BPEL-B2B integration using default AQ

Question

I'm trying to invoke a partnerlink that will call Integration B2B to send an EDI 850. I followed the instruction in BPEL_B2B.zip that came with Integration B2B. I was able to setup the partnerlink and used WSIF to select the appropriate 850 document. My question is: where in the PartnerLink or Invoke function can I assign the IP_MESSAGE_TYPE with appropriate from/to id information before the document goes to B2B. Do I need to define this IP_MESSAGE_TYPE? I have been trying to find documentation that describes how to do this in BPEL and I haven't been able to. Your help is greatly appreciate.

Answer 1

This information goes in the AQ header. To create the AQ header variable, go to the invoke activity that connects to your AQ partnerlink. Open up the properties for the invoke and go to the "Adapters" tab. You'll see a field for the input header variable. To create this, click on the flashlight and use the variable chooser to create a new variable called "b2bHeader" or something like that. This variable will be a message of type Header_msg which you'll find in the WSDL for your AQ partnerlink. Once you've created the variable, you can assign the message type, etc. as needed.
There may be another (simpler) way to do this, but this seems to work fine for me.
