Supplier mismatch between invoice and purchase order

You may encounter scenarios where the supplier listed on the invoice differs from the supplier on the originating Purchase Order (PO).

For example, this scenario can happen when invoices are issued by a parent organization, a logistics provider, or an alternative billing entity.

To ensure accuracy and maintain financial control, you can use a controlled handling mechanism designed for these scenarios.

By default, when you process an invoice and a mismatch is detected between the invoice supplier and the purchase order supplier:

  • The invoice is not processed automatically
  • The invoice is routed to the Review Center under the Validation Error tab.

Resolving supplier mismatch

If the supplier on the invoice does not match the purchase order, update the supplier in the Review Center. This process ensures that supplier selection is an intentional, user-driven decision.

  1. In the Review Center, select the invoice.
  2. Select the Header tab.
  3. In the Supplier source selection field, select the supplier option:
    • Invoice Supplier: Processes the invoice under the billing entity
    • PO Supplier: Aligns processing with the purchase order
  4. Review the updated invoice details.
  5. To submit the invoice for continued processing, click Submit.
    This list shows the processing behavior after correction:
    • The selected supplier is applied before the invoice is transferred to M3.
    • The invoice proceeds through standard validation and posting.
    • The supplier information is not overridden.
