Hi Richard,

Drag the table calculation onto the Measures pane so you can save it as a new field (I titled it Invoice Price Pareto). With this new a Measure, you can use it in a calculated field:

First 80%:

WINDOW_SUM(IF [Invoice Price Paretto]<.8 THEN COUNTD([Global DUNS]) END)

Last 20%:

WINDOW_SUM(IF [Invoice Price Pareto]>=.8 THEN COUNTD([Global DUNS]) END)

You can remove the IF statement if you want the total. So here they are all in the title:

Hope this makes sense!

Best,

Bryce
