How do I correct an error after a transaction is committed?

If a mistake is identified after a transaction has been digitally committed (for example, incorrect items declared or typing errors in Customs remarks), the transaction must be cancelled in the system to allow for a correction.

The Cancellation Procedure

1. Mutual Consent: A cancellation can only be performed with the mutual agreement of both the Customs officer and the carnet holder or representative.
2. Holder Provides Code: The holder or representative must locate the unique cancellation code within their ATA Carnet App or Desktop application. This code is found directly underneath the specific transaction QR code that was just processed.
3. Customs Entry: The Customs officer must manually input this code into the ATA Carnet Customs (ACC) portal to initiate the cancellation.
4. Recording the Reason: The officer must enter a free-text reason for the cancellation. This reason is stored in the ATA Carnet Core and is visible to all other Customs officers within the same country for audit and transparency.
5. Discarding the Record: Once the cancellation is submitted, the committed record is discarded, effectively "rolling back" the transaction in the system.

Next Steps for Correction

• Amending the Declaration: After the officer confirms the cancellation, the holder must go to the Travels tab in their application, click Edit on the prepared travel, correct the data (e.g., updating the list of goods), and Save the updated travel.
• Reprocessing: The application will generate a new transaction QR code based on the amended data. The holder then presents this new QR code to the Customs officer to re-process the transaction correctly from the beginning.

Important Operational Rules

• Time Sensitivity: While the system allows for cancellation, it is strongly recommended that this be done while the holder is still at the Customs office so the officer who committed the original transaction can immediately rectify it.
• EU Two-Step Export: In the European Union, an "Export without exit" step (pre-exportation) cannot be cancelled. This specific rule aligns with traditional paper carnet logic to avoid the generation of duplicate export receipts.
