I have created the Purchase order and confirm the PO.

And personalize the fields exchange rate onto the form

Click on the “fixed rate” default exchange rate has been auto populated based on system.

Now change the Exchange rates manually.

Do the product receipt.

Please verify the Voucher transactions.

Voucher transactions are calculating based on system. However it is not calculating based on fixed rates.

Actual result: product receipt vouchers are calculating based on system default Exchange rates.

Expected result: product receipt vouchers should be calculate based on Fixed rates manually what we have changed.
