You have configured Central User Admin (CUA) for your SAP User maintenance. And you want to delete inactive system from CUA Configuration.
You access the config from transaction code SCUA -> Distribution Model -> Change
System connected to CUA.
But when you tried to delete it you get an error “Cannot delete: Target System <LogSystem> is part of an active CUA“, as shown below.
To solve this problem you can delete the inactive system using program RSDELCUA.
Fill with the logical system you want to delete. Click “Test” to see the affected table entries.
Run execute to see the result.
Now you can go back to the initial screen RSDELCUA, and untick “Test” for deletion. And run execute.
This time you will see the result of deletion.
Now you can check again from transaction SCUA. You have successfully delete the inactive system from CUA configuration.
