9. To edit the one-time exception, click the teal-highlighted date in the
calendar. The Edit: <
exception name
> dialog opens. This dialog lists the
events that are scheduled to occur on the selected date.
The intervals specified by the events in the one-time exception are
highlighted teal, and the events in the daily schedule are highlighted
grey. When events in the one-time exception end, their priority is reset to
255 and the schedule reverts to the regular daily schedule. Thus, the
highest priority event in the applicable daily and exception schedules
that was supposed to occur prior to the event in the one-time exception is
executed. If there are no such events, the next highest-priority event
executes at its regularly scheduled time.
Creating Exceptions
You can create an exception or recurring exception in the Event Scheduler. An
exception is an alternate daily schedule that is used over a range of dates. A
recurring exception is an alternate daily schedule that is used over a range of
dates in a specific pattern (such as every third Sunday). To create an exception
or recurring exception, you set the dates of the exception and then create the
events in the exception.
