DAX ??? Help

[Syndicate_Admin]

Hi I have the data mentioned below and I wanted to create a New Val calculated column, as long as there is negative, make it zero and the record of the next row should subtract the negative values. In the following example, on 1/1/2025 role 2 has -25 and has to be zero in New Val and the next row which is role 3 val has 40, but New Val must 40-25, i.e. 15 must get it. I'm not sure how to create a calculated column to get values like the ones I described. Any help.

Hello @Syndicate_Admin 

You can try with below DAX for calculated column

New Val =

VAR CurrentIndex = 'Table'[Index]

VAR CurrentVal = 'Table'[Val]

VAR PrevVal =

    CALCULATE(

        MAX('Table'[Val]),

        FILTER(

            'Table',

            'Table'[Index] = CurrentIndex - 1

        )

    )

RETURN

    IF(

        CurrentVal < 0,

        0,

        IF(

            PrevVal < 0,

            CurrentVal + PrevVal,  -- because PrevVal is negative

            CurrentVal

        )

    )
