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.
If you haven't already done so, create the Make-a-Mammal database by running the SQL script in the above folder.
Create a new Power BI file, and load the following tables:
The tables you'll need to load to do this exercise.
Create a relationship between the tblCalendar and tblPurchase tables:
The relationship you should create.
The ultimate aim of this exercise is to create the following table:
Lots of help follows!
To do this, you'll need to create measures for the last 3 columns, using the guidance notes below:
|YearToDate||Count the cumulative year-to-date number of purchases, using either the TOTALYTD function or the CALCULATE and DATESYTD functions combined.|
|PreviousMonth||Use the CALCULATE function to count the number of purchases, with the PARALLELPERIOD function to change the filter context to the dates for the previous month.|
|CumulativeRatio||Divide the first measure by the second!|
You'll also need to filter your table to show only figures for January 2016.
Save this file as Last month, then close down the Power BI instance that you're using.
