OK, I’m brushing up on my skills, and need a little guidance to create a Measure to add to a Matrix…
Using the eDNA Practice Dataset, how do I show a % of sales per Full Name against Customer Name?.
Using a Matrix visual as per below: (on the left is Excel of what I want to achieve, column D, on the right is the matrix).
Hello @marcster_uk,
Thank You for posting your query onto the Forum.
You can use the below formula for the reference =
% Of Total Sales =
DIVIDE( [Total Sales] ,
CALCULATE( [Total Sales] ,
ALL( Regions[City] ) ) ,
BLANK() )
Note: The naming convention might be different in your file so incorporate it accordingly.
Hoping you find this useful and meets your requirements that you’ve been looking for. 
Thanks and Warm Regards,
Harsh
