SYMPTOMS

Considering the following scenario:
  • You use the Microsoft BizTalk Accelerator for HL7 2.0 or Microsoft BizTalk Accelerator for HL7 1.3 to create an MLLP send port to receive acknowledgements (ACK).
  • In the Transport Advanced Options settings for this port, you enable the "Ordered delivery" option and the "Stop sending subsequent messages on current message failure" option.
  • The MSA1 field of the acknowledgement contains a value other than AA or CA.
In this scenario, messages start to queue up, and an event message that resembles the following message is logged in the Application log:

Event Type: Error
Event Source: BizTalk Server 2006
Event Category: BizTalk Server 2006
Event ID: 5812
Description:
The ordered delivery send port: "<Send Port Name>" has stopped processing messages. To rectify the issue please use Biztalk Management Console to find the failed message corresponding to the Send Port Instance ID:"{GUID}" to further diagnose the issue. After fixing the error, please resume the send port instance.

Notes
  • You can enable an MLLP static one-way port to receive acknowledgements by specifying the "Solicit Response Enabled" option as Yes, and by specifying an Acknowledgement type in the BizTalk Accelerator for HL7 Configuration Explorer. See the "More Information" section in this article for a link to detailed instructions. The functionality that is documented in this hotfix is available only when you use a static one-way port for which the "Solicit-Response enabled" option is specified as True.
  • Depending on your settings in the Acceptable ACK Codes property of the MLLP Send Port Configuration dialog box, you may see the following warning logged in the Application log:

    Event Type: Warning
    Event Source: BizTalk Server 2006
    Event Category: BizTalk Server 2006
    Event ID: 5743
    Description:
    The adapter failed to transmit message going to send port "<Send Port Name>" with URL "<URL>". It will be retransmitted after the retry interval specified for this Send Port. Details:"Acknowledgement type Error was received".

  • If this retry attempt fails, and if the acknowledgement that is returned contains an invalid MSA1 field, you receive an error message in Application log that resembles the following message:

    Event Type: Error
    Event Source: BizTalk Server 2006
    Event Category: BizTalk Server 2006
    Event ID: 5754
    Description:
    A message sent to adapter "MLLP" on send port "<Send Port Name>" with URI "<URI>" is suspended. Error details: Acknowledgement type Reject was received MessageId: <GUID> InstanceID: <GUID>

  • If the downstream system does not send an acknowledgement message, another attempt is made to resend the message according to the Transport property options (retry count and retry interval) that are specified in the send port. You receive entries in the Application log that resemble the following entry:

    Event Type: Error
    Event Source: BizTalk Accelerator for HL7
    Event Category: None
    Event ID: 8451
    Description:
    Unable to receive ACK from network due to error "MLLP Send adapter timed out while receiving the ACK.".

    Event Type: Warning
    Event Source: BizTalk Server 2006
    Event Category: BizTalk Server 2006
    Event ID: 5743
    Description:
    The adapter failed to transmit message going to send port <send port name> with URL "localhost:18000". It will be retransmitted after the retry interval specified for this Send Port. Details:"MLLP Send adapter timed out while receiving the ACK."

  • If no acknowledgement is received after the message attempt is made, the message becomes suspended in the Group Hub of the Microsoft BizTalk Server Administration console. You receive entries in the Application log that identify the port name and the suspended message (event ID 5812 and 5754).

CAUSE

This problem occurs because the BizTalk Accelerator for HL7 treats only the AA and CA codes for MSA1 as valid. Any other MSA1 code is rejected.

Note Because of file dependencies, the most recent hotfix that contains these files may also contain additional files.After you apply this hotfix, we provide support for additional ACK codes in addition to AA and CA. These codes are AE, AR, CR, and CE. After you apply this hotfix, these additional MSA1 codes are accepted as valid, and no additional processing is provided to handle these codes.

WORKAROUND

To work around this problem, you can disable the "Ordered delivery" option and the “Stop sending subsequent messages on current message failure" option on the send port if these options are not required to maintain order.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

After you apply this hotfiix, a new "Acceptable ACK Codes" setting becomes available in the Transport properties of the MLLP Send Port Configuration dialog box. For compatibility, the default setting is AA and CA. The following code setting options are available for the properties:
  • AA and CA
  • AA, CA, AE, and CE
  • AA, CA, AR, and CR
  • All ACK codes
This setting controls the message processing when the following settings are specified:
  • Solicit - Response Enabled: Yes
  • Ordered delivery: Enabled
  • Stop sending subsequent messages on current message failure: Enabled
