| We have begun using WMB V8 and have started to refactor some of our request/reply flows to use DFDL. I have XML as the input with a DFDL xsd as the output. There is a need to override some of the MQMD and MQCIH fields as the output is going tho the mainframe. Our production flow sets, in the MQMD, the EXPIRY to 600, the CorrelId to MQCI_NEW_SESSION, and the Format to MQFMT_CICS. I have not had any luck getting the EXPIRY to be overridden in the ASSIGN to override the MQMD input. Just wondering if anyone has had any experience with this. Thanks. |

Hope it goes well. Are you doing this in order to get better throughput / lower CPU usage?

I don't even know what you mean by 'the ASSIGN'. I expect somebody else does, though. |

| Thanks. When I said ASSIGN, I meant in the Mapping Node, a value can be assigned to an output field. Values in the output fields in the Message Assembly can be overridden. Sorry. |

May be you are missing this,
| Quote: |
| When you first open or create a message map for the node, if you select This map is called from a message flow node and maps properties and message body, the headers in the input message are always copied to the output message without modification. To modify the message headers in a Mapping node, select This map is called from a message flow node and maps properties, headers, and message body. When you select this property, the map that is created allows additional elements, including WebSphere® MQ, HTTP, and JMS headers, to be mapped. |

| Thanks, kash, but I don't see that when I create a new mapping node in WMB V8. |

Do you see the other values being set correctly? Can you see the value of Expiry getting overridden in trace? |

Sorry - I was being a bit thick there. So you have an 'Assign' transform in your v8 map that assigns a constant value to the output field 'OutputRoot.MQMD.Expiry'. And you are not seeing the correct value in the MQ output message. Right?
btw, I didn't see a response to my question about the move to DFDL...nudge. |
