After we do revaluation, the journal would be automatically posted to account “Realised Revenue exch diff-System". Can we change to another account? How to do so?

The Exchange Gain or Loss account is the default system-assigned account for recording exchange rate differences, wq32. Its functionality cannot be changed as it is configured by the system.

When revaluating currencies, the balances are automatically posted to the Exchange Gain or Loss account, labeled in your case as Realised Revenue exch diff-System. To allocate the balance to a different account, you can use a journal entry to reclassify it. I recommend consulting with your accountant to ensure the adjustment aligns properly with your accounting records.

Please don’t hesitate to reach out if you have any additional questions or concerns.
