Forces a specified set to be evaluated within the current context.
Existing Set_Expression
Set_Expression
A valid Multidimensional Expressions (MDX) set expression.
By default, sets are evaluated within the context of the cube that contains the members of the set. The Existing keyword forces a specified set to be evaluated within the current context instead.
The following example returns the count of the resellers whose sales have declined over the previous time period, based on user-selected State-Province member values evaluated using the Aggregate function. The Hierarchize (MDX) and DrilldownLevel (MDX) functions are used to return values for declining sales for product categories in the Product dimension. The Existing keyword forces the set in the Filter function to be evaluated in the current context - that is, for the Washington and Oregon members of the State-Province attribute hierarchy.
