What is Clean Core?

SAP Clean Core is the principle of keeping the SAP standard (the "core") untouched — using only approved extension technologies, standard integration APIs, and industry process standards. A clean core programme can upgrade from S/4HANA On-Premise to S/4HANA Cloud (RISE) with minimal rework. A "dirty" core with classic modifications becomes extremely costly to migrate.

Ontology — why your score moved

Every Clean Core criterion is a node in the SAP extensibility ontology with a tiered remediation path (Tier 1 = SAP-recommended target state, Tier 4 = legacy / dirty-core pattern). The composite score is the weighted roll-up of where each criterion currently sits on its tier ladder.

Extension Compliance · SAP Core Modifications
Tier path: Modifications → BAdI → Released Enhancement Spot → No-mod (key-user extensibility)
Tier 1 = no mods → Tier 4 = classic mods — current score 7/10
Extension Compliance · Custom Code Location
Tier path: Z-namespace → Developer Extensibility (ABAP Cloud) → BTP side-by-side
Tier 1 = BTP side-by-side → Tier 4 = on-stack mods — current score 8/10
Extension Compliance · ABAP Development Style
Tier path: Classic ABAP → Clean ABAP OO → ABAP Cloud (Released APIs only)
Tier 1 = ABAP Cloud → Tier 4 = classic — current score 7/10
Extension Compliance · Fiori Extension Approach
Tier path: GUI → Fiori Elements → Key-User UI Adaptation → Standard Fiori
Tier 1 = standard → Tier 4 = SAP GUI — current score 9/10
Extension Compliance · Enhancement Technique
Tier path: Source mod → Implicit Enh → Explicit Section → Released BAdI
Tier 1 = Released BAdI → Tier 4 = source mod — current score 7/10
Integration Compliance · Integration Technology
Tier path: Direct DB → RFC/BAPI → Standard APIs → SAP Integration Suite
Tier 1 = Integration Suite → Tier 4 = direct DB — current score 9/10
Integration Compliance · API Type Used
Tier path: Direct table → Unreleased API → BAPI → Released OData (SAP Graph)
Tier 1 = Released OData → Tier 4 = direct table — current score 8/10
Integration Compliance · Event-Driven Architecture
Tier path: Polling → Custom events → IDoc/BAPI events → SAP Event Mesh
Tier 1 = Event Mesh → Tier 4 = no events — current score 7/10
Integration Compliance · Middleware / iPaaS
Tier path: P2P → Custom middleware → Partner iPaaS → SAP Integration Suite
Tier 1 = Integration Suite → Tier 4 = point-to-point — current score 7/10
Process Compliance · Process Adoption Level
Tier path: Heavy custom → Significant gaps → Minor gaps → 100% Best Practice
Tier 1 = Best Practice → Tier 4 = heavy custom — current score 8/10
Process Compliance · Industry Best Practices
Tier path: Fully custom → Partial adoption → BP with gaps → SAP Best Practice activated
Tier 1 = activated → Tier 4 = custom design — current score 7/10
Process Compliance · Configuration vs Customisation
Tier path: ABAP-driven → Mix → Mainly config → Configuration only
Tier 1 = config only → Tier 4 = ABAP-driven — current score 7/10
Process Compliance · Upgrade Testing Overhead
Tier path: High overhead → Medium → Low → Minimal upgrade impact
Tier 1 = minimal → Tier 4 = high — current score 7/10
Data Compliance · Custom Table Strategy
Tier path: Shadow tables → Z-tables → Extension Fields → No custom tables
Tier 1 = no custom tables → Tier 4 = shadow — current score 8/10
Data Compliance · Data Model Extensions
Tier path: Table mods → Append structures → Key-User Fields → CDS/RAP on ABAP Cloud
Tier 1 = CDS/RAP → Tier 4 = table mod — current score 8/10
Data Compliance · Master Data Governance
Tier path: None → Manual → Basic MDG → SAP MDG with workflow
Tier 1 = MDG + workflow → Tier 4 = none — current score 7/10
Data Compliance · Analytics / Reporting
Tier path: Direct extract → Custom ABAP / BW → Embedded Analytics → SAP Analytics Cloud
