You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
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|
You'll have to use context transition for the second column (but you knew that anyway ...).
Here's what your final table should look like:
The final table - Sammy the Snake is clearly the leading contributor to sales.
Save this file as Context transition is fun, then close it down.
