    Hi Anonymous ， 

    You could try below M code to see whether it work or not.

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQwMFTSUcorzckBUoZKsTpgMSMgxwgmDhUzRqgzgomZYBEzBRuEJGAGNQxoeiwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [ID = _t, DEBIT = _t, CREDIT = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"DEBIT", Int64.Type}, {"CREDIT", Int64.Type}}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"ID"}, "Attribute", "Value"),
    #"Grouped Rows" = Table.Group(#"Unpivoted Columns", {"ID"}, {{"Count", each Table.RowCount(_), type number}, {"all", each _, type table [ID=number, Attribute=text, Value=number]}}),
    Custom1 = Table.ReplaceValue( #"Grouped Rows",each [Count], each if [Count]>1 then "True" else "False", Replacer.ReplaceValue, {"Count"}),
    #"Expanded all" = Table.ExpandTableColumn(Custom1, "all", {"Attribute", "Value"}, {"Attribute", "Value"}),
    #"Pivoted Column" = Table.Pivot(#"Expanded all", List.Distinct(#"Expanded all"[Attribute]), "Attribute", "Value", List.Sum)
in
    #"Pivoted Column"

Hi Greg! Thanks for your response.

 

But in my scenario I won't have nulls values in the same row for both columns.

 

I want to put a condition that if COLUMN A contains data and COLUMN B contains data then TRUE. Else would be false because on either columns a null value is displayed.

 

Hope that is clear! but thanks anyway 🙂
