We are using BizTalk 2010.

We send one AS2 package to our TP and our TP send us back 4 Acknowledgement files.

Most of the acknowledgement files that we receive from the TP contains the ReceivedFileName property which contains the file name, except for the 1st acknowledgement or the MDN, which doesnt contain the file name.

Our TP has informed us that they do send us the MDN with a file name.

In our BizTalk 2010 system :

- We have a One-way receive port, which monitors all the content received from TP.

- We have defined a CustomPipeline for all inbound AS2 packages (AS2Receive pipeline). In this custom pipeline, in the Execute method, I had looked at all the properties from the base message context. I was not able to find ReceivedFileName, PreservedFileName, AS2PayloadContentType properties. I also looked at the InBoundHttpHeaders and couldnt find the file name in there. 

I heard that BizTalk 2010 has fixed this issue. Where can I find what was fixed? I had looked at the following links, but it didnt help:

Is there any other place, I could look for the file name?
And what could be reason that, the system is able to retain the file name for all the other acknowledgement, but for Ack1/MDN?
Or is there a way to look at the raw content with the header send by my TP? (tried using Fiddler / Wireshark)
Or is there a way to prove, that I indeed not receive any file name?

Thanks for your

Hi VNSuvarna,

You can also use Fiddler, it captures HTTP(S) traffic and logs it for the user to review.
