All I do is a stock transfer from one location to the other in IC to clear out my negitives. I'm not sure if that's the answer you're looking for but that's how I've always cleared them out.

What probably should be done is although the PO has to have the location shown on the header (pg 1) as where the PO orginated the buyer should key in the location as the alternate location on the detailed section for each item if not being rec'd at the orginators location. You maybe also able to edit each items location when receiving the goods.
