This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
This will generate the database that you'll need to use in order to do this exercise (note that the database and script are only to be used for exercises published on this website, and may not be reused or distributed in any form without the prior written permission of Wise Owl).
If you haven't already done so, create a new project called BaseModel, and import the following tables: Centre, CentreType, Environment, Family, Habitat, Product, Purchase, Region and Town.
Use the CALCULATE function to create the following measures:
|Name||What it shows|
|Total Qty||The total quantity of goods sold for the current filter context|
|Share of all families||The percentage this constitutes of the total for all families|
You should now be able to show the following pivot table:
The percentages sum to 100, which is a relief - they should.
Now create another measure called Share all F and E to show each pivot table cell's contribution towards the total sales for all families and all environments, and use this to show this pivot table:
Again, it's a relief that the grand total is 100% for this pivot table.
Now create (and show in your pivot table) another measure called Mammal share which shows [total sales for the current filter context] as a percentage of [total sales for the current filter context, but for mammals]:
The Air column displays errors because the denominator is 0 (they're aren't any bats in our database!).
If you're feeling adventurous, use the IFERROR function to display blanks where your measure would otherwise return an error (or - perhaps better - use the DIVIDE function instead).
Save your workbook as No bats, then close it down.
