Use country dimensions to track business activities in multiple countries. If you track business activity in the U.S. and Canada, for example, the country dimension should contain states, provinces, and countries. If a dimension is tagged as country, you can set the currency name property. The currency name property defines what type of currency this market region uses.
In a country dimension, you can specify the currency used in each member. For example, in the Interntl application and database shipped with Essbase, Canada has three markets—Vancouver, Toronto, and Montreal—which use Canadian dollars.
This dimension type is used for currency conversion applications.
