Edit Dependencies Dialog Box
Use the Edit Dependencies dialog box, available from the Schedule tab of the Project Planning form, to enter details for the dependency. The details that you specify include the predecessor tasks, relationship type for each task, and any lag or lead time.
After you create a dependency, a checkmark displays in the task row's associated Dependency column on the Labor tab of Project Planning.
On rows with the checkmark, you can right-click and select Dependencies from the shortcut menu to view the Dependencies dialog box, which provides a display-only view of the predecessor and successor relationships that are created using the Edit Dependencies dialog box.
