You use multicurrency accounting if you want to process receipt transactions and shipment transactions, maintain price lists, and fill orders (using Order Entry) in more than one currency.
To create a multicurrency Inventory Control system:
Sage 300 includes a large set of currency codes that use standard international abbreviations and the format and number of decimal places that are normally used with each currency. You probably will not need to define new codes unless you do not use the international codes.
You can select the Multicurrency option for Inventory Control at any time. However, once you select it (and save your changes), you cannot change Inventory Control back to a single-currency ledger
You do not need to enter multicurrency totals for Inventory Control sales statistics, because the program keeps these statistics in the functional currency.
