Can you help ow to learn dax

[FBergamaschi]

Hi @Poojajunnu,

step 1 is books or video courses (electronic version is preferred)

books

- Supercharge Power BI (introduction to DAX)

- The Definitive Guide to DAX (high-level DAX)

video courses

- SQLBI.com (Introdction to DAX - free course - and then Mastering DAX)

step 2 apply it every day to your job via Power BI or Power Pivot

Avoid quick courses on the web, stay n trusted and renowed professional, understand what you are doing in DXA even for very simple initial steps

If this helped, please consider giving kudos and mark as a solution

@me in replies or I'll lose your thread

Hi @Poojajunnu 

Start with these, then practice a little every day:

Books (start with one)

• Supercharge Power BI: Matt Allington

• The Definitive Guide to DAX: Russo & Ferrari: https://www.sqlbi.com/books/the-definitive-guide-to-dax/

Free learning (Microsoft Learn)

• DAX overview: https://learn.microsoft.com/en-us/dax/dax-overview

• DAX basics quickstart: https://learn.microsoft.com/en-us/power-bi/transform-model/desktop-quickstart-learn-dax-basics

• Time intelligence: https://learn.microsoft.com/en-us/dax/time-intelligence-functions-dax

YouTube

• Guy in a Cube : https://www.youtube.com/c/GuyinaCube

• SQLBI : https://www.youtube.com/c/SQLBI

What to actually focus on

• Row context vs filter context

• CALCULATE() + context transition

• Iterators (SUMX, AVERAGEX, …)

Tip: Don’t try to memorize every function. Get comfortable with context, then read the function docs as needed and apply.
