Hi Guys

Now i find a strange problem in our production system.

**Material A is manage by MVP(Moving average price),but when warehouse do GR return by PO, and system will generate cost difference in FI Doc.

I know there are two cases will generate cost difference in MVP management

1. The MVP is change in T-code: MR21 before GR return

2. The stock is negative before GR return

I have checked in system,The material price doesn't change and also the stock isn't negative.I don't know why FI doc. will generate cost difference...

Detail information as below. Any expert know why? Movement type is 161

MVP cost 16 Currency USD PO price 12.84 PO quantity 1 PC After GR In FI Doc. Debit GR/IR Account 12.84 USD
Debit Cost difference 3.16 USD
Credit Inventory 16 USD
