Edit an activity dependency

You can edit, disable or delete activity dependencies. The project end date can change in these cases on the critical path (the activities and tasks where any change moves the project end date; critical activities show as solid red bars):

• If you disable an activity dependency on the critical path and then advance the activity's start date, the project end date moves earlier.
• If you enable a disabled activity dependency on the critical path, the project end date moves later.
• If you delete a dependency on an activity that has several predecessor dependencies, the project end date may change.

The activity's dependencies are listed in its Dependency list tab.

Edit a dependency

1. Double-click the activity bar.
2. Click the Dependency list tab.
3. Hover over the dependency you want to change. The Edit (pencil icon) and Delete (bin icon) icons appear.
4. Click Edit.
5. Make your changes.
6. Click Save.

The Edit pencil does not show for dependencies with a negative lag.

Delete a dependency

1. In the Dependency list tab, hover over the dependency.
2. Click Delete (bin icon) beside Edit.
3. Confirm the deletion.

You need permission to delete activity dependencies.

Enable or disable a dependency

Each dependency has an on/off switch at its left. It is on (enabled) by default. Turn it off to disable the dependency. If you do not have permission to edit dependencies, the switch is greyed out.

Once you disable or delete a dependency, the old predecessor or successor no longer affects the activity. If the activity is on the critical path, this affects the overall project completion date.

Editing a task dependency works the same way. See Edit a task dependency.
