In this writing, I want to share how I started to learn using the Power BI Modeling MCP server  together with Power BI Projects (.pbip) and VSCode , and how that experiment turned into a full workflow: building a Contoso  star schema with an AI agent, generating a measure table , cleaning up metadata  (Sort by column), and automatically hiding visual-level filters  in the filter pane by editing the report JSON. This is all from an actual hands-on session; the screenshots I’ll

In this writing, I’d like to share the small experiment I did recently: querying an SVG measure from a semantic model using a Fabric Notebook , scaling it with Python, and displaying it directly in the notebook output. The idea started from a question from my manager: “If the semantic model produces SVG via DAX, can we render it outside Power BI and reuse it somewhere else?” Once I tried it, new use cases started to appear. The Data Model I Used Below is the sample semantic m

In this writing, I’d like to share how I started learning and experimenting with Copilot and AI-driven features  in Power BI and Fabric — and what I discovered about the role of semantic models  in making them work effectively. Prerequisites Before jumping into it, here’s the setup I used for experimenting with Copilot and AI-driven insights in Power BI and Fabric. Power BI Service (Fabric workspace)  — The experiments were all performed in a Fabric-enabled workspace, since C

In this writing, I’d like to share how I started to learn and create my own DAX UDF (User Defined Function) library , the pain points I’ve faced while trying to make the functions as general as possible, and how I plan to take the next steps forward. You can explore the project here: jihwankimdata/dax_udf_library How It Started Like many Power BI developers, I’ve written the same logic dozens of times — percentage growth, variance analysis, ranking, or window calculations — s

Introduction DAX User Defined Functions (UDFs) – introduced in the Power BI September 2025 release – let you encapsulate complex logic into named, parameterized functions that can be reused across measures and models. Power BI September 2025 Feature Summary | Microsoft Power BI Blog | Microsoft Power BI Unlike calculation groups, UDFs accept parameters and nest other functions, paving the way for cleaner, more maintainable semantic models. Enterprise scenario:  Let's assume,
