Customize the Gantt in More Ways
Where: This feature applies to Lightning Experience in Enterprise, Performance, Unlimited, and Developer editions with the Field Service Lightning managed package installed.
How: To use the new permissions in existing orgs, first assign them to users. For example, add them to these custom FSL permission sets: FSL Admin, FSL Dispatcher, and FSL Community Dispatcher.
After you assign extended permissions to users, you can activate them in. Activation is required only once and is irreversible.
Remove permissions from users as needed to restrict access. For example, to make the Gantt read-only for certain users, assign the permissions to the custom permission sets and activate them. Then disable the Enable Gantt Locker permission for those users that should have a read-only view of the Gantt.
