How to correct an expense classification already sent
Sent the wrong category or E3 code to myDATA? No cancellation needed: the classification is corrected by sending it again.
The rule
When you send the expense classification of an invoice again with the same identifiers, AADE accepts it, issues a new classification MARK and the new one replaces the previous one (API documentation v2.0.2, section 4.1).
What to watch for
- Send all the lines of the invoice together, not just the one that changes; otherwise AADE rejects the submission (error 304).
- Check the invoice type, category and E3 code combination before sending (errors 307 and 313).
- Do not forget the VAT classification on lines with VAT, with the net value as the amount.
- If the VAT return for the period has already been filed, the API documentation mentions no restriction; ask your accountant whether an amended return is needed.
Which classification counts
myDATA keeps every submission on record; the latest one counts, that is the one with the highest classification MARK.
