You can delete events unused by schedules or other events. For example, if an external event is used to trigger a recurring event, the recurring event needs to be deleted or disassociated from the external event before the external event can be deleted.
To delete events from the Manage Events panel in the Schedule module.
Select Navigate, then Schedule, and then Manage Events.
An event list is displayed.
To filter the events list, select Filter from the toolbar area. Complete the Filter dialog and select Apply.
Select an event, right-click, select Delete and confirm deletion by clicking Yes.
If schedules are associated with the time event you are deleting, modify those schedules to use another time event.
Before you delete a time event associated with an external event, disassociate the time event from the external event or delete the external event.
