simple warehousing

Hello, We’re using NAV 2009R2 6.0 Classic. We need to do a simple warehousing on a one location that would be ONLY a current qty available, receiving Items in, and sending it out, knowing a UserID who did it. The locations from where it would be received and where it would be send don’t matter. So, it would be a “fake” unlimited FROM warehouse. We’d only need to record a reason for sending items out. Please, advise what Forms and Documents we would need to do it. Thanks
