SAP architects, ERP modernization leads, and IT governance professionals evaluating SAP system extensibility and customization maturity
Determine the current SAP clean core maturity level to guide modernization, extensibility strategy, and technical debt reduction efforts
Decision context
SAP clean core maturity assessment is a structured evaluation designed to measure how closely an SAP system aligns with clean core principles, minimizing custom code and maximizing standard SAP extensibility usage. This assessment helps organizations understand the extent of customizations, their impact on upgradeability, and the technical debt embedded in their SAP landscape.
Adranum’s assessment framework ingests diverse evidence including ABAP custom code, DDIC objects, SAP readiness checks, ATC results, and process-event data to build a comprehensive maturity profile. It identifies unsupported or risky customizations, maps dependencies, and highlights areas where modernization or remediation is needed to achieve a cleaner core.
This maturity assessment is critical for organizations planning SAP S/4HANA transformations, cloud migrations, or continuous improvement initiatives. It informs decisions on whether to keep, remediate, replace, or retire custom developments, ensuring extensibility aligns with SAP’s recommended best practices and reduces long-term maintenance burdens.

Understanding SAP Clean Core and Extensibility Levels
SAP clean core refers to an SAP system state where customizations and extensions are implemented using SAP’s recommended extensibility frameworks rather than invasive modifications. This approach preserves the upgrade path and reduces complexity.
Extensibility levels range from unmanaged custom code and modifications to fully supported in-app and side-by-side extensibility models. The maturity assessment maps your system’s current state against these levels to identify gaps and risks.
By categorizing custom developments according to extensibility levels, the assessment provides actionable insights on modernization priorities and compliance with SAP’s clean core guidelines.
- Defines clean core principles and extensibility categories
- Differentiates between modification, in-app, and side-by-side extensibility
- Highlights upgrade and supportability implications
Comprehensive Evidence Collection and Analysis
The assessment ingests multiple evidence sources including SAP Readiness Check data, ABAP Test Cockpit (ATC) results, abapGit repositories, and DDIC metadata to form a holistic view of custom code and data objects.
It analyzes code quality, usage of unsupported APIs, and dependency graphs between custom and standard SAP objects to identify potential upgrade blockers.
Process-event and requirement evidence further contextualize customizations within business processes, revealing bottlenecks and variant usage that affect extensibility decisions.
- Aggregates SAP readiness and ATC scan results
- Maps ABAP and DDIC dependencies
- Includes process and requirement traceability for business context
Maturity Level Scoring and Reporting
Adranum generates a maturity scorecard that quantifies the degree of clean core alignment across multiple dimensions such as code compliance, extensibility framework usage, and unsupported modifications.
Reports detail unsupported inputs, coverage gaps, and remediation recommendations, enabling targeted modernization planning.
The maturity levels are presented with clear visualizations and drill-down capabilities to support stakeholder reviews and governance.
- Quantitative scoring across extensibility dimensions
- Detailed unsupported code and object listings
- Actionable remediation and modernization guidance
Integration with SAP Modernization Lifecycle
The maturity assessment is designed as an integral part of the SAP modernization lifecycle, feeding into decision workflows for keep, remediate, replace, or retire custom developments.
It supports creation of reviewable code and data proposals, implementation packages, and impacted test sets aligned with maturity findings.
Human approvals and cutover coordination are managed to ensure controlled remediation and transition to a cleaner core state.
- Supports decision gates for custom code disposition
- Generates implementation and test packages
- Coordinates approvals and cutover activities
Limitations and Considerations
The assessment does not replace SAP licensing or Basis administration responsibilities and should be complemented by specialist testing tools where needed.
Generated remediation proposals require customer-controlled compilation and runtime validation before production deployment.
The tool does not guarantee SAP certification or compliance but provides evidence-based guidance to improve clean core maturity.
Missing or incomplete input data may limit assessment completeness and should be addressed prior to evaluation.
- Not a substitute for SAP licensing or Basis governance
- Proposals require customer validation and testing
- No official SAP certification or guarantee
- Dependent on completeness of input evidence
What the workflow must cover
- Multi-source Evidence Ingestion. Adranum ingests SAP readiness, ATC, ABAP, DDIC, abapGit, process-event, and requirement evidence to build a comprehensive assessment dataset.
- Dependency Mapping and Impact Analysis. The tool maps observed and inferred dependencies between custom and standard SAP objects to identify upgrade risks and remediation targets.
- Extensibility Level Classification. Custom developments are categorized according to SAP’s extensibility levels, enabling precise maturity scoring and modernization guidance.
- Automated Maturity Scoring and Reporting. Generates quantitative scores and detailed reports highlighting unsupported inputs, coverage gaps, and remediation recommendations.
- Decision Workflow Support. Facilitates keep/remediate/replace/retire decisions with reviewable proposals, implementation packages, and test impact analysis.
- Governed Cutover and Recovery Coordination. Coordinates cutover, reconciliation, continuity, and exact-state recovery activities aligned with maturity improvement efforts.
Implementation workflow
Start with a bounded customer scenario and explicit acceptance criteria. Preserve native SAP permissions and accountable review while the software creates a repeatable evidence chain.
- Collect SAP readiness check and ATC scan results from the target system.
- Aggregate ABAP custom code, DDIC objects, and abapGit repositories for analysis.
- Map dependencies and classify custom developments against SAP extensibility levels.
- Calculate maturity scores and generate detailed reports with unsupported input listings.
- Review reports with SAP architects and business stakeholders to identify remediation priorities.
- Create remediation proposals and implementation packages aligned with maturity findings.
- Coordinate approvals, cutover planning, and post-implementation reconciliation to finalize maturity improvements.
Evidence to require
A transformation claim should resolve to observable artifacts, decisions, and execution receipts. Ask for the following evidence in a representative evaluation:
- SAP Readiness Check export files
- ABAP Test Cockpit (ATC) scan results
- ABAP custom code repositories
- DDIC metadata extracts
- abapGit source control snapshots
- Process-event logs and variant usage data
- Business requirement traceability documents
- Dependency graphs between custom and standard objects
- Remediation proposal documents
- Implementation package manifests
Boundaries and non-claims
Adranum separates analysis, proposal, human review, package creation, customer-local validation, and production execution. A later state never rewrites the evidence that supported an earlier decision.
- Does not replace SAP licensing or Basis administration roles
- Generated code proposals require customer compilation and runtime validation
- Missing or incomplete input data reduces assessment accuracy
- No official SAP certification or guarantee of compliance
