The answer to the exercise will be included and explained if you attend the course listed below!
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.
Import from this database the following tables:
The tables to import, so we can look at regions, towns, etc.
If you haven't already chosen only to import the columns you need, delete columns from your data model and hide others from client tools to get this pivot table field list:
Your data model should only expose these fields.
In PowerPivot Diagram View, you should have only 17 columns included, and many of these will be hidden from client tools.
Now create this simple pivot table:
A pivot table showing the total quantity of items sold, by region.
The figure of 1984 for London looks suspiciously Orwellian. Use Quick Explore (right-click on the cell for the menu option) to drill down to show that this is made up of these figures:
The first few towns for this region.
Repeat this process to show:
- the 773 figure for London town broken down by centre; then
- the 122 figure for Leyton Mills broken down by store.
You should now see this:
You can use CTRL + Z to undo what you've done until you're back at the original pivot table.
Impressive stuff! Now add a slicer to your pivot table, and use it to show only towns for regions in the East and/or West Midlands:
You don't have to apply the hideous style shown here, but you should make your slicer have 3 columns.
Finally, create another pivot table showing the average price of transactions by shopping centre, and get this to be controlled by the slicer shown above also:
Here's what this pivot table should show when you have the same regions (East and West Midlands) selected on the slicer on the other worksheet.
