I think this is the way we are probably going to have to do this. The reason to "unreceive" the 5 from the PO is to show that the PO is still open (good widget qty not fulfilled yet).
We have a person who "receives items". If there is a return (even though we are getting replacement items) the PO shows closed and there is nothing to receive. If there is no way to do this, then we will just go the route you said, but it would be nice to have the PO remain open until we get all of the items.
