When a supplier sends a multi-page PDF (cover letter, terms, and invoice on different pages), Cortena can re-run extraction on only the pages you choose. That fixes wrong totals or line items without re-uploading the file.
Who this is for: AP clerks reviewing scanned or bundled PDFs where the first pages are not the invoice, or where only one section of a long document should drive extracted fields.
1. When to use page-range reprocess
Use it when:
- The PDF has more than one page and extraction clearly used the wrong pages.
- The real invoice is on page 2–3 (or the last page) of a longer scan.
- You want to avoid a full-document reprocess that might mix cover pages into line items.
Use full reprocess (all pages) when the invoice truly spans the whole document or you are unsure which pages matter.
2. Open the reprocess menu
- Open the invoice in Payables or Expenses.
- In the detail header, click the ⋯ (three dots) menu on the right.
- Choose Reprocess invoice.
If the PDF has more than one page and is not a structured e-invoice, hovering or clicking Reprocess invoice opens a page-range submenu.
3. Choose a page range
| Option | What it does |
|---|---|
| All pages | Same as a normal full reprocess |
| First page only | Pages 1–1 |
| First 3 pages | Pages 1–3 (when PDF has at least 3 pages) |
| Last page only | Final page only |
| Custom range | Enter start and end page (for example 2–4) |
Important: Page-range reprocess replaces all extracted data on the invoice with results from the selected pages only. Cortena asks you to confirm before starting.
4. Keyboard shortcut (full document only)
- Mac: Ctrl+R (not Cmd+R, which reloads the browser)
- Windows: Alt+R
The shortcut always runs a full-document reprocess (with confirmation). Use the ⋯ menu for partial pages.
5. What happens after you confirm
- The invoice shows Reprocessing… and the workflow restarts from extraction.
- Cortena slices the PDF to your page range before sending it to the extraction agent.
- When processing finishes, fields, matches, and workflow steps reflect the new extraction.
- The Activity log records the page range.
6. When page-range reprocess is not available
| Situation | Behaviour |
|---|---|
| Single-page PDF | Only full reprocess (no submenu) |
| Structured e-invoice (UBL, ZUGFeRD) | Page-range not supported · see E-invoices |
| Invoice synced to accounting | Reprocess disabled |
| Invoice in treasury payment processing | Reprocess disabled until payment completes or is rejected |
| No permission to edit | Menu item disabled |
Quick reference
| Task | How |
|---|---|
| Reprocess specific pages | Detail ⋯ → Reprocess invoice → preset or custom range |
| Reprocess entire PDF | Submenu → All pages, or Ctrl+R (Mac) / Alt+R (Windows) |
| See what was run | Activity log on the invoice |
| Structured e-invoice | Full reprocess only · page slicing does not change embedded XML |
| Synced invoice | Not available · locked after accounting export |
