Purchase Order and Invoice Collaboration Using the Ariba Network

Ariba Network Integration enables you to collaborate in SAP S/4HANA with your suppliers via the Ariba Network. You can send electronic purchase orders to your suppliers, and you can receive purchase order confirmations, advanced shipping notifications, and electronic supplier invoices from the Ariba Network. You exchange the data using cXML messages.

High-Level Overview of the Purchase Order and Invoice Collaboration Process

The following table explains the process steps and the cXML message types used in each process step:

Invoices with errors can be saved with errors and can later be processed manually.	InvoiceDetailRequest
Sending CC invoices	You can create invoices, for example invoices you receive on paper, in SAP S/4HANA on behalf of your suppliers. These invoices can be transferred to the Ariba Network as CC invoices.	CopyRequest.InvoiceDetailRequest
Sending status updates for invoices	Status updates for received invoices and for CC invoices are sent to your suppliers via the Ariba Network. For example, when an invoice is posted, paid, or canceled, or when a blocked invoice is released, a status update is sent.	StatusUpdateRequest

Connectivity Options

There are three ways of connecting SAP S/4HANA with the Ariba Network:

Direct connectivity: You establish a system connection between SAP S/4HANA and the Ariba Network without using middleware.
Mediated connectivity using HCI: You establish a system connection using SAP HANA Cloud Integration between SAP S/4HANA and the Ariba Network.
Mediated connectivity using PI: You establish a system connection using middleware between SAP S/4HANA and the Ariba Network.

Options for Connecting SAP S/4HANA with the Ariba Network

For mediated connectivity, the Ariba Network Adapter for SAP NetWeaver is required. For information about which version is relevant for the functions you want to use, see SAP Note 1991088.
