Hai All , Can you help me to rectify this dax error.

Please try

Version Month Selection Flag =
VAR SelectedTable =
    ALLSELECTED ( 'T1 Data Base' )
VAR Maxversion =
    MAXX ( SelectedTable, 'T1 Data Base'[Version Flag] )
VAR Mindate =
    MINX (
        FILTER ( SelectedTable, 'T1 Data Base'[Version Flag] = Maxversion ),
        'T1 Data Base'[Attribute]
    )
RETURN
    IF ( MAX ( 'T1 Data Base'[Attribute] ) >= Mindate, 1, 0 )
