CUA expire inactive users after period of inactivity

Hi All,

I've read a few postings, this one in particular Auto Lock the User not logged on for specific period but have yet to find a solution.

We use CUA (Central User Administration), is there a way of expiring users after say 3 months of inactivity without user intervention as a batch job?

This program would have to produce IDocs to send to the client systems.

We can use parameter login/password_max_idle_productive but this only locks the users, we need to expire them as well!

Thanks

Craig
