What do I do if I get the message: "A Pre-production record already exists for Monitor-Date-Time"?

The following process needs to be run:

  1. Understand: The error is caused by pre-production raw data that has not been posted.
  2. Review the load report and note the monitor id(s) (state-county-site-parameter-poc) of the raw data with this error.
  3. To delete this data, run the Maintain -> Sample Values -> Delete Preproduction data form.
  4. On that form, query the monitor id(s) with the error (state-county-site-parameter-poc)
  5. Once the data has been retrieved and visible on the form, click the "Delete All Selected" button.
  6. Repeat the above for all monitors with the error.
  7. Click on the Batch menu pick.
  8. On the Batch form, click on either the "Load File" or "Post File" button to resubmit.
  9. When the job completes, look at the counts and reports to see if there are other errors.
