, or delete an object. Even though the custom-build approach works, it takes longer and needs extra effort and skills, so the ABAP Extension Module is the best solution to this problem. 5.6.3 Solution details The solution to these two workflows in this Use Case is illustrated in Figure 5-8 on page 125. The WebSphere Business Integration Message Broker is used as the Integration System. ALE connectors are installed on both SAP systems for Use Case 1a, whereas the ABAP Extension Module is utilized in Use Case 1b. Figure 5-8 on page 125 is used to clarify, in which order, the various steps are triggered in the Use Case. The arabic numbers describe Use Case 1a and the Latin numbers describe Use Case 1b.
- 167. Chapter 5. Solution design 125 Figure 5-8 Solution detail for Use Case 1 Use Case 1a 1. A sales person creates a product in SAP via the SAP GUI. 2. As soon as the product is added in SAP‘s product repository, SAP sends the product data in the form of an IDoc to the connector using ALE. 3. The WebSphere Business Integration system processes the data: a. The connector transforms the IDoc into a business object and sends it to the broker. b.

The process flow is discussed from a technical perspective. The available technology options are subsequently evaluated and rationalized to select the best option that fits this particular circumstance. Finally, the solution detail is defined with descriptions of modules and components used. 5.7.1 Process flow The high level business process flow is illustrated in Figure 5-9 on page 127.

Yes No Human interaction to approve or reject the request via a Web browser. Procurement System Place order to the Procurement System. Messaging System Prepare process feedback.
- 170. 128 WebSphere Business Integration for SAP The step-by-step procedure is described as follows: 1. An employee logs in via a Web browser for authentication and authorization to access the Internal Purchase Requisition System. 2. Once authenticated, the employee enters data for a purchase request and submits the order in the browser. 3. The Internal Purchase Requisition System confirms that the request is received and processed. 4. The Internal Purchase Requisition System retrieves additional employee data from the Human Resource System. 5. The Internal Purchase Requisition System communicates with the Policy Service to retrieve approval policy for the requested goods. 6. If the requested goods do not need any approval, the order is placed to the Procurement System. 7. Otherwise, the request is routed to the respective person for authorization. 8. The authorizer reviews the request details and decide to accept or reject the request. 9. If the request is authorized, the order is placed to the enterprise procurement system. 10.An e-mail notification is subsequently sent to the requester, together with the purchase order number generated if the order was successful; otherwise, the requester is notified about the rejection. 5.7.2 Technology selection The internal order application is a process driven business integration solution that requires asynchronous and synchronous invocation of existing enterprise services. On the process level, all the different business logic providers must be accessed in a general way to enable the process to run regardless of the enterprise service it is utilizing. A persistency layer is required to store the process status and progress. Modifications of the actual business process have to be done fairly simple by just adopting the business flow. There are several products available which offer this functionality and can cover the named functional and technical requirements. WebSphere MQ Workflow supports long-running business process workflows as they interact with systems and people. It is best suited to analyze, monitor, and improve critical business processes that execute in WebSphere MQ prevalent environments. WebSphere Interchange Server is a business integration solution for process integration and enterprise application connectivity. It is capable of coordinating business process activities that span multiple distributed applications.
- 171. Chapter 5. Solution design 129 Collaborations graphically define end-to-end processes.There are a huge number of predefined and proven collaborations already available out of the box that can be reused to speed up implementation. WebSphere Business Integration Server Foundation extends and integrates existing IT assets using a next generation integration platform optimized for building and deploying composite applications. Major features and benefits are: Support for a standard based model and a grammar for describing the behavior of a business process based on interactions between the process and its partners Comprehensive development environment, including drag-and-drop tools to visually define the sequence and flow of business processes Strong support for activities that require human interaction Standard based support for business processes that integrate with back-end systems Builds on the latest J2EE standards based WebSphere Application Server platform Native support of J2EE and Web Service integration technology The following business process requirements make WBISF the best choice to implement this business process: Strong focus on user interaction and integration Incorporation of existing business processes to create a new business process Existing business processes can be exposed using clearly defined interfaces Support of synchronous and asynchronous communication styles Exchanged data is fairly small - event flow instead of payload processing Requirement to have a standards based and future-proof integration platform Persistency of business processes is implemented by using WebSphere MQ as a queueing mechanism. This enables WBISF to use all scalability, reliability, and security features of WebSphereMQ out of the box. The run-time architecture is multi-tiered and consists of following components: Business process container: Run-time environment for standard based business processes Adapter framework: Run-time environment for standards based back-end connectivity adapters Development environment: Eclipse based visual tooling
- 172. 130 WebSphere Business Integration for SAP Communication layer: WebSphere MQ connecting process container and adapter framework The business process container resides on the application server and can make use of all distribution and clustering mechanisms of WebSphere Application Server. The back-end connectors are distributable and scalable across different systems and communicate with the process container using WebSphere MQ. The connector receives message based requests and translates them into the SAP specific RFC protocol, executes the call into the back-end system, and puts the response back to the WebSphere MQ response channel. In addition to the mediate connector approach, business processes can also invoke an enterprise service directly using Web Service technology. This enables business processes running on WebSphere Business Integration Server Foundation to connect to a huge range of business components without extensive effort by using the WebSphere Application Server built in Web Service support. SAP BAPIs are the standard way to invoke business logic, which is located within SAP ERP systems in a synchronous style. SAP guarantees that BAPI interfaces remain unchanged over certain software releases. This makes them a good choice to avoid frequent adjustments in the integrating applications that typically surround an ERP system. 5.7.3 Solution detail This section describes the steps from a component view: 1. An employee uses a standard Web browser to log in to an application and to create an internal purchase order requisition. 2. The application immediately provides an acknowledgment to the employee and starts the process flow. 3. The application uses the employees input to execute a synchronous Web Service call at the policy system to find out if the ordered product requires an approval. The policy service returns a Boolean value. 4. In the next activity, the application places a JMS message into the WebSphere MQ request queue. This queue is observed by the WebSphere Adapter for mySAP.com that connects to the human resource system (SAP). 5. The connector takes the message based request, executes the respective BAPI call in the human resource system, and puts the response back to the queue in a message format. 6. The application picks up the response and stores the employees mail address information for further processing.
- 173. Chapter 5. Solution design 131 7. If no approval is required, the application places a JMS message into the WebSphere MQ request queue. This queue is observed by the WebSphere Adapter for mySAP.com that connects to the procurement system (SAP). 8. The connector takes the message based request, executes the respective BAPI call in the human resource system, and puts the response back in the queue in a message format. 9. The application picks up the response and stores the employee information for further processing. 10.If the product requires an approval, a work item is created and displayed in the approver’s work list.The process is halted until the approver processes the staff activity either by accepting or by rejecting the request. 11.The approver uses a standard Web browser to log in to the application. The application recognizes the approver and displays all open work items. 12.If the approver accepts the order, the application places a JMS message into the WebSphere MQ request queue. This queue is observed by the WebSphere Adapter for mySAP.com that connects to the procurement system (SAP). 13.The connector takes the request, executes the respective BAPI call in the human resource system, and puts the response back in the queue. 14.The application picks up the response and stores the employee information for further processing. 15.If the approver rejects the order, the status field of the order is set to Order rejected. 16.In any case, the final step is that the application takes the collected and stored information and sends an notification. A Web Service call is made to a Notification service. This service takes the mail address of the recipient, the message subject, and the message body as input parameters and sends an e-mail to a predefined SMTP host. 17.The status of the internal order is updated and the originating employee can review the processed order. 5.8 Use Case 3 - Solution overview This section provides a component-level design for Use Case 3. The process flow is discussed from a technical perspective. The available technology options are subsequently evaluated and rationalized to select the best option that fits this particular circumstance. Finally, the solution detail is defined with descriptions of the modules and components used.

Figure 5-10 Business process flow for Use Case 3 The step-by-step procedure is described as follows: 1. An employee wants to know if a plant has part X available and how many of part X is available at the location to fill an order. The employee uses the SAP Start Employee enters search criteria in SAP system. Integration system receives function call using adapter. Integration system retrieves data using adapter. Query Request Employee views result in SAP system. End System calls remote Available to promise logic. Inventory System System receives Available to promise result data. Integration system delivers result via adapter.
- 175. Chapter 5. Solution design 133 GUI application to determine the availability of the item. Via the GUI application, the employee fills in the material availability search mask. 2. SAP generates a search request and routes it to an external inventory availability system via an integration mechanism. 3. The external inventory availability system locates the item and returns the response to SAP via the integration mechanism implemented. 4. The employee then reviews the results of the request from the SAP GUI application without knowledge of all the integration that has occurred behind the scenes. 5.8.2 Technology selection Based on the integration requirements of the business process described in the previous section, there are several technology choices available to implement this integration. The primary candidates to implement this integration are: WebSphere InterChange Server WebSphere Business Integration Server Foundation WebSphere Business Integration Message Broker All of these technologies allow the synchronous processing of the desired integration scenario. WebSphere InterChange Server allows for the integration of disparate systems with relatively little or no knowledge of the inner workings of the two systems and is best suited to smaller IT shops and businesses wanting swift, complete, and transparent integrations. WebSphere Business Integration Server Foundation allows the same level of integration, but also allows the additional flexibility to make a front end for managing this process, and/or to customize the integration greatly. WebSphere Business Integration Message Broker can route messages among queues and re-route as needed based on message contents, work with large messages very quickly, and support a much broader range of platforms. This integration needs to be transparent to the user, does not require the overhead of a customized interface, nor does the integration require a great degree of customization. The solution that lends itself most to this criteria is the WebSphere InterChange Server. The WebSphere InterChange Server allows for swift implementation of this integration, does not require a significant learning curve, nor a great IT investment to implement. Choosing the WebSphere InterChange Server for this integration also allows for the transparent integration
- 176. 134 WebSphere Business Integration for SAP of other standardized systems, such as Peoplesoft Enterprise, Siebel, or other similar systems as the business needs change going forward. 5.8.3 Solution detail Figure 5-11 on page 135 shows a detailed flow of what occurs in this solution using the WebSphere InterChange Server.

SAP generates a search request and routes it to the predefined RFC server destination that has been defined as the target for the search. 3. The mySap.com WebSphere Business Integration Adapter receives the request and transforms it to a business object understood by the WebSphere InterChange Server. 4. The WebSphere InterChange Server then uses a predefined map to transform this business object into a IBM DB2 object expected by the JDBC WebSphere Business Integration Adapter. 5. The JDBC WebSphere Business Integration Adapter takes the IBM DB2 Object result and transforms it into a request to IBM DB2 for the desired availability information. 6. The resulting information is passed back through the adapter, converted from a IBM DB2 object, back into an SAP business object, back through the SAP Adapter, and finally to SAP. 7. The employee then reviews the results of the request from the SAP GUI application without knowledge of all the integration that has occurred behind the scenes. 5.9 Use Case 4 - Solution overview This section provides a component-level design for Use Case 4. A high level view on the process flow is given first. The available technology options for realizing the process flow are evaluated subsequently. Finally, a solution detail is defined with descriptions of modules and components used. 5.9.1 Process flow The process flow of Use Case 4 consists of the following steps (Figure 5-12 on page 137): 1. A client representative enters the contact data for a new customer using a Lotus Notes client. 2. The data entered are stored as a document within a dedicated Lotus Domino database. 3. Using Integration technology, new or changed documents within that Lotus Domino database are detected and transmitted subsequently to an SAP R/3 system that hosts the common customer data repository. Thereby, the Lotus
- 179. Chapter 5. Solution design 137 Domino documents get converted into the SAP defined IDoc structure, before being stored there. Figure 5-12 Business process flow for Use Case 4 Start Employee enters search criteria in SAP system. mySAP.com Adapter transforms request to business object for WICS. Request JDBC Adapter transforms business object to query request for IBM DB2. IBM DB2 Query Request JDBC Adapter transforms IBM DB2 response to business object for WICS.

