How can I retrive the first sender?

Question

Hi Guru.
So this is my scenario:
JDBC_System, here starts the process, "sends" some data to a BPM.
The BPM call a custom RFC in the R3_System.
When the R3_System sends the response, I lost the "original sender" (in this case JDBC_System) because the sender is R3_system and receiver is the BPM.
So, I need the "original sender" (JDBC_System) because I need to send an alert to some people.
I cannot modify the RFC in SAP System.
In the future I can have more JDBC_system and for each JDBC_System and I need to send an email to several users.
How can i do this?
Thanks thanks guru.
Bye

What do you mean with <UniqueID> is the message ID of the first step (JDBC to BPM) or is a "cross id" for all the step in the flow?
