DSN - Duplicate Invoice Posting

[TSoon]

Hi experts,

With DSN, we understand that supplier can create Order Confirmation, Shipping Notification, and Invoice creation in Ariba Network.

I have scenario below which needs clarification:

PO is created in SAP ERP. Order confirmation and shipping notification is received from Supplier thru DSN. GR is done by Buyer in SAP ERP. And the hardcopy of the invoices are received by AP department which then subsequently entered in SAP ERP with invoice posting with reference with the PO.

Question 1: With the invoice document posted in SAP ERP, can the Supplier still able to post invoice against the same PO?

Question 2: With DSN, can invoices be posted from SAP ERP instead of from supplier via Ariba Network?

Thanks.

Hi,

Another scenario is supplier will use the DSN functionality up to shipping notification but somehow they will send hardcopy invoice. Will DSN still show that there are invoices to be billed?

Thanks.

DSN will not show that.

You can use PDF Invoicing functionality (suppliers sends a PDF to email)

Or you can advice suppliers to attach the invoice to ASN document and it will show as attachment in SAPs inbound delivery doc.

hi!

1) Supplier can submit an invoice against a PO because technically PO is not yet invoice from his perspective (invoice only exists in SAP). The submitted invoice will reach SAP, it will go there through 3-way match and fail. The failure will result in invoice showing as rejected on Ariba Network to the supplier.

2) Yes, invoices created/inputted in ERP can be replicated onto Ariba Network. We usually call such an invoice "CC invoice" (CC=carbon copied) or "erp-initiated" invoice. To see how to configure such a transaction please see the following link:

CC invoice

Having configured this transaction will solve the problem from question 1).

Because PO will show as invoiced, and supplier will not be able to over invoice, unless transaction business rules allow that to happen for some reason.
