ABAP Cloud / Clean Core

Guide for developing with the ABAP Cloud programming model, understanding the 3-tier extensibility model, and applying clean core principles.

Workflow

Determine the user's context:
- Understanding ABAP Cloud concepts and restrictions
- Choosing the right extensibility tier
- Wrapping unreleased APIs for use in ABAP Cloud
- Identifying released API alternatives
- Setting up clean core-compliant development
Identify the extensibility tier:
- Tier 1: Key user extensibility (no code)
- Tier 2: Developer extensibility (ABAP Cloud / ABAP for Cloud Development)
- Tier 3: Classic extensibility (standard ABAP, only on-premise/private cloud)
