How to do i work with outbound messages like DESADV and VDA4913

Hi Everyone,

Well i tried the method RMG told to view the document type but had no success. I am working on WM 4.6.
Is there any other way i can see the content of the file being sent out?
Actually what i am trying to do is, I need to send the document to GXS server to be able to send out the EDI(DESADV) message.
For the time being i am using my own profile as the sender as well as the receiver.
I am using wm.tn.receive to send the the DESADV message from developer to the TN.
I have installed the DESADV96A document type in the TN. Made a processing rule which delivers the document into a public queue.
This public queue is using VANFTP as the delivery service.

Can you tell me how to make sure that correct data is being sent out and see the content of the file being sent out?
Would GXS be able to identify the receiver?
How to make sure that document is reaching GXS server?

I will be obliged if someone would help me out.

Thanks,
Parul.
