In this video, you'll learn the newest and most powerful DAX Window Functions that make row-context calculations, running totals, top-N analysis, and comparisons dramatically easier — without complex CALCULATE + FILTER logic.

📌 What You'll Learn:
🔹 INDEX – Retrieve values from a specific row position within a partition
🔹 OFFSET – Compare current row values with previous/next rows (like LAG/LEAD in SQL)
🔹 WINDOW – Define custom row windows for running totals, moving averages & more
🔹 RANK – Rank rows within partitions based on any measure or column

💡 Why Window Functions Matter:
These functions simplify calculations that previously required complex DAX patterns — perfect for building dynamic rankings, period-over-period comparisons, and top/bottom N reports in Power BI.

👨‍🏫 Taught in Tamil for easy understanding, with practical Power BI examples you can apply directly to your reports.
