SAP S/4HANA Integration with Ariba || Part 3 ||

By /

Welcome to this comprehensive and informative series on SAP S/4HANA Integration with Ariba.This is S/4HANA Integration with Ariba Part 3 before diving into this topic please refer S/4HANA Integration with Ariba Part 2.

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

This series is divided into multiple parts, so before reading any specific integration topic, it is my humble request that you go through the previous parts first for better understanding. Until and unless you understand the earlier parts, you may find it difficult to follow the upcoming integration topics.

Note – This integration is also valid for SAP ECC system

SAP S/4HANA Integration with Ariba Integration – Prerequisites

As you know, in the second part of our integration series, we discussed the installation of the Cloud Connector, which is an activity handled by the Basis team. However, after the installation, the configuration of the Cloud Connector becomes the responsibility of the CIG consultant.

But what exactly does Cloud Connector configuration mean?
The Cloud Connector acts like a secure firewall or gateway. All inbound data—that is, data flowing from CIG to S/4HANA—passes through the Cloud Connector. Therefore, we need to configure connections for both CIG and S/4HANA in the Cloud Connector so that secure communication can be established between the two systems.

A common question that may arise is:
Why do we use the Cloud Connector for the CIG → S/4HANA flow and not for the S/4HANA → CIG flow?
The answer is simple. For the S/4HANA → CIG (outbound) flow, we already use SSL certificates to establish trust and secure communication between S/4HANA and CIG. Because of this, the Cloud Connector is not required for the outbound flow.

Enable CIG

Before moving to the Cloud Connector configuration, we must first enable CIG. As you know, CIG (Central Integration Gateway), now called “Managed Gateway for Spend Management and SAP Business Network,” is the SAP tool responsible for integration between S/4HANA and Ariba. Below are the steps to enable CIG so that it can be used for the integration.

Enable CIG for Ariba Sourcing and Ariba Buying and Invoicing

  • Log in to the SAP Ariba Dashboard.
  • Go to Manage → Administration for Ariba Sourcing.Core Administration for Ariba Buying and Invoicing

  • Under Integration Manager, select Managed Gateway for Spend Management and SAP Business Network.

  • Choose the appropriate Data Center.
  • Select the checkbox for SAP Integration Suite – Managed Gateway for Spend Management and SAP Business Network.
  • Accept the terms by selecting “I have read and agree to all terms and the Ariba Privacy Statement.”
  • Select all required tasks and click Save.

After enabling CIG, you will receive the CIG P-User and password on your registered email address. You can then activate the account using those credentials. This is how CIG is enabled and made ready for use in the integration.

Enable CIG for SAP Business Network

  • Log in to SAP Business Network (ariba.buyer.com).
  • Click on the Profile icon and select Settings.

  • Under Integration, choose SAP Integration Suite – Managed Gateway for Spend Management and SAP Business Network Setup.

  • Click on Enable Managed Gateway for Spend & Network.
  • Select the appropriate Data Center and click Save.

After enabling CIG, you will receive the CIG P-User and password on your registered email address. You can then activate the account using those credentials. This is how CIG is enabled and made ready for use in the integration.

Cloud Connector Configuration

  • Once you install cloud connector login with the user credentials provided during the installation
SAP S/4HANA Integration with Ariba Integration

  • When you login for the first time you will not see any Subaccounts in the connector page. You need to add separate sub accounts for test and production system. Click Add Subaccount button.

Cloud Connector Configuration
  1. Region Host: Any customers integrating via CIG, will use one of the below data centers depending on their location or when the CIG was
    activated. If you using CIG EU, then its eu1.hana.ondemand.com, if you are using CIG US, then its us4.hana.ondemand.com, if are
    using CIG CN, then its cn1.platform.sapcloud.cn, If you are using CIG KSA then its, sa1.hana.ondemand.com, If you are using
    CIG UAE then its, ae1.hana.ondemand.com,
  2. Subaccount: We have separate Subaccounts for TEST and PRODUCTION systems for each DATA CENTER. Follow the below table to know what Subaccounts are to be added in SAP CC for your data center. This is common for any customer. All the sub-accounts should be added for which ever data center you are connecting to.This Subaccounts are works like load balancer and these Subaccounts already provided by CIG.
  1. Display Name: You can provide any display name to any value. Here I used CIG_TEST
  2. Subaccount User/Password: Provide the CIG PUser and Password value you have received in email when you enable
    CIG and the corresponding password.
  3. Location ID: Provide a location id value here. It can be anything but make sure you provide the same
    in the CIG portal connection details and for other Subaccounts. Here I am using ARIBACIG
Cloud Connector Configuration
  • In the configuration page, If you want to use any proxy, you can mention that as well. Check with your BASIS/IT consultant if this is required. My proxy is proxy.ariba.com so I used it here. Please use your own proxy server.
Cloud Connector Configuration

  • Click on the sub account you created recently and make sure the details you provided in the previous step are reflecting here. This shows a secure tunnel is established between CIG sub account and the cloud connector.

  • Click Cloud To On-Premise link to provide the virtual mapping to the internal system. When you configure for the first time you will not see any entries here. Click on the ‘+’ sign to add virtual mapping.
Cloud Connector Configuration

  • Select the Back-end Type as ABAP System if you are using SAP ECC or S/4 HANA system and click Next

  • Select the Protocol as HTTP or HTTPS. We recommend to choose HTTPS

  • Provide the Internal Host and Port of your SAP Application server. You can get this details from tcode SMICM. SMICM->Goto->Services. Click Next

  • Provide the Virtual host and Virtual port details. You can provide any value for virtual host and port but make sure it is a fully qualified domain name and not the same value as the internal host / port. We will provide the virtual host value in the CIG Portal connection page.
  • Note: Make sure your virtual host should not have any underscore character otherwise, you will see a 400 error when sending the message from CIG.

  • Choose the Principal Type as None

Till this point, we are covering the SAP Ariba Integration prerequisites, and the next few parts will complete these prerequisites. After that, we will move on to the actual integration configuration. Once again, it is my humble request that you go through all the previous parts of the integration series, as it is mandatory. Only then will you be able to understand the integration configuration more clearly, quickly, and without confusion.
