I have a requirement...Let say there are two flows each consisting of MQInput--->Compute--->MQOutput, output of first flow act as a input of another flow. We are transforming the input message in first flow. Now requiremnt is, we need the transformed and original message both at a part of transaction in second flow. How can we achieve this??

Do you mean that you want the original message rolled back onto the original input queue in the event of a failure?

Rewrite this as a single flow.

If, however, you mean that you need both the original message and the resulting transformed message both available to the second flow then you simply have the first flow produce a copy of the original message and the transformed message as output (consider a FlowOrder node). You then correlate both messages in the second flow using a Collector node and presto! The contents of both messages are in the same message tree in the second flow.

Sorted.

By transforming the message to contain the data you need in the second flow.
