Populate changes to WBS codes within the database

Changes to the task codes in the schedule are automatically saved as you make them. You do not need to save them yourself.

To regenerate saved codes on certain tasks in the schedule, instead of editing each task code, select the tasks on the schedule and choose Schedule→WBS→Regenerate.

When you choose Schedule→WBS→Regenerate All, all the previously saved codes are cleared and the new codes are generated automatically, based on the format and initial value of the schedule.

Note: If you are upgrading from a version prior to 11.2, you must generate the WBS codes for any schedule that did not contain WBS codes, using Schedule→WBS→Regenerate. In version 11.2 and later, Schedule Manager can set the WBS code on a newly created task only if there is a generated code for the schedule.
