Power BI Weekly

Issue #329 - 14th October 2025

This week, we've had a few official articles. First of all, the "Prep Your Data for AI" feature is Now in the Power BI Service, meaning you don't need to switch tools if you're already working in Fabric. Microsoft is also now Empowering its customers to shape the future of data connectivity in Power BI and Microsoft Fabric by committing to drive their Power Query / Data Factory connector backlog based on ideas and votes by the community. Finally, the Power BI Report Server September 2025 Feature Summary, with a handful of visualisation & reporting updates, alongside highlighting that all on-premises reporting servises are being consolidated under Power BI Report Server as of SQL Server 2025. Over on the Fabric side, but still related to Power BI: we now have Service Principal Support in Semantic Link, so now notebooks can be automated without having to use your own credentials. And, presumably, you can automate some Admin workloads without having to be a permanent admin yourself.

Elsewhere this week, Philipp Lenz has shared a snippet to create a Power BI Date table in TMDL, Chris Webb has written an interesting article taking a First Look At Fabric Graph: Analysing Power BI Import Mode Refresh Job Graphs, and Carmel is back with her write-up of FabCon Vienna 2025: Day 2 and Day 3. Oh, and finally, my colleague Barry attended Big Data LDN 2025 - the hugely popular (free-to-attend) Data and AI conference that takes place in London every September. This year was dominated by AI agents, with speakers quick to highlight what amazing things their org was doing with AI. Barry has now attended 5 years on the trot and analysed the trend over that time and has some interesting insights - be sure to give his blog a read.
