MDX Tuple Specification
An MDX tuple is a collection of member(s) with the restriction that no two members can be from the same Essbase dimension. For example, (Actual, Sales) is a tuple. (Actual, Budget) is not a tuple, as both members are from the same dimension.
This section shows syntax rules for tuple specifications.
