SAP NetWeaver and SAP S/4HANA ABAP are both platforms for SAP application development, but they have significant differences in architecture, capabilities, and purpose. Here’s a detailed comparison:

1. Definition & Purpose

  • SAP NetWeaver: A technology platform that provides the foundation for SAP ERP and other SAP applications. It supports traditional ABAP development and Java-based applications.
  • SAP S/4HANA ABAP: The modern ABAP development environment optimized for SAP S/4HANA. It leverages HANA’s in-memory capabilities and introduces new development models.

2. Database Dependency

  • SAP NetWeaver: Works with multiple databases, including Oracle, MS SQL, and IBM DB2.
  • SAP S/4HANA ABAP: Exclusively designed for SAP HANA, ensuring better performance through in-memory computing.

3. Performance & Optimization

  • SAP NetWeaver: Uses conventional database access methods, often leading to slower performance due to disk-based processing.
  • SAP S/4HANA ABAP: Uses Code-to-Data principles, CDS Views, and AMDPs to push processing to the HANA database, significantly improving speed.

4. Programming Paradigm

  • SAP NetWeaver: Supports classic ABAP with Open SQL and procedural programming.
  • SAP S/4HANA ABAP: Encourages modern ABAP development using CDS (Core Data Services), AMDP (ABAP Managed Database Procedures), and RAP (RESTful Application Programming Model).

5. User Interface

  • SAP NetWeaver: Mostly supports SAP GUI and Web Dynpro applications.
  • SAP S/4HANA ABAP: Primarily uses SAP Fiori UI with OData services for a modern web-based experience.

6. Integration Capabilities

  • SAP NetWeaver: Includes integration tools like SAP PI/PO and supports SOA-based integration.
  • SAP S/4HANA ABAP: Uses SAP Gateway for OData-based integrations and aligns with SAP BTP (Business Technology Platform) for cloud-based extensibility.

7. Future Scope

  • SAP NetWeaver: Considered legacy but still in use for older SAP ERP versions.
  • SAP S/4HANA ABAP: The future of SAP development, aligned with SAP’s cloud-first strategy.

Conclusion

SAP NetWeaver is a traditional application platform that supports legacy ERP systems, while SAP S/4HANA ABAP is a modernized, performance-optimized development environment designed for HANA. If you are looking to upskill, focusing on SAP S/4HANA ABAP will be more beneficial for future SAP careers.
