What is the difference between Institutional Hierarchy and Institutional Role function in BB Learn? Both are segregates user into group. Our institution is planning to use the hierarchy nodes. We have 6 campuses. Each of them have assigned a person to administer at the campus level. Would it be possible if the same user_id admin managing 2 campuses without viewing other campuses content? What is the purpose of having institutional role while the user already tied to the hierarchy node, some grouping under administrator and the rest grouping under user into node.
