    =
VAR SourceN =
    SWITCH (
        SELECTEDVALUE ( TableName[CountryName] ),
        "A", "X",
        "B", "X",
        "C", "Z"

Thanks for replying. Now when I select particular country in filter I am getting required answer. But how to get deafult condition which is  to calculate distinctcount(customer code) when all the countries 'A','B','C' are selected in the filter.  I am strucked at this point now.

I believe this should be fully dynamic therefore no need for default value.

=
VAR SourceN =
    SELECTCOLUMNS (
        VALUES ( TableName[CountryName] ),
        "@Country", SWITCH ( TableName[CountryName], "A", "X", "B", "X", "C", "Z" )
    )
RETURN
    CALCULATE (
        DISTINCTCOUNT ( TableName[customercode] ),
        TableName[SourceName] IN SourceN
    )

    tamerj1 Thank you again for answering. This is not working. It is giving answer only when country name = "B" and even that answer to is wrong.
