Workforce Planning (Job Granularity) – supported approach to reverse/restore a departed job

Workforce Planning application is configured with Job granularity only; Employee granularity is not enabled.

The customer needs clarification on the supported process when a planned job/position is no longer required and is subsequently needed again in a future planning cycle.

Please confirm:

Is there a supported method to reactivate or restore a job after it has been marked as departed, terminated, or inactive in a Job-granularity application? If yes, please provide the steps, effective-period behavior, and required calculation rules.

Is the Plan Departure/Termination feature intended only for Employee-and-Job granularity? Is an equivalent Job-level departure process available or supported?
