When to Use This Skill

Use when:

• Building new applications on SAP BTP (Cloud Foundry or Kyma runtime)
• Developing with SAP Cloud Application Programming Model (CAP)
• Building ABAP Cloud applications in SAP BTP ABAP Environment
• Deploying SAP Fiori or SAPUI5 user interfaces
• Connecting applications to SAP S/4HANA, SuccessFactors, or on-premise systems
• Building multitenant SaaS applications
• Implementing side-by-side extensions for SAP solutions
• Building AI-powered extensions (LLM analysis, document processing, intelligent automation)
• Setting up CI/CD pipelines for SAP BTP
• Implementing observability with SAP Cloud ALM or SAP Cloud Logging
• Using SAP HANA Cloud for data persistence

Decision Matrix

CAP Application Development

CAP provides three operational profiles:

• Development: Mock services, minimal setup, SQLite/H2 for local testing
• Hybrid: Local app connected to cloud services
• Production: Full cloud deployment with SAP HANA Cloud

Key capabilities:

• Domain-driven design with CDS (Core Data Services)
• Built-in multitenancy support
• Automatic OData/REST service generation
• Platform-agnostic design (no vendor lock-in)

For CAP details: See references/cap-development.md

AI-Powered Extensions with CAP

Build intelligent side-by-side extensions by combining CAP with SAP AI Core:

1. Bind AI Core to your CAP app via MTA (service: aicore, plan: extended)
2. Use SAP Cloud SDK for AI (@sap-ai-sdk/orchestration) in CAP event handlers — never raw HTTP calls
3. Process asynchronously: LLM calls can take 30-60 seconds. Return 202 Accepted and use cds.spawn for background processing to avoid BTP load balancer timeouts
4. Store vectors: Use HANA Cloud Vector(1536) type in CDS entities for RAG scenarios
5. Externalize prompts: Store in JSON files or CDS entities for updates without redeployment
6. Allocate memory: At least 512MB for Node.js containers with AI SDK

For complete code examples, see sap-cap-capire skill (AI Integration section) and sap-cloud-sdk-ai skill (CAP Integration subsection).

ABAP Cloud Development

ABAP Cloud uses four foundational technologies:

1. Core Data Services (CDS) - Data modeling and analytics
2. ABAP RESTful Application Programming Model (RAP) - Service-oriented development
3. Restricted ABAP Language - Cloud-safe API access
4. Released Public APIs - Upgrade-stable extensions

For ABAP details: See references/abap-cloud.md

Development Workflow

Phase 1: Explore and Discover

1. Identify business problem - Conduct stakeholder interviews
2. Understand user needs - Visit customers, observe workflows
3. Define security requirements - Threat modeling, compliance planning (GDPR, HIPAA)
4. Establish governance - Set up organizational structure

Phase 2: Design

1. User Experience Design

   • Follow SAP Fiori Design Guidelines
   • Implement accessibility (WCAG 2.2)
   • Use design thinking methodology

2. Technology Design

   • Apply Domain-Driven Design for complex applications (30+ use cases)
   • Define module boundaries and communication patterns
   • Plan microservices architecture if needed

3. Security in Design

   • Secure user interfaces with SAP Fiori authentication
   • Implement RBAC/ABAC using OAuth/OpenID Connect
   • Validate CDS models for data protection

For design patterns: See references/design-patterns.md

Phase 3: Develop

CAP Development:

# Initialize CAP project
cds init my-project
cd my-project

# Add SAP HANA support
cds add hana

# Add authentication
cds add xsuaa

# Run locally
cds watch

Key development tools:

• SAP Business Application Studio (primary IDE)
• SAP Cloud SDK (OData/OpenAPI clients)
• MTA Build Tool (packaging)

Coding standards:

• Follow SAPUI5 Guidelines and SAP Fiori Design Guidelines
• Establish naming conventions
• Implement parameterized queries (prevent SQL injection)
• Use CDS constraints for input validation

For tools catalog: See references/tools.md

Phase 4: Deploy

Cloud Foundry Deployment:

# Build MTA archive
mbt build

# Deploy to Cloud Foundry
cf deploy mta_archives/my-project_1.0.0.mtar

Kyma Deployment:

# Use Helm charts or Terraform
terraform init
terraform apply

ABAP Deployment:

• Use Manage Software Components app (gCTS)
• Transport via Landscape Portal
• Partner options: Multitenant SaaS or Add-on Product

For deployment details: See references/deployment.md

Phase 5: Run and Scale

Monitoring:

• SAP Cloud ALM (central observability)
• SAP Cloud Logging (detailed logs, metrics, traces)
• ABAP Technical Monitoring Cockpit

Scaling:

• Cloud Foundry: Automatic instance distribution across AZs
• Kyma: Kubernetes-native scaling
• ABAP: Elastic scaling with ACUs (0.5 ACU increments)

Cost optimization:

• System hibernation (ABAP) - reduce to <5% operational cost
• SAP HANA Cloud Native Storage Extension
• Elastic Compute Nodes for peak workloads
