Edit Supplier Currency in P4310

Hi All,

After raising a Foreign Purchase Order, is there a way to edit the Supplier Currency.

Raised a PO (via MRP) with Supplier Currency as USD and Company (Branch Plant) Currency as INR.

Now we would like to revise the Supplier Currency to EUR for one time ( we don't want to change the Supplier currency in the supplier master)

How to ACHIEVE THE ABOVE?

Thanks in Advance.
