Remote Delta Links
With the content usage mode Remote Delta Links you can reuse different kinds of pcd objects like iViews, pages, worksets, and roles in your consumer portal from a remote location. Some content is maintained on a producer (like iViews and pages). On the consumer portal you can create delta-links to this remote content and adjust properties according to your needs. The runtime execution of the content still remains on its origin - the producer portal. More information is available on the links below.
