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.
To start, if you haven't already done so run the script in the above folder to generate the MAM database (not for commercial use or copying).
Create the following PowerPivot field list as a data model (or something similar to it):
You'll need to create two new calculated columns: one to give the year of each transaction, and one to give the amount (price times quantity).
The tables you'll need to import are tblAnimal, tblProduct, tblStore, tblTransaction, tblSpecies and tblPos.
Create and display a measure which gives the percentage contribution each cell (each filter context) makes to the total amount:
The reptile total for Arndale Centre - store A is 0.12% of the grand total, for example.
Select all of the species in the horizontal slicer, and scroll down to check that the grand total is now 100% for all stores, years and species (it should be).
