Choosing the right data type in Power BI can make or break your financial reports. That’s why my latest YouTube video dives into the Currency vs. Decimal debate, helping you avoid mistakes, improve accuracy, and boost performance.
Why It’s Important
Whether you’re working with sales data, exchange rates, or massive datasets, the right data type matters. For instance, did you know that using Currency for exchange rates can lead to errors due to its 4-decimal limitation? Or that switching from Decimal to Currency can save memory in large datasets?
What’s in the Video?
In this tutorial, I break down:
- When to use Currency and when to choose Decimal for financial data.
- How tiny cumulative errors in exchange rates can lead to big discrepancies.
- Why too much precision can cause equality comparison issues in DAX.
- How the choice of data type impacts storage size and performance.
