Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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.

If you haven't already done so, run the SQL script in the above folder in SQL Server Management Studio to generate a database (not for commercial use or copying) called MAM

Create a new project and model, and import the tblCalendar, tblPos and tblTransaction tables.  Create the necessary relationship to link the Calendar and Pos tables, and make the calendar table a date table.

See how many of the following measures you can create (this pivot table is just showing data for 2014):

Pivot table

See the next page for hints!

Here are the measures that you need to create:

Measure Hints/notes
Total qty The total quantity sold for the current query context.
Last year total Use the PARALLELPERIOD function to calculate the total quantity sold for the whole of the previous year.
PercentLastYear Divide the [Total qty] measure by the [Last year total] one, using IFERROR to return BLANK if there's a problem (otherwise 2013 figures will return a divide-by-zero error).
YearToDate Use the TOTALYTD function to calculate year-to-date sales.
LastYearYTD Use a combination of the SAMEPERIODLASTYEAR and DATESYTD functions to calculate the year-to-date figures for the equivalent period in the previous year.

If you want to keep a copy of what you've done, use DAX Editor to create a copy of your measures with extension .dax called Wow, and save your workbook with the same file name.
