When using Advanced Currency Management with dated exchange rates, the converted currency amount is determined based on the opportunity’s close date, regardless of the opportunity stage. Here’s why:

Currency Conversion Based on Close Date: Advanced Currency Management applies the exchange rate effective on the opportunity’s close date, which means that the conversion is tied specifically to this date and does not depend on the opportunity’s stage.

Accurate Historical Currency Data: This setup ensures that historical exchange rates accurately reflect the currency rate as of the close date, providing precise financial reporting.

Salesforce Documentation: Salesforce outlines that Advanced Currency Management uses the close date for converting amounts on opportunities to account for dated exchange rates, providing consistency across all transactions.

In summary, the close date regardless of the opportunity stage (Option C) determines the converted currency amount when Advanced Currency Management is enabled.
