About Load reports
When you load data from DataHub, the system generates reports that log the upload progress, and reports that show any issues encountered, such as a validation report if validation fails.
These reports are saved to the same DataHub folder you selected your DAT, LST, or OPT file. To review a job's reports, navigate to that folder in DataHub.
If the job fails for one or more documents, the system also generates a retry DAT file in that folder. Use this file to correct the errors and retry the load, you can retry the same job multiple times until it completes successfully. For the full procedure, refer to the Load a production from DataHub topic.
