SAP CLIENT GLOSRY documentation, setup help and example usage

Client
Organizational unit of an AS ABAP . Every time users log on to an AS ABAP , they have to specify a client identifier , which enables them to log on to a specific client. The different clients of an AS ABAP have their own user master records with specific authorizations . Client-specific data is kept separate by means of the client column in application tables . Application programs are generally executed in application clients . There is also a system client
and in some cases multiple administration clients for carrying out system-specific or administration activities. On AS ABAP systems that support multitenancy , it is possible to map tenant s to clients.
