Stop getting incorrect rankings in your reports! This is the ultimate guide to mastering TOPN vs. RANKX in Power BI, revealing the critical difference that will lead to smarter, more accurate dashboards.

The built-in 'Top N' filter seems like a quick solution, but it has a hidden pitfall: it often fails to respect the other groupings in your visual. This can lead to misleading data, especially when you need to rank items within categories like Year, Region, or Product.

In this deep-dive tutorial, Pragmatic Works' Data Engineer Mitchell Pearson walks you through a real-world scenario to expose this common problem. You'll learn why the dynamic, context-aware RANKX function is the superior choice for reliable categorical ranking and how to implement it step-by-step for smarter dashboards.
