Shirin,
The issue is I can't create qualification groups directly in the transaction OOQA due to this authorization error, however, it is not an actually security issue because I am a user with SAP_ALL.
A workaround is creating qualification groups in PP01, and then I can create qualifications in OOQA, but still not qualification groups.
This is an issue only in one of our clients - the rest this is not an issue,.
