M language Maximum Value

[newgirl]

Hi!

I have a "Text after delimeter" column that shows 3 values - 20, 21, and B. I want to add another column in the Query Editor that if the value is B, it should instead show whatever is the maximum value from the "Text after delimeter" column.

Would appreciate the help!

Hi @newgirl ,

you can do it like this:

// Table
let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjJQitUBUoZgygnCQWIbWirFxgIA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Text After Delimiter" = _t]),
    #"Added Custom" = Table.AddColumn(Source, "Only numbers", each try Number.From([Text After Delimiter]) otherwise null),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Insert Max", each if [Only numbers] <> null then [Only numbers] else List.Max(#"Added Custom"[Only numbers])),
    #"Changed Type" = Table.TransformColumnTypes(#"Added Custom1",{{"Only numbers", type number}, {"Insert Max", type number}})
in
    #"Changed Type"
