Biztalk AS2 MDN AS2EdiReceive "No Disassemble stage components can recognize the data"

Question

Okay, I've looked through all the walkthroughs on the MSDN.. and I don't know what's happening. I've got an asynchronous MDN that's being received by my One-Way port which has the pipeline as "AS2EdiReceive".

All EDI files come in fine. It's the MDN files that generate the "No Disassemble stage components can recognize the data". Here's the exact error:

There was a failure executing the receive pipeline: "Microsoft.BizTalk.EdiInt.DefaultPipelines.AS2EdiReceive, Microsoft.BizTalk.Edi.EdiIntPipelines, Version=3.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "EDI disassembler" Receive Port: "prtMicroEDIRCV" URI: "/sorocmicrous/BTSHTTPReceive.dll" Reason: No Disassemble stage components can recognize the data.

If I check the message context, the IsAS2MdnResponseMessage = True. So It obviously knows it's an MDN. I can't figure out how to get this MDN past this.

Answer 1

I'm pretty sure I found the answer. and it was on this web page:

http://msdn.microsoft.com/en-us/library/bb728190(v=BTS.20).aspx

And in the second paragraph it says:

However, if you use AS2EdiReceive, you cannot route the MDN into the MessageBox by setting the "Process inbound MDN into MessageBox for routing/delivery options" property (for the party as AS2 message receiver). Trying to do so will result in an EDI error because the MSN will be passed to the EDI Decoder, which cannot process an MDN. If the MDN is not sent to the MessageBox, the AS2Decoder will consume the MDN, so it will not be passed to the EDI Decoder.

I'm monitoring it now, but it seems to have done the job.
