If you are running multiple app servers and kicked off your job in the background, chances are that if you go to SM50 to look for it, you won't see it because it is running on another server. You could go to SM51 and drill into each app server and look. But, this gets tedious. Someone once showed me SM66 and I've never used anything else since. This transaction shows all active sessions across all servers. I haven't seen it under any menus, so I thought I'd pass it on.
