Administrators can add and update system roles and specify their access permissions via the Role Access Data Loader. You must first populate in a comma-separated values (CSV) file the mandatory fields required for type of import (that is, adding a new role or updating an existing role).
To import system role data, your user role must have unrestricted access to the Role Access Data Loader feature in System Roles (Manage Features > User Manager Features).
To import role access data
