A tip of using value-based hierarchy in AW
Posted by Dylan Wan on December 16, 2006
A value-based hierarchy is currently supported only in AW, the Oracle OLAP option.
I heard that OBIEE may support it in a later release after it supports the data source from AW.
A value-based hierarchy can be used to model the management reporting hierarchy, in which you do not have the specific “level” concept in the hierarchy.
If you have sales are rolled up to their manager, and sales managers are also selling products, you should craete dummy node as a child record of every sales manager so the sales data can be associated with the sales manager.
