Rank based on multiple columns in matrix

[Anonymous]

Hello team,

I have a Brand & product column in heirarchy in matrix visual along with sales I want rank based on Brand If visual is not expanded and if visual is expaned then it should return rank based on product. I also have slicers on the page. 

 It should not have ties, My dataset has around 14 million rows so COUNTROWS doesn't seem to work. 

rankpro = IF(ISINSCOPE('Product Attributes'[Brand-Product]),RANKX(ALLSELECTED('Product Attributes'[Brand-Product]),[Sellout (P)],,DESC,Dense))

But it is returning ties.

Total Sales = SUM( Sales[Amount] )

Ranking = 
switch( TRUE(),
    ISINSCOPE( Products[Prod Name] ),
        var ProductsForRanking =
            CALCULATETABLE(
                DISTINCT( Products[ProductID] ),
                DISTINCT( Products[Brand] ),
                ALLSELECTED( Products )
