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:

# 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

For operations: See references/operations.md
