What is SAP S/4HANA?
SAP S/4HANA is the latest generation of ERP from SAP and is based on the powerful SAP HANA in-memory database. It was developed as the successor to classic SAP ERP systems (such as SAP ECC) and enables companies to control, analyze, and optimize their business processes in real time.
SAP S/4HANA is a central ERP system that integrates all areas of the company, including financial accounting, controlling, procurement, production, sales, and customer management. Compared to previous SAP versions, this iteration features a streamlined data structure, enhanced processing speed, and an intuitive user interface (SAP Fiori).
SAP's introduction of SAP S/4HANA responds to the growing demand for digital business models, automation, and cloud technologies. This is not merely a technological upgrade; it is a strategic step for companies that wish to modernize their ERP landscape and adapt it to the challenges of digital transformation.
Technical basics and deployment options of S/4HANA
SAP S/4HANA is based on the modern in-memory database SAP HANA, which enables real-time data processing and significantly accelerates complex analyses. In contrast to classic ERP systems, S/4HANA reduces redundant data structures and optimizes business processes through a simplified architecture. This is complemented by the SAP Fiori user interface , which offers an intuitive and role-based user experience on all end devices.
When implementing S/4HANA, companies can choose between different deployment options: SAP Cloud ERP, SAP Cloud ERP Private, and SAP S/4HANA On-Premises. This flexibility allows you to customize your IT strategy to meet your business's specific needs.
Please consult our detailed report on SAP S/4HANA deployment options to determine the most suitable version for your company.

Modern core areas with SAP S/4HANA Enterprise Management
SAP S/4HANA focuses on SAP S/4HANA Enterprise Management, which maps all end-to-end core processes of a company in a single integrated solution. It integrates proven standardized ERP functionalities with modern technologies such as Artificial Intelligence (AI), Machine Learning, and Automation to enhance business processes.
As the successor to SAP Business Suite, SAP S/4HANA Enterprise Management builds on successful modules such as SAP ERP (ECC), CRM, SRM, and SCM, combining them into a simplified, powerful platform.
The solution offers comprehensive core functions in areas such as finance, logistics, sales, procurement, and production, which are significantly accelerated and optimized by the real-time processing of the SAP HANA database.
SAP S/4HANA replaces the complex data models of the classic Business Suite with a simplified and uniform architecture. The result is faster business processes, greater efficiency, and an improved basis for data-driven decisions in real time.
Advantages of transitioning to SAP S/4HANA
The switch to SAP S/4HANA is essential for companies to remain future-proof and benefit from a modern, powerful ERP platform. The advantages of a transformation at a glance:
Enhanced efficiency and accelerated processes: Simplified data structures and optimized workflows reduce complexity and improve performance.
Automation & AI integration: Built-in machine learning and AI capabilities enable intelligent processes and reduce manual tasks.
Intuitive user interface with SAP Fiori: Modern, role-based dashboards provide a superior user experience and enhance productivity.
Cloud and hybrid options: Choose between on-premise, cloud, or hybrid models and flexibly adapt your IT strategy.
End of SAP ECC support: Regular support for SAP ECC will expire within the next few years, making early migration necessary.
Future-proofing & innovation: SAP S/4HANA lays the foundation for digital transformation, IoT applications, and scalable business models.
Implementing a successful S/4HANA transformation
Switching to SAP S/4HANA offers many advantages, but also presents challenges that should be addressed early on. Complex data migrations, process adjustments, and change management are just some of the challenges that must be overcome.
A clear strategy, choosing the right migration method (greenfield, brownfield, or hybrid), and close collaboration between IT and business departments are crucial for a successful transformation.
Common challenges in an S/4HANA transition

- High workload for employees in specialist departments and IT, resulting in a lack of resources for the transition project
- Decision for a transition strategy under uncertainty
- Time pressure due to expiring SAP maintenance contracts, mapping of new processes in the old system, customer requirements
- Pressure to innovate
