SAP MDG Interview Questions for Functional and Technical Consultants

This guide is for you if you are studying sap mdg interview questions or if you are already applying for jobs in sap mdg. SAP Master Data Governance (MDG) is among the rapidly improving areas of the SAP ecosystem. Certified professionals are in demand internationally to administer, control, and sustain global enterprise master data.

This guide is designed for both SAP MDG functional and technical consultants. As such, it includes core concepts and even sap mdg technical interview questions, enabling you to interview successfully and get MDG functional consultant jobs with the best firms.

What Is SAP MDG and Why Does It Matter?

SAP Master Data Governance (MDG) is focused on the management of master data and provides a centralized solution to its customers via the SAP ABAP stack. It enables enterprises to consolidate, control, and provide master data to other enterprise systems. From a governance viewpoint, MDG assists its customers in maintaining data quality, integrity, and compliance.

Large enterprises with large-scale ERPs rely on MDG to govern data across several critical domains, including:

• SAP MDG Material Master
• Business Partner / Customer / Vendor
• Financials (Cost Center, GL Account, Profit Center)
• Custom Objects

Governance of data is becoming an operational and regulatory priority in all sectors. Consequently, the skills related to data governance are among the most sought-after skill sets in SAP careers.

Important SAP MDG Interview Questions for Functional Consultants

For sap mdg functional consultant jobs, expect business process, configuration, and workflow design questions.

1. What are the main components of SAP MDG?

The main components of SAP MDG are:

• MDG Framework – The technical foundation for data models, user interfaces, workflow, and consolidation.
• MDG for Finance – Master data management of financial data such as General Ledger accounts, cost centers, and profit centers.
• MDG for Material – Master data for materials across procurement, production, and sales.
• MDG for Business Partner – Master data for customers, vendors, and suppliers.
• MDG for Custom Objects – Organizations can manage custom (non-standard) master data objects.

2. Consolidation vs. Central Governance in MDG?

This is a very common sap mdg interview question:

3. What is a Data Model in SAP MDG?

A Data Model describes how master data is structured in MDG. It includes:

• Entity Types (Material, Customer, etc.)
• Attributes (fields associated with each entity)
• Relationships between Entity Types

SAP provides standard SAP MDG Data Model (BP, FI, MM), and clients may implement their own data models in MDG Customizing.

4. What is the MDG Workflow and Approval Process?

Mapping flexible or classic workflows in SAP Business Workflow, MDG uses change request workflows using approval hierarchies. The workflows are designed to:

1. Generate change requests
2. Validate data and start workflows
3. Approve/reject requests
4. Activate data and replicate it to target systems after final approval

5. What is an Edition in SAP MDG?

An Edition is a grouping mechanism in MDG that allows the mass change of requests. It is useful in consolidation workflows to provide parallel governance for several requests.

6. How does MDG use data quality?

MDG ensures data quality by:

• Setting validation rules at the field and entity levels
• Creating derivation rules for automatic population of dependent fields
• Performing duplicate checks using the MDG search and SAP NETWEAVER
• Implementing data quality improvement workflows to address existing errors

7. What are the Search and Duplicate Check functions in MDG?

In MDG, SAP NetWeaver Search and Classification (TREX) or SAP HANA provide:

• Full-text searches of master data
• Duplicate detection using fuzzy logic
• Duplicate creation prevention

8. What do Key Mapping and Value Mapping achieve in MDG?

• Key Mapping – During data replication, Key Mapping ensures that MDG data is aligned to the system of the External Legacy System by mapping the MDG internal key to the external system keys.
• Value Mapping – When code list values between external systems (e.g. language codes, country codes) are aligned, MDG internal code list values are also aligned.

SAP MDG Technical Interview Questions

sap mdg technical interview questions for developers and technical architects cover ABAP, BRFplus, and Data Replication in detail.

9. What is BRFplus and how is it used in MDG?

BRFplus (Business Rule Framework Plus) is a rule engine in MDG for SAP that helps with:

• Validation – checking the values of fields and business rules
• Derivation – automatically completing a field
• Check – validating completeness and consistency

MDG context requires technical consultants to understand how to create and activate BRFplus applications, functions, and rules.

10. How does MDG Data Replication work?

MDG employs the Data Replication Framework (DRF) to propagate activated master data to downstream systems. The workflow entails the following:

1. A Replication Model is created in the DRF.
2. Upon activation, an outbound message is created.
3. Data is transmitted through IDocs, SOA Web Services, or ALE/IDoc to the target systems (ECC, S/4HANA, external systems).

11. What is an MDG Change Request and what does the technical structure look like?

A Change Request (CR) in MDG is the core object for which governance revolves. From a technical standpoint, the structure consists of the following:

• It is found in the USMD table family.
• It possesses a CR Type, an Entity Type, and a Status.
• It is linked to workflow tasks.
• It has an Edition to which it is associated for grouping.

Notable tables include USMD_CR, USMD_CRHD, and USMD_VALUE_PC.

12. What are the primary ABAP enhancements in MDG?

ABAP enhancements in MDG provide an array of BAdIs (Business Add-Ins):

• MDG_BS_PROCESS_EVT – Event-based processing
• MDG_BS_UI_FIELDSELECTIO – Field selection/hiding
• MDG_BS_DQ_DUPLICATE – Duplicate checks
• MDG_BS_RULE_SERVICE – Rule services
• USMD_RULE_SERVICE – Validation and derivation services

13. What is the Flex UIF in MDG, and what does the configuration look like?

The Flex UI Framework utilizes Floorplan Manager (FPM) in constructing the web UI for MDG. Configuration is performed through:

• Web Dynpro ABAP
• GUIBB (Generic UI Building Blocks) components
• AET (Application Enhancement Tool) is used to add custom fields.
• Screen configuration is performed in MDG Customizing under UI Modeling.

14. What is the procedure for handling Custom Entity Types in MDG?

Creation of a Custom Entity Type in MDG entails the following actions being performed:

1. A custom data model is defined in MDG Customizing.
2. Creation of database tables for staging and active areas.
3. Configuration of Entity Types, Attributes, and Relationships.
4. Assign screens in FPM.
5. Create BRFplus validations.
6. Set up DRF replication for the newly created object.

15. What is the difference between the Staging Area and the Active Area in MDG?

After workflow approval, data is transferred from Staging Area to Active Area. Technical tables are prefixed differently for each area.

Advanced SAP MDG Interview Questions

16. How does MDG integrate with S/4HANA?

In an S/4HANA landscape:

• MDG runs embedded on S/4HANA or as a Hub deployment.
• SOAP/REST APIs are used for integration.
• Business Partner is the unified object that replaces Customer/Vendor.
• MDG for Finance takes advantage of Fiori apps for governance.

17. What are the deployment options for SAP MDG?

SAP MDG supports three deployment models:

• Hub Deployment – MDG runs on a separate server and governs multiple satellite systems.
• Co-Deployment – MDG runs on the same server as ECC/S/4HANA.
• MDG Cloud – Part of SAP's cloud strategy, integrated with BTP.

18. What is Mass Processing in MDG?

Mass Processing allows bulk creation or updates of master data records in MDG and is typically used for:

• Migration projects.
• Organizational change projects (e.g., change in company code).
• Data cleansing projects.

It uses Editions and batch-processing workflows.

19. What is the function of Process Agents in an MDG Workflow?

Process Agents specify who will receive a workflow task for each step. MDG supports:

• Rule-based agents that use BRFplus
• Master data attributes define the responsible person
• Routing based on the organizational hierarchy
