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.
Open the Power BI file in the above folder. It shows the following matrix:
Sales by environment and centre type
Your task is to use the CALCULATE function in an expression to return the following measure:
With this in mind, create a new measure in the All measures table called All environment contribution, and change your matrix to display this:
Reassuringly, your environmental contributions should sum to 100% for each row.
Create and display another measure called Grand total contribution which shows the ratio of sales to sales for all environments and all centre types:
Again reassuringly your grand total should be 100%.
You need to use the ALL function twice, to remove the environment constraint and the centre type constraint.
Save this file as No constraints, then close it down.
