    See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test (later on when you use the query on your dataset, you will have to change the source appropriately. If you have columns other than these, then delete Changed type step and do a Changed type for complete table from UI again)

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCgwMNDRS0lEyNDIGkhEREUqxOghRE5Cgi4sLWBBIuwaBBIxMTIGko6MjmrCxCZAMD0cVNQaZExSkFBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [CODE = _t, VALOR = _t, PRODUCT = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"CODE", type text}, {"VALOR", Int64.Type}, {"PRODUCT", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"CODE"}, {{"VALOR", each List.Max([VALOR]), type nullable number}}),
    #"Merged Queries" = Table.NestedJoin(#"Grouped Rows", {"CODE", "VALOR"}, #"Changed Type", {"CODE", "VALOR"}, "Grouped Rows", JoinKind.LeftOuter),
    #"Expanded Grouped Rows" = Table.ExpandTableColumn(#"Merged Queries", "Grouped Rows", {"PRODUCT"}, {"PRODUCT"})
in
    #"Expanded Grouped Rows"

    your help worked thank you very much. 🙂

    your help worked thank you very much.
    I tried to do it again step by step but I couldn't understand how you did to merge the table, could you please explain to me?

    To merge I don't need another table?

      First you self merge (i.e. same step to step), then you go to the merge statement and change the step name to another step name.
