Return Messaging to Windchill
ERP Connector sends a PostResult message for the primary business object, for every transaction in a given release. It also sends a subtransaction PostResult message for every object/action/distribution target (the objects are Parts, BOMs, Documents and their associations, option sets and their related objects and associations, CNs, manufacturing objects and resources). The Message field of the ESIPostResult schema is a string field that contains explanatory text about the publish status of the object and is populated with several pieces of information. For more information on the structure of the PostResult schema, see Implementing Windchill ESI.

What is described above is the default behavior and provides for open loop transactions. To configure for closed loop transactions, the ERP Connector preference Enable Post Result in the Transaction category should be set to “No”, so that the PostResult RPC is not invoked once the data reaches an ERP Connector distribution target. Besides this setting, some customization would be needed to actually publish the exported data to the destination ERP system and also invoke the PostResult RPC to record the publish status in Windchill.
