Add System Roles to a User
From the System Roles tab of an application user record, you can assign applicable system roles to the user. When you assign the system roles to a user based on his or her job and responsibilities, the user sees only the tasks and features required to perform his or her specific roles. When you assign a system role to a user, you can also select the record level access for the user within the role.
Warning: While you can assign system roles from a user record, we recommend you assign users to a system role from the record of the role. For information about how to assign users to a role, see Assign Users to a System Role.
