Top N Filter - Biggest changes

Hi depple 

If you have a visual showing any measure by Product, you can certainly filter Product to the Top 10 based on absolute variance.

I created a simple example PBIX here and did the following:

1. Started with a Sales Amount Variance measure (in my example a year-on-year variance)
2. Created a SalesAmount Variance Absolute measure:
   

   Sales Amount Variance Absolute = 
   ABS ( [Sales Amount Variance] )

3. Created a visual showing Sales Amount Variance by Product, with a Top N filter on Product, set to Top 10 by Sales Amount Variance Absolute,
4. To illustrate that it's working correctly, created a visual showing Sales Amount Variance without the filters, with a Rank measure defining the colour (based on this article😞
   

   Rank of Product by Absolute Variance = 
   IF (
       ISINSCOPE( Sales[Product] ),
       RANKX (
           CALCULATETABLE (
               VALUES ( Sales[Product] ),
               ALLSELECTED ( Sales[Product] )
           ),
           [Sales Amount Variance Absolute]
       )
   )

5. Appears as follows:

    

Hopefully that helps. Please post back if needed.
