Define a schedule

Schedules are configured with two types of records.

About this task

  • Schedule records specify a time zone and a type of schedule and use one or more schedule entries. Schedule records are saved in the Schedule [cmn_schedule] table.
  • Schedule entry records specify the time periods that are included or excluded from a schedule. Schedule entries are saved in the Schedule Entry [cmn_schedule_span] table.


  1. Navigate to System Scheduler > Schedules > Schedules.
  2. Click New, enter a unique and meaningful Name and Description and then fill in the form.
    Note: If there are no active entries defined for the current schedule, then the Schedule form displays a warning message. If your schedule is a child schedule that contains only exclusions, ignore the message because exclusions are non-active entries.
    Field Description
    Name Unique name for the schedule.
    Time Zone Time zone for the schedule. If you select Floating, the time zone is relative to whatever process is accessing the item at the time.
    Parent Parent schedule to constrain the new schedule.
    Application Application scope of the schedule.
    Type Text label that describes the purpose of the schedule. You can also use one of these system terms to determine how to process certain schedules:
    • excluded: excludes time periods from SLA counts.
    • maintenance: specifies time periods where change management activities are allowed. A schedule that contains maintenance schedule entries cannot also contain blackout schedule entries.
    • blackout: excludes time periods from change management schedules. A schedule that contains blackout schedule entries cannot also contain maintenance schedule entries.
  3. Right-click the header bar and click Save.
    Note: If you create a schedule of type maintenance and save the record, a UI policy hides the Type field from the form. To view or change the Type value, view the list of schedules rather than the schedule form and then add the Type column if necessary. You can click the cell for the value in the Type column and modify the value in the list view.
  4. Configure one or more schedule entries.
