Rejected: duplicate submission
LHDN refuses a document that matches one it already received. This usually means your first submission went through, and the second attempt was the extra one.
What you see
In the Rejection reason box: "This document was already submitted to MyInvois, so it was not sent again." LHDN's code is DV302.
How LHDN decides it is a duplicate
LHDN flags a document as a duplicate only when all of these match another document it processed within 2 hours:
- e-Invoice type and version
- Issue date and time
- Internal ID or invoice number
- Supplier TIN (for normal e-invoices), or buyer TIN (for self-billed e-invoices)
What to do
Usually nothing. The earlier submission stands.
- Open Documents and search for the invoice number.
- Find the earlier copy. If it is Validated, you are done.
- If you cannot find a validated copy, open the duplicate and click Send to support.
Do not create the same sale again with a new number to get around this. That would file the sale twice at LHDN.
Why it can happen
- The same sale was submitted twice in quick succession, for example a double click, or a sale sent both from a connected store and by hand.
- A connected system retried a sale that had already been filed.
When envoice sees that a resubmitted document was already filed, it skips the repeat, and the document's Audit trail shows "Resubmit skipped (already filed)".
