SAP ABAP (Advanced Business Application Programming) is a programming language used in SAP for developing applications on the SAP platform. If you're looking to get trained in ABAP, here's a typical training roadmap:
1. Introduction to SAP and ABAP Basics
- Overview of SAP ERP: Understanding the architecture, different modules (like MM, SD, FI, etc.), and how SAP ABAP fits into the landscape.
- ABAP Dictionary (DDIC): Learning about Data Elements, Domains, Tables, Views, and Lock Objects.
- Basic ABAP Syntax: Familiarization with ABAP syntax, data types, operators, and control statements (IF, WHILE, etc.).
2. ABAP Programming
- Modularization Techniques: Subroutines, function modules, macros, and includes.
- Data Retrieval: Understanding Open SQL for interacting with SAP databases (SELECT, INSERT, UPDATE, DELETE).
- Internal Tables: Learning about dynamic and static internal tables, sorting, filtering, and manipulating data.
- ALV Reporting: Create reports using ALV (ABAP List Viewer) for effective data presentation.
3. Dialog Programming
- Module Pool Programming: Designing custom screens, handling user inputs, and navigating between screens.
- Screen Painter and Menu Painter: Learn how to create screens and menus for custom SAP applications.
- Field Validation and Error Handling: Implementing field-level validations, error handling, and message class usage.
4. Data Migration and BDC (Batch Data Communication)
- BDC Techniques: Learn about BDC Call Transaction, BDC Session, and BAPI (Business Application Programming Interface).
- LSMW: Understand the Legacy System Migration Workbench (LSMW) tool for data migration.
5. Enhancements and Modifications
- User Exits: Learn about predefined enhancement options to modify standard SAP functionality.
- BADI (Business Add-Ins) and Enhancement Framework: Learn how to enhance standard SAP functionality without modifying the original code.
- Customer Exits: Working with customer exits for extending standard SAP functionality.
6. Performance Optimization
- SQL Trace and Runtime Analysis: Learn how to optimize performance by analyzing database calls and memory usage.
- Efficient ABAP Code: Techniques to optimize ABAP code for performance (e.g., using proper loop statements, avoiding nested SELECTs, etc.).
7. Advanced Topics
- Object-Oriented ABAP (OOABAP): Introduction to object-oriented programming principles in ABAP, including classes, objects, inheritance, and polymorphism.
- ABAP on HANA: Learn the new features of ABAP specific to SAP HANA, like Code-to-Data Paradigm and ABAP Managed Database Procedures (AMDP).
8. SAP Fiori and OData Services (Optional for Full-stack Development)
- OData Services: Learn how to expose ABAP functions as OData services to integrate with SAP Fiori and external applications.
- Fiori Launchpad Integration: If you're focusing on full-stack SAP development, understanding Fiori is essential for creating user-friendly interfaces.
