Hello @Anonymous 

check out this approach. Uses Table.TransformRows to make duplicates of your rows, and apply then needed changes. Afterwards the data is transformed back from a list of records to a table.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTIy0DMw1DMyADKNgUxTCNPQAAiAdE5+cYlSrE60khOQY2CpZ2AEk9cDIoguU4jS/ILUPKXYWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Customer = _t, #"Start Date" = _t, #"Close date" = _t, Amount = _t, Status = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Customer", type text}, {"Start Date", type date}, {"Close date", type date}, {"Amount", Int64.Type}, {"Status", type text}}, "de-DE"), 
    TransformRows= Table.TransformRows
    (
        #"Changed Type",
        (row)=> 
        let 
            HoOftenDuplicate =  Number.RoundDown(Duration.TotalDays(row[Close date]- row[Start Date])/30, 0),
            Duplicate = List.Transform(List.Numbers(0, HoOftenDuplicate), (translist)=> Record.TransformFields(row, {{"Start Date", each Date.AddMonths(_, translist)}}))
        in 
            Duplicate
    ),
    CreateFinalTable = Table.FromRecords(List.Combine(TransformRows))
in
    CreateFinalTable

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
