Document to Document Relationships (Projects and Programs)
There are multiple types of document to document relationships in Windchill ProjectLink:
A document can reference another document from the Related Objects tab on the document information page. This relationship creates a link of type WTDocumentDependencyLink.
A document can serve as the parent to a second child document from the Structure tab on the document information page. This relationship creates a link of type Document Usage link (WTDocumentUsageLink).
There are no configuration options available for document to document relationships.
