As suggested in the Admin Reference Manual, you might want to make sure
the optionstring and objectstring of the schedule is correctly specified.
Here is an excerpt from the Admin Reference Manual.

   Result
       Specifies the return code from the client that identifies
       whether the schedule has executed successfully. If the
       return code is something other than a zero, examine the
       option string you specified using the OPTIONS parameter
       or the object string you specified using the OBJECTS
       parameter in the DEFINE SCHEDULE command.

Hope this helps,
