Difference between SAP ECC and S/4HANA for ABAP Programmers

SAP ECC (Enterprise Central Component) is the previous generation of SAP's ERP system, while S/4HANA is the latest version that runs on the SAP HANA in-memory database. The main difference between the two lies in the underlying technology and architecture.

The impact on ABAP programming is significant. ABAP developers working with S/4HANA need to adapt to the new data model, as S/4HANA simplifies the database structure and uses a more streamlined data model compared to ECC. Additionally, S/4HANA offers new programming capabilities and performance improvements due to its in-memory computing capabilities.

To sum up, the transition from SAP ECC to S/4HANA requires ABAP programmers to update their skills, learn the new data model, and take advantage of the enhanced programming features to fully leverage the benefits of S/4HANA.
