How do I correct EMCS transactions?

According to the German EMCS procedural guidelines, the following applies to an e-AD: 
Neither the draft e-AD nor the e-AD transmitted to the consignor may be corrected by the user or the consignor. If a draft e-AD is rejected for technical or substantive reasons, the consignor must submit a new draft. It is not possible to correct the transmitted data.

Therefore, check whether you can cancel the movement or change the destination. If necessary, consult with your main customs office. For more information, see the following articles:

• Cancellation: When can an EMCS submission be cancelled?
• Change of destination: When and for whom may the destination be changed for an EMCS submission?

Have you received an EMCS completion notification, but the data does not match the shipment? Then you have the option to send an alert regarding the shipment to the sender, or to reject the delivery entirely. Alternatively you can report discrepancies and excess quantities for individual items back to the sender.

Feedback on the shipment

For alerts or rejections that apply to the entire EMCS discharge, use the Send alert/rejection hyperlink in the Assistant column.

You can select from the following reasons in the window displayed.

3 - The quantity does not match the order
