Scheduling Dependent Tasks Using the Gantt Chart

The Schedule tab includes a grid and an interactive Gantt chart where you can create dependencies between tasks.

You can only create dependent relationships for items that are at the lowest level of the Work Breakdown Structure (WBS). These are the lowest child-level, or lowest leaf nodes, of the WBS. They display under a parent level but have no WBS children of their own. For the purpose of task dependencies, these are referred to as "tasks" but they may be phases, tasks, labor codes, or lower indent levels, depending on the WBS structure.
