A receipt changes quantity.
It can also change value.
Separate Quantity From Cost
Was the wrong quantity received? Was the cost wrong? Did both happen?
Check the Item, Warehouse, and Cost Method
Sage supports standard, average, FIFO, LIFO, lot, and serial costing by warehouse. The applicable method matters when tracing the valuation impact of a receipt.
Follow the Receipt History
The item value is built by transactions, not by the inventory inquiry screen itself. Trace the receipt that introduced the unexpected quantity or cost.
