Hi Ask,
Yes, you can use RSUSR100N progaram(Use SA38 to Run) or SUIM change documents for users to get user lock details.
RSUSR100N program gives list of user by Administrator lock and incorrect logon locks with interval of time(i.e From date and To date).
So you can get list of users before activity date and after activity date with lock status.
conclusion: By getting report you can keep lock all the user who are locked before actvity, rest of the users you can unlock.
use bellow to know lock status!!
0- Not Locked
32- Locked Globally By Administrator
64- Locked Locally By Administrator
128- Locked Due To Incorrect Logons
Thanks & Regards,
