Remember RANK() is a 1-based index

Because I just spent hours trying to figure out the second example that uses FILTER() I thought I'd leave this here.

Rank is 1-based but Item() is 0-based.With comments:WITH SET MYROWS AS FILTER( NONEMPTY( [Customer].[Customer Geography].[Customer].MEMBERS * [Date].[Date].[Date].MEMBERS , [Measures].[Internet Sales Amount] ) AS MYSET -
