Data Replication
Covers how SAP Master Data Governance distributes governed, approved master data to connected target systems (ERP/S4HANA, CRM, BW, non-SAP consumers) through the Data Replication Framework: replication models, filters, outbound implementations, mapping, monitoring, and error handling, along with on-premise vs cloud distribution differences.
Overview
Covers how SAP Master Data Governance distributes governed, approved master data to connected target systems (ERP/S4HANA, CRM, BW, non-SAP consumers) through the Data Replication Framework: replication models, filters, outbound implementations, mapping, monitoring, and error handling, along with on-premise vs cloud distribution differences.
Lessons in this topic
- SAP MDG Data Replication Tutorial (Part 1)Understand why governance without replication is incomplete, and how MDG moves an approved master record out of the central hub into consuming systems.
- Configuring Replication Models, Filters and Outbound Implementations (Part 2)Learn the practical configuration building blocks used to set up replication for a governed object: replication model, filter criteria, outbound implementation assignment, and mapping considerations.
- Monitoring, Troubleshooting, and Reprocessing Failed Replication Loads (Part 3)Learn how to monitor outbound replication after change request activation, diagnose common failure categories, and safely reprocess failed distribution loads without corrupting target systems.
- MDG Data Replication Architecture: DRF, Filters, Key Mapping and Recovery (Part 4)Design and troubleshoot MDG replication as a governed distribution process with explicit target models, filters, key mapping, monitoring and safe recovery.
Interview questions covered
- A project encounters this situation while working on Configuring Replication Models, Filters and Outbound Implementations: During a business partner rollout, the project team configured a replication model to two target systems: an S4HANA production system and a CRM system. Walk through how you would analyze the requirement or issue, what you would validate, and how you would test the solution before release.
- A project encounters this situation while working on Monitoring, Troubleshooting, and Reprocessing Failed Replication Loads: During a phased rollout of a new plant, several material master change requests were activated in MDG and confirmed as successfully governed, but two weeks later the plant's MRP team reported that dozens of materials were missing in their local ERP system. Walk through how you would analyze the requirement or issue, what you would validate, and how you would test the solution before release.
- Using this SAP project situation — A retail company centralizes business partner governance in MDG so that customer master data is created once, validated, deduplicated, and approved before use — explain Why Replication Matters in MDG: From Governed Record to Distributed Data. What should happen, which concepts or process steps matter, and what common mistake would you avoid?
- What are the core concepts of SAP MDG Data Replication, and how would you explain them clearly in an SAP interview?
- How would you apply SAP MDG Data Replication in a real SAP project? Walk through the design or implementation approach.
- A production issue is reported in SAP MDG Data Replication. What would you check first, and how would you troubleshoot it systematically?
- What are the most important design decisions, trade-offs, and best practices in SAP MDG Data Replication?
- Suppose you inherit an existing SAP MDG Data Replication solution. How would you review it before making a change?
- A senior architect is reviewing SAP MDG Data Replication. The project situation is: A governed BP was approved in MDG but never appeared in one regional S/4 system. What design changes, validation evidence and production controls would you require before approving the solution?
