In today's data-driven world, speed and efficiency are paramount. Your Power BI reports might be visually stunning and packed with insights, but if they take an eternity to load or interact with, their impact diminishes significantly. This is where the Power BI Performance Analyzer becomes your best friend.

As a data professional in Pune, Maharashtra, India, I've often seen teams struggle with sluggish Power BI reports, leading to frustration and reduced productivity. The Performance Analyzer offers a powerful yet accessible way to pinpoint performance bottlenecks and optimize your reports for a smoother user experience.

Combine Python and Power BI for deeper insights, advanced analysis, and powerful visuals. Enhance your data workflows with seamless integration.

Have you ever written a DAX measure with HASONEVALUE() and thought — “This should work!” — only to see it break unexpectedly?

Or maybe you tried ISINSCOPE() and magically, everything worked.

Both functions seem to answer the same question:

“Am I at the leaf level of a hierarchy or not?”

A sleek Power BI dashboard might look perfect, but what if it’s lying? This article uncovers how poor data preparation can create misleading KPIs, false rankings, and costly decisions. Through a shocking real-world example, you'll learn how to avoid silent analytical traps and apply best practices that ensure trustworthy insights.

With every monthly update, Power BI becomes smarter and more user-centric. One of the most revolutionary enhancements introduced in 2024 and improved through 2025 is the Visual Calculations feature.

This blog is Part 7 in our series on Power BI Enhancements You Need to Know, and we’ll deep dive into what visual calculations are, how to use them, key functions, real-world use cases, and known limitations—all with hands-on examples.

Have you ever written a DAX measure, double-checked it, and still ended up with a result that made absolutely no sense?

Yeah… same here.

In this blog, we break down one of the most frustrating (and surprisingly common) mistakes in DAX: when a variable quietly breaks your logic.

You’ll learn:

• Why your filtered measure might be ignoring filters entirely

• How evaluation context works behind the scenes

• When using a variable helps instead of hurts

• A practical example you can recreate in Power BI

Whether you're just getting started with DAX or looking to deepen your understanding, this article will help you finally make peace with variables and avoid sneaky bugs in your measures.

➡️ Let’s dive into the logic, the gotchas, and how to fix them for good.

In my latest blog, I share how I worked around two known limitations — triggering specific forms from Power BI and fixing the app visual's rendering issue — all without compromising user experience.

Most of us used Calculation Group as a tool for Time Intelligence measures (YTD, QTD, MTD, YoY and etc). That is true, but we can do so much more than that. In this blog I will walk you through Time Intelligence and Non Time Intelligence use cases which will highlight how flexible and powerful is the Calculation Group. 

In Power BI, effective collaboration and streamlined report lifecycle management are essential. Imagine eliminating the need to repeatedly click the "Publish" button—Power BI’s integration with OneDrive and SharePoint makes this possible through automatic report updates in the Power BI Service.

Field Parameters in Power BI are a powerful feature that enables users to dynamically select and toggle between different dimensions or measures within a report visualization. This feature enhances user interaction by offering a simplified way to explore data without requiring complex DAX calculations. In this guide, we’ll delve into what Field Parameters are, why they’re important, and how to effectively use them in your Power BI reports.
