PL-300 practice 8: high-value customers
The account team defines a high-value customer as one with at least 10,000 of sales in the period. They want the count per country and year.
The threshold applies per customer, in each cell.
Your task
Create High-Value Customers: the number of customers with a Sales Amount of at least 10,000 in the cell.
About this exercise
You practise exam-style task: segmentation with COUNTROWS, FILTER and VALUES. The exercise runs on a small bike-shop model with a Sales fact table and Product, Customer and Date dimensions, the same star schema in every lesson.
Your measure, High-Value Customers, fills a Power BI-style matrix grouped by Customer[Country] and Date[Year]. As in a real report, each cell evaluates the measure in its own filter context, and the subtotals and the grand total are evaluated again in theirs rather than added up. When you check your answer, every cell is compared with the expected value, wrong cells are marked, and the hint is about the mistake you made.
Measures that already exist in the model: Sales Amount. Reference them in square brackets, for example [Sales Amount].
