title: Power BI grand total on top N wrong percent
body: <p>I am running in this issue:
  I want to display top 5 order on items list, and show the overall %.</p>

  <p>As you can see on the left table, item H has 60 orders and an overall of 21.05%
  Now I want to see only the top 5, but with the same % overall and not 28.57% as you can see on the right table.</p>
  
  <p>The filter is pretty easy.</p>

  <p>I guess it can be resolved using DAX, but can't find the correct formula.</p>
  
  <p>Please help.</p>
