Products didn't get matched, lines are empty

The invoice got recognized, but the product column is empty in every line, even though it used to work.

The lines got recognized fine — quantities and prices are there — but the product didn't get matched in a single one of them.

Check in order#

  1. The invoice's supplier. Is it the same one the mappings were built up for? This is the cause in the vast majority of cases. Mappings are stored separately per supplier, and an invoice attributed to the wrong one looks like a blank slate.
  2. A duplicate supplier in the iiko directory. One supplier entered twice splits the mappings between them. Check the supplier list in iiko.
  3. Is this the supplier's first invoice? Then there simply are no mappings yet — the service has nothing to draw on.
  4. Was reference data synced recently? If products were added to iiko recently, the service doesn't see them yet.

How to fix it#

If the supplier is wrong — change it on the invoice header, then click Match products for empty lines in the ⋮ menu.

Important

Changing the supplier alone isn't enough. Matching runs at recognition time, not on every edit — otherwise it would overwrite your manual work. The Match products for empty lines button reruns it without touching lines that are already linked.

If this is the supplier's first invoice — link the lines by hand, or better, train the service on an old invoice right away: a hundred items in ten minutes instead of three weeks of it building up on its own.

If it's a duplicate supplier — remove the extra one in iiko, sync reference data, change the supplier on the invoice, and rematch.

To keep it from happening again#

When you pick a supplier by hand, you're also teaching the service its spelling — after two or three invoices, it starts recognizing it on its own. And duplicate suppliers are worth cleaning up in iiko once and for all: they hurt more than just ReconDoc, they hurt your reports too.
