What application are you using?
What processing are you doing?
What do your error logs tell you about why the backout is happening?
If no errors, are you sure you don't have your backout queue and output queue definitions muddled in some config? |

| websphere process server and websphere MQ, we are not able to see any exceptions in SysOut and SysErr logs of process server, we don't have any control on MQ part, only some successful messages are going to Backout queue, is there any way we can check through websphere process server admin console , why messages are going to backout queue ? |

Hi prithvik,
MQ will only backout a message to the backout queue if the transaction containing the mq get is rolled back by WPS/WAS.
WPS will rollback back that transaction when some error occurs that prevents that transaction being completed.
Exactly what else that transaction contains in WPS depends on your application configuration. You've not told us much about the application so it's hard to speculate. More information about what is in the application would help.
When you say that this is a "successful message" can you please elaborate why you think that. Clearly there was an error that caused the message to be backed out. What indicates that the message was successful ? |

| thanks wooda for the reply. By proper exception handling ... this issue seems to resolved as this is not occured in recent times. Successful message mean , it saved to DB. as you said , if it saves to one table of DB , we assume it is success , but , it failed for other tables , it went to back out queue is assumption. Any way thanks for the reply. |
