Data Replication from S/4HANA to External Systems via AWS
Challenges/Requirements
The goal is to integrate SAP S/4HANA with external systems such as Salesforce, Concur, or SAP Ariba through middleware like AWS or Azure, rather than using SAP BTP.
Solution Highlights
SAP S/4HANA provides various standard objects, and for this demonstration, we’ve selected Business Partner data to illustrate real-time replication via AWS API Gateway. A Lambda function is employed to create corresponding records in Salesforce.
The replication process leverages the SOAP protocol to transfer Business Partner data from the SAP S/4HANA system to the AWS middleware, ensuring seamless integration.
Technical Architecture
AWS API Gateway serves as the central communication hub, efficiently managing and routing API requests between SAP S/4HANA and external applications. To ensure seamless data integration, AWS Lambda functions are employed to automatically process incoming data. These functions handle tasks such as transforming data formats and invoking API calls, ensuring that records are accurately created or updated in the target systems.
Communication Arrangement Setup in SAP S/4HANA
- Configure a webhook call [Replicate Customer from SAP S/4HANA to Client] using the scenario SAP_COM_0008 – Business Partner, Customer, and Supplier Integration.
- The Lambda function is used to connect to third-party systems like Salesforce, SAP Ariba, or Concur via their respective API endpoints.
- Once the setup is complete, create a Business Partner in SAP S/4HANA to trigger the data replication process to AWS.
To verify the success of the replication, you can use SAP S/4HANA Message Monitoring to check whether the replication was successful or failed. Additionally, the status of the record in the third-party system can be monitored using AWS CloudWatch.
Business Benefits
- Real-Time Updates
The integration enables instant reflection of data updates from SAP S/4HANA in systems like Salesforce, SAP Ariba, and Concur. This ensures consistent data across all platforms, significantly reducing the risk of errors and discrepancies.
- Lower Cost
For large organizations looking to enhance integration, leveraging AWS services such as webhooks presents a robust alternative to SAP Business Technology Platform (BTP). This approach can potentially offer greater cost-effectiveness, depending on the specific requirements of your organization.
