In Import cycle , Invoice is done at first fron the bill of Entry and then purchase order. Now at the at the time purchase order the currency rate was 1EUR =39 INR. is defined in PO itself.
After one month , GRN is done and at the time of GRN the currency is 1 EUR = 50 INR.
My question is to take care of the currency fluctuation in this case?
