Hello Everyone,
I am new to WMB (9.0) and having an issue with message mapping the thing is that I want to copy InputLocalEnvironment to OutputLocalEnvironment using message map and override one field OutputLocalEnvironment/Destination/MQ/DestinationData[1]/newCorrelId but I am not getting data in the next node. I have also check user trace in debug mode but unable to understand it. I also tried using MQMD/CorrelId but the same issue except MQMD header is initialized in message map since no copying and i get the default values in next nodes.
Only if I initialized OutputLocalEnvironment (not copy with input) and only move some field into OutputLocalEnvironment/Destination/MQ/DestinationData[1]/newCorrelId only then I am getting that field data in next node. Any suggestions will be appreciated.[/url] |

Hi
Can you be a bit more specific, what data is not getting into the Mapping node output?, the existing input content of LocalEnvironment or the Overriden newCorrelId?
If the later, where is the value coming from?
How exactly are you copying the existing content of LocalEnvironment? is your Move with Overrides at the root of LocalEnvironment?
Which v9 fixpack level are you using? |

Well I am copying existing LocalEnvironment into OutputLocalEnvironment and changing the value of
OutputLocalEnvironment/Destination/MQ/DestinationData[1]/newCorrelId
with a String field in my input message using Move with override operation and i am not getting value of newCorrelId in output of mapping node.
I also tried initializing a new MQMD header and setting the value in MQMD/CorrelId using the mapping node but the same thing not getting the newly set value in output node.
Only if a initialized a new OutputLocalEnvironment then move a string field in input message to OutputLocalEnvironment/Destination/MQ/DestinationData[1]/newCorrelId
only then i am getting newly set data in the output node.
I haven't updated fixpacks, current IIB version is 9.0.0.1.
I hope this clariefies everything.
I could have attached a screenshot or included user trace log in debug mode but it seems like attachments are disable in this forum. |

I was able to recreate this kind of issue if the input side folder in which you need to Move / Assign data into with a Move with Override transform does not exist.
So for your case I would expect that on the input to the mapping node
| Code: |
| LocalEnvironment/Destination/MQ/DestinationData |
does not exist in the tree.
In this case the Map is not correctly creating that folder and adding your new child element when you use Move with Overrides.
The same is seen in 9.0.0.2.
So yes, need to use your workaround of initializing the required additional folder in output and moving in value and copying over existing data, rather than simply using an Override until this is fixed.
Good to get this reported to IBM support via a PMR. |

| Yes that's the case, my input side values does not exists. Thanks for confirming that. |
