In receiving goods, occasionally there is one invoice for the items themselves, (paid to the vendor), and another invoice for the cost of shipping, (paid to the shipper). For the former invoice, all the items are invoiced, and in invoicing the PO, none of the items, (as I would think), would be invoiced since they were already invoiced in the vendor's invoice. However, when this is done, the costs of shipping aren't distributed to the items, since none of the items were selected as being invoiced in receiving the shipper's invoice. 

My question is how to receive invoices connected with a PO without having to invoice the items, i.e., without having to enter the number of items invoiced as being invoiced in receiving the vendor's invoice.
