I'm not sure what your exact requirements are but they are other options:
- If you start PFCG and then go to menu Environment -> Display Changes, you can display changes to roles. For example you have the option to select only 'User Assignments' to display changes in user assigments. You have also various selection options such as selecting the roles, the start/end dates of the changes or a selection of users.
- You can download tables, using SE16/SE16N/SE17. Save them as text file, import in a speadsheet / database and use that for reports. Most important tables are: USR02 (The user master Data), AGR_USERS (Assignment of roles to users, together with information of who did the assignment and when). Other tables that can be used is : ADRP (contains address data, such as last name, firstname), and USR21 (to link the user ID of the USR02 to the address ID /pers. ID used in ADRP)
I hope this helps
