To remove a parent-child project link
You can remove N-level deep child relationships using this procedure. That is, you can remove "grandchild" and "great-grandchild" relationships, and so on.
1.
Navigate to the Summary tab of the parent project.
2.
Click the Manage Linked Objects icon (Page with pencil and linked chain image) and select Remove.
A dialog box appears, where you specify project(s)/request(s) to remove.
*
The list contains children from all levels; that is all children, direct and indirect, appear on the list.
3.
In the Linked Project... field, select the project(s) to remove as children.
4.
Use the >> and << buttons to move projects into or out of the Selected Items to Remove list box.
5.
Click Save Changes to remove child links to the project(s) you selected.
The project requests and projects no longer appear in the list on the Summary tab of the project.
*
Removing the link does not remove or delete the project; it simply removes the relationship.
