MDN Disposition Error

Hello all,

Any info regarding this error would be great.

When sending an (EDIINT) test document to our client I am getting the following error “MDN Disposition: automatic-action/MDN-sent-automatically; failed/Failure: message-deemed-invalid-due-to-unknown-from-and.or-to-parties”

Any ideas?


In your AS2 request sending to your TP is it has correct AS2-from and AS2-to details like url’s/destination etc?? Open the AS2 transaction that you sent and make sure this.

MDN will gets automatically acked with accept/reject AS2 transaction.


In your trading partner settings along with your enterprise profile, do you
have your AS2 Identifiers set?

Also, within your trading partner, do you have the proper http/https
URLs defined?
