Type Mismatch error in MDX on PowerBI visual

[Anonymous]

I am struggling with the Type Mismatch error when I query the cube in SSAS. The MDX query is shown below:

WITH MEMBER [MEASURES].[TopNFilter] AS IIF( COUNT( EXISTING EXISTS( [DimClient].[Client].CURRENTMEMBER, TopNSet)) > 0, 1, -1) 
SELECT {​ [MEASURES].[Volume], [TopNFilter] }​ ON COLUMNS, {​TopNSet}​ ON ROWS FROM Cube

 when I query the cube it throw error message "Type Mismatch" . I followed the solution in the link below:  

Solved: TOPN using SSAS MD - Microsoft Power BI Community

but still get the same error.

Thanks

Hi, @Anonymous 

I am not familiar with MDX. I'd like to suggest you go to SSAS forum which is more prefessional on this kind of problem.
