Checking Analysis Authorizations as Another User 

In the administration for analysis authorizations you can execute certain transactions as another user by choosing the function Execute as... on the Analysis tab page. All the checks for analysis authorizations (only) are then run for the defined user.  It is possible, therefore, that a user could gain access to more authorizations than he or she would normally have. For this reason, this transaction should be protected using the authorization object S_RSEC.
