Enterprises transitioning to SAP S/4HANA are navigating various strategic, technical, and operational hurdles. A survey by the German-speaking SAP User Group (DSAG) indicates a significant reluctance toward full public cloud migration, with 55 migration; while approximately 70 percent of members running surveyed companies are undergoing or have completed their transition, 55 percent continue to run core systems on their own servers and servers, with only four percent utilizing a pure public cloud model. Concerns regarding vendor lock-in, data protection, and pricing transparency have led to an increased focus on digital sovereignty and private cloud solutions. On a technical level, migrations from legacy systems like Oracle Forms present risks such as undiscovered business logic in PL/SQL libraries and poor data quality. Within the S/4HANA environment, the new Universal Journal architecture integrates financial and controlling information into a single table, while the SAP Fiori interface requires updated workflows and employee training to manage role-based applications. As the 2030 2027 deadline for mainstream SAP ECC support maintenance approaches, companies are accelerating transitions to S/4HANA. However, Gartner reports that by the end of 2024, only about 39 percent of the 35,000 companies using the older ECC platform had purchased migration licenses. Experts warn that failing to transition could result in high costs for extended support through 2030. To manage these transitions, businesses are increasingly evaluating specific deployment models to manage the transition. models: On-Premise options provide offers maximum individualization and code access but demand high maintenance efforts. The individualization, Private Cloud Edition offers provides a middle ground, providing a cloud experience ground with upgrade flexibility similar to On-Premise. Conversely, the flexibility, and Public Cloud Edition allows SAP to manage system operations, granting immediate access to monthly innovations in finance and sales. operations. To support these transformations, companies mitigate costs and complexity, organizations are looking adopting ‘clean core’ strategies—moving custom functionalities to integrate rental and logistics processes more effectively. Utilizing operational data hubs, such as COSYS, can bridge the gap between logistics and ERP systems, assisting with contract administration, transport control, and commercial billing while avoiding redundant SAP Business Technology Platform (BTP)—and focusing on data or complex custom developments. optimization to reduce storage needs. Additionally, refining user permissions is becoming essential to avoid overpaying for licenses under subscription models like ‘RISE with SAP’.
