Hi,

We are implementation the Supplier portal for our client. While Creating the ASBN from supplier portal, we don't have an option to see the unit price. we have only quantity and ordered quantity. Under the Billing information, we have a mandatory field called 'Invoice Amount' and use will have no idea which amount o mention here since they don't see the unit price at PO line level. there might be high chances of providing the Invoice amount incorrectly and will cause more work for AP team to correct the invoices.
