Excel - Get & Transform (Power Query) - Moving average on M Code - Help on how to do it

Hi, All

 

I am trying to do a moving average on Excel Get and Transform, but I can't make it work.

Here is an example of the data.

item, month have a particular value; each item has multiple months.

The goal would  be to use some group by item and calculate moving average (say 3 months) per item.

 

I tried added an index and do {index}-1 thing, but I can't make it to work given the groupby contraint. I am looking for M code solution as I am doing some clean up.

 

Thanks for lending a hand here! 🙂 let me know any questions. Thanks!
