Voucher match issue - Amount does not balance to gross

Hi all,

User is trying to do voucher match, there is an error - AMOUNT DOES NOT BALANCE TO GROSS.

for eg :- the order is created in the month of september and received the exchange rate was 0.8999, and in the month of January the user is doing voucher match where exchange rate is 0.8355.

             so while doing voucher match this error occurs.

          But while i did a test in lower environment by using the exchange rate as 0.8999 while doing voucher match it work for me, kindly suggest is it a proper solution.

Currently we are using JDE 9.1, i check the Processing option in tab process for 15. rounding off is not there.
