How to correct cost on a “Return from Projects” SO?

Hi all,

We have an SO type RP (Return from Projects) that should only increase quantity and have zero cost. However, one SO (completed 1 year ago) was posted with inventory cost by mistake.

Our items use the Average Cost method and are still in stock.

What is the safest way to fix the wrong cost impact from this SO without affecting inventory valuation or accounting incorrectly?

Thank you!

Hi ​@kimhungnguyenthi 

The safest approach is not to modify the original SO or shipment. Since the item uses Average Cost and is still in stock, the correct fix is to post a cost-only Inventory Adjustment to reverse the incorrect cost impact. This preserves audit history while correcting inventory valuation.
Note that when performing Inventory Adjustments, you should use the Reason Code with the appropriate adjustment account.
