I have a simple flow as below

MQInput -> Compute -> MQOutput

This flow separates a fixed legth message as separate messages considering ORDER as delimiter.

Input message : ORDERlksldfjORDERlsdfjsdORDERlhflksdf

Ouput shoudl be 3 messages

ORDERlksldfj
ORDERlsdfjsd
ORDERlhflksdf

My esql in compute node looks like this :

Quote:

For iRef InputRoot.MRM.ORDER[] Do
PROPAGATE DELETE NONE;
END FOR;

I expected every order to come out from output terminal as separate message but this is not happening.
But I get the input message thrice in the output queue instead of it getting separated as 3 different messages. I am able to see the message getting parsed properly as expected in the compute node in the visual debug mode. All 3 messages get separated but once propagated the whole messge get out thrice.

Do I need to create a messge set for ouput and map in the compute node and then propagate or is there any other way in the ESQL to handle it.

Please help. Thanks

Check out your propagate statement. Could the delete none be at fault?

The PROPAGATE statement just propagates what is in the Output* trees at the time it is called. If you want to change the contents of the OutputRoot message before it is propagated, you need to assign the contents of your iRef to the OutputRoot tree before you call propagate...

I used Set OuputRoot.BLOB.BLOB = InputRoot.MRM.Order[Count]

It's workign fine now.

Thanks everybody !!!
