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.

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:
Process Step |
Details |
cXML Message Type |
|---|---|---|
Sending purchase orders |
You can send purchase orders as well as changes to purchase orders or cancellations from SAP S/4HANA to the Ariba Network. The following item types are supported:
Purchase orders can be transferred including the attachments they have at header level. |
|
Receiving purchase order confirmations |
You can receive purchase order confirmations from your suppliers via the Ariba Network. |
|
Receiving advanced shipping notifications |
You can receive advanced shipping notifications from your suppliers via the Ariba Network, which creates inbound deliveries in SAP S/4HANA. |
|
Receiving invoices |
You can receive invoices from your suppliers via the Ariba Network. The cXML message also transfers a PDF version of the invoice. The transfer of additional attachments is also supported. Error-free invoices can be posted automatically in SAP S/4HANA. Invoices with errors can be saved with errors and can later be processed manually. |
|
Sending status updates for invoices |
Status updates for received 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. |

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
.
For the baseline setup of the integration between SAP S/4HANA and the Ariba Network, we recommend that you use SAP Activate and SAP Best Practices. For more information, see . If your requirements exceed the baseline setup, use the SAP Customizing Implementation Guide in the SAP S/4HANA system.
