After you have synchronized the company addresses, you can transfer theusers from the newly connected child systems to central administration.

transaction SCUG in the central system. To do this, on the initial screen of
transaction SCUG, select your child system and choose the Copy Users to the Central System button.

You can use the report RSCCUSND from the central system of Central User Administration (CUA) to synchronize the master data of selected users with a child system of the CUA. The report sends the master data (including role and profile assignments) to a child system of the CUA.

If master data exists in the child system for the user sent, it is overwritten.
Procedure…
1. Start report RSCCUSND (for example, using transaction SA38).
2. In the Receiving System field, specify the child system to which you want to send the user data.
3. You can use the fields User and User Group to restrict the number of users.
4. Specify the data that you want to distribute under Distribution Options.
5. Choose Execute.
