This document provides an overview of connecting SAP Business One with third party applications using the Service Layer. The webinar agenda includes an introduction to the Service Layer, its architectural differences compared to other communication channels, when to use it, demonstrations of connecting to SAP Business One and retrieving objects using HTTP tools and a .NET client, and references for more information. The Service Layer exposes SAP Business One data and objects to external systems using standard OData formats for improved integration, scalability and portability.

- 4. Overview
- 5. • Service Layer is an extension to SAP Business One to expose data and objects of SAP to external world. • Service Layer is built as a Web Component following HTTP protocol, more specifically Odata. • Open data standard enables SAP Business One objects to be consumed using basic HTTP methods and also opens wide range of tools to consume data. • Service Layer runs on SUSE Linux Enterprise Release 11 SP2, 64-bit edition. It is an application server built on the Apache HTTP Web server. The required database backend is SAP HANA Platform Edition 1.0 SPS 07 Rev74 Service Layer
- 7. • Service layer is the code component to communicate with SAP Business One. • It is built using standard ODATA formats. • It directly communicates with SAP Business One Core, and hence best when throughput is concern. • Service Layer is built keeping data integration in mind. • Service Layer supports WCF Restful services and hence can be consumed with WCF tools • Many 3rd party libraries are built on top of SL to build communication channel with SAP Business One. Features
- 8. • Service Layer has a 3-tier architecture: the clients communicate with the Web server using HTTP/OData, and the Web server relies on the database for data persistence. • Service Layer API and DI API have identical definitions for objects and object properties, smoothing the learning curve for developers who have already acquired DI API development experience. • The OData Parser looks at the requested URL and HTTP methods (GET/POST/PATCH/DELETE), translates them into the business objects, and calls each object's respective method create(Add) /retrieve(GetByKey) /update (Update) /delete(Delete) (CRUD) operations. In reverse, the OData Parser also receives the returned data from business objects, translates them into HTTP return code and JSON data representatives, and responds to the original client. • The session manager implements session stickiness, working with the Service Layer load balancer, so that requests from the same client will be handled by the same Service Layer node.

- 13. • When you cannot use COM interfaces of DI Server component. • When your application need to have scalability and portability. • Outside your home network. • Require HTTP standards while communication • Need to use your existing toolsets for communication • Less learning curve • Uniform way of representing structured data : ATOM, JSON • Enhanced documentation When do you use Service Layer?
