I don't quite understand your post - could you please explain how your modify stage uses "pdct_num"?

I'm not sure if you could add a new column and assign a default value in modify stage. It expects s mapping from input columns for any new output column. One can add a new column with a default value through a Column Generator stage (or) a Transformer stage.

You cannot create a new column and assign a default value in a modify stage, such columns need a value derived from some existing column(s). Is this what the OP meant in the original question?
