Slightly complex one this, albeit it should be something that AX can handle.
We raised a purchase order for two items from a vendor. Say Item A for £100 and Item B for £200. Both items arrive and are booked in in the normal way using arrivals overview. The invoice then arrives, but is incorrect, showing Item A at £100 but item B at £250. Not withstanding that the invoice is incorrect, the invoice is still registered in the usual way and then posted against the purchase order, with the new price of £250 for item B. Note the purchase order isn't changed, just the "approve posting with matching discrepancies" box ticked. The items themselves are then used in the normal course of business (i.e maybe sold to customer, or used in project)
A while later a credit note comes from the vendor for £50. The credit note is registered but not yet posted
What is the correct way to post the credit note?
All the AX documentation we have found so far refers to a situation where the credit note was issued because of faulty or returned goods, or where the quantity delivered was incorrect. This is not the case here, we do not want to alter the physical quantities in any way. One item was ordered, and one arrived. We simply want the financials altered so that the vendors account shows an invoice for £350 and a credit note for £50 so that we can make a payment of £300 to the vendor and for the consumed cost of item B to be £200 not £250
