Jonathan Stewart: Translytical Task Flows: So Much More Than Write-Back

IN PERSON MEETING!!!!!
When was the last time a dashboard made you reach for your phone to film it? By the end of this 45-minute session, you will want to.
With Microsoft introducing Translytical Task Flows, Power BI now has a native Fabric-backed pattern for write-back. Update that row. Approve that line item. Override that forecast. These are all things we have wanted, and they are wonderful. If you are not using Translytical Task Flows for that, start Monday.
But there is more.
So much more.
That button connects to Fabric User Data Functions, and it is not just a write-back widget. It is serverless Python running directly in Fabric. You can pass report context and user input into governed business logic, access Fabric data sources through managed connections, inspect the verified caller’s identity metadata, call external APIs when appropriate, and do it without standing up a separate API server.
Write-back is just the beginning.
What happens when the button is not constrained to a table update?
What happens when it can reach past your warehouse, past your tenant, and into the systems and services your business actually runs on, while still answering the question of who clicked it?
That is what this session is about.
What you'll see, no spoilers:
One button in Power BI. Nothing pre-recorded. Nothing pre-canned. All live, in front of you.
We will end with a report doing something a report has no business doing.
Come see what happens.
Who it's for:
This session is for Power BI developers, Fabric data engineers, and BI architects who already use write-back, as well as those intrigued by the boundless possibilities of what Power BI can really do.
What you'll leave with — four reusable patterns and a sharper mental model:
- See the data-function button as an action surface, not a form.
- Reason about who clicked versus who actually runs the work.
- Gate an action on server-verified state, not on a hidden column.
- Know when a report should reach beyond Fabric, and how to keep that safe.
Write-back was the doorway.
Come see what is on the other side!
