🌟 Power BI: Making Sense of ALL, ALLSELECTED, and ALLEXCEPT 🌟

If you have worked with DAX in Power BI, you have probably come across ALL, ALLSELECTED, and ALLEXCEPT. While they may sound similar, each serves a unique purpose in helping you analyze Data more effectively. Let’s break it down in simple terms! 😊

1️⃣ ALL: Ignoring Filters Completely
Think of ALL as the “see everything” button. It removes all filters from a specific column or table, letting you calculate totals or benchmarks without being influenced by slicers or filters.
🛠 Example Use: You want to show total sales across all regions, even if the user has selected just one region.

2️⃣ ALLSELECTED: Respecting User ChoicesThis is your “go-with-the-flow” function. ALLSELECTED considers filters the user has applied (like slicers), but ignores other filters like those from visuals. It’s perfect for dynamic calculations based on what the user has selected.
🛠 Example Use: You want to calculate how much a selected region contributes to the total sales for all regions visible on the dashboard.

3️⃣ ALLEXCEPT: Keeping What Matters
With ALLEXCEPT, you can remove filters but keep the ones you care about. This is great when you want to focus on one part of the Data without losing its context.
🛠 Example Use: You want to show sales by product but ignore filters for region or date.

Which One Should You Use?
Use ALL when you need to look at the bigger picture.
Use ALLSELECTED when you want to respect what the user has chosen.
Use ALLEXCEPT when you need to zoom in on specific details while ignoring the rest.

Power BI’s DAX functions like these let you control Data at a granular level, making your dashboards not just informative but interactive and insightful!
