The Power BI Expert Is GONE. Now What?
Learn how Copilot for Power BI semantic models helps you understand existing business logic, document measures, and safely extend models when the original developer isn't available.
Every Power BI semantic model contains critical business knowledge, calculations, and assumptions that are often locked inside the head of the person who built it. This walkthrough follows a real-world scenario where a report owner needs to update an executive dashboard without access to the original model author.
You'll see how Copilot can explain revenue calculations, identify important measures, generate measure descriptions, and help validate whether existing model structures can answer new business questions before creating additional DAX.
Rather than focusing solely on code generation, this video highlights how Copilot accelerates semantic model understanding, improves documentation, and supports better long-term data governance practices.
Whether you're a Power BI analyst, semantic model owner, or Fabric professional, you'll discover practical ways to reduce dependency on institutional knowledge and maintain production-ready models with greater confidence.
