Exchange Rates -Divsor picked

Hello All,

We have update exchange rates method from Divisor to Multiplier ( Z TO Y ), system work perfectly correct when enter invoice date /gl date as current date , but when we entered old date for invoice , it's picked Divisor rates , even though we manually entered multiply rates at the time of voucher booking.

Please help us to solve this problem . -P0411-Standard Voucher Entry &  PO Voucher Entry.

Thanks,
