3784142 - Change Duplicate Invoice Check From AND to OR Condition For Supplier Invoices

• The duplicate invoice validation currently raises a warning only when all four fields match: same vendor, same invoice date, same invoice amount, and same reference (invoice number).
• Request to change the validation so that when the vendor is the same, a warning appears if any one of these matches: invoice date, invoice amount, or reference (invoice number).
• No specific error messages or error codes are mentioned.

• Product: SAP S/4HANA Cloud Public Edition
• Fiori UI for Invoice Verification (Public Cloud)

• The standard logic flags a duplicate only when all configured fields match at once (an “all-of” rule); there is no “any-one-of” option.
• The configuration lets you choose which fields are checked, but cannot change the relationship from “all-of” to “any-one-of.”
• Vendor, currency, and gross amount are always part of the duplicate check and cannot be disabled.
• If “Check Double Invoice” is not selected on the supplier, no duplicate check is performed for that supplier.
• Invoices created via automated interfaces are not duplicate-checked.

1. Note that there is no standard capability to change the duplicate invoice validation logic from an AND condition to an OR condition.
