We use SAP byDesign.
I generated a purchase order for 600 widgets.
The vendor sent us 603 widgets but only billed us for 600.
The receiving department received in 603 widgets.
We applied the invoice for the 600 widgets to the receipt and changed the quantity received from 603 to 600. This left 3 widgets to be billed.
We got the invoice from the vendor for the extra 3 widgets, but SAP byDesign won't let us apply the invoice to the receipt because it says the purchase order was only for 600. That shouldn't matter since we did receive in 603 and not all of the receipt has been invoiced.
SAP by Design won't let me re-open the purchase order to add an additional 3 widgets. If I generate another purchase order for 3 widgets and receive it in then I have 6 widgets waiting in Invoice Entry for an invoice.
How do I fix this? I've got an invoice for 3 widgets I need to process.
