This functionality controls the copying forward of Representations to new iterations of Representables (for example, Windchill Parts, Documents, Dynamic Documents, and Windchill Document objects). The fundamental principle is that Copy Forward applies only to out-of-the-box, non-derived Representations. However, in the case of a Copy or Revise of a Representable, all Representations (derived and non-derived) are copied forward out-of-the-box. This behavior also applies to Representables being checked out to a new context. (You can adjust this out-of-the-box behavior using the Copy Forward properties described later in this section.)

For example, where a Representation has been created from pre-converted viewables on the local file system and associated to a Windchill Part that has no describing Document, when that Windchill Part iterates, all of the Representations copy across to the new iteration, as they cannot be derived from anything.

For a Representation that is associated directly to a Document (because it has no described Windchill Part) or to a Windchill Part with an active link to a describing Document, where the Representation was derived from the Document content: for the Representation to be copied forward when the part iterates independently of the owner associated EPMDocument, but when the EPMDocument iterates, the representation forward is not copied forward. This behavior is referred to as "Restricted Mode" Copy Forward, and is enforced at the current releases, out-of-the-box.