SAP System WebSphere Interchange Server transforms data. SAP System
- 180. 138 WebSphere Business Integration for SAP 5.9.2 Technology selection As shown in Figure 5-12 on page 137, Use Case 4 is about integration of the two enterprise information systems Lotus Domino and SAP R/3. Technology selection for this Use Case is driven by the following major requirements: The SAP R/3 back-end system, which hosts the customer data repository, should be accessed only by using the SAP Exchange Infrastructure. Integration technology, which sits between the Lotus Domino Server and the SAP system, must be able to transform the native formats of Lotus Notes databases into SAP IDoc structures, and vice versa. In addition, the Integration technology must be able to automatically detect and handle events that are triggered by the creation or update of documents within the Lotus Domino database. SAP Exchange Infrastructure supports XML-based message exchange between SAP and non-SAP systems. However, it does not understand the format of Lotus Domino databases, nor can it detect events originating at a Lotus Domino server. For this purpose, the WebSphere Business Integration adapter for Lotus Domino is very well suited. It understands how to detect new or updated documents within a given Lotus Domino database and supports the bidirectional exchange of these documents between a Lotus Domino Server and a WebSphere Business Integration Server. The adapter for Lotus Domino can be attached to all the different Integration Servers that have been described in the previous sections. Since the focus of this business process is the integration of disparate systems with a moderate amount of data exchange, the WebSphere InterChange Server is selected for the implementation of Use Case 4. The two integration brokers, WebSphere InterChange Server, and SAP Exchange Infrastructure are connected by means of WebSphere MQ queues. Both integration brokers access these queues using their corresponding JMS adapter. Selecting WebSphere MQ as the underlying transport mechanism not only matches the asynchronous nature of the document centric interaction, but also permits you to update the customer data repository with transactional support. Finally, an IDoc adapter is selected to connect the SAP Exchange Server with the SAP R/3 back-end system, which deploys Application Link Enabling (ALE) as the underlying technology.
- 181. Chapter 5. Solution design 139 5.9.3 Solution detail Based on the results of the technology selection, the business process in Figure 5-12 on page 137 is refined, as depicted in Figure 5-13 on page 140.

- 183. Chapter 5. Solution design 141 2. The data entered is stored as a document within a dedicated Lotus Domino database. 3. When an Event Listener process detects new or updated documents within that Lotus Domino database, it puts an event document into a event table. 4. The WebSphere Business Integration adapter for Lotus Domino polls the event table. If a new event is detected, the adapter retrieves the corresponding Domino document to the WebSphere InterChange Server. 5. At the WebSphere InterChange Server, the Domino documents is converted into an XML message that conforms to a given SAP IDoc type. 6. This XML message is written to a WebSphere MQ queue using the JMS based WebSphere Business Integration Adapter for SAP Exchange Infrastructure. 7. The WebSphere MQ queue is polled by the SAP Exchange Infrastructure JMS adapter. The adapter retrieves new XML messages from the queue and delivers them to the SAP Exchange Infrastructure Integration Server. 8. The SAP Exchange Infrastructure Integration Server forwards the XML message to the SAP Exchange Infrastructure IDoc adapter. 9. The IDoc adapter converts the XML message into an IDoc and sends them to SAP R/3 using ALE. The conversion requires no mapping, since WebSphere InterChange Server is responsible for providing messages in an adequate format. 10.Finally, the IDoc is received by the SAP R/3 system where it is delivered to an internal process for storing customer data. 5.10 Related technology used in this book This book only covers a subset of the hole IBM WebSphere Business Integration and SAP technology.

It includes the following tasks: Configure WebSphere MQ to work with the WebSphere Business Integration Adapter for mySAP.com and the WebSphere Business Integration Message Broker. Create a WebSphere Business Integration Message Broker Domain. Configure the ALE Module of the WebSphere Business Integration Adapter for mySAP.com.
- 246. 204 WebSphere Business Integration for SAP Configure the ABAP Extension Module of the WebSphere Business Integration Adapter for mySAP.com. 7.3.1 Configure WebSphere MQ WebSphere Business Integration Adapter for mySAP.com uses MQ queues and standard Java Messaging Service (JMS) software as the communication transport mechanism between the connector framework and the broker. To enable WebSphere Business Integration Message Broker to work with a connector, a queue manager must be configured and also queues for carrying messages between the connector and WebSphere Business Integration Message Broker. Ensure that the connector’s configuration files contain correctly specified queue and queue manager information, which is provided in this chapter. Define the queue manager The connector uses a single queue manager to manage all of its interactions with queues. The standard properties in the connector’s configuration file contain the queue manager information needed by the connector at startup. The connector uses this information to establish a connection to the queue manager to be used for communicating with the WebSphere Business Integration Message Broker. The WebSphere Business Integration system supports several queue managers and queue configurations. The connector can communicate with the queue manager in any of the following modes: Bindings mode: WebSphere Business Integration Message Broker and the connector communicate directly with the queue manager, without using a TCP/IP connection. The queue manager and the connector must be on the same machine and must use the same queue manager. This is the default mode and is described in “Create a queue manager using the WebSphere MQ Explorer” on page 205. Bindings mode with remote queue definitions: If WebSphere Business Integration Message Broker and the connector are installed on separate machines, with each machine running its own queue manager, the connector and WebSphere Business Integration Message Broker can still communicate with their respective queue managers using bindings mode, but remote queue definitions are also needed. Client mode: Communication occurs through a client connection that uses TCP/IP as its underlying transport. If the queue manager and the connector are on the different machines, the connector is limited to using client mode. To learn more about MQSeries messages, see WebSphere MQ Using Java, SC34-6066. To learn more about MQSeries queues, see WebSphere MQ:

Use Case 1: WBIMB using WBI Adapter for mySAP.com 207 Define the queues Use MQ commands or the MQ Explorer to define the following local queues (see Table 7-4 and Table 7-5 on page 208) for each connector. Also, the script mqsetup.tst delivered with the WebSphere Business Integration Adapter Framework can be used for defining queues. For more information about defining queues using the script, see 8.3.1, “Configuration of WebSphere MQ” on page 359. Table 7-4 Connector queues Queue name Usage of the queue AdminInQueue Delivers administrative messages from WebSphere Business Integration Message Broker to the connector framework. AdminOutQueue Delivers administrative messages from the connector framework to WebSphere Business Integration Message Broker. DeliveryQueue Delivers event delivery messages from the connector framework to WebSphere Business Integration Message Broker. FaultQueue Delivers fault messages from the connector framework to WebSphere Business Integration Message Broker. The connector framework places a message on this queue when it is unable to place the message on the reply-to queue. RequestQueue Delivers request messages from WebSphere Business Integration Message Broker to the connector framework.
- 250. 208 WebSphere Business Integration for SAP If the ALE module of the adapter is used, additional local queues must be defined. Table 7-5 Connector queues for the ALE module SynchronousRequestQueue Delivers request messages from the connector framework to WebSphere Business Integration Message Broker that require a synchronous response. This queue is necessary only if the connector uses synchronous execution. With synchronous execution, the connector framework sends the message to SynchronousRequestQueue and waits for a response back from WebSphere Business Integration Message Broker on the SynchronousResponseQueue. The response message sent to the connector bears a correlation ID that matches the ID of the original message. SynchronousResponseQueue Delivers response messages from WebSphere Business Integration Message Broker to the connector framework sent in reply to a synchronous request. This queue is necessary only if the connector uses synchronous execution. Tip: To make it easier to determine the associated queue of each connector, prefix the queue name with name of the connector. For example, name the SAP connector’s event delivery queue SAPCONNECTOR/DELIVERYQUEUE. Queue name Usage of the queue ArchiveQueue Specifies the MQ Series queue that archives TIDs and IDoc data after the ALE Module has finished processing events. EventQueue Specifies the MQ Series queue that stores TIDs and IDoc data during the ALE Module’s processing of events. Queue name Usage of the queue
- 251. Chapter 7. Use Case 1: WBIMB using WBI Adapter for mySAP.com 209 For more information about defining queues, see WebSphere MQ System Administration Guide, SC34-6068 and WebSphere MQ: Script Command (MQSC) Reference, SC34-6055, both of which can be found at: http://www-306.ibm.com/software/integration/mqfamily/library/manualsa/manua ls/crosslatest.html Create local queues using the MQ Explorer 1. Open the MQ Explorer and select the Queues folder in the queue manager. ErrorQueue Defines a queue to handle MQ messages that fail between the WIPQueue and the EventQueue. WIPQueue Specifies the MQ work-in-progress (wip) queue that holds TIDs and IDoc data while the ALE Module builds the MQ message for the event queue. After the connector receives all data for an event, it moves the data in this queue to the EventQueue. UnsubscribeQueue Defines a queue to collect unsubscribed IDoc objects. Unsubscribed IDoc objects previously were placed in the ArchiveQueue. These messages can be resubmitted using the event management utility. The connector now checks for subscriptions when processing the data from SAP to the connector, resulting in transactions remaining in SAP until the message flow is started. TidQueue Specifies the queue on which messages containing the TID and TID status reside. This property is used by the ALE Module only when processing requests. Tip: To make it easier to determine the associated queue of each connector, prefix the queue name with name of the connector. For example, name the SAP connector’s archive queue SAPCONNECTOR/ARCHIVEQUEUE. Tip: The supplied configure_mq.bat file can also be used to set up the queues. Queue name Usage of the queue
- 252. 210 WebSphere Business Integration for SAP 2. Select Action → New → Local Queue. 3. Enter SAPCONNECTOR/DELIVERYQUEUE as the queue name. 4. Repeat steps 2 and 3 for each queue listed above. Define the channels Use MQSeries commands or the MQ Explorer to define server connection channels. The following channels are required by the WebSphere Business Integration System. Create channels using the WebSphere MQ Explorer 1. Open the MQ Explorer and select the Advanced folder in the queue manager. 2. Select the Channels folder. 3. Select from the menu Action → New → Server Connection Channel. 4. Enter CHANNEL1 as the channel name. 5. Repeat steps 2 and 4 for each ALE channel that is required (one per ALE module. In this Use Case, the channels TIDCHANNEL and TIDCHANNEL2 are used). 7.3.2 Create a message broker domain A message broker domain represents the WebSphere Business Integration Message Broker run-time environment. A broker domain contains a single Configuration Manager with associated brokers. It may also contain a User Name Server if authentication is used for publish/subscribe messaging. This Use Case does not use a User Name Server. To quickly create a default configuration for WebSphere Business Integration Message Broker run the Getting Started wizard in the Message Broker’s Toolkit. When you are familiar with WebSphere Business Integration Message Broker, broker domains can be created manually. To learn more about broker domains, refer to the redbook WebSphere Business Integration Message Broker Basics, SG24-7090. Tip: The supplied configure_mq.bat file can also be used to set up the channels

Use Case 1: WBIMB using WBI Adapter for mySAP.com 211 Create a broker using the Getting Started wizard The Getting Started wizard creates the minimum components that are needed to run a message flow application. In order to run the Getting Started wizard, prerequisite software such as DB2 and WebSphere MQ must have been installed. The wizard creates: A broker. A DB2 database for storing the Configuration Manager’s data. A DB2 database for storing data that is deployed to the broker. A link between the domain and the broker. A queue manager that is used by the broker and the Configuration Manager if no queue manager exists. Use the queue manager ITSOA.queue.manager created in “Create a queue manager using the WebSphere MQ Explorer” on page 205. A configuration for the queue manager to use a listener port for communication between the Configuration Manager and the Message Brokers Toolkit. A project within the Message Brokers Toolkit workspace to contain the broker domain connection information. Table 8-3 lists the components that the wizard creates, and their default values. Tip: The broker, the configuration manager, and the nameserver can be created also using following commands: mqsicreatebroker <BROKER> -i <USERID> -a <PASSWORD> -q <QUEUEMANAGER> -n <BROKER_DB> -u <DB_USERID> -p <DB_PASSWORD> -s <QUEUEMANAGER> -j -P <QM_PORT> mqsicreateconfigmgr -i <USERID> -a <PASSWORD> -q <QUEUEMANAGER> -s <QUEUEMANAGER> -n <CONFIGMNG_DB> -u <DB_USERID> -p <DB_PASSWORD> mqsicreateusernameserver -i <USERID> -a <PASSWORD> -q <QUEUEMANAGER>

Use Case 1: WBIMB using WBI Adapter for mySAP.com 243 7.6 Configuration of SAP R/3 to work with the ABAP Extension Module of the Adapter The ABAP Extension Module of the WebSphere Business Integration Adapter for mySAP.com provides rich functionality within SAP R/3. It is the only adapter module that supports polling and can be used in conjunction with all other adapter modules to provide this functionality. The ABAP Extension Module has advanced event detection mechanisms and business object handlers that manipulate the most common objects from SAP. The objects can be retrieved and manipulated to and from SAP in real time, and they also can be retrieved through both request/reply and publish/subscribe models. The adapter notifies you about the success and status of the object transaction request, and returns the unique ID of any created objects. The adapter enables real-time retrieval of a complex object from SAP or a request to create, change, or delete an object. This section contains the following topics: Creating CWLD namespaces Making the namespace CWLD available for modifications Installing connector transport files for the ABAP Extension Module Processing the business objects in the ABAP Extension module Creating an Event triggering and detection mechanism using Business Workflow 7.6.1 Creating the /CWLD/ namespace Before the transport files for the ABAP Extension Module can be installed, a namespace must be created in SAP R/3. Do the following steps: 1. Open the Transport Organizer (transaction se03). 2. Expand the Administration menu and double-click on the Display/Change Namespaces option (see Figure 7-61 on page 244).

