Hello.. 

I have a table such as below. I want to subtract the failed call from the total call and put the result in a new row (success_call).

Can anyone who has information about this subject help me?

Call Type	Count
total_call	10000
Failed_call	100
Success_Call	9900	new rows

Hi @u4us1923, you can do this easily in Excel but here you go:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WKskvScyJT07MyVHSUTI0AAKlWJ1oJbfEzJzUFCRxpdhYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Call Type" = _t, Count = _t]),
    ChangedType = Table.TransformColumnTypes(Source,{{"Count", type number}}),
    Ad_SuccessCall_Row = Table.InsertRows(ChangedType, 2, {
        [ Call Type = "Success_Call", 
          Count = [ t = Table.SelectRows(ChangedType, (x)=> Text.Contains(x[Call Type], "total", Comparer.OrdinalIgnoreCase))[Count]{0}?,
                    f = Table.SelectRows(ChangedType, (x)=> Text.Contains(x[Call Type], "failed", Comparer.OrdinalIgnoreCase))[Count]{0}?,
                    result = t-f
                  ][result]
        ] } )
in
    Ad_SuccessCall_Row
