When Translytical Task Flow meets Fabric Data Function
Proposed session for SQLBits 2026TL; DR
See Translytical Task Flow in action: It combines Fabric User Data Functions (Python functions that can amongst others access and modify data) with Power BI actions to call them, and Power BI visuals that provide input to them.
Session Details
User Data Functions in Fabric are Python functions which you can write once and then reuse in different Fabric items. These functions can modify data, call web services, or just do complex calculations.
Once written, you can call these functions from Fabric Notebooks etc. But the most interesting use case is calling them from Power BI. A new type of action becomes available on buttons: Calling the Data Functions!
In this demo-rich session, you will first learn how to develop User Data Functions, both for transforming data as well as accessing data.
Afterwards you see how to invoke these user data functions in Fabric and how to link the with your Power BI reports.
