Min/MAX column with numeric maximum value

[Binara]

Hello all,

I am trying to add a cusom column to calculate the Max and Min for 3 columns(More in the future). Issue is that the data is alphanumeric for Cancelled values. So when I try it, I get the maximum value in letters. Is there anyway to get the highest numeric value as the Max, in this situation. Here is the sample table I am trying to work on. 

As you can see, I get the MAX as "Cancelled", but I am trying to get "23" as the result.

I am using this basic DAX -  

List.Max ({[D1],[D2],[D3]})

I am rather new to this, so I might be asking something very simple. Any assistance is much appreciated. Thank you,

Binara

Hi @Binara ,

Try copying this query in your advanced editor:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjRX0lHKK83JgVGxOtFKRsZAnnNiXnJqTk5qCpBtaKkUGwsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [D1 = _t, D2 = _t, D3 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"D1", type text}, {"D2", type text}, {"D3", type text}}),
    Custom1 = Table.AddColumn(#"Changed Type", "Lists", each Text.Split(Text.Combine({[D1],[D2],[D3]},"|"),"|")),
    Custom2 = Table.AddColumn(#"Custom1", "MaxVal", each List.Max(List.Transform([Lists], each try Number.FromText(_) otherwise null))),
    Custom3 = Table.AddColumn(#"Custom2", "MinVal", each List.Min(List.Transform([Lists], each try Number.FromText(_) otherwise null))),
    #"Removed Columns" = Table.RemoveColumns(Custom3,{"Lists"})
in
    #"Removed Columns"
