    Hola @toum ,

    ¿Qué te parece esto?

    Aquí el código que puedes pegar en el editor avanzado. Siéntase libre de consultar los pasos en el lado derecho también 🙂

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUQKhWJ1oJScgwxGMQTxnIMsJJuWCzHFDUecBZLnBpIKBjCAwBvG8gaxgsFQsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t, Home = _t, Destination = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Name", type text}, {"Home", type text}, {"Destination", type text}}),
    #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"Home"}, #"Changed Type", {"Name"}, "Added Custom", JoinKind.LeftOuter),
    #"Expanded Added Custom2" = Table.ExpandTableColumn(#"Merged Queries", "Added Custom", {"Destination"}, {"Added Custom.Destination"}),
    #"Added Custom" = Table.AddColumn(#"Expanded Added Custom2", "NewColumn", each if [Destination] = "" then [Added Custom.Destination] else [Destination]),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Added Custom.Destination"}),
    #"Sorted Rows" = Table.Sort(#"Removed Columns",{{"Name", Order.Ascending}})
in
    #"Sorted Rows"

    Espero que esto ayude 🙂

      Muchas gracias por su ayuda, eso es lo que necesitaba, pero por favor, otra cosa para la fila1 la NewColumn debe ser A. (si el destino está vacío y Name=Home o Home está vacío, la newColumn debe = Name).
