Remove rows based on error code

let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content], 
    result = Table.RemoveMatchingRows(
        Source, 
        Table.ToRecords(
            Table.SelectRows(Source, (x) => x[Error Code] = 1)[[Data], [Company]]
        ),
        {"Data", "Company"}
    )
in
    result

Hi gianchan ,
You can try this

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("dY5LCsAgDETvkrVgTGs/y2puId7/GjUgVOq4GAJ5TPJKocA+eGHZydHTcrUwVTcTm2EiqeWAHSMRkrz8Y+SGf9S2DEv6Pyej9rkkEZLUFTCRUU5GbYYdIxvsaL82d/QzqC8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Company = _t, Total = _t, #"Error Code" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Company", type text}, {"Total", Int64.Type}, {"Error Code", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Date", "Company"}, {{"GroupedData", each _, type table [Date=nullable date, Company=nullable text, Total=nullable number, Error Code=nullable number]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "HasErrorCode1", each if List.Contains([GroupedData][Error Code], 1) then 1 else 0),
    #"Expanded GroupedData" = Table.ExpandTableColumn(#"Added Custom", "GroupedData", {"Total", "Error Code"}, {"Total", "Error Code"}),
    #"Filtered Rows" = Table.SelectRows(#"Expanded GroupedData", each ([HasErrorCode1] = 0)),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"HasErrorCode1"})
in
    #"Removed Columns"

Final output
