Hi, Anonymous ;

You could add conditional column as follow:

Then add another conditional column.

The final show:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlbSUfJNzYspNTAwMi9G5cTqRCuZAoXC83ORVaBwQWrMgILemSkIFUgckLwRuh1uibmZOZVgORMEF8NuQ0J2xwIA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Hours = _t, #"Project Catagory" = _t, #"Production Catagory" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Hours", Int64.Type}, {"Project Catagory", type text}, {"Production Catagory", type text}}),
    #"Added Conditional Column" = Table.AddColumn(#"Changed Type", "Internal", each if [Project Catagory] = [Production Catagory] then [Hours] else null),
    #"Added Conditional Column1" = Table.AddColumn(#"Added Conditional Column", "External", each if [Project Catagory] <> [Production Catagory] then [Hours] else null)
in
    #"Added Conditional Column1"
