This activity is used to change the status of a work assignment to Cancelled. When rejecting a work assignment,
a reason for cancellation must be entered.
If the user selects a Cancel Cause with Do not reassign to me flag enabled, this
Work Task will not be rescheduled to the same resource that set the Work Assignment to Cancelled. If Scheduling
Solution is used, this will also create a Resource Preference with Preference 0, on the Work Task in
Work Task\Scheduling Information.
