SAP Certified Associate - Back-End Developer - ABAP Cloud

Master fundamental ABAP programming concepts including data types, ABAP Dictionary objects, internal tables (standard, sorted, hashed), modularization techniques, exception handling with TRY-CATCH blocks, field symbols, constructors, modern expression-based ABAP syntax (VALUE, CORRESPONDING, REDUCE, inline declarations), and local class implementation. Includes working with strings, dates, data conversions, debugging techniques, ABAP Unit testing framework, and ABAP runtime behavior.

Design and implement CDS view entities with annotations, associations, and joins for data modeling. Create and configure associations with proper cardinality and ON conditions, use path expressions for data access, implement metadata extensions with ANNOTATE VIEW, apply framework-specific annotations (#CORE, #LOCALIZATION, #INDUSTRY, #PARTNER, #CUSTOMER), aggregations, calculations, and virtual elements. Includes integration with OData services, Fiori apps, authorization and access control, and CDS view performance optimization.

Develop transactional applications using RAP framework by defining business objects with behavior definitions, implementing Entity Manipulation Language (EML) for CRUD operations, creating draft-enabled services, building OData UI services, and implementing managed, unmanaged, or partially managed data access. Configure actions, validations, determinations, dynamic feature control, authority checks, business events. Work with composite business objects, hierarchical node structures, service binding, and SAP Fiori Elements integration.

Implement extensibility solutions following clean core principles using key-user extensibility (custom fields, CDS views, business objects) and developer extensibility (ABAP classes, interfaces, CDS entities). Apply restricted ABAP syntax with whitelisted released APIs only (C_* for classes, R_* for interfaces). Verify release status of BAPIs, tables, classes, and interfaces before use using Cloud API Statistics, Released ABAP Artifact Explorer, or ADT property filter (USE_IN_CLOUD_DEVELOPMENT). Avoid prohibited operations like direct database modifications and dynamic programming. Side-by-side extensions on SAP BTP, in-app extensions, released SAP APIs and extension points for S/4HANA Cloud.

Optimize database operations using Open SQL with GROUP BY, aggregate functions (MAX, MIN, AVG, SUM), CASE expressions, and inline data declarations. Implement code pushdown with ABAP Managed Database Procedures (AMDP), Native SQL with ADBC for HANA-specific optimizations. Apply SQL Monitor, ABAP Test Cockpit (ATC), and Code Inspector for performance analysis.

Apply object-oriented ABAP programming: global and local classes with visibility (PUBLIC, PROTECTED, PRIVATE), interfaces for polymorphism, inheritance with superclass and subclass, abstract classes and methods, method redefinition. SOLID principles, design patterns in ABAP Cloud, events and event handling, encapsulation and access modifiers.
