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, tblQuadrant, tblRegion, tblSpecies, tblStore, tblTown, tblTransaction.  Delete any measures already created.

The aim of this exercise is to create the following pivot table, showing average transaction price by quadrant:

The pivot table divides spending into South region and other regions.

To do this, create two measures:

Name What it shows
NoSoutherners Calculates the average price of transactions, but excluding the South region.
OnlySoutherners Does the same thing, but only for the South region.

You'll need to use the VALUES function, otherwise Excel will remove any constraint by quadrant, rather than modifying it.

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 Beautiful South, and save your workbook with the same file name.
