Description

This example program accesses two client-dependent CDS table functions.

• The CDS table function DEMO_CDS_GET_SCARR_SPFLI does not have any input parameters of the type CLNT. The implementation in the AMDP method GET_SCARR_SPFLI_FOR_CDS of the associated AMDP class CL_DEMO_AMDP_FUNCTIONS reads the data of all clients. Only the current client is selected here in SELECT statements.

• The CDS table function DEMO_CDS_GET_SCARR_SPFLI_INPCL has one input parameter CLNT of the type CLNT. The annotation @Environment.systemField is assigned to this parameter with the predefined value #CLIENT. The client ID of the current client is passed to this parameter implicitly in SELECT. The implementation in the AMDP method GET_SCARR_SPFLI_FOR_CDS of the associated AMDP class CL_DEMO_AMDP_FUNCTIONS_INPCL uses the input parameter to restrict the result set to the current client.

The result of the accesses performed without the addition CLIENT SPECIFIED is the same for both CDS table functions. If the obsolete addition CLIENT SPECIFIED is used to access the CDS table function without an input parameter for the client, the result set has an extra client column and the current client must be selected explicitly in the WHERE condition. The obsolete addition CLIENT SPECIFIED cannot be specified for the CDS table function with an input parameter for the client.
