Create a new workbook, and import the following tables into a new PowerPivot data model:

As ever, give your tables friendly names too.

Create a pivot table based on this model, showing total quantity sold by family and centre type:

A vanilla pivot table!

Create a measure to show in each cell total sales for that centre type and that family, divided by total sales for that centre type for all families.  The numerator can just show total sales:

=SUM ( [Quantity] )

The denominator will be more complicated:

=SUM( [Quantity] ) / CALCULATE ( SUM ( [Quantity] ), ALL ( ... ) )

The resulting pivot table should look like this:

You can actually do this in normal Excel pivot tables too, although PowerPivot will let you create much more complicated measures than this.

Feeling flushed with success?  Try creating and showing another measure, this time to show sales as a percentage of all centre types:

This time it's the bottom total which shows 100% for each cell.

Save this workbook as Fair shares, then close it down.
