Editor's Notes
- #4: A client is a logical portion of an SAP R/3 physical database. From a business standpoint, a client can be interpreted as a logical group of companies. All customizing (configuration) and development (ABAP) work in SAP R/3 is performed in aclient. However, the data from both customizing and development work may be stored within an individual client (client dependent data) or among all clients (client independent data) in the system.
- #5: The data in each client may be separate from that of the other clients. There are basicallytwo types of data in an SAP R/3 System. Client-dependent and client-independent data. Client-dependent data is defined as data specific to an individual client. Client-independent data can be defined as data contained across all clients in the system. Some examples of client-dependent data include number ranges, ABAP variants, and user masters as well as the data that is created or updated through SAP R/3 transactions transaction data). Examples of client-independent data include data dictionary objects (tables, views), ABAPsource code, screens, and menus. All data resides in tables. To determine if a particular table is client-dependent or client-independent, the table structure needs to be reviewed. The table structure can be viewed by the data dictionary (SE11). If MANDT (client in German) is the first key field of the table, then the table is client-dependent; otherwise, the table is client-independent. For example, the TSTC table is client-independent; however, the USR01 table is client-dependent. As shown in the above diagram, every SAP R/3 system contains the three clients 000, 001, and 066. Let’s review these clients and examine what they contain.
- #8: During a standard install of the SAP R/3 system, clients 000, 001, and 066 are set-up andprovided. These clients provide different features and must not be deleted. Client 000 performs special functions. In particular, it is given extended functionality during upgrades. Client 001 is basically a copy of 000 and can be used as a basis for a new customizing client. Client 066 is a special client which is provided for operational system monitoring. It is used by SAP R/3’s Early Watch Service to provide performance recommendations.In releases prior to 3.0, client 000 contained a model company. As of Release 4.0 clients, 000 and 001 are identical. Client 000 no longer contains a model company. Either client can be used as the basis for configuration through a client copy. Typically, most projects start with a copy of client 000 to begin building configuration.Customer work should never take place in the three delivered clients.
