Using Member Functions
A member function retrieves a member from a hierarchy, level, set, or tuple by traversing the absolute and relative locations of members within these objects. A member function can also retrieve members by resolving the string representation of a member.
Member functions, like tuple functions and set functions, are essential to negotiating the multidimensional structures found in Multidimensional Expressions (MDX).
