Open the Power BI file in the above folder, and go to the Product table if it's not already visible on screen:
We'll add 3 calculated columns to this table.
Use the SUMX function to add the following calculated columns to this table:
|Total sales||The total sales across the entire database|
|Sales for product||The total sales for this product|
|Product contribution||The second column divided by the first|
