HOW-TO

How to stop paying a supplier invoice twice in S/4HANA

Short answer

Before you enter a supplier invoice in S/4HANA, search the supplier's bills for the same number or amount. Use one reference format and check the payment run for repeats.

Duplicate payment is when the same supplier invoice is entered or paid more than once. It often happens when an invoice arrives by two routes.

Before you start

  • Check Double Invoice indicator set on the supplier

The S/4HANA way

Where to find it: Business partner (role Supplier, Financial Accounting) > Company Code > Vendor: Payment Transactions > Check Double Invoice

  1. In Maintain Business Partner tick Check Double Invoice on the supplier company code data.
  2. Always enter the Reference when you enter the invoice. The check runs only if the reference is entered.
  3. SAP compares supplier, currency and gross amount. Your admin can also switch on Company code, Reference, Invoice date and Credit memo.
  4. A match gives a warning or an error, as set in Customizing (Set Check for Duplicate Invoices).

Limits in S/4HANA

  • If a document is cancelled and entered again, no message shows.
  • Supplier, currency and gross amount are always checked. The reference and date checks depend on configuration.

Words S/4HANA uses

  • Business partner. The single master record for a supplier or customer in S/4HANA.
  • Company code. A legal entity with its own books.

The Pulsify way

  1. Forward the supplier's invoice to Pulsify.
  2. Pulsify compares the invoice number with punctuation and case ignored, plus the same supplier, invoice date or tax ID.
  3. It checks other Pulsify documents and active bills in S/4HANA.
  4. A possible duplicate is flagged. Open the match, then reject or approve anyway.

What Pulsify does not do here

  • Pulsify flags. You decide.
  • A duplicate with a quite different invoice number may not be found.

Common mistakes

  • Leaving the Reference blank, so the check does not run.
  • Expecting a message when a cancelled invoice is entered again. None shows.
