I have a Raw Material, which is having Price Indicator as V and the Price Determination is 2. I have raised a PO for 100 Units at 1.50 USD per Unit. GR is done for 100 units. At the time of IR, the Value of Invoice is 200 USD.
Since, there is enough stock coverage, the variance should be adjusted to Inventory Value (Material Price). However, at the time of FI Document posting the difference of 50 USD is going to Price Variance Account (DIF in OBYC) is getting triggered.
All SAP Notes speak of Stock Coverage, however, i have enough stock coverage.
When the invoice are being posted, are you changing the amount inside the items or only modifying the amount in invoice header?
If you only modify the header amount, the system will trigger the account regarding the price difference, however, when you also modify the item material amount the inventory is updated with the new value.
By the way, check yours constrains regarding price difference, on t-code OMR6 tolerance key PP, it must be more than 25% in percentage or greater than $ 50 USD. generally this values are lower.
