Answer
This depends entirely on which report layout is actually being used: Sales-Part-level Document Text only pulls through automatically on IFS's own default report layout — if a custom layout (Crystal Report or StreamServe) is in use instead, that custom layout needs to be specifically configured/modified to actually display the document text, since it isn't automatic there. Separately, the Document Text box visible directly on the Customer Order header itself is a completely different mechanism — it only shows document text created directly on that specific order, not the part-level document text meant to auto-populate from the Sales Part.
