Prerequisites 

The data created during role maintenance must exist in the role allocation system before you can assign the roles. The data might not yet exist in this system for one of the following reasons:

Make sure the data is imported

The initial screen of Transaction WP3R contains the Read roles from client systems pushbutton. This function can only be performed correctly if all client systems can be reached synchronously.

All the users who are to be assigned roles must first have been copied to the central user administration. If you activate central user administration or add new systems, you must first close the copy process before assigning the portal roles.

Check the copy process with Transaction SCUG: None of the systems may have status New.
