3 Delivery to Backend Route
                                                                    This route handles the delivery of claim acknowledgements to one of the adjudication systems: a SOA-based or local back-end system. The route selects a suitable adjudication system based on the Line of Business indicator, which is the first three characters of the Subscriber ID and a crosswalk file. The crosswalk is located at ${XESProfile}\config\configuration\Crosswalks\ and has the following structure:
