Hello,
so far, e.g. before SP12 I used the field "conversionid" in my ccBPM to connect two messages together. My scenario is that I receive data for an IDOC from a web service which I send via the IDOC adapter to R/3 and then I send an ALEAUD back to my ccBPM which answers the SOAP call. I use the S/A Bridge for that. ws -> xi -> idoc -> r/3 -> idoc -> xi -> ws.
I used the conversionid which was the same on the sending the idoc and the receiving of the ALEAUD. Now after SP12 it is empty.
What have other people used to correlate two message other then payload information as the ALEAUD does not have a great payload.
I sure could extend the ALEAUD to send the right fields back but I like that the ccBPM has its own connection fields you could use (At least you can select them in the correlation editor).
Thanks
Stefan
