Client-Dependence of Database Tables

If the first column of a database table is a key field with the built-in type CLNT, the table is client-specific. In this case, the column contains the client ID evaluated in client copies and in implicit client handling in ABAP SQL.

Other versions: 7.31 | 7.40 | 7.54


  • Generally, tables in the delivery class A are client-specific, whereas system tables in the delivery classes E, S, and W are cross-client.

  • The system table T000, which contains the client IDs of an AS ABAP, is an exception. The first column has the type CLNT, but the table is cross-client. If the table is accessed using ABAP SQL, the additions USING and the obsolete CLIENT SPECIFIED cannot be specified.
