Record a Price Correction. Use a price correction when a supplier sends an invoice for a change in unit price for an invoice you have matched to a purchase order. You can record a price correction by checking Price Correction when you match a credit/debit memo to a purchase order shipment or purchase order matched invoice distribution. When you record a price correction for a credit/debit memo, you are recording a price decrease from the original invoice.
Payables updates the invoiced unit price of previously matched purchase order shipment or distributions without adjusting the quantity billed so you can track price variances; Payables also updates the amount billed on the originally matched purchase order distributions
