If you attempt to upload a file but your file is not accepted by e-GGRT, it is generally because your files has a fatal flaw or is missing essential data. The reason why the file was not acceptable is displayed as a screen error on the upload page. For an example of a screen error message, see below.

During the upload, e-GGRT will generate a validation report which will list potential deficiencies or issues with your reporting form.  Click on the "Subpart SS: View Validation" link to review your validation report. An explanation of the validation report and the process for correcting validation issues prior to submission is presented in Reporting Form Validation

Once you have addressed the validation issues to the extent you believe necessary, and once you have completed any other applicable subparts, you must generate, review, certify, and submit your annual report as described in How to Submit an Annual Report
