When integrating with GXS OpenText, I recently encountered an issue with an AS2 setup.
- You receive an inbound message over AS2.
- The AS2 client is setup to receive an asynchronous MDN regardless of the use of a encryption/signing or compression.
- You’ve setup a two-way send port to send out the asynchronous MDN.
- The two-way send port uses AS2Send and AS2Receive pipelines.
With this setup, we encountered the following AS2 error:
An output message of the component “Microsoft.BizTalk.EdiInt.PipelineComponents” in receive pipeline “Microsoft.BizTalk.EdiInt.DefaultPipelines.AS2Receive, Microsoft.BizTalk.Edi.EdiIntPipelines, Version=22.214.171.124, Culture=neutral, PublicKeyToken=31bf3856ad364e35” is suspended due to the following error:
An AS2 message was received that did not contain the AS2-From header..
The sequence number of the suspended message is 2.
