The framework reduces coding complexity. It also improves development speed. Developers using SAP ABAP RAP Course Online programs can quickly understand RAP architecture and workflows. Understanding Side-by-Side Extensions on SAP BTP Side-by-side extension means building custom applications outside the main SAP system. These applications run on SAP BTP instead of the core ERP system. The core SAP system remains clean and stable. Custom applications communicate through APIs and services. Why Businesses Prefer Side-by-Side Extensions Easier Upgrades Custom code stays outside the core system. SAP upgrades become smoother. Better Scalability Applications on SAP BTP can scale easily. Businesses can handle growing workloads efficiently. Faster Innovation Teams can build new features without affecting the main ERP system. Improved Security SAP BTP provides enterprise-level security and governance. How ABAP RAP Supports SAP BTP Extensions ABAP RAP is designed for cloud-native application development. It provides all the tools needed for side-by-side extensions. RAP Uses Service-Oriented Architecture RAP creates business services using OData APIs. These services connect SAP S/4HANA with external applications on SAP BTP. Developers can securely access business data from cloud applications. RAP Supports Clean Core Strategy SAP recommends keeping the ERP core clean. RAP helps developers avoid direct modifications in SAP S/4HANA. Instead, custom logic runs independently on SAP BTP. This approach improves long-term system stability. RAP Simplifies UI Development RAP automatically generates SAP Fiori-based interfaces. Developers spend less time building front-end applications. This improves productivity significantly. RAP Supports Reusable Business Objects Business objects are reusable application components. Developers can create: • Sales applications • Employee portals • Vendor management tools • Inventory systems These applications can reuse the same RAP business models. Key Components Used in RAP Development Understanding RAP components is important for beginners. CDS Views Core Data Services define business data models. They improve database performance and readability. Business Objects Business objects represent real business entities. Examples include: • Customers • Orders • Products Behavior Definitions Behavior definitions manage application logic. They define: • Create operations • Update operations • Delete operations • Validation rules Service Definitions These expose business objects as APIs. Applications on SAP BTP can consume these services. Service Bindings Service bindings connect RAP services with protocols like OData. Step-by-Step Process of Building Side-by-Side Extensions Here is a simple process developers follow. Step 1: Create CDS Data Models Developers first create CDS views for business data. These models define database relationships. Step 2: Build Business Objects Next, developers create RAP business objects. These objects handle application behavior. Step 3: Define Application Logic Business rules and validations are added. This includes approval workflows and calculations. Step 4: Expose OData Services The RAP application exposes APIs using service definitions. These APIs allow SAP BTP applications to access data. Step 5: Deploy on SAP BTP Applications are deployed to SAP Business Technology Platform. Users can access them through SAP Fiori apps. Step 6: Integrate with SAP S/4HANA Secure communication connects SAP BTP with SAP systems. This creates a complete side-by-side extension environment. Real-World Use Cases Many industries use RAP for cloud extensions. Employee Self-Service Applications Companies build leave management and reimbursement apps on SAP BTP. Employees access services without affecting the core ERP system. Supplier Collaboration Portals Suppliers can update delivery information using RAP-based portals.
