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.

Create a new Power BI Desktop file, and load the Excel workbook from the folder above. Use this to create a table showing the number of offences for each offence subgroup:

The first few rows of the table.

We want to be able to filter this to show only those offences for a particular group:

The offence groups. It would be nice to be able to type one of these into a parameter box, and see the table change!

In Query Editor, create a new parameter called OffenceGroup, and set its default value to Robbery (if for no other reason than that it's the shortest offence group name to type in!):

Your parameter should look something like this.

Still in Query Editor, filter the table of offences to show only those ones for the offence group specified by your parameter:

After returning to your report, you should now see your table is much shorter!

We could do with a title for our report. Go back to Query Editor, and tell Power BI Desktop that you want to load your parameter into your data model:

In Query Editor, choose to enable loading for your parameter.

Set the title of the visual to be an expression:

Click here to set the title to be the value of a field, then choose to show the first value of your parameter (it is of course also the only value of it!).

Your table should now display the offence group name as a title:
