ORA-55511: Flashback Transaction experienced error in executing undo SQL

What triggered the Error:

There was a constraint violation exception when executing in NOCASCADE_FORCE mode. Users could also get this error if appropriate supplemental logging is not enabled causing constraint dependencies to go unnoticed.

What should we do to fix it:

Either use CASCADE or NONCONFLICT_ONLY options or add appropriate level for supplemental logging.
