On a project change order work breakdown structure, you can:

• Add three types of lines:
  • Project - You can only add projects to the root project line.
  • Subproject - You can only add subprojects to project lines. You can add subprojects to both new and existing project lines.
  • Task - You can add tasks to any line in the work breakdown structure. You can add tasks to both new and existing lines.
• Change the values of existing lines. For a line of task type:
  • Project, you can only change the description.
  • Standard, you can change almost all values.
• Stop existing tasks.

Notes

If the project is created from a project execution quotation, you also create an activity in the project change order WBS. In this case, in the Project field, link the activity to the relevant (sub)project of the related project quotation WBS. If the project change order is confirmed, and a progress bill report is created, the activity is shown under the right project.
