Hi,
The requirement is to request for a COA (confirmation of arrival) message when the message reached the destination queue.
There is facility in the MQ stage where you can enter the reply-to-q and reply-to-qmgr.
Where can I specify the MQMD - report field?
As Arnd notes, you can't set the Report header field in the MQPlugin, only in the version 8 MQ Connector. The older MQ Plugin had minimal support for reply messages, among others. The Connector supports a far larger variety of MQ message type and options for both reading and writing to MQ Series. In the connector, the Report option is a "pull down" menu item, where the confirmation possibilities can be selected.
