SAP ABAP: 1. ABAP Development Tools (ADT) in Eclipse: • Modern IDE: ADT in Eclipse replaces the traditional SAP GUI-based ABAP Workbench, providing a modern and efficient development environment. • Enhanced Productivity: Features like code completion, syntax highlighting, and integrated testing tools improve developer productivity. 2. ABAP Core Data Services (CDS): • Data Modeling: CDS views enable data modeling directly on the database level, allowing for powerful, database-optimized queries that can be reused in various applications. • Annotations: CDS supports annotations for enriching the data model with metadata, which can be leveraged for UI generation, authorization checks, and more. 3. ABAP Managed Database Procedures (AMDP): • Optimized Performance: AMDP allows developers to write database-specific code (e.g., in SQLScript for HANA) within ABAP, optimizing performance for complex calculations and transformations. • Seamless Integration: AMDP integrates seamlessly with ABAP, enabling the use of powerful HANA database capabilities while maintaining the ABAP environment. 4. ABAP Restful Application Programming Model (RAP): • Modern Development Paradigm: RAP supports the development of cloud-ready, OData-based applications, focusing on transactional and analytical use cases. • End-to-End Development: RAP offers an end-to-end development approach, including data modeling, business logic implementation, and service provisioning. 5. ABAP on Cloud: • Stepping into the Cloud: With S/4HANA, ABAP is also available on the SAP Cloud Platform, enabling developers to build cloud-native applications using their existing ABAP skills. • Extensions: Developers can create side-by-side extensions using ABAP in the cloud, leveraging SAP’s Business Technology Platform (BTP) services. 6. Code Pushdown: • Utilizing HANA’s Power: S/4HANA promotes the concept of “code pushdown,” where calculations and processing are pushed down to the HANA database layer using SQL, CDS, or AMDP, reducing data transfer and improving performance. 7. Simplification of Data Models: • S/4HANA Simplifications: Many traditional ABAP constructs and custom developments need to be adapted to align with S/4HANA’s simplified data model, like the elimination of aggregate tables (e.g., index tables, totals tables). • Migration: ABAP developers need to adjust custom code to ensure compatibility with S/4HANA, which might involve converting database-specific logic, adapting to new APIs, and using the Simplification Database provided by SAP. 8. Fiori Integration: • UI Development: ABAP developers can now leverage SAPUI5 and Fiori elements for creating user-friendly, responsive applications that are fully integrated with the Fiori launchpad. • OData Services: ABAP developers are often required to create and maintain OData services that feed data to Fiori applications, enhancing the user experience with real-time data access.
