Users and Transport List for Audit Purpose

Hi everyone,

I have to generate a list of 'New users created' and 'TRs created' for a particular period and all active users list in the system. is there a report through whcih we can get this details from ECC 6? i checked SU01 ,SUIM, Rsusr200 report but could not find anything relevent to this requirement. can someone pleas assist me in getting these things done? not sure if we have to rely only on RSUSR200 then import in to excel then filter accordingly. These are required for the audit purpose.

please advise

Thanks,

Shiv
