🚀 Power BI Interview Challenge #2 🔥

𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄𝗲𝗿:
You have 2 minutes to solve this Power BI problem.

You have a Sales table with the columns: Order Date & Sales

Create a DAX measure to calculate Month-to-Date (MTD) Sales.

𝗠𝗲: Challenge accepted! 💪
MTD Sales =
TOTALMTD(
SUM(Sales[Sales]),
Sales[Order Date]
)

💡 Explanation:
• TOTALMTD() calculates cumulative sales from the beginning of the current month up to the selected date.
• SUM(Sales) returns the total sales amount.
• Sales[Order Date] is the date column used for the MTD calculation.
• The measure automatically resets at the beginning of each new month.

🎯 Expected Output Example
Date | Sales | MTD Sales
Jul 1 | 2,000 | 2,000
Jul 2 | 3,500 | 5,500
Jul 3 | 1,500 | 7,000
Jul 4 | 4,000 | 11,000

🚀 Bonus (Using a Calendar Table)
MTD Sales =
TOTALMTD(
[Total Sales],
'Calendar'[Date]
)

Using a dedicated Calendar table improves model performance and ensures accurate time intelligence calculations.

🚀 Tip for Power BI Job Seekers:
Always create a proper Date Table and mark it as a Date Table in Power BI before using Time Intelligence functions. Many interview questions are designed to test this best practice.
