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

ABAP Cloud Development

ABAP Cloud uses four foundational technologies:

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

For ABAP details: See

references/abap-cloud.md

Development Workflow

Phase 1: Explore and Discover

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

Phase 2: Design

User Experience Design
- Follow SAP Fiori Design Guidelines
- Implement accessibility (WCAG 2.2)
- Use design thinking methodology
Technology Design
- Apply Domain-Driven Design for complex applications (30+ use cases)
- Define module boundaries and communication patterns
- Plan microservices architecture if needed
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:

bash

# 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:

bash

# Build MTA archive
mbt build

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

Kyma Deployment:

bash

# 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

For operations: See

references/operations.md
