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.
