Success or Failure scenario can be set by the user.

Configuration-->Project Setup-->Step 4-->Queue Mapping

Success or Failure scenarios can be set for configurations,where,Batch ID is selected in process level ,while configuring queues(step 2).Only for such configured queues,success or failure can be set in queue mapping.(step 4),That is, if the user wants to  stop moving a given number of URN and those that follow to the configured queue,they can choose failure. for instance,if a batch contains 1000 URNs and from 900th URN, the user wants the remaining 100 not be processed,but wants to put on hold or move them to exception queues,then,the user chooses failure.If they want all  URNs to move to the configured queue without change, then they choose the success scenario.
