When a user creates an Opportunity in CRM, the system sets the value of the Estimated Revenue (Base) according to the exchange rate that is set at that time. Like most companies, we change our exchange rates regularly. Again I'm sure like most companies, we want open Opportunities to be converted according to the current exchange rate. So if someone enters an Opportunity with a value of AUD1,000, and the exchange rate to the base currency (USD) is 1.4, then the Estimated Revenue (Base) will be set to USD714.29. At the end of the month, if we revise the exchange rate to 1.35 we want the value of the open Opportunity to show as USD740.74. This is logical since the real value of the Opportunity in the Base currency will only be final it is Closed (either as won or lost). But the system seems to keep the value set to USD714.29 regardless of how we change the system exchange rate. Is there an option to have it show the Estimated Revenue (Base) so that it reflects the current system exchange rate? Alternatively, is there a way to have the system reset all open Opportunities to reflect the current exchange rate?
