Impossible mapping

Hi , stanislav_dugas 

PowerBI doesn't support to  add additional rows by using measure.

You need to create a new calculated table as below:

Table 2 =
VAR tab =
    ADDCOLUMNS (
        FILTER (
        SUMMARIZE ( 'Table', 'Table'[ID], 'Table'[Delta To be added to Core] ),
        'Table'[Delta To be added to Core] <> 0
    ),
        "Value", "",
        "Solution Contribution %", "0",
        "Mapping", "Core",
        "Value After Appling contribution %", ""
    )
RETURN
    UNION (
        SUMMARIZE (
            'Table',
            'Table'[ID],
            'Table'[Delta To be added to Core],
            'Table'[Value],
            'Table'[Solution Contribution %],
            'Table'[Mapping],
            'Table'[Value After Applying contribution %]
        ),
        tab
    )

You can  also take a try the  function "append queries as new" in advanced editor.

Please check my sample file for more details.
