Calculate the previous within the same information

Hi everybody,

I am trying to calculate the previous KM for the same car plate.
I tried a Dax Formula to calculate the previous value, but it actually returns the value for the next Checklist. I tried to modify the operators, and also tried LASTNORBLANK instead of FIRSTNONBLANK, but it didn't give me the expected values..

Can anybody help me with this, please?

Thank you

KM Anterior =
CALCULATE(
FIRSTNONBLANK(fChecklists[Digite a KM],1),
FILTER(
ALL(fChecklists),
(fChecklists[DescPlaca])=EARLIER(fChecklists[DescPlaca])
&& fChecklists[IdChecklist] > EARLIER(fChecklists[IdChecklist])
&& fChecklists[IdQuestionario] = EARLIER([IdQuestionario])
&& fChecklists[DtCadastro] >= EARLIER([DtCadastro])
)
)
