DAX Programming References

Hi manojk_pbi,

Thank you for reaching out to the Microsoft fabric community forum. Also, thanks to Greg_Deckler, for his inputs on this thread.

I completely understand how overwhelming it can feel when you are looking for the right references to improve your DAX programming skills, especially when optimization is a key focus.

Microsoft provides some excellent official documentation and learning paths that can really help you build a strong foundation and then move towards advanced, optimized programming.

The complete Microsoft DAX reference, covering functions, syntax, and examples: https://learn.microsoft.com/en-us/dax/

Also, please refer this link: https://support.microsoft.com/en-us/office/quickstart-learn-dax-basics-in-30-minutes-51744643-c2a5-436a-bdf6-c895762bec1a

Hope this helps. If you have any doubts regarding this, please feel free to ask here. We will be happy to help.
Thank you for using the Microsoft Community Forum.
