    Green_G  you can write a measure like this

    Measure2 = 
//what is the min event # by REF
VAR one =
    CALCULATE (
        MIN ( 'Table 1'[EVENT_NO] ),
        ALL ( 'Table 1' ),
        VALUES ( 'Table 1'[REF] )
    ) // what is the source when event = one by ref
VAR two =
    CALCULATE (
        MIN ( 'Table 1'[SOURCE] ),
        FILTER (
            ALL ( 'Table 1' ),
            'Table 1'[EVENT_NO] = one
                && 'Table 1'[REF] = MAX ( 'Table 1'[REF] )
        )
    )
RETURN
    two
