Recognize Suppliers on Incoming Documents

Every document that arrives from the Peppol network gets a row on the Incoming Supplier Recognition page, showing which vendor it was matched to and how. When nothing could be matched, you assign the vendor there, and the sender's Peppol identity is registered so later documents from the same supplier match on their own.

This matters more than it sounds. Without a matched vendor there is no automatic G/L coding at all, and a new e-document is created on every poll for the same supplier.

Open the list

Choose the Search icon, enter Incoming Supplier Recognition, and then choose the related link. It is also on E-Invoice Platform Setup and on the vendor card, as Incoming E-Documents from This Vendor.

A row shown in red will not import. Read the Will Not Import column, fix what it names, then choose Rematch.

How a supplier is identified

The Matched On column tells you which identifier produced the match. Each rung requires exactly one candidate — if two vendors answer, nothing is assigned.

Ambiguity is deliberately left alone rather than guessed:

More than one vendor answers to this supplier identity (n candidates). Nothing was assigned, because attaching a supplier's bank details to the wrong vendor is the failure this list exists to prevent.

Assign a vendor by hand

1. Select the row with no vendor.
2. Choose the Assign Vendor action and pick the vendor.
3. Answer the question about registering the Peppol address.

After assigning, you are asked:

Vendor number is now linked to this document. Also register the Peppol address id on the E-Document Service, so Business Central recognises later documents from this sender by itself?

Answer yes unless you have a reason not to. That registration is what stops you doing this again next month. It writes to a standard Business Central table, and Prepare for Uninstall reports and removes it.

Assigning also fills in the vendor's Peppol Endpoint if it was still blank.

If the supplier already sends from a second address you have registered elsewhere, the registration is refused rather than overwritten — a supplier sending from two Peppol addresses is a real case, and which one wins is a decision for a person.

Correct or remove a registration

If you registered a Peppol identity against the wrong vendor, choose Remove Peppol Id on the row. The registration goes; the row itself stays, because it is the record of what was decided. You can then assign the right vendor and register again.

Register Peppol Id does the same job on its own, without going through Assign Vendor — use it on a row whose vendor is already right but whose identity was never registered.

The registrations themselves live on the standard Service Participants page, which Service Participants on this list opens.

Re-run the identification

After you fill in a Peppol endpoint or an enterprise number on a vendor card, choose Rematch on the row. The identification runs again and the row updates.

The supplier's own attachments

Suppliers often embed their own PDF of the invoice in the electronic document. Those are copied onto the purchase document Business Central creates, where the Supplier Document box previews the first page and Open Document downloads it.

The Supplier Attachments column records what happened, including anything that was too large to copy — named rather than dropped in silence. See Where Supplier Documents Are Stored.

What happens next

A matched document still needs two more things decided: whether it becomes a purchase invoice or a purchase order, and whether its lines resolve to G/L accounts.
