The Multiple Currencies feature lets you create transactions with customers in currencies other than your company’s base currency. When you create a customer record, you set the primary currency and additional available currencies for transactions with that customer. The customer’s primary currency is the default currency for sales transactions. Aggregate balance information and credit limits are displayed in the primary currency.
You set currencies on the Currency sublist of Financial subtab of the customer record. The Primary Currency field is in the Account Information section. When you save a new customer record, the primary currency is automatically added to the list of transaction currencies on the Currencies subtab. You can add as many transaction currencies you need in the Currencies subtab. There is no limit.
When you create a sales transaction for the customer, you can choose any of the transaction currencies associated with the customer. You cannot remove a currency from a customer if transactions have been entered in that currency.
