The Price in the Expenditure part is the price of the goods being processed. The price is calculated using the FIFO method.
The Price in the Receipt part is the price of the goods received after processing. The price of received goods depends on the quantity of the original goods in this line, i.e., when the goods quantity in the Expenditure part increases, the self-cost of received goods increases as well.
If the goods quantity in the Expenditure part matches the goods quantity in the Receipt part, the price of the goods being spent will be assigned to the received goods, even if these goods had a different price
