title: BizTalk EDI - sending body of rejected transaction sets to port
body: <p>We have an upstream application that will generate at times functionally invalid transaction sets.</p>
  <p>I'm trying to push the message bodies of the failed transactions from the interchange and associated 999s to a send port or some other logging mechanism, while forwarding the valid transaction sets to downstream mapping process.</p>
  <p>Any ideas on accomplishing this would be helpful.</p>
