Dear AJ,
do the manager work in access requests properly? There is a general problem with manager picking from UAR as it uses a different program than access requests. If in ARQ the manager gets picked correctly this might be the issue. I will keep you updated when SAP releases the OSS note.
If the manager isn't correct in ARQ either, you have to check basic information for these users. E.g. info type 0105 (subtype 0001 for SAP user, subtype 0040 for user id) as the user ID must be mapped with a person in organizational management.
Let me know and I will provide you with further information.
Best regards,
Alessandro
