Use the MQRR structure
These structures are destination specific; each Response Record contains a CompCode and Reason field for each queue of a distribution list. You must use this structure to enable you to distinguish where any problems lie.
For example, if you receive a reason code of MQRC_MULTIPLE_REASONS and your distribution list contains five destination queues, you will not know which queues the problems apply to if you do not use this structure. However, if you have a completion code and reason code for each destination, we can locate the errors more easily.
See the Application Programming Reference for further information about the MQRR structure.
