Build a repeatable process for preserving evidence, decoding rules, correcting data and safely resubmitting.

What it means

A useful rejection record includes the authority code, rule ID, severity, document path, message, original request and correlation identifier.

Human-friendly explanations should never replace the raw machine response.

Implementation method

  1. 1
    Persist the rejected source and response before retrying.
  2. 2
    Normalize common states while retaining provider-specific detail.
  3. 3
    Link rule codes to source-system fields and owners.
  4. 4
    Fix the upstream mapping, rerun validation and submit idempotently.

Questions and answers

Should every warning block submission?

Follow the active profile and provider severity. Some warnings are informational locally but rejected by a network implementation.

How should support teams reproduce an error?

Use the preserved source hash, payload, environment, schema versions, request ID and raw response.

Can EInvoiceLab officially certify invoice rejection handling?

No. EInvoiceLab can inspect, prepare and explain technical data, but official conformance, delivery or acceptance depends on the active authority, network, accredited provider and validation artefacts.

Should I keep the original structured file?

Yes. Preserve the original XML or JSON, its hash, every validation report and the final authority or network response. A readable PDF should not replace the source document.
