Setting Up Logical Systems
Systems of the Central User Administration (CUA) are referred to using logical system IDs. In the SAP sense, a logical system is a client. Therefore you must first set up logical system names that you then assign to the clients in the SAP systems.
It is possible that the logical system name already exists because you have already included the system in an ALE distribution. You can then ignore the procedures Define/Set Up Logical System and Assign Logical System to a Client.
This maintenance is cross-client; that is, you only perform it once for each SAP system. If your logical systems are clients of the same SAP system, you only need to perform this step once.
