Best way to remove MQRFH Header (WMB)

I have tried many approaches just to achieve this. My goodness each approach is so unstable. It may work in environment A but then somehow does not work in environment B.

With the help from a more experienced colleague, the optimum solution for that seems to be:

1) Set the Message Domain as XMLNSC for MQInput Node.
2) Create a Compute Node then write your ESQL as follows:
CALL CopyEntireMessage();
SET OutputRoot.MQRFH2 = null;

Done! It's never been so easy. Fuck i wasted much time in this! Should have known this colleague long time back.
