A free, no-signup self-assessment. Rate your SAP landscape across five Clean Core dimensions to get a maturity score and a concrete next step for each — the foundation of an upgrade-safe, AI-ready S/4HANA estate.
Some awareness, but custom code grows unchecked
Mostly classic enhancements (BAdIs, implicit enhancements)
Some standard interfaces, but mostly bespoke integration
Upgrades happen but require heavy regression and rework
Basic standards; manual testing and code review
Your Clean Core maturity
2.0 / 5
Level 2 — Reactive
Your next step per dimension
Introduce a review gate for all new custom developments
Prefer in-app/key-user extensions over classic enhancements
Catalog SAP released APIs and prefer them for new builds
Build a repeatable regression test suite
Add automated unit tests (ABAP Unit) to critical code
Indicative only. Clean Core maturity is best validated against your actual custom-code inventory and architecture — a real assessment turns this self-score into a prioritized remediation roadmap.
Clean Core keeps the standard SAP core unmodified so upgrades stay routine, BTP extensions stay safe, and Joule and other AI capabilities can be adopted without untangling years of custom code. The biggest blocker is almost always custom-code debt — which is also the single largest cost driver in an S/4HANA migration. When you are ready to turn this score into a remediation roadmap, our legacy SAP modernization services start with a custom-code assessment.
