Week 17: Can you build an automated monthly report

A few weeks ago I had this problem: I needed to create a dynamic table that showed the last 12 full months of sales for a particular channel/category of the business but I also needed to show the month-over-month and year-over-year totals. I didn’t know how to do it right away so I asked the Workout Wednesday team and they responded with many solutions. So I changed this week to match that exact problem. I’m also including some information on financial reporting since I wasn’t familiar until recently. We’ll be calculating basis points. The basic formula is (%a -%b)*10000. Where a and b are just two percentages. This means 1 bps = 0.01% and 100 bps = 1.00%.

  • Format: 1100px by 400px
  • Create a table that shows the following metrics for the last 12 full months by category:
    • Percent of total sales that are from the Consumer segment.
    • Month-over-month change in % Consumer sales using basis points (bps). (Current Month % – Prior Month %) * 10000
    • Year-over-year change in % Consumer sales using basis points (bps). (Current Month % – Same month prior year %) * 10000
  • Add a filter so that you can toggle dates. Note the months will only show when data is for a complete month of data.
  • Match formatting border and fill formatting.
  • ├ and └ will be useful.


    This week uses the superstore dataset for Tableau 2019.1.  You can get it here at data.world
