SAP Migrations Drive 'Clean Core' Strategy
Enterprise migrations from SAP ECC to S/4HANA are accelerating, particularly in India's logistics sector, driven by the need for more resilient supply chains. The complexity of these projects has led to the promotion of a 'clean core' strategy, which emphasizes reducing custom code and standardizing data interfaces. This approach is intended to ensure scalability and maintainability, especially for companies adopting hybrid cloud deployments.
- Mainstream support for SAP's core ERP Central Component (ECC) will end on December 31, 2027, compelling businesses to migrate to S/4HANA to avoid increased costs and compliance risks. While extended maintenance is available until 2030, it comes at a premium and offers limited support. - The 'clean core' principle advocates for minimizing modifications to the standard S/4HANA code, instead using the SAP Business Technology Platform (BTP) for extensions and customizations. This approach is designed to simplify future upgrades, reduce total cost of ownership (TCO), and enhance system stability. - A significant portion of SAP customers, estimated to be over 60% globally, have not yet migrated from ECC to S/4HANA, with Indian companies in sectors like manufacturing and logistics being heavily represented in this group. As of the second quarter of 2024, only about 37% of ECC customers had licensed S/4HANA. - For supply chain operations, S/4HANA offers significant advantages over ECC by enabling real-time data processing and analytics. This allows for improved demand forecasting, better inventory management, and increased visibility across the entire supply chain. - The migration journey itself can be complex and lengthy, with standard projects taking approximately 18 months to complete. Companies must choose between a complete reimplementation (Greenfield), a technical upgrade (Brownfield), or a hybrid approach. - To aid in the transition, SAP and its partners offer a range of tools. The SAP S/4HANA Migration Cockpit provides a guided process for data migration, while custom code analysis tools help identify unused or obsolete code that can be eliminated. - The "RISE with SAP" offering has become a popular pathway for cloud adoption, bundling the S/4HANA software with cloud infrastructure and technical services into a single contract. Recent reports show a surge in S/4HANA Private Cloud usage, which increased to 33% from 11% in the previous year. - Major IT service providers like Tata Consultancy Services, Infosys, and Wipro are key implementation partners for S/4HANA migrations in India, offering services from initial assessment to post-migration support.
