A compromise approach is for the requestor to keep a map of request IDs and business object IDs. This is especially useful when the requestor wants to keep the object IDs private or when the requestor has no control over the replier’s implementation and can only depend on the replier copying the request’s message ID into the reply’s correlation ID. In this case, when the requestor gets the reply, it looks up the correlation ID in the map to get the business object ID and then uses that to resume performing the business task using the reply data.
