BizTalk AS2传入X12传出的TA1和997

Question

I've managed to follow the Microsoft BizTalk AS2 tutorial "Tutorial 3: AS2 Tutorial" ( https://msdn.microsoft.com/en-us/library/bb245935.aspx ) to receive an X12 message over AS2 and send back a MDN, and also the X12 TA1 and 997. I also managed to add a self-signed certificate to sign the outgoing MDN. My problm is that I also want to sign the outgoing X12 TA1 and 997 messages. How can that be done?

Answer 1

Just configure the Send Port for AS2 with your Trading Partner. The TA1 and 997/999 are just regular X12 messages.

Just to note, the Sender has to request a TA1, you shouldn't just send one unsolicited.

Answer 2

Problem resolved. I had missed to specify "Message should be signed" in the AS2 Agreement, under Validation in the outbound part. Now I can sign outgoing MDN, TA1 and 997.
