TCODE to check the list of active and inactive users in SAP in a single shot.
There are few customizing Tcodes, but most of us want to know if there is any standard Tcodes to list all the users in SAP.
T-Code AL08 & SM04.
If you are looking for a single TCODE where we can see list of total users(active & inactive) in a single shot.Is theer anything as such? SUIM will be the best option, and also i would suggest you to try Report RSUSR006 which lists locked users, the last login date, and whether users have ever logged in (and changed their passwords).
If you want to know all locked user in system then you can use transaction S_BCE_68001402
