Access Message ID in BPM.
I have a requirement of accessing the message ID in BPM.
In few blogs it is mentioned that the header parameters are not available for mappings used inside the BPM.
When I tried BPM with only one message as input, I was able to get the message ID in the transformation step. The same doesn't work when my BPM accepts more than one message as input. Below is the BPM design.
This is a simple collect payload BPM I tried. I am grouping 3 messages and then sending to transformation step. But the message ID field is not getting generated.
Please provide any pointers. Thanks.
