Major Differences Between SAP ECC and SAP S/4 HANA


Major Differences Between SAP ECC and SAP S/4 HANA

SAP ERP Central Component, commonly referred to as SAP ECC, is fast approaching its end-of-support phase. Over the next five years, SAP will actively promote and facilitate the migration of its ECC customers to their cutting-edge fourth-generation ERP solution, SAP S/4HANA. This transition marks a pivotal step forward in the world of enterprise resource planning, as SAP S/4HANA offers a host of advanced features and capabilities designed to empower businesses with real-time insights, improved agility, and enhanced efficiency. To stay competitive and future-ready, organizations are encouraged to embark on the journey to migrate to SAP S/4HANA, ensuring they can harness the full potential of this modern ERP platform for sustainable growth and innovation.

To gain insight into the business advantages that SAP’s ERP customer base can derive from S/4HANA, let’s begin by examining some of the primary distinctions between SAP ECC and S/4HANA. This blog will help you understand the differences and can be your guide for ECC to S/4HANA.

Difference Between SAP ECC and SAP S/4 HANA

SAP ECC Modular Structure

SAP ECC encompasses a range of distinct modules that organizations can employ to optimize processes across various business domains such as Finance, Logistics, HR, Product Planning, and Customer Service.

This modular structure permits organizations to select and implement specific modules according to their requirements. However, this adaptability introduces intricacies into the system. Each module necessitates individual configuration, and any alterations in one module can potentially impact others. Consequently, organizations must meticulously evaluate the implications of upgrades or customizations on each individual module.

In contrast, S/4HANA has introduced numerous simplifications, both in the IT framework and data architecture. Serving as an intelligent ERP system, it minimizes complexity, enabling organizations to enhance the speed and efficiency of their operations. S/4HANA’s product strategy acknowledges the imperative for customers venturing into new markets or adopting fresh business processes to swiftly integrate new functionalities. This agility in adding extensions is facilitated by S/4HANA’s Cloud Platform. Furthermore, S/4HANA’s recent and forthcoming roadmap encompasses the inclusion of all ECC functions, including APO, CRM, SRM, EWM, and TM.

SAP S/4HANA In-Memory Computing Capabilities

While SAP ECC has the flexibility to operate on third-party databases like Oracle DB or IBM DB2, S/4HANA exclusively relies on the SAP HANA database. The SAP HANA database boasts formidable in-memory capabilities that form the bedrock of S/4HANA’s ERP functionality. This unique feature allows data to reside in the primary RAM, enabling the system to retrieve data at a significantly faster pace compared to other database types, which necessitate fetching data from the hard disk.

Furthermore, the database employs a column-based structure, ensuring that only relevant columns are accessed, resulting in expeditious retrieval of the necessary data. This design permits parallel processing of diverse columns and also achieves more efficient data compression.

Notably, the HANA database facilitates real-time reporting and predictive analysis by enabling Online Transactional Processing (OLTP) and Online Analytical Processing (OLAP) to occur within the same system. Lastly, it dispenses with the need for aggregates, indexes, or historical tables. Instead, aggregates are generated dynamically within the HANA database based on line item tables.

SAP S/4 HANA Provides a Single Source of Truth in the Universal Journal

The Universal Journal, also known as ACDOCA, stands as a consolidated single-entry table merging the data frameworks of FI, AA, CO, CO-PA, and ML. This streamlined approach to data management simplifies operations, as information is directed into a solitary table rather than being distributed across multiple tables.

Additionally, SAP S/4HANA introduces MATDOC, a fresh line item designed for inventory management. This innovation leads to a reduction of approximately 26 tables when compared to the table structure in SAP ECC.

SAP S/4HANA brings about simplifications in various dimensions, notably streamlining table and data structures to enhance efficiency. Additionally, outdated or non-essential functionalities have been eliminated and replaced with improved features. In line with S/4HANA’s strategy to reduce complexity, the S/4HANA Cloud edition minimizes core development and allows non-core customizations through external applications, ensuring a seamless adoption of new functionality.

Standard integrations are readily available to seamlessly incorporate other cloud solutions such as SAP SuccessFactors Employee Central, SAP Ariba, IBP, C4C, and Commerce, simplifying the overall IT landscape. Furthermore, the HANA Cloud Platform (HCP) offers the flexibility to enhance S/4HANA’s capabilities through extensions and the development of new applications. These guided customizations encompass integration, UI/UX, IoT, Analytics, and database-level services, presenting a simplified yet effective technological blend that greatly benefits SAP S/4HANA customers.

Front-End Innovation Utilizing Fiori Apps

SAP S/4HANA adopts SAP Fiori as its front-end interface, offering robust personalization capabilities to enhance the user experience significantly. One noteworthy feature is the Fiori Lighthouse scenarios, which present users with real-time reports on an intuitive overview screen.

Another intriguing addition is the Fiori app called Copilot, which serves as a digital assistant, also available as a mobile app. Many consider Copilot to be a transformative element within S/4HANA. It’s important to note that, given the extensive and comprehensive nature of S/4HANA, the aspects mentioned here represent only a fraction of the innovations it brings.
