Introduction

SAP S/4HANA is a next-generation, integrated enterprise resource planning (ERP) system that leverages the power of SAP HANA, a high-performance in-memory database. With the growing demand for flexibility and efficiency, SAP offers two deployment options: On-Premise and Cloud. To facilitate seamless integration and customization, SAP provides Software Development Kits (SDKs) for both environments.

In this blog, we will explore how to use the SAP S/4HANA SDK to access and manipulate data from both On-Premise and Cloud deployments. We will focus on the Business Partner API as an example to demonstrate these capabilities.

Understanding the SAP S/4HANA SDK

The SAP S/4HANA SDK is a comprehensive toolkit designed to enable developers to build, extend, and integrate applications with SAP S/4HANA systems. The SDK provides a consistent set of APIs and tools to interact with the core functionalities of SAP S/4HANA, regardless of the deployment model.

  • On-Premise SDK: This SDK is tailored for on-premise deployments, offering robust tools for deep integration with existing infrastructure.
  • Cloud SDK: Designed for cloud deployments, this SDK focuses on scalability and ease of integration with cloud-native services.

Both SDKs provide similar functionalities but are optimised for their respective environments.

Setting Up the SDK

Prerequisites

  • SAP S/4HANA system (On-Premise or Cloud)
  • Developer account with appropriate permissions
  • Development environment (e.g., Eclipse, IntelliJ)

Installation Steps for On-Premise and Cloud SDK

  1. Access the SAP Accelerator Hub.
  2. Navigate to either Cloud Edition or S4HANA (On-Premise).
  3. Select API from the main tab, then All in the secondary tab.
  4. Search for Business Partners.
  5. Choose Business Partner (A2X) (V2).
  6. Click and open the service.
  7. On the Business Partner Service page, locate the section titled API Resources at the bottom.
  8. Select the API Specification option.
  9. Download the EDMX file in JSON, YAML, or EDMX format.
  • SAP Accelerator hub

  • Navigate to this

  • Search

  • Business partner

  • Navigate Down and download the EDMX file

Utilising the EDMX File

On the Business Partner Service page, navigate to the API consumption tab.

For Java

  • Set up a plugin in the xml file.
  • When the Java application is triggered, it will build the required files to use the SDK.
  • Java SDK Documentation

For JavaScript

Note: For both Java and JavaScript, ensure the EDMX file is placed in the appropriate project folder. For Java, place it inside the resource folder; for JavaScript, place it in the root folder.

How to Use the SDK

How to GET Business Partner

  • Step 1 : You Need to Setup Destination in ENV.
  • Step 2 : Access the Destination by using the Destination Accessor.
  • Step 3 : Initialise “ BusinessPartnerService ” this will have the url endpoint of the required API Service in your on-premise or cloud.
  • Step 4 : Make the Request by using the Destination.
  • Step 5 : Almost All the On-premise system and cloud system is private, so you will need to step up header to have authentication credentials.
  • Eg : getBusinessPartnerById(“BP_ID”)

Follow the SAP Provided Documentation to find out how to do Create, Updata, Delete, Filter etc…

Conclusion

In this blog, we have covered how to use the SAP S/4HANA SDK to access and manipulate data from both On-Premise and Cloud deployments, using the Business Partner API as an example. By following the steps and best practices outlined, you can effectively integrate and extend your SAP S/4HANA system to meet your business needs.
