Hi Praveen
Have you verified if the person assigned to the user moved positions? Alternatively, a change to their 0105 mapping Have a look at their PA20 record for organisational assignments to see if they are in a different position.You should see a history of the user's org assignments with date delimits
If the user is still in the same position and access was deleted from the position, you might see who last made a change in PP01 or you might need to run a report to see who has the PLOG access for Infotype 1001 with AG (Role). If you HRP1001 table logged you can run report RHCDOC_DISPLAY
