What configuration requires

Credit notes received as PDF email attachments do not require separate activation. The standard PAYABLES AG. – RUN permission set already includes permission to create purchase credit memos. Where permissions or profiles have been customized, Microsoft says to check that they allow access to these documents and the draft’s application fields. This is documented in the setup guide.

Invoices and credit notes use different controls

The distinction concerns the document each draft relates to. Microsoft separates invoice matching to purchase orders from credit-note application to posted invoices.

For invoices, matching warnings represent Business Central checks on quantities, receipts, units or prices. They are not AI confidence scores and do not initiate an approval workflow by themselves.

What to review before finalizing a credit memo

Business Central suggests an invoice when it finds exactly one open posted invoice for the pay-to vendor that matches the reference in an applicable currency. Distinguish Applies-to Vendor Inv. No., the vendor’s reference, from Applies-to Doc. No., the document selected for application. Multiple matches require manual selection. Application rules.

The supervisor can correct the reference or selection; the agent does not change these fields. Without a selected invoice, the credit memo remains unapplied when posted, even with Apply to Oldest. Finalization creates an unposted credit memo that must be reviewed before posting. Credit-note review.

Availability: country, language and version

Microsoft places Copilot and agents in Business Central online. The version 27.1 release notes already listed Payables Agent as generally available; they do not establish the minimum version for the credit-note processing now described.

The availability table lists all countries and regions and includes Spanish for Spain and Mexico. However, the agent overview still states that validation and support are English-only. The sources are inconsistent on this point.

This article therefore does not confirm Spanish-language credit-note processing for a particular environment. The FAQ also makes some deployments conditional on allowing data movement across geographies.

Operational limits

Microsoft limits PDFs to 10 pages and 5 MB, and skips emails with more than 10 attachments. It publishes daily limits of 100 emails and 500 invoices, without specifying a separate credit-note quota. Supervisor confirmation is distinct from a Business Central approval workflow. Limits and oversight.

Using the agent consumes Copilot Credits and can incur charges. Agent billing.

Synthetic example

A fictional vendor sends a €1,000 invoice linked to a purchase order and, after it is posted, a €100 credit note referencing it. For the invoice, the reviewer would check order lines and receipts. For the credit note, the reviewer would check the selected open invoice and proposed application. These figures illustrate two different reviews; they represent neither a Nexo test nor a guaranteed automatic outcome.

Nexo’s interpretation

The practical implication is to review permissions alongside supervisor responsibilities. A customized implementation should include test cases for credit notes with missing references, ambiguous references and a different currency. This is an editorial recommendation for test preparation: success with an invoice does not, by itself, demonstrate that credit-note processing has been validated.
