In Dynamics 365, exchange rates are not always recalculated automatically:
🔹 When Exchange Rate IS Applied
- At the moment a record with currency fields is created.
- When a money column in the record is updated.
- When the state of the record changes (e.g., draft → submitted).
🔹 When Exchange Rate is NOT Applied
- Simply changing a non-money field (like quantity) doesn’t trigger recalculation.
- Viewing a record later still shows values based on the exchange rate at the time it was last assigned, not the latest rate.
- Currency updates in the system don’t retroactively update existing records.
💡 Takeaway: Exchange rates are point-in-time values unless the record’s money fields or state are updated.
