Gantt (Beta) enables you to create and manage project tasks in sandbox orgs only, and not to manage live projects.
This feature is in development and is not currently supported in PSA. If you enable Gantt (Beta), you are acknowledging this information and agreeing to provide feedback to help us with future development.
When you have opened Gantt (Beta) from a project, any existing tasks, dependencies and project task assignments (PTAs) are loaded.
You can use Gantt (Beta) to:
Load project tasks, dependencies and project task assignments (PTAs) from existing projects.
Create, modify and delete project tasks.
Create a task hierarchy, and add dependencies and lag durations between tasks.
Assign resources to project tasks, add and view resource percentage allocations for PTAs, link a resource to an assignment or resource request, and open the native assignment or resource request.
Add estimated hours for tasks, and view actual hours entered on timecards for tasks.
Link to existing pages to create assignments and resource requests for project tasks.
View projects over different time periods between hours and years.
