Epicor905 702 Purchase Order Receipts

Hello,

Our users have reported that they never have allowed to receive a product in a plant if the PO release set to another plant. When I checked myself, I find out that system gave us a warning message " This PO release does not belong to this Plant", when I pressed ok system allowing us to received the product in the wrong plant, which is messing up our stock, because users overlooked the warning sign sometimes. It looks like we are missing a BPM directive, for some reason.
Can someone share the BPM directive and condition, that I can put in again, so that user can only receive the stock if the stock belong to that specific plant. Or if there is any other way to that stop the receipt if the PO does not belongs to that plant ?

thank you
