Help with calculating 3 months rolling average
I have below Matrix which is 3 different measures (only below 2 are important)
"Cash Out ACT SAP" = Costs month by month
"Cash Out YTD SAP" = Accumulated costs based on first column
I want to calculate a forecast that goes into the empty cell/cells for column "Cash Out YTD SAP"
I want to make a forecast base on the last 3 months from "Cash Out ACT SAP"
So, in order to populate 12/1/2023 for "Cash Out ACT SAP" I will take average of (9/1 + 10/1 + 11/1)/3
I then want to PLUS than on "Cash Out YTD SAP" 11/1 to populate 12/1
Maybe new columns should be made.
Have tried below but returns an error:
