    In that case, you can select the relevant columns first from both tables using "SELECTCOLUMNS" function

    Then apply the above procedure

     

    i.e.

     

    Calculated Table =
VAR firstTable =
    SELECTCOLUMNS ( Table1, "ID", [ID], "Serial", [Serial], "Name", [Name] )
VAR SecondTable =
    SELECTCOLUMNS ( Table2, "ID", [ID], "Serial", [Serial], "Name", [Name] )
VAR Common =
    INTERSECT ( firstTable, SecondTable )
VAR NotCommon =
    EXCEPT ( DISTINCT ( UNION ( firstTable, SecondTable ) ), Common )
RETURN
    UNION (
        ADDCOLUMNS ( Common, "Unique", "No" ),
        ADDCOLUMNS ( NotCommon, "Unique", "Yes" )
    )

Syukron, Zubair_Muhammad It almost there ..

But I've 2 more question related to this if you are OK 

 

Current DAX, both variable that compared but how to find unique only from 1 column e.g. Serial Number from both table

The result now have "null" but unable to get in query mode to remove this null . Unable relate the data by having null
