Adding a Calculated Column in Semantic Model
I am trying to replicate a power bi "desktop" model in a fabric lakehouse. I have a lakehouse with all the tables loaded and I've created a semantic model. I need to create some calculated column...
This is not currently supported for semantic models derived from a lakehouse.
Please see: Learn about Direct Lake in Power BI and Microsoft Fabric - Microsoft Fabric | Microsoft Learn
As an option, you can create them in your lakehouse.
No, I don't believe you can use DAX. I was thinking how ever you created your lakehouse, like if you used Gen2 dataflows, you could replicate the logic.
Hi JaviGolden, this feature is now supported with the April 2026 Power BI update, although still in preview.
Please check the Microsoft blog: Power BI April 2026 Feature Summary | Microsoft Power BI Blog | Microsoft Power BI
Hope this helped!
They did declare it but I do not see it available yet (even in PREVIEW mode)
