SAP CVI Migration: Workflow and Evidence Guide

Decision context

SAP Customer Vendor Integration (CVI) is a critical process in the system conversion from SAP ECC to SAP S/4HANA, consolidating customer and vendor master data into a unified business partner model. This migration involves complex data transformations, dependency mappings, and compliance with SAP's evolving data governance standards. Effective CVI migration requires detailed readiness assessment, change impact analysis, and controlled execution to minimize business disruption.

Adranum specializes in governed ERP modernization with a focus on SAP change, providing a comprehensive platform to ingest authorized SAP readiness, ABAP, DDIC, and process-event evidence. It supports the mapping of observed and inferred dependencies specific to CVI objects and processes, enabling precise keep/replace/remediate/retire decisions for master data and related custom code.

By integrating process-event and data-quality evidence, Adranum facilitates immutable simulations and improvement history tracking for CVI migration. Its capability to generate reviewable proposals and implementation packages ensures that migration steps are transparent, auditable, and aligned with customer-controlled compilation and runtime validations.

Understanding SAP CVI Migration Challenges

The SAP CVI migration replaces traditional customer and vendor master records with the business partner approach in S/4HANA, requiring data harmonization and transformation across modules. This process introduces dependencies between master data, transactional data, and custom ABAP code that must be carefully analyzed to avoid runtime errors.

Common challenges include incomplete readiness evidence, unsupported customizations, and untracked dependencies that can cause migration failures or post-migration data inconsistencies. Additionally, coordinating cutover activities and reconciliation is complex due to the intertwined nature of business partner data.

Adranum addresses these challenges by ingesting multiple evidence sources to provide a holistic view of the CVI migration landscape, highlighting unsupported inputs and mapping dependencies to guide remediation and replacement decisions.

• Data harmonization between customer, vendor, and business partner objects
• Dependency mapping of ABAP code and DDIC elements related to CVI
• Identification of unsupported or missing readiness inputs

Adranum’s Role in CVI Migration Governance

Adranum acts as a central governance platform that coordinates CVI migration activities by generating content-addressed implementation packages and impacted test lists. It records human approvals to ensure compliance and traceability throughout the migration lifecycle.

The platform supports exact-state recovery and continuity, enabling rollback and reconciliation in case of migration discrepancies. This capability is essential for complex CVI scenarios where data integrity and business continuity are paramount.

By keeping raw service data, source, and credentials within the customer’s infrastructure, Adranum ensures data sovereignty while returning bounded commands and aggregate outcomes, balancing security with operational efficiency.

• Generation of reviewable code and data transformation proposals
• Coordination of cutover, reconciliation, and exact-state recovery
• Recording and tracking of human approvals for compliance

Process Capabilities Tailored for CVI Migration

Adranum’s process-event ingestion captures observed variants and bottlenecks in CVI-related processes, enabling immutable simulations that predict migration outcomes without impacting production systems.

Improvement history tracking allows teams to document and analyze remediation efforts over time, ensuring continuous refinement of migration strategies.

These process capabilities provide actionable insights that reduce risks associated with CVI migration and support informed decision-making.

• Observed process variants and bottleneck identification
• Immutable simulations for risk-free migration testing
• Improvement history documentation for continuous process refinement

Integration with SAP Readiness and ABAP Evidence

Adranum ingests SAP readiness checks, ATC results, ABAP and DDIC artifacts, and abapGit repositories to build a comprehensive evidence base for CVI migration.

This integration enables the identification of unsupported custom code and dictionary objects that may impede the CVI transformation, facilitating targeted remediation.

The platform’s ability to map dependencies between these artifacts ensures that all related objects are accounted for in migration planning.

• Ingestion of SAP readiness and ATC evidence
• Analysis of ABAP and DDIC dependencies
• Identification of unsupported custom objects

Ensuring Data Quality and Compliance

Data quality evidence ingestion allows Adranum to detect inconsistencies and gaps in master data critical to CVI migration success.

The platform supports compliance by maintaining detailed reconciliation evidence and audit trails for all migration activities.

This ensures that the migrated business partner data meets SAP’s standards and internal governance policies.

• Data quality checks on master data
• Reconciliation evidence generation
• Audit trail maintenance for migration activities

What the workflow must cover

• Dependency Mapping for CVI Objects. Adranum maps observed and inferred dependencies between customer, vendor, and business partner master data and related ABAP code, enabling precise impact analysis and remediation planning.
• Reviewable Migration Proposals. The platform generates code and data transformation proposals that are reviewable and editable, ensuring that migration steps align with business requirements and technical constraints.
• Content-Addressed Implementation Packages. Adranum creates immutable, content-addressed packages that encapsulate migration changes, facilitating consistent deployment and rollback if necessary.
• Process-Event Simulation and Bottleneck Analysis. By simulating process variants and identifying bottlenecks, Adranum helps teams anticipate migration risks and optimize cutover strategies.
• Human Approval Recording and Compliance Tracking. All migration decisions and approvals are recorded within Adranum, providing a transparent audit trail that supports governance and compliance requirements.
• Exact-State Recovery and Continuity Coordination. Adranum coordinates cutover, reconciliation, and exact-state recovery steps to maintain business continuity and data integrity during CVI migration.

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 SAP readiness, ATC, ABAP, DDIC, and data quality evidence related to CVI objects.
2. Analyze dependencies and identify unsupported or missing inputs impacting CVI migration.
3. Generate reviewable code and data transformation proposals for business partner consolidation.
4. Record human approvals on proposed migration steps and remediation plans.
5. Create content-addressed implementation packages encapsulating approved changes.
6. Coordinate cutover activities, including reconciliation and exact-state recovery processes.
7. Monitor process-event simulations and bottleneck analyses to refine migration execution and ensure continuity.

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 reports specific to CVI
• ATC results highlighting ABAP code issues affecting business partner objects
• ABAP and DDIC source code repositories with CVI-related customizations
• Data quality reports on customer and vendor master data
• Process-event logs capturing CVI transaction variants and bottlenecks
• Human approval records for migration proposals
• Content-addressed implementation package manifests
• Reconciliation and cutover execution logs
• Simulation reports from immutable process-event analyses
• Audit trails documenting migration decision history

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 required for CVI migration.
• Generated migration proposals require customer-controlled compilation and runtime validation before production deployment.
• The platform does not substitute specialist testing tools for all CVI-related test scenarios.
• Missing or incomplete evidence inputs remain visible and may impact migration completeness.
