When you correct an extracted field on a costs or sales document, Dext automatically logs that change as a reported mistake. You don't need to report it manually - the correction itself is the feedback.
Dext uses these corrections to improve its machine learning algorithms and extraction accuracy over time.
Bank statement extraction errors
Bank statement extraction works differently. If the extracted data looks incorrect, you need to report the mistake manually so Dext can resubmit the statement for reprocessing.
To report a bank statement extraction error, see How to use Bank Statement Extraction in Dext.
Supplier statement extraction errors
For supplier statements, select Report mistake on the statement's details page.
Reporting a mistake on a supplier statement excludes it from your processed item count. You'll also no longer be able to view extracted line items, mark it as reconciled, or send paperwork requests for that statement. Try re-submitting the item first - if the issue persists, then report the mistake.
For full details, see Reconcile supplier statements in Dext.
