Introduction to DAX User Defined Functions (UDFs)

We are very happy to invite you to a special in-person Berlin Power BI User Group meetup at TD Reply HQ.

This time, we will be joined by Marco Russo from SQLBI on an exclusive session on DAX User Defined Functions (UDFs).

A user-defined function is a DAX formula with parameters that can return values or tables, with parameters passed either by value or by expression. In this session, Marco will show how to define and consume user-defined functions in your semantic model, how to share them across different models, and how to use function libraries created by the community.

If you work with Power BI, Microsoft Fabric, semantic models, or DAX, this is a great chance to learn directly from one of the leading experts in the field. Marco Russo is co-author of The Definitive Guide to DAX and one of the best-known voices in the global Power BI community.

We will open the doors from 18:00, so there will be time to arrive, grab some food and drinks, and connect with other people from the Berlin data community before the session starts.

As a bonus, participants will also receive a discount coupon code for the Mastering DAX Workshop Berlin taking place on June 15–17, 2026.
