The option that is available in FAW for synchronizing users and job roles between FAW and Fusion Applications is to implement SSO and synchronization of users and job roles between FAW and Fusion Applications, before provisioning the FAW instance. This will allow you to avoid creating Fusion Applications users and their assigned job roles in FAW, as they will be automatically synchronized from Fusion Applications4. You cannot use the FAW console security option or the Bulk Load option in FAW to do the synchronization.
