Expense Distribution added to PO changed to expense account on the Inventory when the item was recei

Our accounting folks have noticed that the Accounting Distribution on the Purchase Order Changes to the Accounting Distribution on the Inventory organization when it is received. They want the accounting to remain the same as that entered on the PO. Is there any setup change we could make to cause this to happen. I can't think of anything out of the box that would do this? Any help would be appreciated.
