What is the fifth currency?

A fifth currency value can be defined either as fixed currency or as a variable currency. However, the value cannot be entered or held on the transaction itself. Only the fifth currency code and currency rate can be entered and held on the transaction.

The fifth currency value can be calculated in reporting.

The fifth currency value can be calculated automatically from any of the other four currency values available on the transaction. This choice is made in the 5th Currency Calculated From field on the business unit setup.
