In Business Central it is not possible to post operational (customer/vendor) and financial (bank account) exchange rate differences to separate GL accounts. Both when registering payments in foreign currencies and running the "Adjust Exhange Rate" batch job. The separation is made only by

• Realized gains 
• Realized losses
• Unrealized gains
• Unrealized losses

The ideal solution would be to add columns for the financial (bank account) related currency differences so that users can define separate GL accounts.

Updated IFRS18 regulations as of 2027 (2026 as comparison) will require the division of operational and financial fx differences.
