The Dependencies section for detail panes can be found in these detail sheets:
The Dependencies listed show when a team is receiving or supplying information.
A following arrow indicates the primary team assigned to the activity is receiving information from another team through the listed dependency (a left arrow in the Gantt view name column).
A leading arrow indicates that the primary team assigned to the activity is providing information to another team (a right arrow in the Gantt view name column).
Adjust the width of the detail pane to display long names if needed.
