3395075 - Supplier Invoice Duplication Check

The business need is to set duplication check for Supplier Invoices in the Create Supplier Invoice or in the Create Supplier Invoice - Advanced app.

SAP S/4HANA Cloud Public Edition (All Versions)

To avoid invoice duplication the following check has to be activated for each supplier individually in the supplier master:

• App: Maintain Business Partner (BP) ->Role: Supplier (Fin.Accounting) -> Company Code -> Tab "Vendor: Payment Transactions" -> Option "Check Double Invoice"

Furthermore the configuration of messages is also necessary in the following Configuration Step IDs:

• Define Message Types for Area M8                102091       
• Define Message Types for Area M8_2             102092

In case the requirement is to enable the duplicate invoice check for both online processing and background processing, the following message numbers need to be configured for message class M8:

M8 108 -  Check if invoice already entered under accounting doc. no. & &
M8 462 -  Check if invoice already entered as logistics inv. doc. number & &
M8 804 - Inv. not automatically created, potential duplicate exists (acc doc & &)
M8 805 - Invoice not automatically created, potential duplicate exists (inv. & &)

It is possible to set the severity of the messages of ’Error’ or ’Warning’.
