For project task dependencies, object and field Read permissions are required to display them in Gantt. If any permissions are missing, the project task dependencies are not displayed.

For project task assignments, object and field Read permissions are required to display them in Gantt. If any permissions are missing, the project task assignments are not displayed.

For the start and end dates on a project:

• If you don’t have Read permission for the Start Date field for the project, the Project Start marker is not displayed.
• If you don’t have Read permission for the End Date field for the project, the Project End marker is not displayed.
• If project start and end dates are not loaded into Gantt, the Project Start marker aligns with the earliest task start date and Project End marker aligns with the latest task end date.

For work calendars:

• If you don’t have Read permission for the Work Calendar field on the Project object, the project work calendar is not loaded into Gantt.
• If you don't have Read permission for the Work Calendar field on the Project Task object, no task work calendars are loaded into Gantt.

If work calendars are not loaded, non-working time on the project is not displayed.
