How can an XML error be corrected without compromising the accounting record?

⚠ Machine-translated answer, not yet manually reviewed. For the exact wording, see the Slovak original.

Short answer

First distinguish a technical export or mapping error from a change to the accounting content. Correct technical mapping in the ERP or transformation layer. Correct a commercial or accounting fact only through the approved accounting and tax procedure appropriate to that change.

Technique

Mapping and format

For example, an empty element, bad code number or wrong order can be a technical export error.

Content

Suma is not cosmetics

If you change the price, VAT, customer or delivery date, it's not just an XML fix.

Audit trail

Keep track

Save the original file, the validation report, the change made and the person who approved the correction.

Process

Please correct at the source

The best correction is in the ERP data or the exporter, so that the error is not repeated with the next invoice.

Conclusion: Do not edit the XML file as if it were an ordinary text file without a record. Secure editing means distinguishing between technical and accounting aspects whilst maintaining the audit trail.
