    This is the code for a calculated column

     

    Any Differences? = 
VAR DistinctRows =
    COUNTROWS (
        DISTINCT (
            CALCULATETABLE (
                SELECTCOLUMNS (
                    'Employee Data',
                    "@Name", [Name], "@CC", [CC], "@EntryDate", [Entry date], "@LeavingDate", [Leaving date],
                    "@@Div", [Div], "@BU", [BU], "@QuittingReason", [Quitting reason], "@QuittingType", [Quitting type],
                    "@WorkingHours", [Work hours], "@FTE", [FTE], "@Location", [Location], "@position", [Position]
                ),
                ALLEXCEPT ( 'Employee Data', 'Employee Data'[Name] )
            )
        )
    )
RETURN
    IF ( DistinctRows = 2, "Yes", "" )

Not sure what exactly you're looking for but following is one way of doing that.

Differences? = 
VAR DistinctRows =
    COUNTROWS (
        DISTINCT (
            FILTER (
                ALLEXCEPT ( 'Employee Data', 'Employee Data'[DataSource] ),
                'Employee Data'[ID] = SELECTEDVALUE ( 'Employee Data'[ID] )
            )
        )
    )
RETURN
    IF ( DistinctRows = 2, "Yes", "" )

    I get the following error trying your solution: 

    A circular dependency was detected: Employee_Data[Differences?].

    The output should be a new column in the data source table as you did it. 

    It would be useful to have an additional column, which is empty by default, but in case of difference it would show the name of the column that differs.
