This error indicates that your account is configured to use your own custom Direct Debit references for new customers, rather than the system-generated ones. However, none have been provided in the spreadsheet.
You’ll need to enter the required Direct Debit references in column AH under the heading Contract.CustomDirectDebitRef.
📌Note: If you previously used Rapidata, you may know this field as the URN.
If you believe this setting has been applied by mistake and you shouldn’t need to provide your own Direct Debit references, please contact us through the Access Digital Assistant and reference the title of this article.
