You can rename applications for which you have Create/Delete Applications permissions.
When you rename an application, the application directory (ARBORPATH\app\appname) and some application objects, such as the application log, are also renamed.
To rename applications:
From Enterprise View or a custom view, select an application.
Right-click, and select Rename.
In the Rename Application dialog box, enter a new name for the application.
Click OK.
If the application contains locked objects, Essbase displays a list of the objects and indicates who locked which object at what time.
If a list of locked objects is displayed, unlock objects and complete the rename operation by clicking OK.
If you do not have Administrator privileges, you can unlock only objects that you locked.
Provided that all objects are unlocked, Essbase renames the application and updates Enterprise View.
