Anyone know how to report the exchange rate used at the time on a sales order? I am just seeing the same rate for the whole year via Currency fields > Exchange Rate. We update exchange rates daily in the system. The exchange rate field on the order is just 1 regardless of the SO currency.

Exchange rate on the order itself is the rate used at the time of the transaction. You should review your setup if you expect something different than 1. Something may be glitchy
