You have a Microsoft Excel 2016 workbook that has a Power Pivot model. The model contains the following tables:
* Product (Product_id, Producct_Name)
* Sales (Order_id, Order_Date, Product_id, Selasperson_id, Sales_Amount)
* Salesperson (Salesperson_id, Salesperson_name, address)
The model has the following relationships:
* Sales to Product
* Sales to Salesperson
You create a new Power BI file and import the Power Pivot model.
You need to ensure that you can generate a report that displays the count of products sold by each salesperson.
What should you do before you create the report?
