SYMPTOMS

Consider the following scenario:

You use Microsoft BizTalk Server 2006 R2 to receive AS2 messages from a trading partner and to then send Message Disposition Notification (MDN) messages back to the trading partner.
You click to select the Activate AS2 Reporting check box on the general AS2 properties page for the trading partner.
You receive an AS2 message from the trading partner. The message contains a Carriage Return Line Feed (CRLF) in the AS2 Content-Type field of the HTTP header. For example, you receive an AS2 Content-Type field that resembles the following:

Content-Type: application/edi-x12;
name=from_XYZ_to_ABC
BizTalk Server sends an MDN message back to the trading partner successfully.

In this scenario, you cannot find the message from the AS2 Message and Correlated MDN Status Report in BizTalk Server Administration. Additionally, you receive the following error message in the Application log:

Event ID 4112 :

System.FormatException: The specified content type is invalid.
at System.Net.Mime.ContentType.ParseValue()
at System.Net.Mime.ContentType..ctor(String contentType)
at Microsoft.BizTalk.EdiInt.Reporting.AS2MessageActivity.ValidateParameters()
at Microsoft.BizTalk.EdiInt.Reporting.AS2MessageActivity.Create()

Event ID 8132 :

An error was encountered when attempting to generate an AS2 status report. Error: The specified content type is invalid.

Notes

This issue occurs even if you enable the Unfold HTTP headers AS2 property for the trading partner. The Unfold HTTP headers AS2 property enables BizTalk Server to unfold HTTP content-type headers into a single line.
The issue typically occurs when the trading partner uses a third-party AS2 application that wraps the HTTP header of the AS2 messages when the header exceeds a specified length.
