Based on Bryan Cheong’s original video. Reviewed 28 September 2026.
A validated e-Invoice cannot be corrected simply by changing the invoice on your computer. Some internal SQL Accounting fields may remain editable because they were not sent to LHDN. The first question is therefore which field you need to change.
In this video, Bryan Cheong explains the distinction between the information in the validated submission and the additional details used to organise an accounting record.
Which information should you treat as validated data?
Bryan gives examples such as the buyer’s company name and address, item description, amount and unit of measurement. If a submitted value is wrong, editing a local record does not amend the document already validated by MyInvois.
Check the actual submitted data, rather than assuming that every field named “Description” behaves the same way. An item description in the submission and an internal document heading can serve different purposes.
Which internal fields may still be editable?
The video identifies account code, location, additional descriptions, Remark 2 and the document header description as examples of information that may be maintained within SQL Accounting without having been submitted to LHDN. Availability depends on the software version, configuration and user permissions.
This is a distinction between submitted information and internal information. “Optional” alone is not a safe test: an optional field that was included in the submitted document is still part of that submission.
A practical check before changing anything
- Identify the document, its validation status and the exact field involved.
- Compare that field with the validated e-Invoice details.
- If it is an internal field only, confirm that your system permits the change and retain a record of the reason.
- If the submitted information is wrong, use the applicable MyInvois correction process rather than relying on a local edit.
- Check the final customer-facing document and your internal records for consistency.
What if the information sent to LHDN is wrong?
MyInvois documentation permits cancellation within 72 hours of validation, subject to the document’s status and applicable conditions. After that period, corrections may require a credit note, debit note or refund note, as appropriate. The correct document depends on the error; do not assume a credit note is suitable for every case.
Frequently asked questions
Can I change Remark 2?
It is one of the internal-field examples in the video. Confirm that it was not included in your submission and that your SQL version allows the edit.
Does the Edit button mean I can amend the validated amount?
No. An editable accounting screen does not itself change the validated MyInvois document.
