SAP Master Data Governance (C_MDG) — Lesson 3: Duplicate Checks, Search, Matching, Key and Value Mapping, Replication, DRF, and Integration

Learning Objectives

• Explain the SAP structures, data, settings, roles, and dependencies governing master-data matching and replication.
• Perform and validate mapping, DRF, and integration controls using reviewable system evidence.
• Evaluate the condition where a change request completes but downstream data remains inconsistent because validation, workflow, key mapping, duplicate handling, replication, and ownership controls are incomplete and select proportionate corrective action.

Detailed Topics

• Duplicate Checks applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Search applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Matching applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Key and Value Mapping applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• Replication applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• DRF applied to the course scenario, expected SAP behavior, dependencies, and evidence.
• and Integration applied to the course scenario, expected SAP behavior, dependencies, and evidence.

Instructor Demonstration

The instructor traces an enterprise data team governing business partner, material, financial, and custom master data across heterogeneous application landscapes. The walkthrough connects navigation, configuration or process logic, system messages, and evidence captured in the C_MDG governance model, change-request, quality, replication, and operations workbook. It also tests the exception where a change request completes but downstream data remains inconsistent because validation, workflow, key mapping, duplicate handling, replication, and ownership controls are incomplete.

Hands-On Exercise

Complete a controlled SAP exercise covering Duplicate Checks, Search, Matching, Key and Value Mapping, Replication, DRF, and Integration and preserve the verified result in the C_MDG governance model, change-request, quality, replication, and operations workbook.

1. Confirm scope, prerequisites, master data, roles, dependencies, and acceptance criteria.
2. Execute the workflow while recording settings, transactions, outputs, and system messages.
3. Test normal behavior, one boundary condition, and the stated exception.
4. Document corrections, evidence, ownership, retest criteria, and handover actions.

Scenario Analysis

• Identify which object, rule, setting, or process step most strongly influences master-data matching and replication.
• Compare two defensible responses and explain business, technical, control, and support trade-offs.
• Determine how the C_MDG governance model, change-request, quality, replication, and operations workbook should be approved, retained, retested, and updated.

Troubleshooting Guidance

Start where expected SAP behavior first differs from the observed result. Check master data, configuration sequence, authorization, integration, status, and transaction evidence separately. Treat “a change request completes but downstream data remains inconsistent because validation, workflow, key mapping, duplicate handling, replication, and ownership controls are incomplete” as a hypothesis until system settings, logs, documents, and outcomes confirm the cause.

Validation Checklist

• Required SAP structures, master data, roles, settings, and dependencies are present.
• The C_MDG governance model, change-request, quality, replication, and operations workbook connects each conclusion to objective, reviewable evidence.
• Normal processing, the boundary condition, integration behavior, and exception were tested.
• Corrections, ownership, retest criteria, documentation, and operational handover are complete.

Lesson Outcome

Learners can apply Duplicate Checks, Search, Matching, Key and Value Mapping, Replication, DRF, and Integration, explain the resulting SAP behavior, and defend the outcome through the C_MDG governance model, change-request, quality, replication, and operations workbook.
