Prior to import, user should check the Primary Currency of the vendor record and compare it with the currency of the item being imported.
If Multiple Currencies feature is not enabled, user will have to decide if:
1. A new vendor record with the same currency as the item will be created
2. User will change the value of the Primary Currency field (if there is no transaction yet for the vendor) to match the currency of the item being imported
3. User will change the currency for the item in the CSV file to match that of the vendor's Primary Currency
If Multiple Currencies feature is enabled, user can add this option:
4. Add the item's currency in the Financial tab > Currencies sub tab of the vendor record
