In the case of a filter such as ?Top 10 SalesPeople for Q1 of 2012?, the context would likely be the measure (e.g. revenue) and the member 2012 Q1. Syntax: TopCount( children of salespeople, 10, tuple([Revenue], [2012 Q1]) ) If a dimension is not represented in the tuple function for a filter, then the default member of each dimension is used for the context. Within a Query Expression using the Rank function: Syntax: rank( TUPLE WITHIN SET ) Simple use case: User wants to see the rank of each Product Line for the year 2012. rank(currentMeasure DESC tuple [2012] WITHIN SET [Product Line]) NOTE: In this case, the context used by tuple is not placed in brackets.
