Request that the message is discarded if it cannot be delivered to its intended destination.
Set the property to MQRO_DISCARD_MSG to request that the message is discarded if it cannot be delivered to its intended destination. If you require the message to be put on a dead letter queue instead, or sent to an exception destination, do not set the property. By default, the property is not set.
The value MQRO_DISCARD_MSG corresponds to a report option that can be specified in the Report field of a message descriptor. For more information about this option, see the WebSphere MQ Application Programming Reference.
