We use EDI to transmit POs to our suppliers. We are now enabling Consigned Inventory and would like to find out how we could separate Consigned POs from standard POs so the supplier doesn't bill us for the consigned items till the consumption advice is generated.
1) For consigned shipments, the consigned_flag in po_line_locations_all is set.
2) Supplier should not invoice consigned shipments. Even if he did, you won't be able to match the invoice to the Consignment shipments. AP Invoice screen will show up a warning as well. This happens because the Consignment shipment line is created in a "closed for invoicing" status and closes as soon as it is received.
