In some real time scenarios, if there is an emergency like, a  change to a table to be done but particular end user doesnot have access to change the tables.  Then they may approach basis administrator/security(authorization) consultant to identify those users who are having that access so that they can request them to change the same in case of emergencies. So, you should be able to identify those users and confirm to business users.

In general, basis/authorization consultant should be able to identify all user ids who are having access to a particular tcode. This can be done in the following way.

In this example, am demonstrating how to identify all the users who are having access to SE16 in a given SAP system.

Once you input transaction code, click on highlighted clock button, which results in the following screen which displays the list of users who are having access for SE16 in this SAP system.
