I have a Purchased Part with Inventory Valuation Method set to Weighted Average (WA). It is also a Sales Part and the Company is set to Delay Cost of Good Sold to Delivery Confirmation.

There is an existing quantity for this part with WA let’s say equal to 100 unit cost. I have created a customer order, reserved then delivered it. This created an inventory transaction history DELCONF-OU and DELCONF-IN with unit cost of 100. Before I execute a delivery confirmation, I created a new Purchase Order and changed the price to something that would change the WA. Received it into stock. WA has changed to for example 150 unit cost.

Executed the CO Delivery Confirmation and it created a transaction DELIVCONF with unit cost 150. If I look at the overall postings for the CO, it is causing my GL Balance to have a balance for account in M1 posting type. Is this correct? Has anyone encountered the same problem?
