Power BI Weekly

Issue #323 - 2nd September 2025

A pretty quiet week all round - no announcements and only a handful of content. Here are the bits of content I'd like to highlight this week: firstly, Marcus Wegener has shared a PoC he put together to show the art of the possible around creating Portable Power BI Dashboard Templates with Fabric Notebooks PoC, whereby you create a "template" report with placeholder objects that are then remapped to target objects using sempy, which eventually spits out a report. A great efficiency boost for cookie-cutter reports that you can easily use configuration to rebind to a new model. Chris Webb has written a new version of a blog written a couple of years ago around Performance Testing Power BI Direct Lake Models: Ensuring Worst-Case Performance after some recent improvements to the Direct Lake engine have changed how this works. Finally, Reza Rad has provided us with a useful Microsoft Fabric Org App VS Power BI App comparison video, describing the key differences and the implications of the new "org app" approach from an architectural perspective.
