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.
You can learn how to do this exercise on the relevant Wise Owl classroom training course (sadly for the moment only in the UK).
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 (copying and commercial use prohibited) to generate a database called MAM. Also if you haven't already done so, run the spCreateCalendarTable stored procedure to create a calendar table.
In a new workbook, create a suitable data model, and from this create a pivot table showing total quantities sold by year/quarter and quadrant:
You'll need to import the tables tblCalendar, tblCentre, tblPos, tblQuadrant, tblRegion, tblStore, tblTown and tblTransaction!
Create two new calculated fields as follows:
|Name||What it calculates|
|Same period last year||Total quantity sold for the same period in the previous year, using the SAMEPERIODLASTYEAR function.|
|Two quarters ago||Total quantity sold for the corresponding dates two quarters ago, using DATEADD.|
Show these in your pivot table:
Check back to the original pivot table in the exercise - you should satisfy yourself that the figures shown are correct.
Save this workbook as Annus horribilis, then close it down.
