[ffeebr]

I have the following table

Number Area  Infotipo Tp.info Amount          Firt               Last
100035  AB     40              1      1.000.000,00   04/05/2021
100035  AB     40              1      500.000,00      23/04/2021 03/05/2021
100035  AB     40               1     400.000,00      23/04/2020 22/04/2021

Follow my excel

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("fc7NCcAgDAbQXTwL+TOtPbZriPuv0SRSD6VVMHyEPJLWEiGiaMrpvKwUtEL+MZ4lhQKM7M3U8y/QZ96mxcGwMuwCli9omV9yW9xYwaYpgsAazTsPNxxBPEyz/xsFGnsUauzpNw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Number = _t, Area = _t, Infotipo = _t, Tp.info = _t, Amount = _t, First = _t, Last = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Number", Int64.Type}, {"Area", type text}, {"Infotipo", Int64.Type}, {"Tp.info", Int64.Type}, {"Amount", Int64.Type}, {"First", type date}, {"Last", type date}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Number"}, {{"First Date", each List.Min([First]), type nullable date}}),
    #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"Number"}, #"Grouped Rows", {"Number"}, "Grouped Rows", JoinKind.LeftOuter),
    #"Expanded Grouped Rows" = Table.ExpandTableColumn(#"Merged Queries", "Grouped Rows", {"First Date"}, {"First Date"})
in
    #"Expanded Grouped Rows"
