Sequence number in task groups and tasks

The task management subsystem enforces the dependencies between tasks. These relate to any Sequence order you might have specified in the Change form.

For more information, see Assigning sequence numbers to dependent change requests.

When you include task group templates, task templates, or ad hoc tasks in a change request, they are automatically assigned a sequence number in the order in which you add them to the change request. More than one task can have the same sequence number; tasks with the same sequence number are considered peers. Peer tasks can be completed in any order among themselves.

Tasks must be completed sequentially. When the change request's status is set to Scheduled, the task with sequence number 1 is activated and its status is set to Assigned. When the last task is completed, the change request is closed.

To renumber a task group or task, you can use the arrow buttons next to the Tasks and Task Groups table on the Tasks tab of the Change Request. Tasks with lower sequence numbers, for example 1, must be completed before those with higher numbers, for example, 2, 3, or 4.
