Acknowledgment Processing

• Adapter Generates HL7 Acknowledgment

  In this scenario, the Adapter generates an HL7 ACK after receiving and successfully storing the message in a queue; otherwise, it generates an HL7 NAK. The HL7 ACK or NAK is placed in the proper envelope and sent to the external system.

• ESB Sends HL7 Acknowledgement

  In this scenario, the Adapter acts as a sender in a Delayed ACK scenario, as described in Delayed ACK Mode.

• Canned HL7 NAK

  A Canned HL7 NAK is created when a read error occurs, or when an message cannot be identified as an HL7 message. The initial test ensures that the message conforms to the lower-layer protocol. The Resource Adapter uses the MSH section parameters to create an appropriate NAK.
