convert null numbers for duplicate lines

[JoaoFidalgo94]

Hi everyone!

Could you please help me with this issue?

For example this table:

Ref.	Qtd. OK	Qtd. NOK	Cod. OP	Id.1
1533	2	7	A	123456
1533	2	48	B	123456
1533	4	10	C	987654

Now, my problem is I want to keep the lines but i dont want to duplicate the values on "Qtd. OK" column, is there any way of null the duplicate value on "Qtd. OK" if lines of "Id.1" are the same? Or create a new column like "Ajust Qtd.Ok"? Like this:

Ref.	Qtd. OK	Qtd. NOK	Cod. OP	Id.1
1533	2	7	A	123456
1533	null	48	B	123456
1533	4	10	C	987654

Grouping by Id.1 with no aggregation then filling down the Qtd. OK column might work for you.

You can select column "Qtd. OK" and from the transform tab pick Fill Down if all the first ref value does not include null, else make group by first, then use fill down

Hi,

Thanks for the solution Omid_Motamedise  and jgeddes  offered, and i want to offer some more information for user to refer to.

hello @JoaoFidalgo94 , you can create a blank query and put the following code to advanced editor in power query.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQ1NlbSUTICYnMgdgRiQyNjE1MzpVgdFFkTCyDhhFXaBCRqACScgdjSwtzM1EQpNhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Ref." = _t, #"Qtd. OK" = _t, #"Qtd. NOK" = _t, #"Cod. OP" = _t, Id.1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Ref.", Int64.Type}, {"Qtd. OK", Int64.Type}, {"Qtd. NOK", Int64.Type}, {"Cod. OP", type text}, {"Id.1", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Ref.", "Qtd. OK"}, {{"Count", each Table.AddIndexColumn(_,"Index",1,1),type table}}),
    #"Expanded Count" = Table.ExpandTableColumn(#"Grouped Rows", "Count", {"Qtd. NOK", "Cod. OP", "Id.1", "Index"}, {"Qtd. NOK", "Cod. OP", "Id.1", "Index"}),
    #"Replaced Value" = Table.ReplaceValue(#"Expanded Count",each [Qtd. OK],each if [Index]=1 then [Qtd. OK] else null,Replacer.ReplaceValue,{"Qtd. OK"}),
    #"Removed Columns" = Table.RemoveColumns(#"Replaced Value",{"Index"})
in
    #"Removed Columns"

Output

Best Regards!
