I am working my way through the Alteryx Challenges as I am learning Alteryx. Here is my solution to the problem.

Started the workflow by transposing the data columns then I proceeded to apply the following treatments:

- sorted it ascending by RM Category, Year and Month

- Replaced Null() values with with the value on the previous row

- Used a Multi-Row Formula for creating the 3 months average, respectively the 6-month one

Ok Terrific

Seems a bit silly to put a Spoiler tag on it when the original post is 8 years old... 

 

I didn't pivot it all back into column to match the output because that also struck me as silly.

I got most of the way, but had to peek to get it right. 🙄

Great use of Multi-Row formula tools. 

 

It's weird that the problem is giving you a hint:  "For Values that do not exist, set values to closest valid row. " But the solution actually does not do that. It uses a zero for nulls instead. So I followed the hint and my response is slightly different from the solution. 

 

 I definitely learned that you can change the Num Rows in the Multi-Row Formula tool to play with a bigger selection of row, rather than the default 2. 

 

I also used the Average( ) formula rather than adding and then dividing by 3 or 6...should do the same thing theoretically :)

 

I also didn't do the last transpose as I liked how my table looked better. It doesn't make sense to me to put the RM Category as a Value. What was the reason for that?

Question is framed interestingly, and answer is not what is requested.

 

I've gone with a benefit of the doubt approach
