INTRODUCTION
SAP Ariba is one of the most widely used enterprise procurement platforms worldwide.
For suppliers working with large organizations, supporting SAP Ariba PunchOut integration is often a mandatory requirement to enable compliant purchasing and real-time catalog access.
This guide explains how SAP Ariba PunchOut works, which standards are involved, and what suppliers need to consider when integrating their e-commerce platform with Ariba.
What Is SAP Ariba PunchOut?
SAP Ariba PunchOut allows buyers to access a supplier’s online catalog directly from the Ariba procurement interface.
Instead of managing static catalogs, buyers punch out to a live supplier catalog, select products, and return the shopping cart to SAP Ariba for approval and order processing.
Which PunchOut Standard Does SAP Ariba Use?
SAP Ariba primarily uses cXML (Commerce XML) for PunchOut integrations.
cXML defines how PunchOut sessions are initiated, authenticated, and how carts are returned to Ariba.
SAP Ariba PunchOut Integration Flow
1. Buyer launches the supplier catalog from SAP Ariba
2. Ariba sends a PunchOutSetupRequest (cXML)
3. Supplier validates the request and opens a session
4. Buyer shops on the supplier catalog
5. Cart is returned via PunchOutOrderMessage
6. Approval and order creation continue in Ariba
