how to update manually the exchange rate ?

AI generated answer (using internal Slack threads):

To manually update the exchange rate in NetSuite, you can follow these steps: 1. Navigate to the currency record that you want to update. You can do this by going to Lists > Accounting > Currencies. 2. Click on the 'Exchange Rate' tab. 3. Click on 'New Exchange Rate'. 4. Enter the new exchange rate and the effective date. 5. Click 'Save'. Please note that you can only update base currency rates, other rates are derived rates and not updatable. If you have a large number of exchange rates to update, you can do this via CSV import. Prepare a CSV file with the new exchange rates and their effective dates, and then import this file into NetSuite. However, please be aware that manually created rates will not be deleted or updated to match auto-created rates through revaluation. Revaluation will use the rate from the last day of the month. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
