From Version 9 on, the display names of the cube elements in a category must be unique, and the category display names also should be unique in a business/report cube. Then, when you load a catalog which was created in a previous version in JReport Designer 9, if the catalog contains business/report cubes that have duplicate display names, the Rename Duplicate Display Name dialog will be displayed for you to rename the duplicate names. See the dialog.
The following are details about options in the dialog:
Duplicate Display Name
Lists all the cube elements and categories that have duplicate display names.
New Display Name
Specifies the new display names for the cube elements and categories.
OK
Applies the changes and closes the dialog.
Close
Does not retain any changes and closes the dialog.
