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.
The aim of this exercise is to show the total value of transactions according to the day of the week:
It looks like Friday was the most popular day, but not by much.
Here's what the PowerPivot field list should look like (eventually!):
The two fields of interest for our pivot table.
To start, if you haven't already done so run the script in the above folder to generate the MAM database (not for commercial use or copying), then create a new workbook.
Connect to the tblTransaction and tblPos tables, and create a new calculated column in the latter which gives the weekday.
You can use either =format([PosDate],"dddd") or =format(Pos[PosDate],"dddd"), depending on how you create the formula.
Now use the RELATED function in the tblTransaction table to show the weekday alongside the quantity sold, and use this to create the pivot table at the start of this exercise.
Your formula should start =RELATED(.
To get the pivot table to sort the days correctly, just sort by the day name:
Click on the row labels drop down and choose to sort A to Z. As to why this works - wait for the calendar part of the course!
Save this workbook as Daily sales, then close it down.
