For Oracle Hyperion Planning and Oracle Essbase, the Alias dimension or table is required to support languages. Keep in mind these special considerations:
The Alias dimension must include a member named "Default."
If the dimension name is not the same as the Alias name in an Oracle Hyperion EPM Architect Planning application, the drill through landing page does not return any data.
When creating Alias table members in a dimension, define them with the same name that is displayed in Oracle Fusion, E-Business Suite, or PeopleSoft. This is the value of the NLS_LANGUAGE column.
