Question 260
A Power BI team has selected this approach: Use SUMX over order lines to sum Quantity multiplied by UnitPrice. The original business context is: A model has one row per order line with Quantity and UnitPrice but no stored line amount. What validation would be most relevant before accepting this change?
Explanation
Correct Answer
A multi-line invoice total matches the arithmetic of each line extended price. It provides the required observation for the chosen implementation: Use SUMX over order lines to sum Quantity multiplied by UnitPrice. This test addresses the stated business constraint directly.
Incorrect Answers
Rows fall into exactly one configured bucket and the field appears in the slicer. That check would be meaningful for the separate case: A table needs a labeled categorical bucket for each static Amount value to support a slicer. It would not directly verify this scenario's selected implementation: Use SUMX over order lines to sum Quantity multiplied by UnitPrice.
Sales and Margin both respond to the same calculation item without duplicating separate measures. That check would be meaningful for the separate case: A calculation group should apply a shared Previous Year transformation to several explicit measures. It would not directly verify this scenario's selected implementation: Use SUMX over order lines to sum Quantity multiplied by UnitPrice.
The highest-selling visible product ranks first within the selected brand scope. That check would be meaningful for the separate case: A rank indicator must rank products by Total Sales among the currently selected brands. It would not directly verify this scenario's selected implementation: Use SUMX over order lines to sum Quantity multiplied by UnitPrice.
