Configuring a Dynamic Send Port for Asynchronous MDNs over AS2
To send an asynchronous EDIINT/AS2-encoded MDN message over HTTP/HTTPS, create a dynamic HTTP send port with the following configuration:
| Location | Property | Setting |
|---|---|---|
| Send Port Properties: General | Port Type | Dynamic One-Way |
| Send Port Properties: General | Send pipeline | AS2Send |
| Send Port Properties: Filters | Property | EdiIntAS.IsAS2AsynchronousMdn |
| Send Port Properties: Filters | Operator | == |
| Send Port Properties: Filters | Value | True |
An asynchronous MDN should be sent to the address contained in the Receipt-Delivery-Option header of the received AS2 message. A dynamic send port will do so, whereas a static send port will send the message to the Destination URL in the send port definition. The exception to this is if the Use agreement settings for validation and MDN instead of message header property is set in Validation page of the one-way agreement tab of the Agreement Properties dialog box. In that case, the send port will send the MDN message to the URL entered into the Receipt-Delivery-Option agreement property. However, the send port used to do so must still be a dynamic send port, not a static send port.
You can configure this send port to return both MDNs and EDI acknowledgments. In the instance, if an EDIINT/AS2-encoded message is transported over HTTP/HTTPS successfully, but processing of the EDI-encoded payload fails, the sender of the original message would receive both an MDN indicating successful AS2 processing and an EDI acknowledgment indicating a failure in EDI processing. The EDI-encoded payload would be suspended and an error posted.
Functionality
The send port and pipeline must do the following to send an MDN:
Pick up the MDN by filtering on the
EdiIntAS.IsAS2AsynchronousMdn==Trueproperty.Build an AS2 message. For more information about this process, see Generating an Outgoing AS2 Message.
Route the MDN to the address in the Receipt-Delivery-Option line in the header of the message.
Note
If the Use agreement settings for validation and MDN instead of message header property is set in Validation page of the one-way agreement tab of the Agreement Properties dialog box, the send port will send the MDN message to the URL entered into the Receipt-Delivery-Option agreement property, not to the address mentioned in Receipt-Delivery-Option header of the received AS2 message.