- 290. 248 WebSphere Business Integration for SAP After the namespace is created, the WebSphere Business Integration transport files can be installed. 7.6.2 Install connector transport files for the ABAP Extension Module All of the SAP R/3 transports of the WebSphere Business Integration Adapter for mySAP.com for Windows can be found in the connectorsSAPdependenciestransports directory, and for UNIX they are found in the /connector/SAP/bin directory. The transports are installed on an SAP R/3 application server, as described below. The transport files for the IBM WebSphere Business Integration Adapter for mySAP.com (R/3 Version.4.x) contain a variety of objects, such as table structures, functions, and data. These development objects must be imported into the SAP system to provide the specific functionality required by the ABAP Extension Module. Each transport file is included in a.zip file. For example, the transport file for the SAP R/3 Version 4.x Primary transport is located in the 4_Primary.zip file. See the transport note included in each transport.zip file for detailed information about the transport file. There are seven connector transport files, which are listed in Table 7-11 on page 249. Modifications required by the adapter are handled by these connector transport files. The Primary, Utilities, and Request transport files are required. The following is a list of the SAP R/3 Version 4.x connector transport files. To ensure that all necessary tables are created before the data for those tables is added, install the transports in the order listed. 1. 4_Primary (CWDK900333) 2. 4_Utilities (CWDK900483) 3. 4_Request (CWDK900455) 4. 4_Delivery (CWDK900487) 5. 4_NumberRange (CWDK900337) 6. 4_Tools_Maintenance (CWDK900463) 7. 4_Tools_Development (CWDK900480) The functionality provided by the Primary, Utilities, Request, and Delivery transport files is to make the run-time components. The Tools_Maintenance and Tools_Development transport files can be installed at anytime after the required transport files are installed. They are not required for the run-time environment.
- 291. Chapter 7. Use Case 1: WBIMB using WBI Adapter for mySAP.com 249 Table 7-11 Connector transport files Name of Transport Purpose 4_Primary This transport file contains the development objects, which are loaded only once into the system. It contains the number range objects, the development classes, and the dynamic transaction declaration include program, as well as the restriction include program, which can be used to make customer-specific changes to the triggering logic. Important: If you are applying this transport file to a system that already has the connector running on it, the contents of the transport file may overwrite changes that were made to the existing environment. 4_Utilities This client-independent transport file contains objects and functionality that are shared among the request, delivery, development, and maintenance components. For example, it contains the log and data elements. 4_Request This client-independent transport file contains the functionality required to support business object request operations. 4_Delivery This client-independent transport file contains the functionality required to support event delivery operations, including event triggering and event polling.
- 292. 250 WebSphere Business Integration for SAP Install connector transport files The connector transport files make all the necessary modifications to SAP R/3 by importing programs and other development objects. They do not alter any SAP R/3 programs or modify user exits. To install the transports: 1. Copy the transports to the SAP R/3 application server. There are two kinds of transport files: a. Copy files (control files) that have names beginning with K to the usrsaptranscofiles directory. b. Copy the files (data files) that have names beginning with R to the usrsaptransdata directory. 2. Log in to the SAP R/3 system. a. Import the transport files by using the SAP R/3 transaction STMS (Transport Management System). 4_Number Range This client-dependent transport file contains the four number ranges in their initial state. Use these intervals or create the number range intervals themselves. Note: Re-importing the Number Range transport file initializes the existing number range intervals for the connector. This corrupts the data in the connector’s log, current event, future event, and archive tables if those tables are not refreshed before reusing. This transport file can be installed at any time after the Primary transport has been installed. 4_Tools_Maintenance The functionality required to support maintenance operations, such as displaying the log statistics and event tables. 4_Tools_Development This client-independent transport file contains the functionality required to support the development of objects. Attention: If reapplying transports, any development done prior to reapplying the transport files are overwritten. Name of Transport Purpose

Click Select All, and then click Continue (F2). If you receive the message Programs successfully generated, the transports were successfully imported. 7.6.3 Process the business objects in the ABAP Extension module Business object processing for the extension module is the same for all business objects regardless of the specific native SAP API that is used. For example, if developing a business object based on a Call Transaction or an IDoc, the business object data is processed the same way. The processing is the same whether a business object is sent into the SAP application as a retrieve performed as part of event notification or as a business object request. The business object’s verb also does not change the processing.
- 299. Chapter 7. Use Case 1: WBIMB using WBI Adapter for mySAP.com 257 Business object processing consists of four steps: The connector converts an application-specific business object into a flat structure containing business object data and passes the data to the SAP application. The connector’s function module /CWLD/RFC_DO_VERB_NEXTGEN dynamically routes the business object data to an ABAP handler, for example /CWLD/DYNAMIC_RETRIEVE. The function of an ABAP handler is to get business object data into or out of the SAP application database. The ABAP handler processes the business object data, generates business object response data, and returns new business object data to the connector through /CWLD/RFC_DO_VERB_NEXTGEN. The connector receives the new business object data, and uses the business object definition of the application-specific business object to create a new business object to pass to the integration broker. An overview of the business object processing for sales is shown in Figure 7-71. Figure 7-71 Sales order business object processing
- 300. 258 WebSphere Business Integration for SAP 7.6.4 Create an Event triggering and detection mechanism The Adapter for mySAP.com is event-driven. In order to get events out of SAP R/3, an event triggering mechanism in SAP R/3 must be implemented for each WBI supported business object. Event detection is part of the event triggering process in the ABAP Extension Module. It is the process of identifying that an event was generated in the SAP application. The event detection mechanism calls an event trigger, which takes the detected event and adds it to an event table. Event detection mechanisms support real-time triggering and retrieval of objects. SAP application is tightly integrated with the SAP database and allows very limited access for direct modifications to its database. Therefore, the event detection mechanisms are implemented in the application transaction layer above the database. An event detection mechanism has the ability to make a function module call. In this Use Case, a Business Workflow for event detection is used. Business workflow is a cross-application tool within the SAP application that enables SAP R/3 to integrate business tasks between applications. This tool supplements the existing business functions of the SAP application. The standard functions of SAP can be adapted using business workflow to meet the specific requirements of the desired business function. Workflow uses the Business Object Repository (BOR), which stores the definitions for each SAP object in the application. Determine which SAP Business Object to use for triggering Whenever a SAP sales order is created in this Use Case using the transaction VA01 the business process triggers an event for the business object BO_EVENTRIGGER. Use SAP’s Business Object Repository (transaction swo1) to determine which SAP business object to use for triggering the events. 1. Go to the Business Object Builder using transaction swo1 (see Figure 7-72 on page 259).

Map the SAP Business Object to a WBI Business Object The SAP business object name and event must be mapped to the WebSphere Business Integration business object name (for example, BO_EVENTRIGGER) and a verb (for example, Retrieve). WebSphere Business Integration and SAP uses unique naming conventions for business objects and verbs, and therefore maps the names and verbs. For example, WebSphere Business Integration uses the verbs Create, Retrieve, and Update, and SAP uses CREATED, RETRIEVED, and CHANGED. To map the objects, do the following: 1. Go to CrossWorlds Station and transaction /cwld/home (see Figure 7-80 on page 266).

Therefore, all references to business objects throughout this chapter refer to application-specific business objects. Many of the books in the IBM WebSphere InterChange Server documentation set, including the Business Object Development Guide, cover both environments and therefore refer to both types of business objects.
- 316. 274 WebSphere Business Integration for SAP There are several options to create the Business Object definitions to be used by the WebSphere Business Integration Adapter for mySAP.com: Use the SAP Object Discovery Agent with the Business Object Designer tool to generate a rudimentary set of application-specific business object definitions, which can refine using the Business Object Designer tool. The Object Discovery Agent examines specified objects in the application, “discovers” the elements of those objects that correspond to business object attributes and their attributes, and generates business object definitions to represent the information. The Adapter for mySAP.com can handle SAP standard and customized IDocs, BAPIs, and RFCs. The SAP Object Discovery Agent generates Business Objects by accessing the SAP data repository using the Dynamic Retrieve Module of the adapter. Also, SAP Object Discovery Agent can generate Business Objects using IDoc definition files. Create business object definitions from scratch using the Business Object Designer tool. The following sections shows: How to create a Business Object from the IDoc type MATMAS03 using the SAP Object Discovery Agent and the Business Object Designer tool How to create a Business Object for the ABAP Extension Module from scratch using the Business Object Designer tool 7.7.1 Create Business Object for the ALE module This chapter describes how to create a Business Object using the SAP Object Discovery Agent and the Business Object Designer tool.

Because both connectors are using the same application specific Business Objects for the ALE and ABAP Extension modules they can use the same Business Object definitions. Therefore, it is not necessary to create a second Business Object definition of the IDoc type MATMAS03 for the second connector. 7.7.2 Create Business Object for the ABAP Extension Module Use the Business Object Designer to generate a business object definition from scratch for the ABAP Extension Module. In this Use Case, a simple flat business object was used. To start the Business Object Designer tool, the System Manager must be launched.

Use Case 1: WBIMB using WBI Adapter for mySAP.com 295 7.8 Development of a message flow for the MaterialSynchronization (ALE Module) scenario A message flow application is a program that routes, transforms, and manipulates messages. A message flow is deployed and runs in a broker. This sections describes how to create a message flow that takes a SAP ALE Business Object from one queue and copies values of the SAP ALE Business Object to a second SAP ALE Business Object. The message flow also transforms the Business Object and passes the output SAP ALE Business Object to a second queue. 7.8.1 Create a Message Flow Project Before you start adding and configuring message flow nodes, a project in the Broker Administration Toolkit must be created. Also, a message flow file and a message flow schema must be created: 1. In the Broker Application Development perspective, create a message flow project called MaterialSynchronization_MsgFlowProj: a. Select File → New → Message Flow Project. b. In the Project Name field, type MaterialSynchronization_MsgFlowProj, and then click Finish. A new project called MaterialSynchronization_MsgFlowProj is displayed in the workspace (see Figure 7-113 on page 296). c. Right-click on the Message Flow Project and select New > Broker Schema. Enter a name for the schema, for example MaterialSynchronization_Schema.
- 338. 296 WebSphere Business Integration for SAP Figure 7-113 Create a new message flow project 2. In the Broker Application Development perspective, create the MaterialSynchronization_MsgFlow message flow in the MaterialSynchronization_MsgFlowProj: a. In the Resource Navigator view, click on MaterialSynchronization_MsgFlowProj to highlight it. b. Select File → New → Message Flow. c. Ensure that the Project field contains MaterialSynchronization_MsgFlowProj (see Figure 7-114 on page 297). d. Add the schema. e. In the Name field, type MaterialSynchronization_MsgFlow, and then click Finish.

