Course Overview

Step into the high-value world of enterprise ERP engineering with this specialized masterclass designed for the modern SAP S/4HANA Cloud era. As global Fortune 500 corporations transition away from legacy ECC systems, this program trains you in SAP's official 'Clean Core' paradigm. You will bypass outdated procedural scripting and master the bleeding-edge modern ABAP stack: developing in Eclipse ABAP Development Tools (ADT), modeling virtual database logic with Core Data Services (CDS Views), and engineering enterprise-grade transactional applications using the ABAP RESTful Application Programming Model (RAP). Furthermore, you will explore cloud integration on the SAP Business Technology Platform (BTP), mastering event-driven messaging and OData service provisioning for modern SAP Fiori interfaces.

Course Curriculum

1. Enterprise SAP S/4HANA Architecture & 'Clean Core' Principles

  • Evolution of SAP ERP: From legacy R/3 and ECC 6.0 to SAP S/4HANA Cloud (Public vs Private Cloud models)
  • The 'Clean Core' imperative: Eliminating spaghetti 'Z-code' modifications and establishing upgrade-stable ERP architectures
  • In-App Extensibility vs Side-by-Side Extensibility: Deciding when to extend on-stack vs on SAP Business Technology Platform (BTP)
  • SAP HANA in-memory architecture: Row vs columnar storage, memory engines, and the Code-to-Data execution paradigm

2. Modern ABAP & Eclipse ABAP Development Tools (ADT)

  • ABAP Language Versions: Standard ABAP vs ABAP for Cloud Development (restricted language scope and released APIs)
  • Modern development environment: Transitioning from legacy SAP GUI (SE38/SE80) to Eclipse ADT with abapGit version control
  • Advanced Object-Oriented ABAP: Interfaces, abstract classes, functional methods, and modern constructor operators (VALUE, CORRESPONDING, FILTER)
  • Modern ABAP SQL: Path expressions, windowing functions, strict mode syntax checks, and dynamic internal table processing

3. Core Data Services (CDS Views) & Virtual Data Models (VDM)

  • CDS View Entities: Defining semantic database projections directly within the SAP HANA database layer
  • CDS Associations vs Joins: On-demand lazy-loading joins and cardinalities in complex enterprise data models
  • CDS Annotations: Leveraging UI annotations (@UI.lineItem, @UI.identification), Search annotations, and Semantics
  • Metadata Extensions (MDE): Decoupling UI rendering directives from core database view definitions
  • Data Control Language (DCL): Implementing row-level and authorization-object security access controls on CDS entities

4. ABAP RESTful Application Programming Model (RAP) - Architecture & Modeling

  • The 3-tier RAP architecture: Data Modeling & Business Logic, Behavior Definition, and Business Service Provisioning
  • Managed vs Unmanaged RAP scenarios: Understanding when to leverage SAP's standard framework vs custom legacy APIs
  • Behavior Definitions (BDEF): Defining standard CRUD operations, draft handling capabilities, and lock masters
  • Service Definitions & Service Bindings: Exposing business objects as enterprise OData v2 and OData v4 web services

5. ABAP RAP Behavior Implementation & Transactional Logic

  • Behavior Implementation Pools (BIL): Writing business logic inside Local Types classes (LCL_HANDLER and LCL_SAVER)
  • Determinations & Validations: Implementing automated field calculations and data integrity checks on modify
  • Custom Business Actions & Factory Actions: Creating state-transition actions (e.g., 'Approve Purchase Order', 'Issue Invoice')
  • Dynamic Feature Control: Managing field properties (read-only, mandatory, hidden) dynamically based on instance status
  • Draft Handling: Managing transient database draft tables and automated background auto-save states

6. SAP Business Technology Platform (BTP) & Fiori Integration

  • SAP BTP overview: Global accounts, subaccounts, Cloud Foundry, and BTP ABAP Environment (Steampunk)
  • Side-by-Side Extensibility: Decoupling custom enterprise applications from the S/4HANA core via REST APIs and Event Mesh
  • SAP Fiori Elements: Generating responsive enterprise web applications directly from annotated RAP OData services
  • ABAP Test Cockpit (ATC) & Custom Code Migration: Analyzing and refactoring legacy ABAP code for S/4HANA Cloud readiness
  • Capstone Project: Enterprise Supplier & Procurement Portal built with ABAP RAP, Draft Handling, CDS Views, and SAP Fiori Elements
