Power query to find the duplicate entry with specific condition

Hello vjnvinod 

 

use Table.Group and then add a new column, where you check a) if it has more then 1 row and if the hours-column has all the same absolute number. in this case 3 row of hours with values - 5, 5, -5 would result in no

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXIEYgNDPSAyMgAydU2VYnWwykAkjIAsJ5CEKVzCBCxhDGQ5o0oYgyVMgCwXVAkjXEYZKsXGAgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Employee GUI" = _t, #"Engagemend ID" = _t, #"Transaction Date" = _t, Hours = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Employee GUI", Int64.Type}, {"Engagemend ID", type text}, {"Transaction Date", type date}, {"Hours", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Employee GUI", "Engagemend ID", "Transaction Date"}, {{"AllRows", each _, type table [Employee GUI=number, Engagemend ID=text, Transaction Date=date, Hours=number]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Custom", each if Table.RowCount([AllRows])>1 and List.Accumulate([AllRows][Hours], [AllRows][Hours]{0}, (o,n)=> if Number.Abs(o)=Number.Abs(n) then Number.Abs(n) else 0)=Number.Abs([AllRows][Hours]{0}) then "no" else "yes"),
    #"Expanded AllRows" = Table.ExpandTableColumn(#"Added Custom", "AllRows", {"Hours"}, {"Hours"})
in
    #"Expanded AllRows"

 another approach would be to sum the hours and if the result is 0 write no. Here an example

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXIEYgNDPSAyMgAydU2VYnWwykAkjIAsJ5CEKVzCBCxhDGQ5o0oYgyVMgCwXVAkjXEYZKsXGAgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Employee GUI" = _t, #"Engagemend ID" = _t, #"Transaction Date" = _t, Hours = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Employee GUI", Int64.Type}, {"Engagemend ID", type text}, {"Transaction Date", type date}, {"Hours", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Employee GUI", "Engagemend ID", "Transaction Date"}, {{"AllRows", each _, type table [Employee GUI=number, Engagemend ID=text, Transaction Date=date, Hours=number]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Custom", each if Table.RowCount([AllRows])>1 and List.Sum([AllRows][Hours])=0 then "no" else "yes"),
    #"Expanded AllRows" = Table.ExpandTableColumn(#"Added Custom", "AllRows", {"Hours"}, {"Hours"})
in
    #"Expanded AllRows"
