Welcome to this comprehensive and informative series on SAP S/4HANA Integration with Ariba.
This is Cloud Integration Gateway (CIG) Overview blog, before diving into this topic please refer S/4HANA Integration with Ariba Part 9

In this integration journey, I have explained the complete end-to-end configuration required to integrate S/4HANA with all solutions of Ariba for smooth and accurate data transformation.

This series is divided into multiple parts, so before reading any specific integration topic, please ensure you have gone through the previous parts for better understanding.

Note – Before diving into any Ariba integration chapter, ensure you have reviewed the functional scenarios and are familiar with all documents and interfaces for that specific solution.
This integration is also valid for SAP ECC system.

We have covered the prerequisite configurations required for S/4HANA integration with SAP Ariba.

Next, we will dive into the solution-specific configurations; however, before we begin, it is essential to understand the Managed Gateway for Spend & Network (formerly known as Cloud Integration Gateway or CIG).

CIG is the primary integration tool responsible for connecting S/4HANA and Ariba.

In this section, I will provide a high-level overview of the CIG platform and explain the purpose of its various features. If you don’t fully understand all the CIG platform features right now, don’t worry. As we move into the Ariba solution-specific integration, we will be using these features anyway, so you’ll definitely get the hang of them then. For now, a high-level overview of CIG is more than enough.

Cloud Integration Gateway (CIG) Overview

Log in to Ariba Realm —-> Go to Manage —-> Choose Administration —–> Under Integration Manager select Managed Gateway for Spend&Network —-> Click on Visit the SAP Integration Suite, managed gateway for spend management and SAP Business Network

After following the navigation path above, you will be directed to the CIG Portal.

Home

On the Home Tab of CIG, you can create new integration projects. You can also monitor the status of your projects—whether they are in Testing or Production. Additionally, this tab shows a summary of your transactions, including how many have completed successfully or failed.

My Configuration

Project

The Integration Project that a user creates in CIG establishes both inbound and outbound connectivity between S/4HANA and Ariba.
In the Project section under My Configurations, you can view the status of your integration projects.

Connections

In the Connections section you can monitor or edit the connections details which you have added in the integration project.

Mappings

In the Mappings section, User can do the custom mappings for different transactions.

Authorization

In the Authorization section you will find CIG PUSER and PUSER Email. User can also change PUSER and Email from here.

Connectivity Tool

With the Connectivity Tool, you can test the connectivity inbound and outbound to the managed gateway with your back end SAP system. The outbound option is to test connectivity from the managed gateway to your back end system. The inbound option is to test connectivity from your back end system to the managed gateway by providing the IP Address of the back end system.

Transaction Tracker

Transaction Tracker is one of the most important and highly used menu of CIG.
It’s a simple tool that helps you find and monitor your documents using different search filters. You can even download your search results as a CSV file.
The tracker shows if a document was successful or if it failed. If there’s an error, it will show you exactly what went wrong. Once you fix the problem, you can reprocess the failed document right from the tracker. You can also download the data (payloads and attachments) if you need to look at them more closely.

If a transaction fails, you can also find the root cause or the possible reason for the failure here.

Resources

• In the resources section user can download the SSL certificate which is require to maintain in the S/4HANA system to enable trust between Ariba and S/4HANA.
• Mapping specifications show you how information moves from one system to another. They show which field in the ‘source’ matches which field in the ‘target.’ You can use these to understand how the data is connected, but you cannot change the standard settings yourself.

With that, we have covered the high-level overview of the CIG menus. In this chapter, I have focused only on the most important menus that are frequently used in real-time operations.

One important note: Cloud Integration Gateway (CIG) is now officially known as SAP Integration Suite, Managed Gateway for Spend Management and Business Network. However, most consultants still call it ‘CIG’ for simplicity. To keep things easy, we will also continue to use the term CIG throughout our integration journey.
