The Remove Jobs from Schedule removes all the scheduled jobs listed in the job grid from the existing schedule.  The jobs to be removed from the existing schedule must already be scheduled with valid schedule dates.  If the job is not scheduled or does not have a job state of a schedule type, then the job is ignored during the remove process.

When you select to Remove Jobs from Schedule DMS verifies the remove by displaying a window as in the example below:

If you select Yes, the jobs currently listed in the job grid that are scheduled will be removed from the existing schedule.  If you select No, the jobs are not removed from the schedule.
