Top 10 Values with Running Total

Hi venug20

try this, first create another measure for top10 sales, I named it top10sales, reason I added this new measure because total line of top10 items is not showing correctly:

Top10Sale2 =
 var myRank = [Rank] 
RETURN 
SUMX( 
VALUES(bi_product[Product]), 
IF(myRank <=10,  [Top10Sale] )
 )

We will use top n to get the list of products based on rank and then sum it up, if condition is to  avoid showing all the product and remove running total in the "total" line of the table.

Top10RunningTotal = 
IF( [Rank] <= 10 && HASONEFILTER( bi_product[Product] ), 
CALCULATE( [Total Sales], 
TOPN( [Rank], ALL(bi_product[Product] ), [Total Sales] )
 )
 )

Hope it is helpful,you can take it from here.
