Scheduling a summary task
When you insert a schedule, Schedule Manager shows the schedule summary task in the resulting subschedule. This task, the first task in the task table, represents a roll up of the entire subschedule. It contains rolled-up information from all the tasks in the schedule including: earliest start, latest finish, total estimated work, total work completed, status, and percent complete.
- In the task table, the schedule summary task is displayed as the schedule symbol.
- In the Gantt chart, the schedule summary task is displayed as a black bar.
In the example structure, Master Schedule is the master schedule, and Sub-sched-A and Sub-sched-B are subschedules.
The schedule summary task applies to both schedules and schedule templates.
The schedule summary task cannot be updated directly, it cannot contain dependencies, and you cannot assign resources.
Note: You cannot edit any summary task from My Teamcenter.
You view the schedule summary task properties by using the Properties dialog box.
Note: When a task within a subtemplate is updated such that it causes its summary task to be updated, the master schedule summary task must also be updated. If the user does not have access to the master template, a flag is set and Schedule Manager updates the master schedule summary task the next time the master schedule is opened.