Use Case 1: WBIMB using WBI Adapter for mySAP.com 297 Figure 7-114 Create a new message flow 7.8.2 Build the message flow This section describes how to implement a message flow and transform business objects using ESQL. Add and connect nodes On the left-side of the Message Flow editor is the Node Palette, which has a list of all the nodes available for to use in the message flow (see Figure 7-115 on page 298).
- 340. 298 WebSphere Business Integration for SAP Figure 7-115 The MaterialSynchronization_MsgFlow message flow nodes. To build the message flow: 1. Make sure that the Selection button (above the Node Palette) is highlighted so that nodes from the Node Palette can be selected. 2. Click the MQInput node to select it from the Node Palette, then click somewhere on the canvas, the white area to the right of the Node Palette, to add the node to the message flow. 3. Repeat steps 1 and 2 to add a Compute node and an MQOutput node to the canvas. To define the order that the nodes process an input message, connect them together, as shown in Figure 7-116 on page 299. Most, though not all, nodes have at least one terminal with which to connect them to other nodes. The MQInput node has three terminals. Hover the mouse pointer over each terminal to highlight it and to display its label. The terminals on the MQInput node are labelled Failure, Out, and Catch.
- 341. Chapter 7. Use Case 1: WBIMB using WBI Adapter for mySAP.com 299 1. Click on the Connection button (above the Node Palette) so that the nodes can be connected together. 2. Click on the Out terminal of the MQInput node. Notice that a thin black line with an arrow head appears. Move the mouse pointer and click on the In terminal of the Compute node so that the arrow connects the MQInput node to the Compute node. 3. Connect the Out terminal of the Compute node to the In terminal of the MQOutput node. The canvas looks similar to the canvas shown in Figure 7-116. 4. To save the MaterialSynchronization_MsgFlow message flow, select File → Save MaterialSynchronization_MsgFlow.msgflow. When saving a message flow file, the Message Brokers Toolkit validates the message flow. The MaterialSynchronization_MsgFlow message flow has two errors, as shown in Figure 7-116, which are indicated by a small white cross on a red background on the MQInput and Compute nodes. The MaterialSynchronization_MsgFlow message flow files and folders in the Resource Navigator view are also highlighted with crosses. Figure 7-116 The MaterialSynchronization_MsgFlow message flow validated. A brief description of each error is given in the Tasks view below the Message Flow editor: The error in the MQInput node is because no name of the input queue, from which the MQInput node takes input messages, was entered. The error in the Compute node is because no ESQL module, which defines how the Compute node process input messages, was created. The following sections describe how the errors can be fixed by configuring the nodes.
- 342. 300 WebSphere Business Integration for SAP 7.8.3 Configure the message flow In the MaterialSynchronization_MsgFlow message flow, the MQInput node takes an input message from the SAPConnector’s Deliveryqueue called SAPCONNECTOR/DELIVERYQUEUE and passes it to the Compute node. After the Compute node has processed the message, the MQOutput node puts the output message to the SAP_2CONNECTOR/REQUESTQUEUE. In the MaterialSynchronization_MsgFlow message flow, when the Compute node receives the input message from the MQInput node, the Compute node builds an output message that contains a copy of the header and transformed content of the input message. To configure the message flow, two WebSphere MQ local queues must have been created (refer to “Define the queues” on page 207): SAPCONNECTOR/DELIVERYQUEUE SAP_2CONNECTOR/REQUESTQUEUE Also, the ESQL module that transforms the message must be implemented. Configure the node properties To configure the properties of a node: 1. Click on the Selection button at the top of the Node Palette. 2. Right-click on the node and then click Properties. Perform steps 1 and 2 to configure each node as follows: Configure the MQInput node To configure the MQInput node: 1. Open the Properties dialog box for the MQInput node (see Figure 7-117 on page 301). 2. On the Basic page in the Queue Name field, type SAPCONNECTOR/DELIVERYQUEUE. 3. On the Default page in the Message Domain field, type MRM. 4. On the Default page in the Message Set field, type the name of the message set and the message set id, for example, MaterialSynchronizationMsgSetProj (NUTU955002001). 5. On the Default page in the Message Type field, type the name of the business object, for example, sap_matmas03. 6. On the Default page in the Message Format, type CwXML.

Save MaterialSynchronization_MsgFlow.msgflow (press Ctrl-S). The error on the MQInput node is no longer displayed. Configure the MQOutput node To configure the MQOutput node: 1. Open the Properties dialog box for the MQOutput node. 2. On the Basic page in the Queue Name field, type SAP_2CONNECTOR/REQUESTQUEUE. The Queue Manager Name field can be left empty because the SAP_2CONNECTOR/REQUESTQUEUE queue is on the same queue manager as the SAPCONNECTOR/DELIVERYQUEUE queue. Click OK to close the Properties dialog box. Configure the Compute node Do not edit any of the properties in the Compute node but take a look at the properties to see what has caused the error: 1. Open the Properties dialog box for the Compute node. 2. On the Basic page of the Properties dialog box, notice that the ESQL Module field contains MaterialSynchronization_MsgFlow_Compute. This value is entered automatically when the node is created because the Compute node must contain some ESQL. ESQL is held in a separate file called, in this case,
- 344. 302 WebSphere Business Integration for SAP MaterialSynchronization_MsgFlow.esql. However, an error is displayed in the Tasks view because the file MaterialSynchronization_MsgFlow.esql does not yet exist. 3. Click Cancel to close the Properties dialog box without saving any changes. The next section describes how to create MaterialSynchronization_MsgFlow.esql and how to write some simple ESQL for the Compute node. 7.8.4 Write ESQL for the Compute node This ESQL demonstrates how to construct a business object for the ALE module of the adapter. All of the ESQL that belongs to a message flow is stored, by default, in a single file. In this case, all the ESQL for the MaterialSynchronization_MsgFlow message flow is stored in a file called MaterialSynchronization_MsgFlow.esql. Before implementing the ESQL, associate the Message Flow Project with the Message Set Project and vice versa. By doing this, the ESQL code compilation feature can be utilized. Also, the graphical mapping feature can be used to transform messages. This section shows you how to implement ESQL natively: 1. Switch to the Resource Perspective. 2. Right-click on the Message Flow Project and select Properties. 3. Switch to Project References and select the Message Set Project. 4. Right-click the Message Set Project and select Properties. 5. Switch to Project References and select the Message Flow Project. 6. Right-click the Message Flow Project and select Rebuild Project. 7. Right-click the Message SetProject and select Rebuild Project. Create the ESQL file To create MaterialSynchronization_MsgFlow.esql, right-click on the Compute node, and then click on Open ESQL. MaterialSynchronization_MsgFlow.esql does not already exist so the Message Brokers Toolkit creates the file in the MaterialSynchronization_MsgFlow Messageflow Project. When the MaterialSynchronization_MsgFlow.esql file is created, it automatically opens in the ESQL editor. When the MaterialSynchronization_MsgFlow.esql file is created, it already contains the minimum ESQL that is needed for the Compute node to
- 345. Chapter 7. Use Case 1: WBIMB using WBI Adapter for mySAP.com 303 successfully validate. If the ESQL file does not automatically generate some ESQL, do the following: 1. Close both MaterialSynchronization_MsgFlow.esql and MaterialSynchronization_MsgFlow.msgflow. 2. Open MaterialSynchronization_MsgFlow.msgflow, and then right-click on the Compute node and click Open ESQL. Save MaterialSynchronization_MsgFlow.esql (Ctrl-S) and then click on the MaterialSynchronization_MsgFlow.msgflow tab to return to the Message Flow editor. The error on the Compute node is no longer displayed and no items relating to this task appear in the Tasks view. Click on the MaterialSynchronization_MsgFlow.esql tab to display MaterialSynchronization_MsgFlow.esql in the ESQL editor again. The MaterialSynchronization_MsgFlow_Compute ESQL module In the MaterialSynchronization_MsgFlow.esql file, there is a single module of ESQL called MaterialSynchronization_MsgFlow_Compute. This is the ESQL module that is referenced from the Compute node Properties dialog box. If another Compute node, or a Database node, is added to the MaterialSynchronization_MsgFlow message flow, a new ESQL module is also created in MaterialSynchronization_MsgFlow.esql for the new node. The ESQL for the MaterialSynchronization_MsgFlow_Compute module is as follows: CREATE COMPUTE MODULE MaterialSynchronization_MsgFlow_Compute CREATE FUNCTION Main() RETURNS BOOLEAN BEGIN --CALL CopyMessageHeaders(); --CALL CopyEntireMessage(); RETURN TRUE; END; CREATE PROCEDURE CopyMessageHeaders() BEGIN DECLARE I INTEGER 1; DECLARE J INTEGER CARDINALITY(InputRoot.*[]); WHILE I < J DO SET OutputRoot.*[I] = InputRoot.*[I]; SET I = I + 1; END WHILE; END; CREATE PROCEDURE CopyEntireMessage() BEGIN SET OutputRoot = InputRoot;
- 346. 304 WebSphere Business Integration for SAP END; END MODULE; The ESQL that is automatically generated does not produce any output. When the Compute node receives the input message, it builds an output message without any content. Therefore, the ESQL must be edited: 1. The fourth line (--CALL CopyMessageHeaders();) and the fifth line (--CALL CopyEntireMessage();) of the MaterialSynchronization_MsgFlow_Compute module are commented out so that the Compute module does not parse them. To uncomment the lines, delete -- from the start of each line. 2. Save MaterialSynchronization_MsgFlow.esql. The Compute node now parses the lines that instruct the Compute node to copy the header and content of the input message to the output message. The message that the MQOutput node puts to the OUT queue has the same content as the message that the MQInput node got from the IN queue. For the Material Synchronization scenario to implement the ESQL, refer to “ESQL module” on page 648. 7.9 Development of a message flow for the OrderEventNotification (ABAP Extension Module) scenario A message flow application is a program that routes, transforms, and manipulates messages. A message flow is deployed and running in a broker. This section describes how to create a simple pass through message flow for the ABAP Extension Module Business Object. 7.9.1 Create a Message Flow Project Before starting, adding, and configuring message flow nodes, a project in the Broker Administration Toolkit must be created. Also, a message flow file must be created: 1. In the Broker Application Development perspective, create a message flow project called OrderEventNotification_MsgFlowProj: a. Select File → New → Message Flow Project. b. In the Project Name field, type OrderEventNotification_MsgFlowProj, and then click Finish (see Figure 7-118 on page 305).

- 352. 310 WebSphere Business Integration for SAP 7.10 Deployment of the message flow applications Deployment is the method used to send message flows to execution groups within brokers. There are two methods of deployment that can be used to deploy resources in the Message Broker Toolkit. There is also an additional method of deploying resources using the mqsideploy utility on the command line; however, this is beyond the scope of this book. This section shows you how to deploy a message flow application to a broker using a broker archive. 7.10.1 Deploy a message broker archive There are several ways to deploy a message broker archive within the Message Brokers Toolkit, although both require that a connection to the Configuration Manager has been established. This section describes how to deploy a archive using the option Deploy File. Deploy a message broker archive using Deploy File Deploy a message broker archive using Deploy File: 1. In the Broker Administration perspective, open the message broker archive file to deploy in the Broker Administration Navigator view (create a file with the file extension.bar, for example, ITSOA_Archive.bar, by selecting New → Message Brokers → Message Broker Archive). 2. Add the message flows MaterialSynchronization_MsgFlow and OrderEventNotification_MsgFlow and the message sets MaterialSynchronization_MsgSet and OrderEventNotification_MsgSet to the broker archive. 3. Save the broker archive file ITSOA_Archive.bar. 4. Right-click on the message broker archive file and select Deploy File from the context menu that is displayed. 5.

Use Case 2: WBISF using WBI Adapter for mySAP.com This Use Case describes how to develop a new business process with WebSphere Studio Application Developer Integration Edition V5.1 and execute it on WebSphere Business Integration Server Foundation. This process is a people-centric enterprise integration approach that incorporates various existing enterprise services to choreograph new business processes. This chapter contains the following topics: Operational model Installation of WebSphere Business Integration components Configuration of WebSphere Business Integration components Development of the business process Deployment of the business process Running the scenario 8
- 370. 328 WebSphere Business Integration for SAP 8.1 Operational model This Use Case describes an Internal Order scenario that utilizes several existing enterprise services and some newly created services to compose a new business process. The run-time environment is a WebSphere Business Integration Server Foundation. The WebSphere Business Integration Adapter for mySAP.com is used to connect to the SAP back-end system and retrieve data. The new process consumes data from the following services: Human Resource system running on SAP and accessed via SAP Remote Function Calls (RFCs) Enterprise Procurement system running on SAP and accessed via SAP RFCs Enterprise policy service exposed with standard Web Services Notification service running on a J2EE application server and accessed via Web Services The business details of this process flow are described in 5.7, “Use Case 2 - Solution overview” on page 126. Any employee is able to start a new internal order process by providing some data and submitting the request. To do so, the user has to be logged in and authenticated via a standard Web browser. The internal order requisition needs the following input data: An order description that has a human readable identifier. Desired delivery date. Employee number. Material number. Order quantity. Delivery plant. These input values are exemplary and do not claim to be a pattern for internal ordering. There are various other combinations that would also make sense. This arrangement is only an example of what data a user has to provide. After submission, the user immediately gets a reply that the request is sent. The status of the request can be monitored to verify where the request is currently processed. The first enterprise service access retrieves the mail address of the originating user from the existing Human Resource system. The second process activity checks if the requested material requires an approval or not. This is done by querying an existing policy system via a Web Service interface. Depending on the reply of the policy service, the order is directly placed in the enterprise
- 371. Chapter 8. Use Case 2: WBISF using WBI Adapter for mySAP.com 329 procurement system or routed to a functional approver. The approver is an authorized employee who can see all incoming requests in a special inbox. Based on the request information, the approver decides to approve or decline a request. If a request is approved, it is routed to the enterprise procurement system where the internal purchase order is placed. The existing notification service is used in any case to inform the requestor about the result of the request. The notification service uses the existing e-mail infrastructure to deliver the result to the correct person. The operational model in Figure 8-1 shows how the subcomponents communicate with each other and where they are physically installed. The Use Case does not provide a custom front-end application. Instead, the standard WebSphere Process Choreographer Web client is used to simulate process invocation, routing, staff interaction, and execution. Figure 8-1 Operational model

- 416. 374 WebSphere Business Integration for SAP 8.4 Development of a business process The section describes the development steps to implement the described Use Case scenario. The scenario utilizes two workbenches. The System Manager is used to generate business objects from the back-end system and to configure the mySAP.com connector. These settings and objects are exported to the file system and imported into WebSphere Studio Application Developer Integration Edition V5.1 (WSADIE). Within WSADIE, a new business process is created that incorporates several encapsulated services. All business process development activities are done in the WebSphere Studio Application Developer Integration Edition V5.1. A prepackaged workspace is used as a starting point, which is delivered in the file Base_Workspace_SAK400.zip. This workspace provides the Notification service out of the box. The exported business object definitions are used to create two enterprise service applications that are integrated into existing back-end systems. A third service project is defined to hold the Web Services Description Language style description of external services. In this Use Case, it is a back-end service exposed via an standard Apache-Axis Web Service interface. 8.4.1 Create Business Objects and Connector Configuration This section describes the steps necessary to create the required business objects using the Eclipse based System Manager, the Business Object Designer, and the Connector Configurator. 1. Open the System Manager from the Windows Start Menu. The window in Figure 8-60 on page 375 should appear. Attention: The focus of this Use Case is to show how easy it is to choreograph new business processes using WebSphere Business Integration Server Foundation by incorporating existing enterprise services. Exception handling and input validation is purposely limited to a minimum. It is highly recommended to implement more application specific exception handling to handle back-end errors and warnings more efficiently.

