It has been 3 years since I first wrote an article about SUM() vs SUMX() and a year since I wrote the first version of this article. Over the years I have been teaching DAX, I have learnt new and improved ways to explain some of the more complex topics. This article is one of the most frequently read on my blog site and I wanted to update it to continue to improve the value people get from my site. Even if you have read this article before, why not take another look and refresh your knowledge.
