Transmission of messages
Article 58
1. All transmissions shall be fully automated and immediate, using the transportation layer. 2. Before transmitting a message, the sender shall perform an automatic check to verify that the message is correct according to the minimum set of validation rules as described in the relevant implementation documents. 3. The receiver shall inform the sender of the reception of the message by transmitting a response message based on UN/FLUX P1000-1: General Principles. The response message shall be in line with the specifications described in the relevant implementation documents and shall at least indicate if the message has been accepted or rejected. Where the receiver rejects a message, the sender shall investigate the reasons for the rejection and, where necessary, correct the data as needed without delay. The sender shall then send a new message with the corrected data, in line with the procedures described in the implementation documents. Response messages shall not be subject to further response. 4. When a technical failure occurs on the sender’s side and the sender can no longer exchange messages, the sender shall notify all receivers of the problem and immediately take appropriate actions to correct the issue. All messages that need to be delivered to a receiver shall be stored until the problem is resolved. After the repair of such a technical failure, the sender shall transmit unsent messages as soon as possible. 5. When a technical failure occurs on the receiver side and the receiver can no longer receive messages, the receiver shall notify all parties connected to the transportation layer of the problem and immediately take appropriate actions to correct the issue. After the repair of such a technical failure, the sender shall make all missing messages available upon request. 6. In the event of a transportation layer’s failure preventing data exchanges, the Commission shall notify all affected parties. Senders shall store all undelivered messages until the issue is resolved. Once the failure is repaired, the Commission shall inform all connected parties, and senders shall transmit any pending messages as soon as possible. 7. Member States and the Commission shall establish failover procedures for business continuity.