Use Case 4: Integration of SAP XI with WBI InterChange Server This chapter describes the implementation of Use Case 4, CustomerDataRepository, and demonstrates how to exchange documents between Lotus Domino databases and SAP R/3 using two Integration Brokers, IBM WebSphere InterChange Server, and SAP Exchange Infrastructure in between. The chapter starts with an overview of the underlying business process. Based on this introduction, the operational model is described. After that, the configuration of the predominant building blocks of the implementation, WebSphere Business Integration adapter for Lotus Domino, WebSphere Business Integration adapter for SAP Exchange Infrastructure, and SAP Exchange Infrastructure itself, are covered. The chapter ends with a description of how to run the overall scenario. 10
- 598. 556 WebSphere Business Integration for SAP 10.1 Overview of Use Case CustomerDataRepository The business process that underlies Use Case CustomerDataRepository is depicted in Figure 10-1. Figure 10-1 Business process model of Use Case CustomerDataRepository 1. The process starts when a document representing customer data is created or updated in the Lotus Domino database Customer Contacts. 2. New or updated documents within this database are detected by the WebSphere Business Integration adapter for Lotus Domino and transferred to the WebSphere InterChange Server. Therefore, Domino documents get converted into an InterChange Server internal data format called a DominoDocument business object. 3. Within the WebSphere InterChange Server, the application dependent business object DominoDocument is mapped into a generic business object Customer before it get processed by a collaboration object (Figure 10-2 on page 557). A collaboration object represents an WebSphere InterChange Server internal business process. For the implementation described in this chapter, the process is left rather simple in that it just copies business objects from its input to its output port. 1 SAP Exchange Infrastructure SAP R/3 6 54 IBM WebSphere Business Integration InterChange Server 2 Lotus Domino Server Customer Contacts Database

The Customer business object is mapped to a DEBMAS01 business object, which is an XML representation of a SAP IDoc structure DEBMAS01. After that, the DEBMAS01 business object is transmitted as a XML message by the WebSphere Business Integration adapter for SAP Exchange Infrastructure, using JMS as the underlying transport mechanism. 5. At the SAP Exchange Infrastructure, the XML message is received by the corresponding JMS adapter and relayed to the IDoc adapter, where it gets converted into an IDoc of type DEBMAS01, before it is forwarded to the SAP R/3 back-end system (Figure 10-3). 6. Finally, this IDoc instance is inserted into the SAP R/3 internal database.

- 600. 558 WebSphere Business Integration for SAP 10.2 Operational model for CustomerDataRepository As has been shown in Figure 10-1 on page 556, the implementation of Use Case CustomerDataRepository consists of four major building blocks: The Domino Server for the creation of Customer documents The WebSphere InterChange Server receiving documents from the Domino Server and relaying them to the SAP Exchange Infrastructure as XML messages The SAP Exchange Infrastructure that receives XML messages from the WebSphere InterChange Server and forwards them to the SAP R/3 as a back-end system The SAP R/3 that is responsible for processing the business logic Each of the four major building blocks is installed and configured on a dedicated node, as shown in Figure 10-4. For each node, the operational model lists the installed software systems that are relevant to the implementation of the described Use Case. . Figure 10-4 Operational model: CustomerDataRepository implementation This chapter assumes that the systems shown in Figure 10-4 are already installed on their respective nodes. Therefore, it only covers the configurations of these systems as far as the implementation of this Use Case is concerned. In particular, it is assumed that the WebSphere InterChange Server is installed on node ITSOC according to the description given in Chapter 9, “Use Case 3: WICS using WBI Adapter for mySAP.com and JDBC” on page 465. When configuring the WebSphere InterChange Server, use the host specific values shown in Table 10-1 on page 559.

If, during the installation, the name of the WebSphere InterChange Server and the destination folder is required, the same name must be chosen as that of the WebSphere InterChange Server. Furthermore, the following WebSphere InterChange Server components, which are provided as their own installation packages, must be installed: The XML Data Handler V2.5.2 The IBM WebSphere Business Integration Collaboration Foundation Finally, a Lotus Notes Version 6 client must be installed on ITSOC for configuring the adapter for Lotus Domino and running the Use Case scenario. 10.3 Configuring the adapter for Lotus Domino This section describes the configuration and testing of the WebSphere Business Integration adapter for Lotus Domino (adapter for Lotus Domino for short). It starts with the introduction of the architecture of the adapter for Lotus Domino. It then covers the configuration of the Domino server and the configuration of the adapter itself. Before integrating the adapter into the overall implementation, it is tested separately. The last part of this section introduces the testing methodology applied within this chapter. Before covering the adapter for Lotus Domino in more detail, the general architecture of a connector is described. A connector consists of an application specific part, the connector agent, and a more generic part, the connector controller (Figure 10-5 on page 560). Name Value hostname ITSOC InterChange Server name ITSOC_WICS WebSphere MQ queue manager itsoc.queue.manager
- 602. 560 WebSphere Business Integration for SAP Figure 10-5 Components of a connector The connector agent communicates with the back-end system using its native formats and protocols, and converts application data, which it exchanges with the back-end system, into the WebSphere InterChange Server internal format of a business object. This business object, which the agent creates, is still dependent on the application. If the back-end system sends and receives data of different formats, the connector agent must be configured to handle business objects of different types. The connector agent sends the application dependent business object to the connector controller either using WebSphere MQ, JMS, or CORBA IIOP. Driven by the defined map, the application dependent business object is transformed into a generic business object within the connector controller, before it is submitted to a collaboration object.

- 603. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 561 10.3.1 The architecture of the adapter for Lotus Domino The adapter for Lotus Domino supports bidirectional exchange of Lotus Domino documents with external back-end systems using the WebSphere InterChange Server as an intermediate broker. It supports event processing, meaning it automatically transfers new or updated documents to the WebSphere InterChange Server, as well request processing, which allows external back-end systems to store their data in a Lotus Domino database. Figure 10-6 on page 562 gives an overview of the components involved in processing the events occurring within the Lotus Domino database Customer Contacts. The following steps are executed: 1. Part of the adapter is a special process, the Event Listener, and an Event Table, a Lotus Domino database. The Event Listener monitors the Lotus Domino database Customer Contacts for new, deleted, or updated Customer documents. If the Event Listener detects such an event, it stores it as an event document in the Event Table database. 2. The connector agent of the adapter for Lotus Domino polls the Event Table for unprocessed documents. 3. Having detected a new event document, the connector agent retrieves the corresponding customer document from the Customer Contacts database. 4. The connector agent converts the retrieved Domino document into a DominoDocument business object and submits it to the connector controller. 5. The connector controller converts the application specific business object DominoDocument to a generic business object Customer before relaying it to the WebSphere InterChange Server for further processing. The steps for request processing are similar. Since the implementation of the CustomerDataRepository only comprises event processing, these steps are not elaborated on in more detail.
- 604. 562 WebSphere Business Integration for SAP Figure 10-6 Architecture of the adapter for Lotus Domino for event processing 10.3.2 Configuring the Domino server for the adapter The implementation of Use Case CustomerDataRepository requires a Lotus Domino server on node ITSOE that hosts the Customer Contacts database (Figure 10-4 on page 558). Besides creating the Customer Contacts database, the configuration of this Domino server itself must be modified in order to support the event processing, as described in 10.3.1, “The architecture of the adapter for Lotus Domino” on page 561. The steps comprise the configuration of a technical user that the adapter needs for accessing the Domino server and the installation of the event processing parts. Technical user for the adapter for Lotus Domino The adapter for Lotus Domino uses the credentials of the Domino user Domino Adapter for accessing the Domino databases. Ensure that this Domino user exists and that it has the right to run restricted and unrestricted Java agents on the Domino server. The latter must be specified within the server configuration document in the Domino Directory database on the Domino server.

Creating the Customer Contacts database The Customer Contacts database is created using the standard Lotus Notes database template Personal Address Book. This template provides the contact form that defines the structure of customer documents. To create the database: 1. Call the tool Lotus Domino Designer® and log in with a user with manager privileges. 2. Within the Lotus Domino Designer, click on the button Create a new database. The window New Database opens, where the new Customer Contacts database is specified, as depicted in Figure 10-7 on page 564, and press OK. After creation, configure the access privileges for the technical user Domino Adapter so that the adapter can access the database subsequently. This configuration is done using the Lotus Notes client with a user that has Manager privileges on the newly created Customer Contacts database.

Use Case 4: Integration of SAP XI with WBI InterChange Server 567 10.3.3 Configure the Domino connector Configuring an WebSphere InterChange Server adapter for receiving or sending business objects usually consists of the following steps: Definition of the application dependent and generic business object types Definition of maps between the application dependent and generic business object types Configuration of the connector configuration itself For testing a connector configuration, a collaboration object has to be defined additionally. All these configurations are performed from within the System Manager that provides an Eclipse-based development and management environment for the WebSphere InterChange Server development projects. As depicted in Figure 10-11, the system manager offers various tools for developing integration applications, managing the components of an application in integration libraries and user projects, and deploying the application on the WebSphere InterChange Server. This section starts with a setup of the System Manager environment. Subsequently, configuration of the business objects are described. After that, the map specification is introduced. Finally, this section ends with a description of a test procedure for the adapter.

Figure 10-13 Name the new integration library Configure the business object DominoDocument The configuration of the connector for Lotus Domino requires an application dependent business object type DominoDocument and a generic business object type Customer (Figure 10-6 on page 562). The business object type DominoDocument provides a complete description of all fields of a document within a Domino database. An instance of a DominoDocument consists of an array of DominoItem child business objects that each represent the description and contents of a single field within the Domino document (Figure 10-14 on page 569).

