I want to link EDI documents in TN using the conversation ID. My problem is that TN is creating new conversation IDs for each transaction-level document, even when the instance IDs are the same. For example, an inbound 850 is received and gets a conversation ID of senderID-receiverID-instanceID. An outbound 870 with the same instanceID (PO number) is later received and gets a new conversation ID, even though the docs say that for the second document it should try to use an existing ID by flipping the sender and receiver to search for it.
Where is TN looking for the existing ID – documents or process models? I have not created a business process in Modeler for this, and would prefer not to if possible. Thanks,
