Task Outline Number (assignment field)
Data Type Number
Entry Type Calculated
Description The Task Outline Number field contains the number that represents the associated task's position in the hierarchical outline structure. The task outline number is similar to a work breakdown structure (WBS) code, except that the task outline number is automatically entered by Project.
How Calculated Project assigns the assignment's outline number according to the associated task's sequence and outline level in the project outline hierarchy. The first task has an outline number of 1. The subtask that appears directly under that first summary task has an outline number of 1.1. The next subtask on the same level has an outline number of 1.2. The first subtask of that subtask has an outline number of 1.2.1. A task with an outline number of 7.2 indicates that it's the second subtask under the seventh top-level task.
Best Uses Add the Task Outline Number field to the Resource Usage view when you want to display the position of an assignment's task within the project's outline structure. If you use the outline numbers as WBS codes, this can help you identify tasks by number.
Example When reporting on assignment progress, you prefer to use the outline numbers rather than the task names. You add the Task Outline Number field to the Resource Usage view to see the outline numbers.
Remarks The Task Outline Number field is available only in the Resource Usage view, and not in the Task Usage view.