Press the Save button and close the Business Object Designer tool.
- 612. 570 WebSphere Business Integration for SAP Figure 10-16 DominoDocument business object type in Business Object Designer Create the business object Customer The implementation of Use Case CustomerRepositoryData requires a mapping between input data of type DominoDocument to output data of type DEBMAS01 within the WebSphere InterChange Server (Figure 10-2 on page 557). In order to limit the number of mappings, in particular for a multi-party scenario, the WebSphere InterChange Server supports a two-step mapping scheme. Therefore, incoming application dependent data is mapped onto a generic business object, which is converted, after some internal processing, into the application-dependent structure of the receiving side. The generic business object Customer, which is defined for the CustomerDataRepository scenario, contains the essential information that is going to be conveyed from the Customer Contacts database to the SAP R/3

- 614. 572 WebSphere Business Integration for SAP Figure 10-19 Customer business object type in the Business Object Designer Define the map from DominoDocument to Customer Having specified the generic business object, the next task is to specify the mapping from the DominoDocument to Customer business object type (Figure 10-6 on page 562). This mapping, called DominoDocument_Customer, is defined using the Map Designer tool, which offers a graphical development tool for creating and modifying maps. A map is made up of a series of transformations that define how to calculate the value of each attribute in the destination business object. The map designer tool supports simple transformation steps, such as copying a source attribute to a destination attribute, as well as the development of customized transformations directly in Java. The latter is applied for the DominoDocument_Customer mapping, since in this case there is only an indirect correspondence between the attributes of the DominoDocument and Customer business objects, as is illustrated in Figure 10-20 on page 573.
- 615. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 573 Figure 10-20 Mapping of a DominoDocument to a Customer business object As has been shown in Figure 10-14 on page 569, the overall business object DominoDocument contains an array of DominoItem business objects. Each DominoItem business object represents a field within a Contact document of the Domino database Customer Contacts. The attribute Name of the DominoItem business object contains the name of the field it is representing. Each DominoItem contains a child business object DominoItemValue that holds the field value within its attribute value. Based on these structures, the algorithm for performing the DominoDocument_Customer mapping must traverse the DominoDocument business object and check whether a DominoItem describes an attribute in the Customer business object. The details of this algorithm are specified in pseudo-code in Example 10-1 on page 574. DominoDocument NoteID = 986 DatabaseName = customer.nsf ServerName = ITSOE . . . Items = . . . DominoItem[n] Name = FirstName Type = String Values = . . . DominoItem[n+1] Name = LastName Type = String Values = . . . DominoItem[0] . . . Value = Hans DominoItemValue[0] Value = Meier DominoItemValue[0] Customer . . . FirstName = Hans LastName = Meier . . . DominoDocument_Customer Mapping
- 616. 574 WebSphere Business Integration for SAP Example 10-1 Pseudo code for the DominoDocument_Customer mapping for each DominoItem array element in DominoDocument if (the value of the attribute “name” holds the name of an attribute of the business object “Customer”) then this attribute of the business object “Customer” gets the value of the related “Value” attribute within the child business object “DominoItemValue” assigned. An exception to the processing of the above is exclude ObjectEventId from mapping, because this attribute is used by the WebSphere InterChange Server for its internal processing purposes In the following steps, the custom mapping is defined using the map designer tool. Thereby, a simple map is created first, which is then refined using Java code and given mapping-classes. 1. Open the map designer tool by selecting Create New Map... from the context menu of the Maps folder within the CustomerDataRepository_Lib (Figure 10-21). Figure 10-21 Create a new map 2. A window with New Map with the name of the Integration library appears; accept this name and press Next. 3. Select the source DominoDocument as the source of the map and press Next (Figure 10-22 on page 575).

In the next window, select Customer as the destination business object and press Next. 5. Finally, name the map DominoDocument_Customer (Figure 10-23), select the mapping direction as being Application-Specific to Generic, and press Finish (see Figure 10-23). Figure 10-23 Name the map “DominoDocument_Customer”
- 618. 576 WebSphere Business Integration for SAP The map designer tool appears, in which the DominoDocument_Customer map is specified. As a first step, define a Move transformation for the Verb and the ObjectId attributes (Figure 10-24). Figure 10-24 Move transformation for the Verb and ObjectId attributes 6. Within the Diagram tab, select the source attribute Verb. 7. Use Ctrl-Drag to move the destination attribute Verb within the destination Customer. Repeat this step for source attribute NoteId and destination attribute ObjectId. As a result, blue arrows from the source to the destination with the rule Move are displayed. Having defined the Move transformations, the mapping for the other attributes must be developed according to the outline in Example 10-1 on page 574. The implementation of this algorithm is an example of a custom transformation, which contains the Java code to transform the source attributes to the destination attributes. The Java code is entered using the Activity Editor, which is part of the Map Designer Tool, and using the Java classes that are part of the WebSphere InterChange Server Mapping API. Define the initial custom transformation by dragging an arbitrary source attribute onto an arbitrary destination attribute. As a result, a custom rule is displayed behind the source attribute (Figure 10-25 on page 577). Note: Even though the custom transformation is independent of any attributes of the source and destination business objects, this initial custom transformation has to be specified in order to be able to open the Activity Editor.
- 619. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 577 Figure 10-25 Define the initial custom map Right-click on the Custom symbol within the Rule column and select View Source. This opens the Activity Editor in its Java view, displaying the Java source code that the map designer generated for the transformation just specified. In this view, switch to the edit mode by selecting Tools → Edit Code and replace everything in there with the Java snippet shown in Example 10-2 on page 578. This code implements the algorithm sketched in Example 10-1 on page 574 in that it uses the WebSphere InterChange Server MAP API to access the attributes of the different source and sink business objects. Save the code and close the Activity Editor. In Map Designer Tool again, switch to the Table tab. Define the execution order of the transformation here, as shown in Figure 10-26. This is important, because otherwise the custom transformation would overwrite any other transformation.

A collaboration can perform various types of Java operations, ranging from simple data piping processing, in which data get copied from a source to a sink without any filtering or verification, to complex synchronizations from various data sources. For Use Case CustomerDataRepository, only the simple data-piping processing is required.
- 625. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 583 The development of collaborations is divided into the development of a collaboration template and the configuration of a collaboration object. A collaboration template contains the actual code of a collaboration (Figure 10-33). It consists of: Ports that determine the input and output business object types Scenarios that specify the processing of business objects Triggering events that define which scenarios are started by the arrival of a business object with a certain verb Scenarios might be specified graphically within the WebSphere InterChange Server Process Designer tool using a UML like notation called an activity diagram. From this activity diagram, Java code is generated. Figure 10-33 Components of a collaboration template Customer.Update Customer.Create Triggering Events: Scenario: Main Port: To BO Type: Customer Port: From BO Type: Customer
- 626. 584 WebSphere Business Integration for SAP A collaboration object is an instantiation of a template in which the ports get associated with a certain connector. For example, given that a template for the required “data piping” processing is available, a collaboration object can be defined that receives customer business objects from the Domino connector and pipes them to another connector by merely associating the From-Port with the DominoConnector and the To-Port with the other connector. With WebSphere InterChange Server there are many templates readily available for different business scenarios. Therefore, templates do not have to developed from scratch, but are gained by adjusting an existing one to given requirements. One of the basic templates is the CollaborationFoundation template that either is installed together with WebSphere InterChange Server or separately. The CollaborationFoundation template is a tool that facilitates the development of various user-defined collaborations. It also supports data-piping as default processing and can be configured to use different business flows by means of property variables. The template provides three ports, two of which, the To and From port, are actually used in the Use Case implementation. Follow the instructions below for installation and configuration of CollaborationFoundation: 1. The installation of the CollaborationFoundation provides a repository file for the CollaborationFoundation template in the directory C:WICSCollaborationFoundation. Import this file by selecting Import From Repository File from the context menu of the library CustomerDataRepository_Lib (Figure 10-34). Figure 10-34 Import from Repository File 2. Enter the installation directory of the CollaborationFoundation template (Figure 10-35 on page 585).
- 627. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 585 Figure 10-35 Enter the installation directory of CollaborationFoundation 3. As a result, the CollaborationFoundation appears under Category Collaboration Templates. Double-clicking on the CollaborationFoundation opens it in the Process Designer tool. Using this tool, the Customer business object is assigned to the existing ports. 4. Within the left pane of the Process Designer tool, open the CollaborationFoundation folder and double-click on Definitions. Since the template is defined with a default business object Controller, a warning window appears asking to remove the existing ports. After clicking No three times, the Template Definition window appears (Figure 10-36). 5. Within that window, go to the tab Ports and Triggering Events where the associations of the ports to business objects are defined. Select the port type Customer from the drop-down list in the BO Type column for each port. 6. In the same window, assign the events, meaning the arrival of Customer business object with a certain verb, that trigger the execution the Main scenario that is defined in the CollaborationFoundation template. Do this using the drop-down list in the Verb column. In this case, associate the Verbs Create, Delete, and Update with the Main scenario (Figure 10-36). Figure 10-36 Associate Customer business object & Collaboration Foundation ports 7. Apply the changes. Then compile the generated Java Code by selecting Compile from the File menu and saving the template to the project by selecting File → Save → To Project.

This test is conducted using the tool Visual Test Connector (VTC), which is delivered with IBM WebSphere InterChange Server. The VTC simulates the activities of an arbitrary connector. The VTC is configured with the configuration profile of the connector to be simulated. It provides a Graphical User Interface for sending and receiving those business objects that the connector understands to the WebSphere InterChange Server; it behaves exactly as the connector it simulates. Note that testing a connector within the VTC tests only the right configuration of a connector. A convenient scenario for testing the communication between the connector and its back-end system as well is depicted in Figure 10-37. Figure 10-37 Using the Visual Test Connector In this scenario, the VTC is used as a driver that receives and sends business objects from a “real” configuration of the Domino connector, which is directly connected to its Domino server. Internally, the VTC is configured with a PortConnector that represents a connector with no underlying code and as such is very well suited for simulation scenarios. Thus, the VTC together with the PortConnector is used as a representative of the SAP Exchange Infrastructure system. Taking this approach, the port connector can be replaced by the adapter for SAP Exchange Infrastructure without any change to the configuration of the connector for Lotus Domino. The next paragraph covers the configuration of the PortConnector. Since deployment of the library CustomerDataRepository to the WebSphere InterChange Server and the definition of a collaboration object are prerequisites of this test, these topics are described subsequently.

Use Case 4: Integration of SAP XI with WBI InterChange Server 587 Configure the PortConnector The configuration of the PortConnector consists of only standard but no connector specific properties. It is obtained by copying the configuration of the DominoConnector, deleting all its connector specific properties, and configuring it to support the Customer business object: 1. Make a copy of the DominoConnector under the name PortConnector. For this purpose, open the Connector Configurator by double-clicking DominoConnector in the CustomerDataRepostory_Lib, select File → Save as → To Project, name it PortConnector, and press Save (Figure 10-38). Figure 10-38 Get PortConnector as a copy of DominoConnector 2. The next steps are performed on the PortConnector copy. Click on the Standard Properties tab, and change the property ApplicationName to PortConnector (Figure 10-39). Figure 10-39 Enter PortConnector as ApplicationName

Likewise, switch to the Supported Business Objects tab, and delete all rows except for the Customer business object name. 5. Save the configuration to the project by selecting File → Save → To Project, as well as File → Save → To File, and enter the file name, for example, C:WICSrepositorysak400DominoPortConnector.cfg. Note that for the communication between the connector agent of the PortConnector and its connector controller, a WebSphere MQ queue AP/PORTCONNECTOR/ITSOC_WICS must be configured (see “Prepare WebSphere MQ for the test” on page 589). Define a collaboration object Testing the Domino Connector, as shown in Figure 10-37 on page 586, requires a collaboration object that pipes Customer business objects from the DominoConnector to the PortConnector. Create this collaboration object from the template CollaborationFoundation by performing the following steps: 1. Within the library CustomerDataRepository_Lib, navigate to the Collaboration Objects, right-click on it and select Create New Collaboration Objects... (Figure 10-40). Figure 10-40 Create New Collaboration Object 2. In the Create New Collaboration window, highlight the CollaborationFoundation template, enter Domino2PortConnectorCollaboration as the collaboration object name, and press Next. 3. In the Bind Ports window, bind the From port to the DominoConnector and the To port to PortConnector, as shown in Figure 10-41 on page 589. Since all ports of a collaboration object must be bound, also bind the DestinationAppRetrieve port, even though it is not used within this scenario.

Before starting the deployment, connect the WebSphere InterChange Server to the system manager. 1. Ensure that the WebSphere InterChange Server is started. If it is not, start the PersistentNameServer first and then start the InterChange Server. 2. Ensure that the WebSphere InterChange Server instance ITSOC_WICS is registered with the system manager. If not, navigate to the InterChange Server Component Management pane within the system manager and call Register Server from the context menu of the folder InterChange Server Instances (Figure 10-43). Figure 10-43 Start registering the ICS to the system manager 3. Within the Register, new server windows specify the ICS instance, as shown in Figure 10-44, using the default user ID and password.

