Hi Kjell
Then, how to get back the original standard roles as they are going to implement a new authorization concept.
Do you really need the SAP standard roles? Most times they are there for reference. You need to get Basis to look at client 000 to check if they are there. If there are use PFCG mass download and upload them to client 100.
If they aren't in 000 either (would be strange) then you might have to reach out to SAP for assistance via Marketplace.
