PL-300 practice 4: growth versus last year
The sales director compares countries by growth: this year against last year, in percent. 2024 is the first year of data and must stay empty.
Use variables for this year and last year, and DIVIDE for the result.
Your task
Create Growth %: (Sales Amount minus last year’s Sales Amount) divided by last year’s Sales Amount.
About this exercise
You practise exam-style task: sameperiodlastyear with SAMEPERIODLASTYEAR, DIVIDE and VAR. 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, Growth %, 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].
