How do I express this in DAX? (where we have to filter multiple columns using same ID)

I have a scenario where I would like to use COUNTROWS to make a case of an existed case (as 1) so I could use in criteria inside SWTICH function clause.

I would like this to be case (Countrows as 1) when all these conditions are met:

1) ClientID is same

2) Step is same

3) ImmunizationDate (6/18/2021) for Consent as "Historical" > ConsentDate (5/21/2021) for Consent as "Refused" 

 

Appreciated for help!

I'm not positive how you'd like to handle all possible edge cases but I think this should get you started:

 

CountClientSteps =
VAR Summary =
    ADDCOLUMNS (
        SUMMARIZE ( Table1, Table1[ClientID], Table1[Step] ),
        "RefusedDate",
            CALCULATE ( MAX ( Table1[ConsentDate] ), Table1[Consent] = "Refused" ),
        "ImmunizedDate",
            CALCULATE ( MAX ( Table1[ImmunizationDate] ), Table1[Consent] = "Historical" )
    )
RETURN
    COUNTROWS ( FILTER ( Summary, [ImmunizedDate] > [RefusedDate] ) )
