When a Scheduled Item encounters an error, it will not be scheduled again because it is likely in a state where it cannot run (ex: Shortage of disk space, missing Report, etc.). You can view errors of a Scheduled Item to investigate the cause of the error.
To view the errors of a Scheduled Item:
The Scheduler window opens.
The Scheduled Item Error window opens to provide details on the error(s) that occurred when the Scheduler attempted to run the Scheduled Item.
Note: If a Scheduled Item has an error, it will not be scheduled to run again. Select the Reset to pending status so item will be scheduled again check box to ensure that the Scheduled Item will run after any errors have been resolved.
