AP Reserve invoice with GRPO Less Quantity

Dear Experts,

Is it possible to close a reserve invoice which has been fully paid but not fully delivered ?

Here is the process i would like to have :

- Edit AP Reserve Invoice of 100pcs

- Pay the AP Reserve Invoice (100% of reserve invoice amount)

- Goods Receipt PO of 80pcs

- Close the AP Reserve Invoice (to record the impact on the stock - paid 100pcs, but in stock only 80) => it seems impossible to close this document.

Indeed, I need to pay the full invoice, even if the receipt is less quantity than the reserve invoice (this has an impact on the moving average price of the stock).

My version is a 2007B SP00 PL10. Does anybody has any clue for this ?

Thanks in advance for your help and advice.
