FIX: A Request Response Receive Location that uses an MLLP adapter does not work correctly if you configure the per-instance pipeline properties for the custom send pipeline when you use Microsoft BizTalk 2009 Accelerator for HL7


View products that this article applies to.

Symptoms

Consider the following scenario,
  • On a computer that is running Microsoft BizTalk Server 2009, you have installed Microsoft BizTalk 2009 Accelerator for HL7(BTAHL7).
  • In BTAHL7 Configuration Explorer, you enable the option "Route ACK to send pipeline on request-response receive port", and you set Acknowledgement type to "OriginalMode" for an HL7 trading party.
  • You create a Request Response Receive Location that uses a Minimal Lower Layer Protocol (MLLP) adapter to receive HL7 messages.
  • You use a custom pipeline as a send pipeline for the Request Response Receive Location, and you configure the per-instance pipeline properties for the custom pipeline.
In this scenario, the per-instance pipeline properties do not take effect during message processing. Therefore, BTAHL7 does not promote the necessary properties to process the Acknowledgements (ACK). When this occurs, the Request Response Receive Location does not work as expected.

Cause

This problem occurs because of an error in Microsoft BizTalk 2009 Accelerator for HL7. Because of this error, ACKs are not processed correctly.

When the MLLP receive adapter operates in two-way mode, the adapter will not receive a new message from the connection until the pipeline has generated the acknowledgement (ACK) for the previous message. Therefore, the Request Response Receive Location described in the "Symptoms" section does not work as expected.

Workaround

To work around this problem, set the Acknowledgement type to "None" in BTAHL7 Configuration Explorer for the HL7 trading party. In this manner, the ACKs will be processed correctly with the Configuration of the Per-instance Pipeline Properties. Therefore, the Request Response Receive Location works as expected.
