Need to update RFH2 header in receiver JMS channel

Hello All,

I had implemented the updating of RFH2 header details by creating a dynamic udf and then making the changes in JMS receiver channel by selecting the option "Use Adapter Sepecific Message Attributes" as shown below in the screenshot.

But now the clients want some more details to be inputted into the RFH2 header. They want all of the details mentioned above to be inputted into a XML tag called TietoRouter in RFH2 part and also create another tag called "CustomNew" to input the user details.

Please help me with this.

Thanks,

Ajeya G V
