Not able to see Incoterms in Complex Purchase order

Summary:

In the standard Document Style, fields like shipping method, freight terms, and Incoterms (e.g., FOB) are visible. However, when selecting the Document Style as Complex Work Purchase Order for a lump-sum line item, these Incoterm fields do not appear. Why is there a difference in visibility between the two document styles?

Is there any setup which can default these terms in Complex PO?
