In SuiteBilling, the Revenue Element’s exchange rate is sourced from the subscription/transaction rather than being independently overridden on the Revenue Plan. NetSuite’s documentation confirms that changes to the source transaction’s Exchange Rate update the Revenue Element, while Revenue Plans can then be updated from the revenue arrangement. I can review the subscription, revenue element, and source transaction to determine the cleanest way to apply the required rate without unnecessarily changing the exchange-rate table.
