    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" )
    )

Hi __zhe,

 

Please new a calculated table and add a calculated column in it.

Table_3 = UNION(Table_1,Table_2)

Unique = IF(CALCULATE(COUNT(Table_3[Serial ]),ALLEXCEPT(Table_3,Table_3[Serial ]))>1,"No","Yes")

 

Best regards,

    Hi __zhe,

     

    table 1 & 2 have different structure, forgotten to mention in the example and also how to nood include null value

    As Zubair_Muhammad mentioned in previous reply, you can use SELECTCOLUMNS to deal with this problem.
