Calculate the values between two lines within the same value in another column

[renanc]

Hi everybody, I have a calculated value on Dax, but it calculates the value between the current fuel fill and the next one. I want to calculate the value between the current fuel fill and the previous one. Can abybody help me with this, please?

The Dax formula used is here, and attachet below.

Thank you

Diferenca KM =

var _min =

CALCULATE(

FIRSTNONBLANK(fChecklists[IdChecklist],0),

FILTER(

ALL(fChecklists),

fChecklists[IdChecklist] > EARLIER([IdChecklist])

&& fChecklists[DescPlaca]=EARLIER([DescPlaca])

&& fChecklists[DtCadastro] >= EARLIER([DtCadastro])

&& fChecklists[IdQuestionario] = EARLIER([IdQuestionario])

)

)

return

CALCULATE(

MIN([Digite a KM]),

FILTER(

ALL(fChecklists),

fChecklists[IdChecklist] = _min

&& fChecklists[DescPlaca]=EARLIER([DescPlaca])

&& fChecklists[IdQuestionario] = EARLIER([IdQuestionario])

)

) - [Digite a KM]

HI @renanc,

You can try to use the following formula if helps: (I try to lookup the previous date based on the current place and date)

Diferenca KM =
VAR _prevDate =
    CALCULATE (
        MAX ( fChecklists[Date] ),
        FILTER (
            fChecklists,
            fChecklists[Date] < EARLIER ( fChecklists[Date] )
                && fChecklists[DescPlaca] = EARLIER ( [DescPlaca] )
                && [Digite a KM] <> BLANK ()
        )
    )
RETURN
    CALCULATE (
        SUM ( [Digite a KM] ),
        FILTER (
            fChecklists,
            fChecklists[Date] = _prevDate
                && fChecklists[DescPlaca] = EARLIER ( [DescPlaca] )
        )
    ) - fChecklists[Digite a KM]
