3 months average of historical sales the year before
Hi,
I need to calculate the three months average based on the historical sales data the year before.
For ex: Jan 20 Feb 20 Mar 20 - Average values should go under Jan 21.
100,0,100 - 66.7 Jan 21 value
Please could you suggest the optimal solution for the same? I have attached the screenshots for reference

Hi @ChrisAHeathcote ,
I got the logic. 12-9 = 3 which gives the average for 3 months including the current period(Jan 21 value - Jan 21, Jan20, Feb20,)
Thank you so much, Chris

Try using MOVINGSUM setting the start period as -12, end period -9 and AVERAGE keyword.

Hi @ChrisAHeathcote ,
I think the end period instead of -9 should be -10 then values would be right I guess. The test forecast is the line item that has an end period as -9 and the test line item has -10 as end period
Also if you could help me understand the behaviour of the end period.
Thank you

The start and end dates refer to the relative difference from the time period from which to calculate the aggregation.
-12 would be 12 time periods offset and -9 9 time periods.

So the value for Jan 21 would include Jan20, Feb20 and Mar20.
