My MQInput Node parses the incoming message into an MRM.

If my Mapping Node fails for some reason, I want to catch the error, then create a new message for a REJECT Queue, which includes both the Exception List AND the original message data.

Is there any way to access an unparsed version of the original MQ message once the flow has been started and the MQInput node has parsed it into a known MessageFormat?

Yes - set your REJECT queue as the backout queue on the input queue. Broker will automatically put the message there if the flow fails. If you want to process the rejected message, wire up the Failure terminal on the MQInput node.

Yes.

Don't do the parsing in the MQInput Node
Set the MQINPUT Node to use BLOB Format
Place a Compute Node right after the MQInput Node

set Environment.Message.Save = InputRoot.BLOB.BLOB;

The place a RCD node after the compute node with the message parsing setup just like you have in the MQInput Node.

Obviously, this is just the barebones. I'd also add a Try-Catch Node into the equation and then down the Catch Path assemble the data you need to put on the Error Queue.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.
