In an SAP ABAP on HANA course, you’ll focus on learning how to use ABAP (Advanced Business Application Programming) in the context of the HANA (High-Performance Analytic Appliance) database, which is SAP’s in-memory, column-oriented, relational database management system. HANA enables faster data processing, and ABAP for HANA focuses on optimizing your code to fully utilize HANA’s capabilities. Here’s an outline of what you'll typically cover:

1. Introduction to SAP HANA and ABAP on HANA

• Overview of HANA architecture, including in-memory and column-store concepts.
• Understanding HANA's impact on ABAP development and the benefits of HANA-specific optimization.
• Basic principles of in-memory data processing and how HANA’s design influences performance.

2. ABAP Development Tools (ADT) for HANA

• How to set up and use ABAP Development Tools (ADT) in Eclipse.
• Navigating the Eclipse-based ABAP workbench, creating projects, and managing versions.
• Using ADT for new HANA-specific ABAP features like Core Data Services (CDS) and ABAP Managed Database Procedures (AMDP).

3. Optimizing ABAP for HANA

• Performance tuning techniques for HANA, focusing on speeding up data retrieval and minimizing bottlenecks.
• Introduction to code-to-data paradigm, which moves data-intensive logic from the application server to the HANA database.
• Leveraging native HANA features, like aggregate functions and joins, to reduce the load on the application server.

4. Core Data Services (CDS)

• Understanding CDS and its role in simplifying and optimizing database access.
• Creating and working with CDS views for better performance and simplified data modeling.
• Using CDS annotations, associations, and access control to manage data securely and efficiently.

5. ABAP Managed Database Procedures (AMDP)

• Introduction to AMDP and their use in processing logic in the HANA database.
• Creating and managing AMDP classes and methods.
• Writing SQLScript, HANA's procedural SQL language, to define complex calculations.

6. Open SQL Enhancements

• How HANA extends Open SQL to optimize performance in HANA-based environments.
• New additions like filtering, grouping, and SQL expressions.
• Implementing advanced SQL functionalities in ABAP programs to enhance performance.

7. Code Pushdown Techniques

• Understanding the “code pushdown” concept, which transfers calculations to the database layer.
• Techniques for pushing data-intensive logic to HANA, reducing data transferred to the application server.
• Using SQLScript, CDS views, and AMDP to handle complex data processing within HANA.

8. Debugging and Analyzing Performance

• Using the ABAP Profiler, SQL Trace, and Performance Trace tools to analyze and debug ABAP programs on HANA.
• Analyzing runtime and identifying areas where performance improvements can be made.
• Optimizing code to minimize the resource usage and runtime on HANA.

9. New Data Types and ABAP Syntax in HANA

• Learning about new data types in HANA and how ABAP can handle large data volumes efficiently.
• Adapting code to leverage new ABAP syntax and data types for HANA compatibility.

10. Best Practices for ABAP on HANA

• Following SAP’s recommended best practices for developing efficient, scalable applications on HANA.
• Writing HANA-optimized code that balances performance and maintainability.

Optional Advanced Topics

Some courses may also cover additional advanced areas:

• SAP HANA XS Advanced (XS Engine) for building applications directly on HANA.
• HANA Live for real-time operational reporting.
• Leveraging Fiori for creating user-friendly interfaces on HANA-based applications.

An ABAP on HANA course is typically hands-on, so you’ll work through examples and real-world scenarios to apply these concepts directly. By the end, you should have a strong understanding of how to write efficient, optimized ABAP code tailored to HANA’s strengths and unique capabilities.
