Definition:
One of the parent-nodes in the UCB Organizational Tree that occurs above the ORG_NODE described by this row of lookup table data.
A parent-node is a node "above" the ORG_NODE in question. For example, an ORG_NODE that corresponds to a Department will have parent-nodes that corresponded to a Campus, a Control Unit, and a Division. For each ORG_NODE, the DEPT_HIERARCHY_MAP view includes one row for every node above it, and one for itself.
