Understanding Multi-Currency

If the company has application users (or prospects) in multiple countries using different currencies, the system administrator can enable multi-currency support. If Multi-Currency is enabled, some Infor CRM views display information or options specific to your selected currency rate. For example, if you are using the British Pound as your default currency, opportunities display pricing in pounds.

You can set your default currency on the Opportunity tab in options. See Setting Opportunity options