Figure 10-49 Deploy CustomerDataRepository_Proj 5. A return message is displayed that the connector was deployed successfully. The message might contain a hint that a collaboration object cannot be activated because its publisher (the connector) is not available. The reason for this is that the components of the user project get deployed in a different order than is required. In order to fix this problem, either deploy the components in a successive order or restart the WebSphere InterChange Server. 6. For the latter, select Shutdown → Gracefully from the context menu of the instance ITSOC_WICS (Figure 10-50 on page 593). Note: It is a good practice to delete an existing deployed project before deploying a new one. If this is done, do not forget to restart the server

- 640. 598 WebSphere Business Integration for SAP 10.4 Configure the adapter for SAP XI To complete the implementation of Use Case CustomerDataRepository, the WebSphere Business Integration adapter for SAP Exchange Infrastructure V1.0 (adapter for SAP XI for short) is configured to exchange XML messages that represent IDocs of type DEBMAS01 with SAP Exchange Infrastructure. This section starts with a description of the architecture of the adapter for SAP Exchange Infrastructure. It then describes the generation of business objects of type DEBMAS01. Subsequently, the mapping of Customer business objects to the DEBMAS01 business objects is covered. Then, the definition of the meta-objects for configuring the connector and the connector itself are described. Note that the configuration of SAP Exchange Infrastructure, which is a back-end system from the WebSphere InterChange Server’s perspective, is described in 10.5, “Configure SAP Exchange Infrastructure” on page 611. The test of the adapter for SAP Exchange Infrastructure is postponed to the end of that section. 10.4.1 The architecture of the adapter The adapter for SAP Exchange Infrastructure V1.0 allows the WebSphere InterChange Server to asynchronously exchange business objects with SAP Exchange Infrastructure using a WebSphere MQ based JMS implementation. Figure 10-59 gives an overview of how requests from the WebSphere InterChange Server to SAP Exchange Infrastructure are processed by the adapter. Figure 10-59 Request processing of the adapter for SAP XI On receiving a business object that represents a request from the WebSphere InterChange Server, the adapter for SAP Exchange Infrastructure calls the XML data handler that converts the business object into an XML message. The XML message is determined by the business object type that the adapter is WBI_XI_Queue XML Message WBI InterChange Server WBI Adapter for SAP XI XML Data Handler SAP XI Business Object
- 641. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 599 associated with. This XML message is put into a WebSphere MQ queue. There the JMS layer makes the appropriate calls to open a queue session and routes the message. Event processing, in which the adapter receives XML messages from SAP Exchange Infrastructure and relays them to the WebSphere InterChange Server, works similar to the request processing described before. Both kinds of processing are metadata driven, meaning that major format conversions and message routing functions are defined by meta-objects. 10.4.2 Generate Business Object Definitions A WebSphere Business Integration adapter is configured to transport business objects of a defined type. In the case of the adapter for SAP Exchange Infrastructure, the type of its configured business objects is derived from IDocs. These IDocs are defined by SAP or self-defined. The IDoc structure can be downloaded from an Interface Repository available on the Internet at http://ifr.sap.com, or imported from the repository of the SAP Exchange Infrastructure system that is used for the implementation of this Use Case. The latter approach, which is described in 10.5.8, “Import the XML schema for DEBMAS01” on page 639, is recommended, since it ensures that the XML messages generated by the WebSphere InterChange Server are compatible with the IDoc structures that the SAP back-end system uses. Regardless of which of the two approaches is taken, the result is a XML schema representing the IDoc structure. Business object types can be generated from a XML schema using the WebSphere InterChange Server tool XML Object Discovery Agent (ODA). This section assumes that an XML schema for DEBMAS01 is available in the file debmas01.xsd and shows how to use the XML Object Discovery Agent for generating the business object type from this file. 1. Launch the XML object discovery agent (ODA) from the program menu by selecting Start → Programs → IBM WebSphere Business Integration Adapters → Adapters → Object Discovery Agent → XML Object Discovery Agent. As a result, a DOS window is opened, displaying that the XML Object Discovery Agent is listening on port 57037. 2. Open the library CustomDataRepository_Lib in system manager, navigate to the folder Business Objects, and select Create New Business Objects... (Figure 10-15 on page 569). 3. The Business Object Designer opens. Press Cancel when the pop-up window for New Business Object appears. Then select File → New Using ODA (Figure 10-60 on page 600).

The Business Object Wizard appears with the located agent displayed (if not, then press Find Agents). Pressing on the agent fills the agent’s host and port (Figure 10-61). Figure 10-61 Select XML ODA Agent 5. After pressing Next, a window appears showing that the essential parameters for generating business objects are configured. Within the Value column, fill in the FileName property with the fully specified name of the XML schema file, which has been imported before (Figure 10-62 on page 601).
- 643. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 601 Figure 10-62 Enter the file name of the DEBMAS01 XML schema file 6. In the next window, select the XML top level object DEBMAS01 as the source node from which the Object Discovery Agent generates business object definitions (Figure 10-63). Confirm this selection on the next page, and press OK on the next window, where properties for all business objects selected might be specified. Figure 10-63 Select DEBMAS01 as the source node for ODA generation 7. If the generated business objects are saved to the project in step 6, it fails to validate the utmost business object definition for DEBMAS01 because it misses at least one key attribute. Click on the option to open the new business objects in a separate window (Figure 10-64). Figure 10-64 Save generated business object to CustomerDateRepository library
- 644. 602 WebSphere Business Integration for SAP 8. The DEBMAS01 business object is shown in the Business Object Designer. Click on the ROOT attribute as a key attribute and save it to the library by selecting File → Save. As the result, the hierarchical business object type DEBMAS01 with several child business objects definitions are generated (Figure 10-65). Figure 10-65 Select ROOT attribute as key for business object DEBMAS01 10.4.3 Define the map Customer_Debmas01 The adapter for SAP Exchange Infrastructure is connected to the adapter for Lotus Domino using a collaboration object of template CollaborationFoundation, which pipes Customer business objects from one connector the other (Figure 10-2 on page 557). Since the adapter for SAP Exchange Infrastructure sends XML messages generated from DEBMAS01 business objects, its respective connector controller must map a generic Customer business object to an application specific DEBMAS01 business object For this purpose, the map Customer_Debmas01 is defined. Therefore, only the standard attribute transformations Move, which copies a source attribute to the destination attribute, and Set value, for assigning constant values, are used (Figure 10-66 on page 603).
- 645. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 603 The sinks of the mapping are determined by the structure of the hierarchical IDoc type DEBMAS01 as defined by SAP. The different components of a DEBMAS01 type, called segments, describe various kinds of customer data. As shown in Figure 10-65 on page 602, the XML Object Discovery Agent generates child business object types for each segment. For the implementation described within this chapter, it has been chosen to map source attributes to different child business object types, as indicated within the Comment column in Figure 10-66. Source attributes that describe more common company information are mapped to attributes within child business object E1KNA1M. The corresponding segment is meant to contain master customer basic data. Source attributes that describe the customer contact itself are mapped to attributes within child business object E1KNVKM. The corresponding segment is defined to contain master customer master contact person data. Figure 10-66 Definition of map Customer_Debmas01 Perform the following steps for defining the map: 1. Select Create New Map... from the context menu of the Maps folder within the library CustomerDataRepository_Lib (Figure 10-21 on page 574). 2. The Create New Map wizard opens. Select CustomerDataRepository_Lib as the project, and press Next. 3. Select Customer as the source business object on the next page and press Next.
- 646. 604 WebSphere Business Integration for SAP 4. Select Debmas01 as the destination business object on the next page and press Next. 5. Enter the name Customer_Debmas01 for the map and select Generic to Application Specific as the mapping direction. Press Finish. The Map Designer window opens (Figure 10-67). 6. Define the map there as shown in Figure 10-66 on page 603 and save the map. Figure 10-67 Name map Customer_Debmas01 and select Mapping Direction 10.4.4 Configure the configuration meta-object In contrast to the Domino connector that processes business objects of just one type, the connector for SAP Exchange Infrastructure is supposed to handle business objects of various types. For event processing, this means that the adapter must be able to map different message types from SAP Exchange Infrastructure to different business object types of the WebSphere InterChange Server. For request processing, the adapter must be able to allocate messages derived from various business objects to various queues. And for both directions, it might be necessary to support different message formats (most of the time, the format is XML, but you should not be limited to it). These additional configuration properties are specified in a format that conforms to a business object structure. Since these business objects contain data that describe how to handle other business objects, they are also called meta-objects. 1. To create a configuration for a meta-object for the adapter, select Create New Business Objects... from the context menu of the Business Objects folder within the CustomerDataRepository_Lib (Figure 10-15 on page 569).
- 647. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 605 2. The New Business Object window opens. Fill in the name MO_SAPXIConnector for the new meta-object and press the OK button (Figure 10-68). Figure 10-68 Name the meta-object MO_SAPXIConnector 3. The Business Object Designer window opens with a new business object definition. Right-click on the first row of the business object definition and select Insert above (Figure 10-69). Figure 10-69 Insert new row in MO_SAPXIConnector 4. For the new row, set the column values as defined in the new row with the entries shown in Figure 10-70. The entries specify the queues, which the adapter uses to send XML messages to SAP Exchange Infrastructure. Figure 10-70 Define values for MO_SAPXIConnector
- 648. 606 WebSphere Business Integration for SAP 10.4.5 Configure the XML data handler meta-object The XML data handler is a data conversion module whose primary role is to convert business objects to and from XML documents (Figure 10-59 on page 598). Its usage from within the connector for SAP Exchange Infrastructure is configured by means of data handler meta-objects. The installation of the XML data handler delivers a template from which the meta-object can be created: 1. Open the library CustomerDataRepository_Lib within the system manager and select Create New Business Object... from the context menu of the folder Business Objects (Figure 10-15 on page 569). 2. Within the Business Object Designer, select File → Open From File..., browse to the file C:WICSDataHandlersrepositoryDataHandlersMO_DataHandler_XML.txt, and open it. 3. The hierarchical meta-object MO_DataHandler_Default with references to a child-object MO_DataHandler_DefaultXMLConfig appears within the Business Object Designer (Figure 10-71 on page 607). Set the attribute BOPrefix to blank, since in this implementation no prefix is used for the generated business objects. Leave all other values as provided by the template. The meta-object contains two important entries: The attribute ClassName specifies the data-handler class to use with the specified MIME type (text_xml, in this case). The attribute NameHandlerClass defines the class name of the name handler, which is responsible for extracting the name of a business object from the root element of an XML message during event processing of the adapter. Note: Since the implementation described here only consists of request processing of one business object type, the contents of the meta-object MO_SAPXIConnector can be kept simple. However, configuring meta-objects provide much more functionality, in particular for event processing.

Within the library CustomerDataRepository_Lib, position the cursor on Connectors node and choose Create New Connector... in the context menu (Figure 10-27 on page 579). 2. As before, press Cancel on the pop-up window New Connector. Within the Connector Configurator window, select File → Open → From File, browse to the file C:WICSrepositorySAPXIBIA_CN_SAPXI.txt, and press Open. 3. The template opens in the Connector Configurator. Leave the Standard Properties as given within the template. They are identical to the standard properties of the DominoConnector, except for those values shown in Table 10-6.

The meaning and creation of the queues are explained in Example 10-6 on page 610. Figure 10-72 Connector specific properties of the SAPXIConnector 5. Also ensure that you put in the name of the configuration meta-object MO_XIConnector as a value of the property ConfigurationMetaObject and the value MO_DataHandler_Default for the property DataHandlerConfigMO. 6. Select the tab Supported Business Objects and specify the meta-objects as well as the application specific and generic business objects that the connector works on (Figure 10-73 on page 609).
- 651. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 609 Figure 10-73 Supported business objects for the SAPXIConnector 7. Note that the connector agent does not support the generic business object Customer, since the mapping, which is selected using the tab Associated Maps (Figure 10-74), is performed by the connector controller. Figure 10-74 Specify “Customer_Debmas01” as associated maps 8. Finally, change the values within the Messaging tab according to the ones displayed in Figure 10-32 on page 582. 9. After you are finished with the configuration, save the connector configuration to the project CustomerDataRepository_Lib as SAPXIConnector and also save it to a file location, as, for example, C:WICSrepositorysak400SAPXISAPXIConnector.cfg. This configuration file is needed later on for starting the connector.
- 652. 610 WebSphere Business Integration for SAP 10.4.7 Create WebSphere MQ queues As shown in Figure 10-75, the adapter shares, with SAP Exchange Infrastructure, the queue WBI_XI_Queue for request processing and, if needed, the queue XI_WBI_Queue for event processing in which the adapters receives XML messages from SAP Exchange Infrastructure. Figure 10-75 Shared queues between SAP XI and WBI Adapter for SAP XI The WebSphere Business Integration Adapter for SAP Exchange Infrastructure supports additional administration queues, in which application dependent processing events are kept. Example 10-7 on page 611 gives an overview of these queues. Note that all the queues whose names start with SAPXIConnector are optional for the implementation of this scenario.

