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 (copying and commercial use prohibited) to generate a database called MAM.  Also if you haven't already done so, run the spCreateCalendarTable stored procedure to create a calendar table.

Create a new workbook, and within this import the following tables:

Tables needed

The tables needed for our data model.

In these tables, create two new columns as shown called Region and Town, to give region and town names with a UK suffix.

Now use these two new columns to create the following map (in Power View, not Power Map), showing the number of transactions by town and region:

Transactions by town and region

The Region field is the vertical multiple, and we've applied a filter to show only towns having 5 or more stores.

Add the Town field to the Locations column so that you can double-click on a slice:

Reading transactions

Here we're showing all transactions for Reading.


This will then drill-down to show all of the transactions for this town:

Transactions for Reading - drill-down

You can undo this to return to the previous map.

Save this workbook as Did it crash though, and close it down.
