MDX Essentials : Set Functions: The DRILLDOWNMEMBER() Function
In this article, we will begin an extended examination of the MDX surrounding drilling up and down within our Analysis Services cubes. Comprising an analytical technique by which an information consumer can maneuver between summarized ("drilling up") and detailed ("drilling down") levels of data, drilling up or down occurs along the lines of drilling paths that are defined within the physical structures of our cubes. Often specified by the cube's dimensional hierarchies, these paths can also be based upon alternative relationships that exist within or between dimensions.
