AS2 Solution Architecture
AS2 processing is performed separately from EDI processing. AS2 messages are received, processed, and an acknowledgment sent apart from the processing of the EDI payload. As a result, AS2 processing is designed and configured apart from EDI processing. In addition, you can use AS2 to transport either EDI messages or non-EDI messages.
This section describes the architecture of AS2 solutions on BizTalk Server, including end-to-end, receive-side, and send-side processing.
