After you generate output, you can validate your output using ePublisher reports. ePublisher reports contain information about how ePublisher processed items in your source documents when ePublisher generated output. Reports also allow you to identify any problems that occurred when ePublisher generated output. If reports display notifications, such as messages, warnings, or errors, you can correct the items in your source documents that caused the error. You can then generate output again and then review the reports again to verify that any issues have been addressed as needed.
