Understanding Cleaning Up Orphaned Data from Segment Batch Process Errors
PeopleTools provides the ability to delete orphaned data left behind after a failed run of a batch segment processing program.
Warning! Perform this clean up only when you are certain that data is orphaned and no segment processing application engine processes are running.
If the batch program is in the middle of processing or if the batch program has abnormally terminated but is to be restarted at a later time, the orphaned data is really not orphaned. Deleting orphaned data in these situations may cause processing problems for the batch program.
