    Hi Drors

     

    Try this solution

     

    Go to Modelling Tab>>> New Table

     

    New Table =
GENERATE (
    TableName,
    VAR mymonth = MONTH ( TableName[Date] ) RETURN GENERATESERIES ( 0, 11, 1 )
)

    Now Add this CALCULATED COLUMN to your NEW TABLE

     

    New date =
DATE ( YEAR ( 'New Table'[Date] ), MONTH ( 'New Table'[Date] ) + 'New Table'[Value], DAY ( 'New Table'[Date] ) )

This would be my Power Query solution:

 

let
    Source = TableName,
    DateList = Table.TransformColumns(Source,{{"Date", (startdate) => List.Transform({0..11}, each Date.AddMonths(startdate,_)), type {date}}}),
    #"Expanded Date" = Table.ExpandListColumn(DateList, "Date")
in
    #"Expanded Date"
