calculated column

Hi dianate12 

You can do this in Power Query or DAX.

Power Query:

Add a new column with the following code:

Table.SelectRows( Table.Group(#"Changed Type", {"Parts"}, {{"MinCode", each List.Min([code]), type nullable number}}) , (x) => x[Parts] = [Parts] )

Expand the column and do a replace values with the following expression:

= Table.ReplaceValue(#"Changed Type1",each  [#"Yes/No"], each if [#"Yes/No"] = "0" then "Yes" else "No",Replacer.ReplaceText,{"Yes/No"})

Result below:

Full code:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSlTSUTJQitWBsIzgLGMwKwkvKxmuAxsrBW5yCooYUG8sAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Parts = _t, code = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Parts", type text}, {"code", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "MinCode", each Table.SelectRows( Table.Group(#"Changed Type", {"Parts"}, {{"MinCode", each List.Min([code]), type nullable number}}) , (x) => x[Parts] = [Parts] )),
    #"Expanded Custom1" = Table.ExpandTableColumn(#"Added Custom", "MinCode", {"MinCode"}, {"Yes/No"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Expanded Custom1",{{"Yes/No", type text}}),
    #"Replaced Value" = Table.ReplaceValue(#"Changed Type1",each  [#"Yes/No"], each if [#"Yes/No"] = "0" then "Yes" else "No",Replacer.ReplaceText,{"Yes/No"})
in
    #"Replaced Value"

DAX:

Yes / No DAX =
VAR tt = 'Table'[Parts]
RETURN
    IF (
        MINX (
            FILTER ( ALL ( 'Table'[Parts], 'Table'[code] ), 'Table'[Parts] = tt ),
            'Table'[code]
        ) = 0,
        "Yes",
        "No"
    )
