SAP ECC is SAP’s legacy ERP platform used by enterprises to manage core business processes such as finance, logistics, sales, production, and human resources. It provides modular, integrated functionality that supports end-to-end operations in a centralized system.
SAP ECC runs on traditional databases and has been widely used for decades. SAP S/4HANA is the next-generation ERP that runs on the HANA in-memory database, offering real-time data processing, modern user interfaces (SAP Fiori), and simplified data structures. ECC is being phased out, with SAP ending mainstream support in 2027.
SAP will provide mainstream support for ECC until 2027, with optional extended maintenance available until 2030. Businesses running ECC should begin planning their migration strategy to SAP S/4HANA to ensure long-term system support and access to innovations.
Many enterprises continue to use SAP ECC because it is stable, familiar, and highly customized to their operations. ECC remains suitable for companies that are not yet ready for a full migration to S/4HANA due to cost, complexity, or current IT priorities.
