I have an old message flow which produce a big simple XML message as follow:
Flow_1:
MQINPUT-->MQSI_NODES_1-->MQOUTPUT
The message in the Output queue is like: <message>big.......message</message>.

The current application MQGET the message, simply strip off the XML tag and process the content (big....message).

Now customer wants to use MQSI to process the big...message instead. A MRM definition was prepared for "big...message".

A separate flow was developed as follow:
Flow_2
MQINPUT(MRM)-->MQSI_nodes_2-->MQOUTPUT
The message pick up by the MQINPUT node is just the "big...message" without the XML tag
(<message> & </message>). This flow was tested OK by itself and produced the desired output in the Output queue.

They thought they can combine the two flows by making Flow_2 a sub-flow.
The replace the MQINPUT and MQOUTPUT of Flow_2 by InputTerminal and OutputTerminal and call it Sub_flow_2.

They then insert sub_flow_2 into Flow_1 :
MQINPUT-->MQSI_NODES_2-->Sub_flow_2-->MQOUTPUT
and think that the new flow will produce the same output as Flow_2

From the surface, this seems logical.But the new flow fails.
I think one reason for the failure is they miss the fact that the message tree just before MQOUTPUT of Flow_1 is built by the XML parser (with a single element, big...message) where as the Flow_2 is working with the tree built by MRM parser with many fields elements. Please correct me if I am wrong.

Can some one help us on how to get this to work ?

I figure out how to get it to work. We have to use the resetcontentdescriptor node to reparse the message into MRM format.
