CDS View Entities

Guide for building semantic data models using ABAP CDS (Core Data Services) view entities in ABAP Cloud.

Workflow

1. Determine the user's goal:

   • Creating a new data model (standalone or for RAP)
   • Defining relationships between entities (associations, compositions)
   • Adding annotations for UI, semantics, or analytics
   • Implementing access controls
   • Using expressions, functions, or parameters in CDS

2. Identify the context:

   • Standalone CDS view vs. RAP BO data model
   • Root entity vs. child entity vs. projection view
   • Transactional (RAP) vs. analytical vs. read-only consumption
