F&A Price not being recalculated at MIRO level.

Dear all,

I have a PO on which I have an F&A price.

At the PO creation I have a price which is calculated. This price is provisional.

Then I do my goods receipt.

Some days later I'm able to calculate the final price.

When I do MIRO, the price which is calculated and displayed is the same one as in the PO.

The question is: How can I enable price recalculation at the MIRO level?

By the way I have maintained the classical IS-OIL setting (IS-OIL Downstream -> MAP-> Formula & Average Pricing -> Define copy rules for invoice receipt) and it's still not working. Is there another setting to be maintained?
