Calculate and Store Rolling Total in DAX

[Anonymous]

Hello all,

I'm trying to calculate a rolling sum over a 5 day time period and store that sum for each date in my table. I've created a sample data set that shows the relevant calculations in excel. I have tried to implement a rolling total using multiple online sources, but nothing seems to work. I have successfully created the 'All Lots [lbs]' column to total the smaller values, but cannot figure out the rolling sum. Due to other calculation constraints, I must do this calculation with DAX, not PowerQuery M. I would greatly appreciate any help!

(*) is used here as a placeholder, nothing more.

Hi @Anonymous ,

I have created a simple sample, please refer to it to see if it helps you.

Create 2 columns.

all lots = 'Table'[Lot 1]+'Table'[Lot 2]+'Table'[Lot 3]

5 day rolling total =
VAR _5day = 'Table'[date] + 4
RETURN
    CALCULATE (
        SUM ( 'Table'[all lots] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[date] <= _5day
                && 'Table'[date] >= EARLIER ( 'Table'[date] )
        )
    )

Best Regards
