Go to setup (via the main menu) and select users in the setup menu.
Click the '+ add user' button to add a new user. Assign one or more user roles to the user at the bottom of the pop-up screen.
Permissions per user role
Depending on a user's responsibilities and skills, an administrator can assign one or multiple user roles to a user profile.
Do you want to grant a user all permissions? Set the user roles 'administrator' and 'planner'.
Can I change certain permissions per user role?
No, permissions per user role are set and cannot be changed per account.
