SAP Carve-in for Governed ERP Change

Decision context

SAP carve-in refers to the process of integrating a newly acquired or merged SAP system into an existing SAP landscape. This operation requires precise governance over code, data, and process dependencies to avoid disruption and ensure compliance with business and technical requirements. Adranum specializes in supporting SAP carve-in by ingesting comprehensive SAP evidence and orchestrating controlled modernization workflows.

Unlike carve-out, which separates SAP components, carve-in focuses on merging SAP systems or modules into a target environment. This involves analyzing readiness, mapping dependencies, and proposing code and data changes that align with the target SAP architecture. Adranum’s evidence-driven approach helps identify unsupported inputs and coverage gaps early, reducing risk during integration.

Successful SAP carve-in demands coordination between development, testing, and operations teams. Adranum facilitates this by generating reviewable implementation packages, impacted test sets, and cutover plans. It also records approvals and supports exact-state recovery to maintain system integrity throughout the carve-in lifecycle.

Understanding SAP Carve-In Challenges

SAP carve-in projects must reconcile differences in custom code, data models, and business processes between source and target systems. Without clear visibility into dependencies and unsupported elements, integration can introduce errors or compliance issues.

Adranum addresses these challenges by ingesting authorized SAP readiness, ABAP, DDIC, and process-event evidence to build a comprehensive dependency map. This enables informed decisions on whether to keep, replace, remediate, or retire components during integration.

• Comprehensive dependency mapping across SAP components
• Identification of unsupported or missing inputs
• Proposal of code and data remediation or replacement

Governed Code and Data Proposals

Adranum generates reviewable proposals for code and data changes required to integrate SAP systems. These proposals remain under customer control until compilation and runtime validations succeed, ensuring no unverified changes reach production.

This governance model supports iterative refinement and human approvals, reducing the risk of integration errors and maintaining alignment with SAP best practices and customer policies.

• Content-addressed implementation packages
• Reviewable code and data change proposals
• Human approval recording and audit trails

Coordinated Cutover and Recovery

Cutover during SAP carve-in is a critical phase requiring precise coordination to minimize downtime and data inconsistencies. Adranum orchestrates cutover activities, reconciliation, continuity checks, and exact-state recovery to maintain system stability.

By tracking impacted tests and generating reconciliation evidence, Adranum enables traceability and auditability of the cutover process, supporting compliance and operational resilience.

• Cutover coordination and scheduling
• Reconciliation and continuity verification
• Exact-state recovery support

Integration with Customer Infrastructure

Adranum allows signed customer operators to keep raw service data, source code, and credentials within their own infrastructure. Only bounded commands, hashes, aggregate outcomes, and receipts leave the environment, preserving data sovereignty and security.

This architecture aligns with stringent compliance requirements and reduces risk associated with external data exposure during carve-in projects.

• Local retention of sensitive data and credentials
• Outbound transmission limited to bounded commands and hashes
• Compliance with customer security policies

Process Variant Observation and Improvement

Adranum captures observed process variants and bottlenecks during carve-in, enabling immutable simulations and historical improvement tracking. This insight supports continuous process optimization post-integration.

By documenting improvement history, organizations can refine their SAP carve-in methodology and reduce future integration risks.

• Observation of process variants and bottlenecks
• Immutable simulation capabilities
• Improvement history documentation

What the workflow must cover

• Dependency Mapping. Adranum ingests multiple SAP evidence types to build a detailed map of observed and inferred dependencies critical for carve-in decisions.
• Code and Data Proposal Generation. It creates reviewable proposals for code and data changes, supporting keep, replace, remediate, or retire decisions under customer control.
• Implementation Package Creation. Generates content-addressed packages that include impacted tests and compile/runtime receipts to facilitate controlled deployment.
• Cutover Orchestration. Coordinates cutover activities with reconciliation and exact-state recovery to ensure system stability during carve-in.
• Human Approval Recording. Records operator approvals and maintains audit trails to support governance and compliance requirements.
• Process Variant Analysis. Captures and analyzes process variants and bottlenecks to support simulation and continuous improvement during carve-in.

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.

1. Ingest authorized SAP readiness, ATC, ABAP, DDIC, and process-event evidence from source and target systems.
2. Analyze dependencies and unsupported inputs to identify integration gaps and risks.
3. Generate reviewable code and data change proposals aligned with carve-in objectives.
4. Record human approvals and refine proposals through iterative validation and testing.
5. Create content-addressed implementation packages including impacted tests and compile/runtime receipts.
6. Coordinate cutover activities with reconciliation, continuity checks, and exact-state recovery.
7. Monitor post-cutover outcomes and document process improvements for future carve-in projects.

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 reports
• ATC (ABAP Test Cockpit) results
• ABAP source and DDIC metadata
• Process-event logs and variants
• Requirement traceability matrices
• Data quality assessments
• Connector and interface evidence
• Code compilation and runtime receipts
• Test execution reports
• Cutover reconciliation evidence

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.

• Adranum does not replace SAP licensing or Basis administration.
• Generated code proposals require customer compilation and runtime validation before production use.
• It is not a substitute for specialist SAP testing tools in all scenarios.
• Adranum does not provide official SAP certification or guarantee autonomous production deployment.
