Change a client In SAP




      When adding a new client to a SAP system, the information listed in
      the SCC4 can be confusing.  This is a brief explain of the
available client restrictions.

      Client role:

            The category indicates the role of the client in your R/3
            system.

     Possible roles are:

            *     Production client
            *     Test client
            *     Training client
            *     Demo client
            *     Customizing client
            *     SAP reference client

            This field should be maintained by the customer for
Documentary purposes. Release 3.0 also ensures the following:

If there is a productive client in the target system, no client copy (remote copy) which also selects cross-client customizing objects may be imported into the system. If cross-client settings are imported, inconsistencies may occur in all clients.

In a productive client, customizing settings that can be maintained as "current settings" can be excluded from a client lock or transport links; this means current settings (e.g. exchange rates, posting periods) can always be maintained in a productive client without recording changes. SAP is planning to link further effective functionality to this flag, to enable adequate protection of a productive client in a system with further (test) clients.

     
Other settings for a client:

            Change and transports for Client Dependent Objects
                 
Changes without automatic recording – the client can be customized although the system will not generate change requests.
           
Automatic recoding of changes – the client can be customized and all changes are generated into change requests.

No changes allowed – no modifications can be made to the client – it is protected or locked.  This is the usual configuration for a production client where customization should not be performed.

                  No transports allowed – changes are allowed but cannot be
                  transported.

            Client-Independent Object Changes

Changes to repository and client-independent customizing allowed – no restrictions on this client for changes and development.

No changes to client-independent customizing objects - allows for development on repository objects but not client-independent customizing.

No changes to repository objects – lets users perform client-independent customizing but no development or modifications to repository objects.

No changes to repository and client-independent customizing objects – this setting prohibits any client-independent modifications and is common on Production systems.
