Symptoms

Consider the following scenario:

  • You install Microsoft BizTalk 2009 Accelerator for HL7 (BTAHL7) on a computer that is running Microsoft BizTalk Server 2009.

  • You create a receive location. You configure it to use the MLLP adapter.

  • The receive location has a custom pipeline component. You configure it to promote some context properties.

  • You do not deploy the property schema that defines the promoted properties.

  • A message arrives at the receive location.

In this scenario, the MLLP adapter does not log any exception, the message is not suspended, and you are not notified of any error.

Cause

This issue occurs because of the design of the MLLP adapter. 

When the pipeline component that uses the MLLP adapter calls the Promote method, the messaging engine does not find a property schema. However, the message engine does not explicitly generate an exception. Therefore, the message is not published later in the process.

Resolution

Note To resolve this issue, apply the following hotfix. After you apply the hotfix, BizTalk Server uses HL7 Logging Service to log that the message engine did not find a property schema. Therefore, you must run the HL7 Logging Service if you want BizTalk Server to log an entry when a property schema is not found.