From the perspective of SAP Exchange Infrastructure, WebSphere Interchange Server is the source back-end system from which it receives XML messages using JMS. R/3 is the destination back-end system where IDocs generated from the XML messages are submitted using the SAP Exchange Infrastructure IDoc adapter (Figure 10-76). Figure 10-76 Overview: SAP XI processing for CustomerDataRepository 10.5.1, “Overview of SAP XI configuration” on page 612 starts with an overview of the general components to be configured for SAP Exchange Infrastructure. Then the description of the configuration itself follows. It is assumed that a completely installed and, for general processing, configured SAP Exchange Infrastructure system is up and running node itso_xi. The following part of this section covers the preparation of the R/3 back-end system. This section ends with showing how to test the configured SAP Exchange Infrastructure together with the WebSphere Business Integration adapter for SAP Exchange Infrastructure.

- 654. 612 WebSphere Business Integration for SAP 10.5.1 Overview of SAP XI configuration Look at Figure 10-77 to get an overview of the major components of SAP Exchange Infrastructure: The Integration Repository provides the environment for the development of integration scenarios, including business processes and mappings of interfaces. By use of the Integration Directory, the different objects of an integration scenario are configured. The Integration Server is the central run-time component, hosting the integration engine, which is responsible for receiving, processing, and forwarding messages, and the central adapter engine that is used to connect external systems. All systems involved in a integration application are registered in the System Landscape Directory (SLD). Figure 10-77 General components of SAP XI The operational model shown in Figure 10-4 on page 558 assumes that these components run within a SAP Web Application Server V6.40 for ABAP and J2EE systems on node itso_xi. The main configuration task for Use Case CustomerDataRepository is done using the Integration Directory and the System Landscape Directory. The entities to be configured there are summarized in Figure 10-78 on page 613. Design Configuration Runtime Integration Server Integration Repository Integration Directory System Landscape Directory
- 655. Chapter 10. Use Case 4: Integration of SAP XI with WBI InterChange Server 613 Figure 10-78 Entities to be configured within the Integration Directory Since the WebSphere InterChange Server is responsible for generating XML messages, which are compatible with the IDoc-XML-format, no further mapping processing needs to be done within SAP Exchange Infrastructure. This is the reason why the Integration Repository is only required for importing the IDoc type DEBMAS01 to the WebSphere InterChange Server, but not for specifying the integration scenario. The two back-end systems (from the perspective of SAP Exchange Infrastructure, SAP R/3 and WebSphere Interchange Server) are registered within the System Landscape Directory and configured as business systems within the Integration Directory. A business system that is a sender submits messages over an outbound interface to SAP Exchange Infrastructure. A business system as a receiver gets messages from an inbound interface from SAP Exchange Infrastructure. Note: This is for simplicity reasons. In a real integration project, it is recommended to build the integration scenario in the repository first.

- 656. 614 WebSphere Business Integration for SAP Communication channels define the possible physical bindings for the communication of the Integration Server with the business systems or other services. A communication channel has either a sender or receiver direction. On its way from a sender to a receiver, a message traverses different processing steps that are defined by the configuration objects listed below: 1. The sender agreement specifies the protocol conversions that must be done on a message so that it can be processed by the Integration Server. 2. The receiver determination defines one or more receivers for a given sender. Routing conditions can be specified that determine the receiver based on the message content. 3. The interface determination specifies a sender and a receiver whose inbound interface is to be used at the receiving side. 4. Finally, the receiver agreement determines the protocol conversions that must be done on a message that flows between the Integration Server and the receiver. The next paragraphs describe how to configure the entities named in Table 10-7 for the implementation of Use Case CustomerDataRepository. Table 10-7 Named entities within the SAP XI configuration 10.5.2 Register back-end systems in System Landscape Directory Within Table 10-7, MasterDataEntrySystem represents the WebSphere InterChange Server and EnterpriseCore the SAP R/3 where the customer data get stored.

Restart SAP Exchange Infrastructure in order to make these changes effective. 10.5.7 Test configured SAP XI together with WBI adapter for SAP XI One approach for testing the configuration described in this section is to put an XML message, which conforms to a DEBMAS01 IDoc structure, into the queue WBI_XI_Queue and check that it is delivered correctly to the SAP R/3 system. As a producer of the XML message, the adapter for SAP Exchange Infrastructure is used together with the Visual Test Connector (VTC). In this way, the configurations described in 10.4, “Configure the adapter for SAP XI” on page 598 are tested as well. The test follows the same approach as in 10.3.4, “Test the configured connector for Lotus Domino” on page 586, except that in this case the VTC together with the port connector is used as a sender of Customer business objects. Figure 10-110 shows the combined test scenario. Figure 10-110 Test configured SAP XI together with WBI adapter for SAP XI Prepare the test The mere requirement for testing the configured connector is to create a special collaboration object from the template CollaborationFoundation, whose From port is bound to the PortConnector and whose To port is bound to the SAPXIConnector. After deploying the updated user project, the test scenario is ready to be executed: 1. Open the library CustomerDataLib within the system manager, navigate to the folder Collaboration Objects, and select Create New Collaboration Objects... from its context menu (Figure 10-40 on page 588). 2. Within the Create New Collaboration window, highlight the CollaborationFoundation template and enter PortConnector2SAPXICollaboration as the collaboration object name. 3. In the Bind Ports window, bind the From port to the PortConnector, the To port to the SAPXIConnector, and the DestinationAppRetrievPort to the PortConnector. After pressing the Finish button, the collaboration object is created. Figure 10-111 on page 635 shows its “tree view”.

Save the XML schema of the IDoc type by selecting Tools → Export XSD... from the menu (see Figure 10-123). Figure 10-123 Export DEBMAS01 as XSD file 10.6 Run the scenario CustomerDataRepository The test scenario described in 10.5.7, “Test configured SAP XI together with WBI adapter for SAP XI” on page 634 paves the way for running the overall scenario CustomerDataRepository. The only change is to replace the PortConnector in Figure 10-110 on page 634 with the connector for Lotus Domino in order to get the environment for running the overall scenario. As a consequence, the connector for Lotus Domino must be linked with the connector for SAP Exchange Infrastructure by defining a collaboration object Domino2SAPXICollaboration whose From port is associated with the DominoConnector and whose To port is bound to the SAPXIConnector. To define and deploy this collaboration object, follow the description for PortConnector2SAPXICollaboration in 10.5.7, “Test configured SAP XI together with WBI adapter for SAP XI” on page 634. The tree view of the resulted collaboration object is shown in Figure 10-124 on page 642.
- 684. 642 WebSphere Business Integration for SAP Figure 10-124 Collaboration object Domino2SAPXICollaboration Before running the scenario, ensure that the major systems Lotus Domino Server, WebSphere InterChange Server, SAP Exchange Infrastructure, and SAP R/3 are up and running. Then start the connector for Lotus Domino (see “Execute the actual test scenario” on page 593), and the connector for SAP Exchange Infrastructure (see “Run the test” on page 635). Start the scenario by creating a document in the Lotus Domino database called Customer Contacts (Figure 10-55 on page 596). After that, check the intermediate steps as shown in Figure 10-56 on page 596 and in the test description in 10.5.7, “Test configured SAP XI together with WBI adapter for SAP XI” on page 634. Finally, verify that a corresponding IDoc is received within the SAP R/3 back-end system (Figure 10-119 on page 639). 10.7 Summary This chapter describes the implementation of a Use Case that integrates the two back-end systems Lotus Domino and SAP R/3 using the two integration brokers, WebSphere InterChange Server and SAP Exchange Infrastructure, in between. The key capability of this implementation is to demonstrate how an integration broker itself can participate as an enterprise information system in an overall business integration scenario. The implementation uses JMS over WebSphere MQ for a broker-to-broker communication. It makes extensive use of InterChange Server mapping technology to transform generic Domino Documents, received by the WebSphere Business Integration adapter for Lotus Domino, into business objects that are compatible with a given SAP IDoc structure.

- 686. 644 WebSphere Business Integration for SAP 11.1 General hints and tips Make sure you have installed the proper SAP Java Connector version. start_SAP.bat refers to two jar files named jco.jar and sapjco.jar, but only the reference to sapjco.jar is required. jco.jar is the name for older JCo versions. jco.jar does not exist and is not required. A Class Not Found Exception will be thrown if you leave it in the start_SAP.bat. Use the latest WebSphere Business Integration Adapter for mySAP.com version. 11.2 Use Case 1 Make sure all necessary WebSphere MQ queues are implemented before starting the WebSphere Business Integration Adapter for mySAP.com, especially the Unsubscribe and Error queues. When configuring the Business Workflow in SAP R/3 V4.7 for the ABAP Extension Module, there are two transactions and tables that must be configured (Instance Linkages and Event Type Linkages). In SAP V4.6c, it is only one table (Event Type Linkages). The Event Distribution tables in SAP R/3 are case sensitive. If the case does not match, then events do not get picked up by the WebSphere Business Integration Adapter for mySAP.com. 11.3 Use Case 2 Do not install the Embedded Messaging feature of the WebSphere Business Integration Server Foundation if you plan to use a WebSphere Business Integration Adapter that communicates via JMS with the integration broker. Instead, install a full WebSphere MQ Server as the Messaging provider. Use prefixes in the WebSphere MQ queue name to be able to identify to which adapter a respective MQ queue belongs. The SAP Object Discovery Agent (ODA) uses different startup batch files than the SAP Connector for startup and execution environment configuration. Adjustments like SAP Java Connector (JCo) updates have to be made in both environments. Use exactly the same SAP JCo version for the SAP ODA and the SAP Connector.
- 687. Chapter 11. Best practices and lessons learned 645 Verify that the RFC server specific business object handlers are located in the bapiserver folder of the SAP Connector. Review SAP Connector properties in test and production environments. The default values may not be adequate for your needs. Use the Visual Test Connector to replace the target back-end system and verify the correct adapter-broker communication. Be aware that the Visual Test Connector can only simulate a back end to the integration broker and not vice versa. Be aware that the Visual Test Connector cannot simulate a back end outright. Usually, integration scenarios that ran successfully with the test connector have a malfunction when the real back end is connected. Use the Universal Test Client within WebSphere Studio Application Developer Integration Edition (WSADIE) to test generated deploy code. This can be done on the activity level and on the process level if an EJB binding has been chosen. Avoid long names for generated business objects, because this name is used to generate unique class and package names in WSADIE. In some circumstances, this can exceed command-line limitations on Windows platforms when deploying the generated EJBs. Refer to Microsoft Knowledge Base Article - 830473 for further details, which can be found at: http://support.microsoft.com/default.aspx?scid=kb;en-us;830473 11.4 Use Case 3 Ensure that the db2jcc.jar and the db2jcc_license_cu.jar are on the system path or on the JCLASSES entry in all of your batch files that start your adapters and WebSphere InterChange Server. It is important that you do not choose to have the collaboration template require a transaction when doing a query. The reason behind this is that a retrieve request creates a new business object on the return trip. A transaction scope does not allow you to change the business object to return a new one instead. If you require a transaction, then the new business object is discarded and the original gets return. If you do not require a transaction, the new business object is returned in place of the original.
- 688. 646 WebSphere Business Integration for SAP 11.5 Use Case 4 Shut down and restart the InterChange Server after each new deployment. Ensure that after a restart each deployed component is started. Do not forget to start the PersistentNameServer before starting the InterChange Server. Do a unit test using the Visual Test Connector after each major configuration step. Clear all unprocessed entries within the Lotus Event Table before starting a new test scenario.

Experts from IBM, Customers and Partners from around the world create timely technical information based on realistic scenarios. Specific recommendations are provided to help you implement IT solutions more effectively in your environment. For more information: ibm.com/redbooks WebSphere Business Integration for SAP WebSphere and SAP integration using WBI Adapters Business connectivity using WBI brokers WBI and SAP XI interoperability scenario The need to integrate heterogeneous environments without replacing existing IT infrastructures is growing more and more. Standard application providers offer a wide range of business applications, running on different platforms, and implemented in different languages. A sophisticated Enterprise Service Architecture is required to overcome the challenges implied by such a heterogeneous infrastructure and make the whole enterprise controllable. The WebSphere Business Integration architecture provides different Integration brokers and a multitude of application and technology adapters. It is an essential software component in IBM's e-business on demand strategy. SAP Exchange Infrastructure is SAP’s strategic technology platform for process integration and connectivity of SAP components and non-SAP components. This IBM Redbook illustrates how to integrate data and processes located in SAP back-end systems using WebSphere Business Integration middleware technology. It describes two WebSphere Business Integration adapters: IBM WebSphere Business Integration Adapter for SAP V5.5.0 IBM WebSphere Business Integration Adapter for SAP Exchange Infrastructure V1.0 These adapters are utilized to demonstrate the integration capabilities they provide.
