Power BI | Quick measures exercise | Changing and unchanging totals
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.
The answer to the exercise will be included and explained if you attend one of more of the courses 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.
Use the above file to create a table holding the total RuntTimeMinutes for each Certificate:
The total at the bottom is the grand total for all Certificates without any filtering. Future comparisons need to be made against that value.
As soon as a slicer or filter is added that total will be modified. To prevent that from happening create a quick measure:
This measure will come in handy when comparing sales to total sales.
Now create a second measure dividing the RunTimeMinutes by the new total measure that was created. Add both to the table visual:
Make sure the column names are explicit - you don't want report consumers to make false assumptions!
Repeat this process for Total for category (filters applied) and then apply a filter excluding certificate U:
Together quick measures and filters allow a huge range of calculations.
Optionally save this as Can't be censored and close it down.
