🌟 SUMMARIZE vs SUMMARIZECOLUMNS in Power BI: Which One Should You Use? 🌟

When working in Power BI, sometimes you need to create summary tables to group your data or calculate totals. That’s where SUMMARIZE and SUMMARIZECOLUMNS come in! Both are used to summarize data, but they work in slightly different ways. Let’s break it down in simple terms.

1️⃣ SUMMARIZE: The All-RounderSUMMARIZE is like an old friend—reliable and flexible. It lets you group data by columns and even create extra calculated values in your table.
🔹 Example:
You want to see total sales grouped by region and category:
SUMMARIZE(Sales, Sales[Region], Sales[Category], "Total Sales", SUM(Sales[Amount]))
Here, you’re creating a table that shows regions, categories, and total sales.
💡 When to Use:
You want to group data AND create new calculated values at the same time.

2️⃣ SUMMARIZECOLUMNS: The Fast Performer
SUMMARIZECOLUMNS is newer and built for speed. It groups data just like SUMMARIZE, but it’s designed to work faster, especially with larger datasets. Plus, it automatically respects any filters applied to your data.
🔹 Example:
You want to see total sales grouped by region:
SUMMARIZECOLUMNS(Sales[Region], "Total Sales", SUM(Sales[Amount]))
This creates a summary table for regions and total sales, and it’s quicker if you’re working with lots of data.💡 When to Use:
You need better performance.
Your data already has filters applied, and you don’t want to add extra calculations.

💡Which One Should You Pick?
Use SUMMARIZE when you need flexibility to add new calculations to your table.
Use SUMMARIZECOLUMNS when speed and efficiency matter more, especially with large datasets.
Power BI is all about using the right tool for the job. Knowing when to use SUMMARIZE or SUMMARIZECOLUMNS can help you create faster, smarter dashboards that wow your audience! 🚀
