in the trace node
| Code: |
Root: ${Root}
TimeStamp: ${CURRENT_TIMESTAMP}
|
you should everything in your root and then u can modify to get whatever headers u want

I tried to find documentaiton which shows the logical structure of message trace node can access. I found one one place something like this:
| Quote: |
root
MQMD
.
.
.
.
MQRFH
.
.
XML
|
Is this what we can access in tracenode for manipulation?
thanks a lot |

Please get some training on WMB. You're trying to do things that show you are lacking a basic understanding of the product.
A Trace node is a node that does not alter the message, and so it does not use InputRoot, OutputRoot, or etc. It only uses Root, Environment, LocalEnvironment or etc.

By manipulation I mean, when we can extract a item from the root, we can write to a file file for example
