POWERPIVOT 2010 EXERCISES
Exercise: Use EARLIER function to show number of previous joiners
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.
The answer to the exercise will be included and explained if you attend the course listed below!
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.
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).
Use the EARLIER function (it's in the manual!) to show the number of members of staff for each person who joined before that person did:
For example, 238 people joined before Gladstone Small.
Sort by date joined (A-Z and then Z-A) to check that:
- Akhlaq Aliyu (who joined first, on 10th May 1967) has 0 as the number of previous joiners; and
- Naeem O'Comain (who joined last, on 17th December 2008) has 2,279 previous joiners.
Too easy? Try creating another calculated column, and use sorting to show that Bob Cratchitt manages more staff than anyone else:
You'll need to add the ManagerId column to your table.
Self-referential calculations: don't you just love them! Save this workbook as Headspin, then close it down.
