SAP Ariba Cloud Integration Gateway

The intelligent enterprise is now more integrated than ever before. Customers are becoming more and more demanding in their integration needs, and rightfully so. In the digital age, customers want connected digital experiences across solutions and enterprises are looking to enhance the user experiences within their functions by connecting their businesses and customers to a seamless interface.

Let’s face it, in a time where everything seems to be connected, leaders in their departments are on the lookout for cloud solutions to be more agile; they want to increase collaboration, work from anywhere, and not worry about software and security updates – essentially working on what really matters to them and their clients.

As a by-product to the explosion of the number of cloud systems available today, these solutions, be it a top-notch Customer Relationship Management CRM solution or the newest peer-to-peer (P2P) software that promises to solve all your procurement needs, the integration effort is often overlooked by industry leaders.

Yes, you may have solved a critical issue that you were facing before investing in solution x, but what happens next is that this process needs to feed or be fed into another process, and this is where integration is critical.

Without a fully integrated suite of solutions, these systems will be working in silos. The same way executives and leaders of today are going all-out on challenging the silo mentality within teams and departments, integration efforts work the same way within on-premise and cloud solutions – they cannot be working in silos.

This article will introduce SAP Ariba’s latest integration solution – SAP Ariba Cloud Integration Gateway and how it promises to fulfill the big picture with regards to integration.

See the BIG picture

Every integration solution is different depending on the complexity of the enterprise; however, large enterprises most likely run hybrid solutions where cloud solutions are integrated with ERP systems deployed in either the cloud or on-premise. These companies may rely on SAP S/4HANA or SAP ERP as a single source of truth for their financial, inventory, supplier and material master data.

Before digging into what SAP Ariba Cloud Gateway is and what it offers, let us talk a little about how and where the SAP Ariba CIG fits into SAP integration efforts and give you some history on SAP’s history with regards to integration.

SAP understood early the need to build a single open platform-as-a-service platform for integrating cloud-based systems and 3rd party cloud solutions.

In 2012, SAP unveiled NetWeaver Cloud, and in 2013, the solution was reintroduced to SAP HANA Cloud Platform, which was then renamed to SAP Cloud Platform in February 2017 at the World Mobile Congress in Barcelona.

“Since the launch of our PaaS offering three years ago, it has evolved to become the digital enterprise platform of choice that enables customers, partners and developers to build differentiating solutions that intelligently connect people, things and businesses,” said Bernd Leukert, ‎member of the Executive Board of SAP SE, Products & Innovation. “To represent its breadth of capabilities, it has been rebranded as SAP Cloud Platform. This platform creates digital differentiation by connecting a rapidly growing number of smart devices and machines with people and processes to achieve superior business outcomes.”

SAP Cloud Platform is an enterprise platform-as-a-service (enterprise PaaS) that provides comprehensive application development services which lets you build, extend and integrate business applications in the cloud.

SAP Cloud Platform Integration, SAP CPI

SAP Cloud Platform Integration, or in short SAP CPI, runs on top of the SAP Cloud Platform. SAP CPI’s main purpose is to support the end-to-end process integration across cloud-based and on-premise applications between SAP and Non-SAP solutions. In short, it allows you to securely run data and business processes between two or more applications, weather on the cloud or on- premise.

SAP Cloud Platform Integration Features:

  • Out of the box integration: SAP CPI offers pre-packaged content to integrate SAP and non-SAP apps with more than 1000 pre-packaged integrations.
  • Application-to-Application, A2A Integration: Integrates end-to-end process across SAP/non-SAP and cloud/on-premise solutions.
  • Business-to-Business, B2B Integration: supports traditional EDI (Electronic Data Interchange) as well as real-time API based integrations. The solutions also support blockchain scenarios to foster trust in the network.
  • Real-time API integration: supports omnichannel access and support API to hide the complexity around heterogeneous landscapes.
  • Internet of Things, IoT Integration: Connects machines to core business processes to support real-time supply chain and digital manufacturing.
  • Web-Based solution: The platform is entirely web-based.
  • Multi-Level security: Data isolation with completely isolated tenants (memory, CPU, and database schema)

Do not confuse SAP Cloud Platform Integration with SAP PO/PI

SAP Process Orchestration (PO) and SAP Cloud Platform Integration (CPI) are, respectively, on-premise and cloud-based integration platforms that allow the synchronization of data between different systems to streamline business processes.

While all are considered middleware tools, think of SAP Process Orchestration and SAP Process Integration as the big brothers to SAP CPI. SAP PO was released in 2002 within the realm of the notoriously famous XI – Exchange Infrastructure offered by SAP.

Deciding between the two solutions can be cumbersome to solution managers but think about it this way: the SAP CPI platform is growing everyday with pre-packaged solutions and integrations. It is entirely cloud based, no need to worry about security and updates. It all depends on your current array of solutions today and your needs in the future. SAP PO is 16 years old, and SAP CPI is still evolving.

The question that you might ask is: But what will happen to SAP PO/PI in the future? SAP is still offering and supporting the two solutions and depending on your long-term plans with regards to investing in Cloud Applications, you can still rely on SAP PO/PI for your integration.

However, if your current array of solutions consists of cloud applications (think Concur, SAP Ariba, SuccessFactors, Fieldglass, and now Qualtrics) that will need to be further integrated with your on-premise SAP ERP or in the cloud with SAP S/4HANA, then SAP CPI needs to be brought to the table.

Again, it all depends on your design and your solution architecture and more importantly your long-term goals with regards to integration.

Take away

Cloud-cloud = SAP CPI
On prem-On prem = SAP PO
On prem – cloud = Either SAP CPI or SAP PO/PI or both

SAP Ariba Cloud Integration Gateway, SAP Ariba CGI

In a simple example, a Purchased Order issued in SAP Ariba, follow-on processes, such as payment, invoice verification and inventory management updates might occur on the backend ERP or S/4HANA. To achieve true seamless data update between the two systems, multiple integration points will have to be set up.

SAP Ariba CIG relies on SAP CPI for the mapping, transformation and messaging. For incoming calls SAP Ariba CIG relies on HTTPS, and the Cloud Connector via the SSL connector for outgoing calls as shown in the figure above. You may also use SAP PI/PO, or SAP CPI as an integration middleware layer as shown in the figure above.

Once deployed and integrated with SAP Ariba, CIG provides easier browser access, quick and scalable upgrades by eliminating or largely reducing manual steps and increase the speed of procurement process all while enforcing compliance.

Another benefit to SAP Ariba CIG is testing, SAP Ariba CIG provides self-service testing scripts through Test Central, which provides users the ability to test and deploy at their own pace in a centralized web-access environment. Test Central also comes with pre-defined standard test-cases to expedite the integration testing process.

SAP CIG Add-on Types

There are two available pre-packages depending on your SAP environment, SAP Ariba Cloud Integration Gateway add-on for both SAP ERP and SAP S/4HANA. Both add-ons are available from the SAP Service Marketplace from SAP ONE Support Launchpad.
