91.2. Why Am I Getting a "Duplicate External Reference ID" Error on my Report?
If you are amending a report and are getting the "Duplicate External Reference ID" in the OK Guardian system, that is because those transactions are already in the system and do not need to be added again. When Amending a report, you would only need to import new transactions that are being added and did not exist on the original filed report.
If you need to edit or delete a transaction that was on the original report, that can be done in the Guardian system. All you would need to do is hover your cursor over "Financial" and choose which type of transaction needs to be edited. You will then be brought to a screen where you can edit, delete, or refund transactions.
