๐ POWER BI TIPS FOR BEGINNERS โ PART 2 Learning Power BI becomes much easier when you understand not just what to use, but when and why to use it. ๐ 1. Define the business question first Before creating a visual, understand what decision the report needs to support. Don't build charts just because the data is available. ๐ 2. Create a proper Date Table A dedicated Date table makes time-based analysis such as YTD, MTD, QTD, and YoY much more reliable. ๐ 3. Name your measures clearly Use names like "Total Sales", "Total Profit", and "Profit Margin %" instead of confusing or automatically generated names. ๐ 4. Avoid unnecessary Many-to-Many relationships Use a clear dimensional model whenever possible. Many-to-Many relationships can make filtering and DAX more complicated. ๐ 5. Learn filter context before advanced DAX Understanding why a measure changes when you apply a slicer or filter is essential for mastering DAX. ๐ 6. Use "DIVIDE()" for ratios When calculating percentages or ratios, "DIVIDE()" provides safer handling when the denominator is zero or blank. ๐ 7. Keep your data model organized Use meaningful table and column names and keep your model easy to understand and maintain. ๐ 8. Use Performance Analyzer when a report feels slow Don't guess the problem. Identify which visuals or queries are taking the most time and investigate the actual bottleneck. ๐ 9. Test interactions between visuals Click different charts and slicers to make sure cross-filtering and highlighting behave as intended. ๐ 10. Build projects while learning Don't wait until you finish learning Power BI. Build Sales, HR, Finance, or Marketing dashboards as you learn each concept. ๐ Double Tap โค๏ธ For More
