Projects that contain solutions can get orphaned in some instances. For example, if a ATG Knowledge user creates a new solution and it moves in the workflow past the In Draft status, and is then discarded, the project containing it is orphaned and never deployed.
In cases like this, you can remove these orphaned projects in the BCC.
Go to Content Administration > Admin Console > Overview.
Click on the Site Name for your target server.
Select the To Do tab.
Select the projects that are orphaned and click Reject Selected Projects.
