Power BI Weekly
Issue #327 - 30th September 2025
As ever, a slightly quieter week after the excitement of FabCon. However, you'll find a few reflective blogs about it this week, and naturally I think you should take a look at my colleague Carmel's FabCon Vienna 2025: Day 1 breakdown, which is soon to be followed by Day 2 & 3. Great if you'd like a non-MSFT breakdown of the announcements and highlights from the conference. I also realised I missed the official DAX UDFs: Code once, reuse everywhere (Preview) blog last week, though there were plenty of other bits of content about UDFs that you probably saw. Onto the highlighted articles this week: Zoe Douglas has written about a feature of semantic models I didn't actually know about: KPIs. There's no way to create these directly through the Power BI Desktop UI, but you can use the TMDL view as Zoe explains. Very cool. Elsewhere, Phil Seamark has shared a write-up of a presentation of his, describing how to Create Custom Visuals in Power BI with GitHub Copilot. If you want a bit of a fun read about weird and wacky things you can do with Power BI custom visuals, then look no further!
