Hola @JorgePereira ,

Pruebe este mcode:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCsnPTSzJV9JRMjQAEo5KsTrRSs6JRUX5JUCuKVzIPy8zPw/Is0AoKk0uzU1KLQJpNYKLwo0DKXRCNc0IU8gQZIMzig2GxhChWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Product = _t, Amount = _t, Store = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Product", type text}, {"Amount", Int64.Type}, {"Store", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Product"}, {
                                {"Amount", each List.Sum([Amount]), type nullable number},
                                {"Store", each Text.Combine([Store], "-"), type text}
                            }
                            
                            )
in
    #"Grouped Rows"
