In the payment application page of a deposit or cash receipt, users can elect to write-off balances to Payment Discount or Payment Tolerance. If the variance relates to a difference in currency exchange rates, the system will debit either the payment discount or payment tolerance G/L Account, as defined in the Customer Posting Setup. The user would then need to post a General Journal to credit the G/L expense account it was written off to and debit Realized FX Losses. It would be nice to have an option to write off balances to foreign currency gains/losses and have the difference post to the Realized FX Losses G/L Account. I believe this may require new fields in the Customer Posting Group setup page, but would be a huge benefit to a lot of customers.
