SAP ERP 查最後一次登入
you can look in table USR02, ther one filed TRDAT is the last logon date
(with tx se16 for ex)
or you can run report RSUSR200 (with TX se38)
but with this reports you will see only which users was or was not in the
system. you can not see if they have had low activity, or statistics like
this
