In SAP, BW master data IDs and dimension IDs are made up from number ranges. BW objects are client-independent and can be accessed and changed in all clients in the same way. However, as number range intervals are client-dependent and IDs have to be unique, IDs can only be determined within one client. This client is called the BW standard client.
