Taking Blank Value from Date Column

Hi mohammadyousaf ,

Hope below is what you expected:

1. Create a rank measure:

Rank =
VAR _last =
    RANKX (
        ALLSELECTED ( 'Table' ),
        CALCULATE ( MAX ( ( 'Table'[Start Date] ) ) ),
        ,
        ASC,
        DENSE
    )
RETURN
    IF (
        MAX ( 'Table'[Finish Date] ) = BLANK (),
        MAXX ( ALLSELECTED ( 'Table' ), _last ) + 1,
        _last
    )

2. A measure for Card visual:

Measure = 
VAR _lastFinish =
    CALCULATE (
        MAX ( 'Table'[Finish Date] ),
        FILTER ( 'Table', [Rank] = MAXX ( ALL ( 'Table' ), [Rank] ) )
    )
VAR _ifinprogress =
    IF (
        _lastFinish = BLANK (),
        "In Progress",
        FORMAT ( _lastFinish, "m/dd/yyyy" )
    )
RETURN
    IF (
        ISFILTERED ( 'Table'[Name] ),
        IF (
            MAX ( 'Table'[Finish Date] ) = BLANK (),
            "N/A",
            FORMAT ( MAX ( 'Table'[Finish Date] ), "m/dd/yyyy" )
        ),
        _ifinprogress
    )
