Hi Maven Analytics Team,

As I progress on my journey using Power BI, I noticed that more attention is being drawn to User Defined Functions (UDFs). I think this will be a really nice addition to either the Desktop or Advanced Power BI course because it provides users with the ability to re-use certain functions instead of creating them from scratch.

It will also be nice to have a few use cases with the DAX Lib library of functions - just to introduce us to what it is and how we can use it in our work or projects.

Furthermore, pointing out the differences between UDF, calculated groups and field parameters would help students alike to identify when or when not to apply these.

Thank you for taking the time to read through my suggestion. I sincerely hope that it will be considered during a course update :)
