Calculate the values between two lines

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 @Anonymous I found the solution for this case, it was:

KM Anterior =
VAR Ultimo_Checklist =
CALCULATE(
MAX(fChecklists2[IdChecklist]),
FILTER(
ALL(fChecklists2),
(fChecklists2[DescPlaca])=EARLIER([DescPlaca])
&& fChecklists2[IdChecklist] < EARLIER([IdChecklist])
&& fChecklists2[IdQuestionario] = EARLIER([IdQuestionario])
&& fChecklists2[DtCadastro] <= EARLIER([DtCadastro])
)
)

VAR KM_Anterior =
CALCULATE(
MAX(fChecklists2[Digite a KM]),
FILTER(
ALL(fChecklists2),
fChecklists2[IdChecklist] = Ultimo_Checklist
)
)

RETURN
KM_Anterior

Hi @renanc ,

 

Please share some sample data so that we could test the formula on it.

 

Best Regards,

Hi @johnt75, actually it did not work. In the new column (Diferenca KM 2), the values are negative values of those we have in Digite a KM.  Probably the term inside 

CALCULATE (
        MIN ( [Digite a KM] ),
        FILTER (
            ALL ( fChecklists ),
            fChecklists[IdChecklist] = _max
                && fChecklists[DescPlaca] = EARLIER ( [DescPlaca] )
                && fChecklists[IdQuestionario] = EARLIER ( [IdQuestionario] )
        )

is returning 0 or a null value, and then subtracting [Digite a KM].

Thank you for your help

You can try

Diferenca KM =
VAR _max =
    CALCULATE (
        LASTNONBLANK ( 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] = _max
                && fChecklists[DescPlaca] = EARLIER ( [DescPlaca] )
                && fChecklists[IdQuestionario] = EARLIER ( [IdQuestionario] )
        )
    ) - [Digite a KM]
