How to express this in DAX

[JustinDoh1]

I am trying to express this condition in DAX.

Table.ImmunizationDate > Table.ConsentDate

They are located in different row context (different row).

But, both have common which is Step = 1

However, to distinguish two better,

ImmunizationDate has "Historical" as Consent

ConsentDate has "Refused" as Consent

Hey @JustinDoh1 ,

I'm not really sure how the result should look like. I just guessed you want to return a 1 if Table.ImmunizationDate > Table.ConsentDate and a 0 if not.

Try the following measure:

Immunization after Consent =
VAR vImmunization =
    CALCULATE(
        MAX( myTable[ImmunizationDate] ),
        ALLEXCEPT(
            myTable,
            myTable[Step]
        )
    )
VAR vConsent =
    CALCULATE(
        MAX( myTable[ConsentDate] ),
        ALLEXCEPT(
            myTable,
            myTable[Step]
        )
    )
RETURN
    IF(
        vImmunization > vConsent,
        1,
        0
    )

If you need any help please let me know.
