Summary :
When attempting to post an invoice for a purchase order in SAP, error M8783 may occur, indicating a negative moving average price for the material. This error typically arises after a valuated goods receipt is posted and the invoice, showing a price variance for goods received, is subsequently posted. If additional valuation-relevant transactions affect the material's value between these events, it can lead to a negative total material value. To resolve this, users must increase the stock value via transactions MR22 or adjust the invoice item amount in MIRO before posting the invoice. Proper simulation and correction in invoice verification are crucial to prevent material value discrepancies.
