When generating and submitting e-invoices in the UAE PINT format, businesses may encounter various XML-related errors. These errors typically occur due to formatting issues, missing mandatory fields, or invalid values. Below is a list of common issues and how Taxilla helps prevent or resolve them.
| Error Code | Error Message | Root Cause | Resolution |
|---|---|---|---|
| 1001 | Missing mandatory field: Invoice Issue Date | Invoice Date field is empty or not mapped | Ensure the invoice issue date is present and follows the YYYY-MM-DD format. Taxilla flags this automatically. |
| 1002 | Invalid currency code | Currency code not compliant with ISO 4217 | Use correct 3-letter currency code (e.g., AED). Taxilla enforces ISO format validation. |
| 1003 | Tax amount mismatch | Line item tax total doesn’t match header total | Check line-level tax calculations. Taxilla runs cross-field validation. |
| 1004 | Buyer TRN invalid or missing | TRN field missing for VAT-registered customer | Ensure TRN is provided and valid. Taxilla marks TRN as conditional based on registration status. |
| 1005 | Incorrect date format | Non-ISO date format (e.g., DD/MM/YYYY) used | Use ISO 8601 format (YYYY-MM-DD). Taxilla auto-converts valid date entries. |
Taxilla includes a real-time validation engine that highlights these and other issues before the invoice is submitted, helping businesses stay compliant and avoid rejections.
Not all submission errors are caused by the invoice structure. Some issues occur during the transmission process or in the response from the Peppol or FTA endpoints. Here's how to troubleshoot:
Check Submission Logs: Access Taxilla's dashboard to review XML validation reports and transformation logs.
Review Field Mappings: Confirm whether ERP data is correctly mapped to the PINT schema.
Validate Digital Signature: Ensure the signing certificate is active and properly embedded.
Check Network & Delivery Status:
Was the document successfully transmitted to the Peppol Access Point?
Was it acknowledged by the buyer's Access Point?
FTA Data Reporting:
Was the data accepted by the FTA?
Look for status codes or rejection messages returned from the FTA endpoint.
Submission accepted by Peppol but rejected by FTA: Review the content for PINT-specific rules not enforced at the Peppol level.
Invoice stuck in 'Pending' state: Check internet connectivity and retry via Taxilla interface.
Digital signature invalid: Re-issue the certificate and re-sign the XML.
Taxilla provides an integrated monitoring panel to view status at each stage of the invoice lifecycle.
