Summary :
When attempting to post documents involving materials with a moving average price valuation, the error M8783 is triggered if the resulting moving average price becomes negative. This occurs primarily due to discrepancies in inventory levels or pricing variances during invoice postings. The SAP system is designed to prevent postings that would lead to such scenarios, instead rejecting transactions unless the error message is appropriately addressed as per the guidelines available in the SAP documentation. Automatic postings to price difference accounts are not performed in these instances to prevent erroneous stock value representations.
