Remove all rows with same value in collumn

Hi!

 

How I can remove all rows with same value in collumn.

 

Remove 2 rows column Chave 3007291109 for example.

 

When using Remove Duplicates it does not answer me. I need both to be excluded.

Take a look at what this code is doing. Paste it in a blank query. It removes all non-unique records.

 

1) In Power Query, select New Source, then Blank Query
2) On the Home ribbon, select "Advanced Editor" button
3) Remove everything you see, then paste the M code I've given you in that box.
4) Press Done

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSlSK1YlWSgKTyWAyBUymgsk0MJkOJhORyCQklUAyFgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Column1"}, {{"Count", each Table.RowCount(_), type number}, {"All Rows", each _, type table [Column1=text]}}),
    #"Filtered Rows" = Table.SelectRows(#"Grouped Rows", each ([Count] = 1)),
    #"Expanded All Rows" = Table.ExpandTableColumn(#"Filtered Rows", "All Rows", {"Column1"}, {"Column1.1"})
in
    #"Expanded All Rows"

I assume you are trying to do this in Power Query? If so, @ImkeF and @edhans

In DAX you would create a column like:
Column = COUNTROWS(FILTER('Table',[Chave] = EARLIER([Chave]))

Then a table like:
Table = FILTER('Table',[Column] < 2)
