Can I get the Atom Q generated message ID inside the process?
No, its not possible to get message ID in the process.
Please have a look: Can the unique Message ID from the Atom Queue be retrieved in a Boomi process?
May i know the use case that you wanted to retrieve message ID?
Basically, I am planning to push the failed message to a backout Q to be reprocessed later on. So If I have already successfully processed an recent version of the message from the source, I don't want to reprocesses the older version of the message from the backout Q. If I can compare the Message ID along with the account ID from the message payload, I will know if I am dealing with a recent version or an older version of the message/account ID combo.
Interesting use case. You can check if there's already an idea for this or otherwise log a new idea. Ideas for Boomi
