@mqjeff and @rekarm01 - Thank you for the response. I agree that using ESQL with compute nodes is a better way of achieving this. But my constraint is that, I will not have access to modifying the flo ...

Are you sure your User Exit isn't rewriting the value when the MQInput node reads from Q3?

That is, overwriting the value.

Yes, I am not doing any processing on input callback. So the "tra ...

Thank you for your responses, everyone. Really appreciate it.

As suggested by @mqjeff, I am now modifying the MQRFH2/usr in MQOutput node. As a first step, I am trying to make sure that I am able t ...

Thank you @rekarm01

Looking at the rest of the JMSTransport header, the problem could be that "testKey" is an Attribute, when it probably should be an Element:

@mqjeff, thank you for the suggestion.
