If you create alias tables with aliases for Account, Currency, Entity, Scenario, Period, Version, Years, and user-defined dimensions and members, you can select a default alias table for the application. Users can set preferences for which set of aliases (stored in an alias table) to use for displaying member and dimension names.
To select the application’s default alias table:
Select Current Application Defaults, and then select Application Settings.
In Member Name\Alias Display, select the option that enables the kind of member data to be displayed on the Member Selector throughout your application:
Default—The data determined by the form, grid, or dimension settings
Member name —Just member names
Alias—Just member aliases, if defined
Member name : Alias—Names followed by aliases, if defined
Alias:Member name—Alias, if defined, followed by the names
