Open the Power BI file in the above folder. Sadly, the running total column is blank:
Your task is to get the column to show what it says it should!
Combine the FILTER and EARLIER functions to get the Cumulative Oscars column to be correct:
The first few rows showing the cumulative total of Oscars won.
The table makes much more sense if you sort it in release date order:
Better - you can infer from this that All Quiet on the Western Front won 2 Oscars.
Now create another calculated column called Cumulative Oscars using variables to do the same thing, but this time storing each film's release date in a variable first (and thus avoiding using the EARLIER function).
Save this file as Oscar inflation, then close it down.
