This means any failure in the message processing will be returned as an HTTP error to the caller in the case of EAI bridges, and the message will be pushed to the suspend endpoint in the case of B2B bridges. The suspend endpoint is important in the case of B2B as the error in configuration or message structure cannot be sent back to the business partner, but is meant for consumption by the IT operator. This means in both EAI and B2B scenarios, all retries and resubmissions of messages post failures have to be done outside the bridge.
