Designing Remote Function Call on SAP S/4HANA to Support Process Automation and Data Synchronization in Human Resource Management

Large companies are supported by implementing various information technologies for specific functions across different departments. These information technologies require a seamless flow of data to optimize business processes. Companies often face challenges in data management, particularly data inconsistencies within their information systems, including large volumes of employee data managed by the Human Resource (HR) department. The lack of data integration across systems is a critical issue that must be addressed, especially between SAP S/4HANA application and external websites. This research aims to design a communication protocol based on Remote Function Call (RFC) to support the automatic and real-time synchronization of employee data in the HR Department. Taking an Indonesian state-owned enterprise as its case, this research was carried out in the latter half of 2024. The methodology used is SAP Activate, which supports flexibility, scalability, and focuses on best practices in implementing SAP solution projects. The integration system was evaluated through System Integration Testing (SIT), utilizing dummy data to simulate synchronization across different information technologies. The test results indicate that the RFC design has successfully facilitated data synchronization within the HR Department. The conclusion of this study affirms that the design of RFC communication protocol developed effectively supports smoother process automation and opens opportunities for the development of similar data communication systems for other purposes or functions in the future.
