Delete External Task Dependencies

Use the External Dependencies dialog box to delete external dependencies. When you delete an external dependency relationship, you do not delete the task from the project. Instead, you delete the dependency link between the tasks. After removing the dependency, you can change the project's scheduling and run Autoschedule after removing the dependency.

If you delete an external task from its originating project, which is an external dependency in a sub-project, the external dependency is removed from all of its related task records in all other projects.

To delete an external task dependency

1. Select Dependencies from the External group in the Project ribbon.

   The External Dependencies dialog box opens.

2. Select the externally dependent task you want to delete, and click Delete.

   The selected external dependency is removed from the grid and project.
