Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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, run the SQL script in the above folder in SQL Server Management Studio to generate a database (not for commercial use or copying) called MAM

Again if you haven't already done so, create a new project called BaseModel, and import the following tables: tblAnimal, tblCentre, tblCentreType, tblPos, tblProduct, tlbQuandrant, tblRegion, tblSpecies, tblStore, tblTown, tblTransaction

Use the CALCULATE function to create the following measures:

Name What it shows
Total Qty The total quantity of goods sold for the current filter context
QuadPercent The percentage this constitutes of the total for quadrupeds

You should now be able to show the following pivot table:

The pivot table shows the total quantity sold for each cell's filter context, together witih the percentage this constitutes of the total for four-legged animals.

Now create (and show in your pivot table) another measure which shows [total sales for the current filter context] as a percentage of [total sales for the current filter context, but for all leg types]:

Reassuringly, the total for any quadrant is 100%. Quadrupeds constitute just over half the total for each quadrant.

If you want to keep a copy of what you've done, use DAX Editor to create a copy of your measures with extension .dax called Four legs good, and save your workbook with the same file name.
