Hi Ian,
Regarding your queries:
1) You need to register OTM's WSDL with the external partner system (Let's say BPEL or WebM). This WSDL can be generated from OTM from: BPA>>Integration>>Integration Manager>>Retrieve WSDLs>>IntXMLService. Click on the WSDL URL and it will load the WSDL which can be registered on the partner link.
2)You can record the OTM Transmission Manager No. into that XML. For this you need to set the AckSpec segment in your GlogXML as follows:
a. Mention the ComMethodGid.Gid.Xid (Eg. SERVICE)
b. ServletURL: External System's end-point URL
Eg:
http://206.245.44.101:8897/orabpel/d...ERVPROV204/1.0
c. AckOption: YES
I haven't tried responses other than the one mentioned above, so would not be able to comment on that as of now.
Let me know your outcome.
Regards,
Naveen Gupta
