Inactivating some user temporary with fnd_user_pkg.disableuser

Hi,

I'm going in production with maintenance. I need to disable some user account and let some user go in.

I wanted to user fnd_user_pkg.disableuser. It's seem to work well in test.

I wanted to ask if some of you already use this function in production for same raison and did you have some problem?
