Currency and Credit Currency Information
You can have only one currency per order. You can change the currency for the order before lines are added. The default value for the currency comes from the value established on the General Info page for the customer.
When you are viewing customer available credit, the system uses the Credit Check Currency field to bring all open receivables in multiple PeopleSoft Receivables business units to a common currency. If the customer has open receivables with different currencies in different PeopleSoft Receivables business units, the system converts the open amounts to a single credit-checking currency and then subtracts them from the customer's credit limit. The credit-checking currency can be different from the sales-order transaction currency.
