Hi
I am facing a problem . I am using Propagate funcion to generate the two messages different in one field with each other in output from single input message .
The two messages generated has same messageIds which is creating problem in other system . They are only able to pick one message of same ID. I need to change the MessageId so that the broker generate the different Ids for two messages after propagation.
I searched on IBM catalogue and not able to find out this.
How can I achieve this?
Please guide .
Thanks |

Thanks all.
I explored and found that we can reset the messageId like below
I have done 'MQMI_NONE' as below and it worked 
| Code: |
SET OutputRoot.MQMD = InputRoot.MQMD;
SET OutputRoot.MQMD.MsgId= MQMI_NONE; |
Anyone has to comment on this ? |

| you can also use MQHeader node to do this. |

But i suspec that we cant use it when the message being generated using PROPOGATE function. The Header node can work for the single input and output message I guess.
Correct me if I am wrong.  |

there is no limitation like "we cant use it when the message being generated using PROPOGATE function". Its all about how you code your flow

yes. if you propagate multiple messages to OutQ through MQHeader Node which has MQMD.MsgId= MQMI_NONE then you can achieve the same. |

Why suspect or guess? A few minutes of experimentation will tell you one way or the other.

Think about what the MQHeader node is doing. Then explain to me how what it does will differ if the message tree arriving at its In terminal is doing so because of a RETURN TRUE in an ESQL Compute node, a PROPAGATE in an ESQL Compute node or because it's being sent from any of the other nodes in the Toolkit.
Or what led you to "guess" or "suspect" it made a difference.
