Structural Authorization

Goodday to all,

I have issue to create roles for structural authorization

Transaction code involved is OOSB & OOSP.

OOSB - Assign Structural Authorization

OOSP - Authorization Profiles

I need to make sure this roles can do roles assignment to user id via OOSB but via OOSP, user admin can only display the profiles not editing it.

Please assist.

Thanks.
