What option allows an administrator to manually add members to the dimension worksheet in Cube Designer?

The correct choice indicates that administrators can manually add members to the dimension worksheet in Cube Designer through the application workbook. This method allows users to access the overall structure and data organization of the cube, providing an environment where they can create or update dimensions and their respective members directly. By using the application workbook, an administrator can efficiently define and manage the characteristics and metadata associated with specific dimensions, ensuring that the cube reflects the intended analytical structure.

In contrast, the other options do not provide the direct capability for adding members to the dimension worksheet. The "To Sheet" option typically would be used for transferring or moving data to a sheet, rather than adding members. Selecting "From Sheet" usually implies importing members from an existing spreadsheet, which may not allow for the creation of new members as required in this context. The option involving exporting the cube could lead to data being saved or transferred out of the current environment, but it does not facilitate the adding of new members within the dimension worksheet itself.
