attachments over AS2 RRS feed

  • Question

  • I want to send and receive attachments along with the AS2 payload. Has any one did similar thing? It was mentioned in documetation that BizTalk supports this capability, but there is no help on how we can acjieve that. Am I missing any documentation regarding this?

  • This is mentioned as one of the characteristics of the BizTalk AS2 Drummond certification. So probably what it means on a technical level is that the payload on an AS2 message can be multiple separated files. This may be simply a batch of EDI messages. I think if you needed to send multiple messages that were not EDI you would need to use some custom technique - maybe a custom pipeline component or custom adapter.

    I could not find any examples of how to do this out of the box either. It seems like there would be a property on the ports like if you always wanted to add a file, but I could not find one. I will email someone at Microsoft about this to follow up.

    Thanks,

  • Hi Yallamanda,
    For using Multiple Attachments in As2.

    A Few things need to be done for sending a Multiple Attachment As2 Message.
    1. Creating a Custom pipeline component first which can add Parts to your BizTalk message from files or a database.
    2. You have to add your attachments as Parts in the pipeline component and then pass it through As2 Send Encoder to get a Multiple Attachment Message.
    [Your pipeline should contain the Custom Component to add the Parts to the BizTalk Message and then the AS2 Encoder]

    To Receive a Multiple Attachment message,
    As2 Receive pipeline will automatically split the received AS2 Message into body and Parts (Attachments). Further processing can be done on the Parts via custom pipeline component or an orchestration.

    For Creating the Custom Pipeline Component please look up:
    http://blogs.msdn.com/brajens/archive/2007/01/28/how-to-develop-biztalk-custom-pipeline-components-part3.aspx

    Will look into missing documentation issue for this feature and get back to you on this thread.

  • I think this is basically handled as different parts of the overall steam as MIME parts. This blog post explains some of these details: Basically it is handled through MIME headers: http://blogs.msdn.com/biztalkb2b/archive/2009/08/05/as2-filename-preservation.aspx.

  • Hi,

    I am trying to understand the business scenario where you need to use the multiple attachment feature. Is it for attachments with HIPAA documents or for some other domain?

    Thanks!

  • AS2 does not support attachments 

    Documentation

  • An 8 year old thread? Please

    EDIT: Referenced article (Attachments for AS2 messages are not supported in send or receive) is related to Azure BizTalk Services (MABS) which is deprecated

    BizTalk:

    AS2 supports MIME and MIME supports multiple attachments

    The basic structure of an AS2 message consists of MIME format inside an HTTP message with additional AS2-specific headers. The nature of the message beneath the HTTP, AS2, and MIME headers depends upon the type of message
