For each goods receipt PO line, a price is calculated that is equal to the item’s 3PL inbound price (which can be set up on the Produmex tab of the item master data) multiplied by the received quantity (in inventory UoM). The inbound item quantity price is the total of all these prices for ¬all goods receipt PO’s in the invoicing period.
On the 3PL invoice, the quantity for that item is always 1, and the total price is set as unit price.
