Rolling Period Calculations

[bcharlto]

I am looking to add rolling 12wk timeframes to my dataset. I want to be able to look at 104 weeks of data by week and then smooth it out so that each week is an average of the previous 12wks. I have only seen posts tied to calculations based on the most recent week. I am not looking to calculate L12wk sales. Are there any suggestions?

Once I grasp this, I'm also looking to calculate a rolling 12wk Max Price over 104wks of sales...

I am working with retail POS data that is weekly store level, product level.

I'm not sure it can be done...

It is absolutely possible. I do this as a 3 month average as well as a 16 week average. I used the information from this post to complete my calculations.

Remember, most of what works in PowerPivot works in PowerBI as well.
