The successful adoption of Enterprise Resource Planning (ERP) systems such as SAP FICO (Financial Accounting and Controlling) has become a strategic necessity for large enterprises seeking operational efficiency and financial transparency. This study investigates the complex interplay between the driving factors and the challenges encountered during SAP FICO implementation within a large corporate environment. Drawing on empirical evidence from an in-depth case analysis, the research identifies key adoption drivers including regulatory compliance, process standardization, managerial decision support, and data integration needs. Concurrently, the study highlights major obstacles such as system customization complexity, resistance to organizational change, high implementation costs, and the need for continuous user training. The findings reveal that the balance between strategic intent and operational execution determines the overall success of SAP FICO integration. Furthermore, the study emphasizes that effective change management, executive commitment, and phased implementation planning significantly mitigate the risks associated with ERP transitions. This paper contributes to both academic and practitioner perspectives by providing actionable insights into how large enterprises can navigate the technical and managerial intricacies of SAP FICO adoption to achieve long-term digital transformation objectives.
