With everyone getting their hands on CTP3, I decided to take a short break from the football project and show something else that may spark you to try things you otherwise might not.

So, let’s go behind the scenes of the Temperature Mashup example (that’s mentioned here and here).

Part One:

Part Two:

#### Recap

Briefly, here are the steps covered in the videos:

1. Copying the temperature data from Excel and pasting as a new table in PowerPivot
2. Using CONCATENATE to create “key” columns in both the Temperature and Sales tables
3. Creating a relationship between those tables, using the key columns created in 2
4. Demonstrating that the relationship enables slicing sales by temperature
5. Using a nested IF formula to add a new column to the Temperature table, mapping granular average temperature values into the four buckets Cold, Cool, Warm, Hot
6. Using that newly-calculated column to slice sales numbers instead

#### Next up…

Using DAX to create a “Sales per Day” measure!

Okay, now I finally see why you are so excited about this stuff. As somebody who doesn’t normally do BI… it was a bit hard to grasp the power, but that was crazy cool.

2. Great video Rob, i can show it to my non BI colleagues and managers to let them see what PowerPivot is all about. One quick question, will PowerPivot be translated to other languages as excel is too? The IF excel function is called ALS in my native tongue.

3. […] shows you a grand total of something, regardless of what filters are in play.  Revisiting the Temperature Mashup demo for a moment, here’s a pivot sliced by Temperature, showing a normal Sum of Order […]

Why have you not removed the “Grand Total” from the pivot table as it is meaningless in the context of “Average” and may confuse as it implies “SUM” is valid for different “items”.

1. Do you mean in this video or in another video? In the videos above, I think all of the measures are SUM, correct?

And while the “Grand Total” label itself may be misleading when the measures are an Average, it is quite often still a valid and useful number to see – the average of the entire data set (minus slicer filters of course).

Hi, powerpivotpro!

I noticed your website from CIMA e-mails. I think it is quite amazing. One of my career goal is to build a BI for a company and PowerPivot is just the tool I need!.

I have finished the two vedio above, however, where is the DAX? How can I find the 3 part?

Thanks!

Hi there Aden, thank you for the kind words

Not sure what you mean by part three, but:

youtube.com/powerpivotpro has all of my videos

most posts on this site deal with DAX.

i just finished a book on DAX, you might consider the eBook version (link in my most recent post)

6. Hi Rob,
Great resource. I didn’t realise that PowerPivot is such a great tool until three days ago.

I have one question in regards to the way you set up your measure “Qty per Day”. Do you think it would be a bit more informative to divide quantity by a number of days in each temperature range? My thinking is that overall you may have a lot of cool days for example(let’s say 50), but only sold anything on five days, whereas in 15 warm days that you had you sold on four. You can get a result saying that cool days are better for you business, than warm day, when if fact that would be a lie in real life.

Thanks for sharing your knowledge Rob!
