The HL7 v2 standard mandates the use of acknowledgments to ensure message delivery, critical in Healthcare. There are the “Original Mode” acknowledgments and “Enhanced Mode” acknowledgements. Within the enhanced mode acknowledgments there are “Accept Acknowledgements” and “Application Acknowledgements”.
This Note walks through development of two BPEL Module-based solutions that cooperate in generating and processing Enhanced Accept Acknowledgments using HL7 v2.3.1 messages. This discussion should apply to any v2.x, greater then v2.2, where the Enhanced Mode acknowledgments were introduced. In addition, the solutions are used to illustrate receiving HL7 BC ACK generation, when receiving an invalid HL7 message.
