Additional invoice reference and parallel invoice number

The invoice number may not always be sufficient as a reference. Depending on country-specific requirements, a government-issued identifier may be required for domestic trade, while some countries commonly use a GUID to facilitate electronic payments.

Configuration options

You can capture invoice references with different labels using flexible configuration options. The standard process stores invoice references in the Parallel Invoice Number (PAIN) field in M3.

However, you can choose between two methods to store the invoice reference:

  • Parallel Invoice Number (PAIN)
  • Additional Reference Number (Ref 1-3)

Different methods are used in different countries.

To enable a more flexible setup:

  1. Set the enablePaymentReferenceBR RPA argument to true.
  2. Use the ION business rule M3InvoiceProcessing_PaymentReference_BR.

You must configure this rule based on the applicable country localization fact sheets.

Configure these parameters In the business rule:

  • Division
  • Country: Supplier’s country
  • Invoice labels
  • Payment reference method:
    • Parallel Invoice Number
    • Invoice Reference Number

See Business rule configuration and dynamic matching logic.
