Inter unit xfer vs. Inter company xfer with bu items

Wanted to know if anyone has run across an issue when dealing with intercompany bu item xfers where an item does not get picked up for replenishment. All items from one BU will not auto replenish, the job runs, but they don't get picked up by the process. Items from other BU's in the system are repenished whenever the min setting threshold is met but when these items are xfer'd it is treated as an inter unit xfer. When the items in question are xfer'd PeopleSoft treats it as a inter company xfer? Has anyone had issues around this? WE
