CDS 10001 – Mandatory Data Element has not been provided

System: CDS

Error Code: CDS 10001 (CDS-10001)

Explanation

Obligation error: Mandatory Data Element has not been provided

When it happens (Reason)

This error occurs when the declaration does not include all mandatory data elements. The system checks each required DE, and if any part is missing or incomplete, the declaration is rejected. For example, when declaring a party name and address, all parts such as name, street and number, country, and postcode must be fully completed.

Quick Fix

Check the declaration to confirm all mandatory data elements are completed in full.

Step-by-step resolution

1. Check the declaration to confirm all mandatory data elements are completed in full.

2. Review each field where required information is expected.

3. Ensure no mandatory fields are left blank or partially filled.

4. If declaring a party name and address, make sure all components — name, street and number, country, and postcode — are provided.

5. Submit the declaration again after all required details are entered correctly.
