What must occur before a dimension can be deleted?

For a dimension to be deleted in Workday Adaptive Planning, data removal must occur first. Deleting a dimension involves removing all associated data tied to that dimension. This ensures the integrity of the planning model and avoids any orphaned data that can lead to future discrepancies or confusion in reports and analysis.

Before a dimension can be safely deleted, it is essential to ensure that any related data is properly cleared, as retaining data without the dimension creates a disconnect. This step guarantees that when the dimension is removed, there are no dependencies that could cause errors or incomplete datasets.

Other options like data migration, dimension approval, or access revocation do not directly address the prerequisite of clearing the actual data associated with a dimension that must occur in preparation for deletion. Thus, data removal is the crucial step that must be taken before a dimension can be completely eliminated from the system.
