Hi Desiree,
Have you tried with a retry option (continue from phase it stopped)
Also check the job logs in system for last job run for job "RSPTBFIL"
Which version of SUM is used ?
Have you checked this note
2253049 - SUM: DDDDLSRC02BT fail in RUN_RSPTBFIL_INISHD
Looks like SUM might have issue.
Thanks,
Anand Patel
