FIX: MDNs are not sent to the sending party in BizTalk Server 2006 R2

This article has been archived. It is offered "as is" and will no longer be updated.
Consider the following scenario:
  • On a computer that has Microsoft BizTalk 2006 R2 installed, you use the AS2EDIReceive pipeline to receive and process Applicability Statement 2 (AS2) messages from your trading partners.
  • You configure the receive port to receive the AS2 messages, and synchronously send a Message Disposition Notification (MDN) to the sending party.
  • You receive an incoming AS2 message that is not parsed correctly by the EDI pipeline components.
In this scenario, the AS2 message will be suspended, and the MDN is not sent to the sending party as expected.

For example, in BizTalk Server you receive an AS2 message whose field delimiter/separator and segment delimiter/separator are the same. In this situation, the AS2 message will be suspended because of a parsing error. Additionally, you will receive an application event log that resembles the following:

Event Type: Error
Event Source: BizTalk Server 2006
Event ID: 5719
There was a failure executing the receive pipeline: "Microsoft.BizTalk.EdiInt.DefaultPipelines.AS2EdiReceive, Microsoft.BizTalk.Edi.EdiIntPipelines, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "EDI disassembler" Receive Port: "<Receive Port>" URI: "<URI>" Reason: Delimiters are not unique, field and segment seperator are the same

When this problem occurs, the MDN is not sent to the sending party as expected.
