The client is locked for data import by client copy
I need to refresh my Quality system with all the Productive data, so I made a client export on my PRD system.
When trying to import the generated requests to my QUA system, SAP gives me this error message: "The client is locked for data import by client copy".
However, when checking SCC4 on QUA, I can see that it has any restriction at all ("Protection level 0: No restriction"). The target client role is set to "Test" and every change is allowed in it.
I don't know what to do or why the client import is not being allowed. Can you help me?
