Windchill business objects that are both Releasable and Promotable (such as parts, documents, process plans and resources) may be added to a promotion request and promoted to a target lifecycle state (such as RELEASED), thereby triggering their publication. While this was possible even in a previous release of ESI, it would often result in multiple Release To Manufacturing (RTM) workflows, with each promotable in the promotion request spawning a separate workflow, thereby leading to performance issues. At 10.1, by setting a certain Windchill ESI preference, all the objects in a promotion request may be published in one go, via a single RTM workflow.

Windchill ESI services process a promotion request and its promotable using the APIs of class ESIPromotionRequestRenderer. See the Promotion Request Classes section for more information.
