Sum and Sumx are functions that often founded to be misleading for many Power BI users. As both functions are doing the aggregation, it seems a bit confusing what is the actual difference between these two. There are many blog posts and articles about each function. I always explain the difference with simple demos in my courses and presentations, and people find it easy to understand. So, I thought better to explain it in a video for everyone to watch.
