Choose Administration → System Administration ® Administration → Client Administration → Client Maintenance, from the SAP main menu.
For more information on maintaining clients, refer to the F1 help documentation.
If you have maintained a logical system in each of the source and target clients and assigned it to the client, the logical system names in the target client application data are automatically converted after copying the application data (e.g. with copy profile SAP_ALL).
For further details, see Application Server → IDoc Interface/Application Link Enabling (ALE) → Basic Settings → Set-Up Logical Systems in the IMG.
