Analyze Authorization check    SU53

1. Choose the menu path System -> Utilities -> Display Authorization Check or transaction code SU53. You now can analyze an error in your system that just occurred because of a missing authorization.
2. You can call Transaction SU53 in all sessions, not just in the session in which the error occurred. Authorization errors in other users' sessions, however, cannot be analyzed from your own session.
3. In the below example, user Bob calls Transaction VA03  (display sales order). The message "You do not have authorization for Transaction  VA03" appears. User Bob now chooses transaction code /nSU53 and the system displays the authorization object that was just checked and, for comparison purposes, the values of the object that user Bob has in its user master record. In this case the user Bob don’t have VA03 assigned to any of his role.
4. Transaction SU56 allows the user to see what current authorizations are in his buffer
