Auto recognition of Realized gain/loss in the bank statement

Summary:

Hi all,

We have a scenario where a receipt is entered for the foreign currency ( $ Receipt ) and is remitted to the ledger currency bank account (LKR Bank account). The amount at which the foreign currency receipt realized in the bank is a different rate which results in the exchange gain / loss

When uploading the bank statement in LKR the original transaction currency was given as USD and the respective exchange rate is also specified. The expectation is that the system should auto recognize the exchange gain / loss through auto or manual reconciliation. However, its not working as expected instead at the point if manual reconciliation it throws an error that the "Tolerance should be defined".
