For Planning and 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 a Performance Management ArchitectPlanning 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.
