After moving, deleting, or rearranging tasks, their custom work breakdown structure (WBS) codes (WBS: A hierarchical structure that is used to organize tasks for reporting schedules and tracking costs. With Project, you can represent the work breakdown structure by using task IDs or by assigning your own WBS code to each task.) may no longer be in the correct sequence. You can renumber the WBS codes of all or selected tasks.

1. On the View menu, click a sheet (sheet: A spreadsheet-like representation [in rows and columns] of task or resource information. Each row specifies an individual task or resource. Each column [field] specifies a type of information, such as start dates or standard rates.) view that contains the tasks you want to renumber, such as the Task Sheet.

   To use a view that is not on the View menu, click More Views, click the view you want to use in the Views list, and then click Apply.

2. In the Task Name field, select the tasks you want to renumber.

   To select adjacent tasks, hold down SHIFT, and then click the first and last tasks you want.

   To renumber WBS codes for all tasks, you don't need to select any tasks.

3. On the Project menu, point to WBS, and then click Renumber.
4. To correct the WBS code sequence for selected adjacent tasks, click Selected tasks.

   To correct the WBS code sequence for all tasks in the project, click Entire project.

Notes

• The first task in a selection of tasks is not renumbered. It is used as the reference for renumbering the other tasks.
• If your project contains subprojects, you can renumber some or all tasks in the subproject by displaying all subtasks. Click Show , and then click All Subtasks. Microsoft Office Project 2003 cannot renumber tasks that are not displayed.
• To display WBS codes, you can add a WBS column to a sheet view.
