FA is using the average material cost when calculating the cost prices.
The item cost price can be manuelly adjusted in the Items and Inventory tab. These Changes will not affect the stock movements and therefore will show the wrong results when using the stock movement cost prices.
This is the fact for report:
Inventory Valuation report,
The reports, Inventory Sales Report, GRN Valuation report, Inventory Purchasing report, Costed Inventory Movements, Inventory Sales report shows the correct cost price values for the stock movements.
