C_MDG_90 Exam Guide: Skills, Prerequisites, Study Plan, and Scheduling Decisions
C_MDG_90 is identified by SAP Community as the certification identifier for SAP Master Data Governance consulting certification. The subject is SAP MDG: governing the creation, change, distribution, consolidation, and central management of master data across a system landscape. It is most relevant to consultants and professionals working with SAP master-data processes, governance, and solution design. This guide helps you decide whether your background is ready, whether to study business processes or configuration first, which official learning resources to use, and what to verify before booking an attempt.
What C_MDG_90 validates
C_MDG_90 is associated with SAP Master Data Governance consulting. SAP describes certification as a performance-based credential that validates expertise, while its MDG material focuses on controlled master-data processes across an enterprise landscape. Prepare to explain how those processes work and why particular governance, quality, and distribution choices are used—not merely to recall product terminology.
The central capability: controlled master data
SAP Master Data Governance supports the creation, change, distribution, consolidation, and central management of master data. That description gives you a useful study lens: understand the business request, the governed data object, the approval or validation path, the resulting quality controls, and the way data reaches connected systems. [https://learning.sap.com/products/business-technology-platform/data-analytics/master-data-governance]
A strong preparation model connects business purpose to system behavior. For example, a request to create or change a business partner should be considered alongside governance responsibilities, validation and derivation rules, workflow decisions, data quality, and distribution requirements. The official material does not supply a public C_MDG_90 blueprint in the supplied sources, so these are evidence-based study areas rather than claimed exam-domain percentages.
The role context
SAP’s Master Data Governance learning journey lists Architect, Administrator, and Consultant among its associated roles. The MDG100 course also names application consultant, business analyst, business process architect, business process owner or team lead or power user, and solution architect as audiences. That range indicates that preparation should combine process understanding with enough technical context to discuss configuration and integration choices. [https://learning.sap.com/learning-journeys/exploring-sap-master-data-governance] [https://training.sap.com/course/MDG100]
Who should consider this certification
The best starting point is practical SAP ERP or SAP S/4HANA master-data experience, especially in Financials, MM, or SD. C_MDG_90 is a poor first SAP credential if you have not worked with enterprise master data or the business processes that consume it. Before scheduling, compare your experience with SAP’s stated prerequisites and decide whether you need business-process training, configuration training, or both.
Background SAP lists as essential
SAP lists experience in SAP Business Suite ERP or SAP S/4HANA and experience with SAP ERP master data in Financials, MM, or SD as essential prerequisites for MDG100. These are course prerequisites rather than a separately published C_MDG_90 eligibility rule in the supplied evidence, so treat them as a practical readiness benchmark, not as an invented exam-admission requirement. [https://training.sap.com/course/MDG100]
If your experience is concentrated in one area, begin there and then broaden deliberately. A Financials specialist should add material and business-partner scenarios; an MM specialist should add financial and customer-related governance concepts; an SD specialist should examine supplier, customer, and business-partner relationships. The aim is not to claim equal project experience in every domain, but to avoid interpreting MDG through one narrow data model.
Background SAP recommends
For MDG100, SAP recommends familiarity with Business Rules Framework Plus, Business Workflow, Floorplan Manager for Web Dynpro ABAP, and Application Link Enabling technology. MDG200 adds SAP ERP Customizing, Web Service technology, and experience in Data Services, Data Quality Management, and Information Steward. Use this distinction to diagnose gaps: recommended knowledge can be learned, but the absence of core SAP master-data experience usually requires more foundational work. [https://training.sap.com/course/MDG100] [https://training.sap.com/course/mdg200-sap-master-data-governance-configuration-and-customizing-classroom-020-g-en]
Which official learning path fits your gap
Choose MDG100 or the SAP Learning course when you need to understand MDG business processes and data domains. Choose MDG200 when you already understand the business flow and need configuration, extension, workflow, data-quality, or replication depth. Combining them is sensible for a consultant who must move between process design and implementation, but do not start with configuration detail if you cannot first describe the governed business outcome.
Use MDG100 for business-process coverage
SAP’s MDG100 course is based on SAP S/4HANA 2023 and is listed as a 5-day course. Its content includes MDG for material; business partner, supplier, and customer; Financials and hierarchy management; mass changes and multiple-object processing; mass processing and consolidation; process analytics; data quality management; and Cloud Ready Mode. SAP states that the course is focused on business processes and that more technical information is provided in MDG200. [https://training.sap.com/course/MDG100]
This is the right anchor when you need a coherent picture of how MDG is used. Build notes around the purpose of each process, the object or domain involved, the people or roles affected, and the quality or distribution problem being addressed. Do not turn the course list into isolated vocabulary cards.
Use the SAP Learning course for a structured first pass
The SAP Learning course SAP Master Data Governance on SAP S/4HANA is listed as an intermediate course with 9 units and 10hr 15min of learning content. Its units cover the MDG introduction, material, business partner, supplier and customer, Financials and hierarchy management, mass changes and multiple-object processing, mass processing and consolidation, process analytics, data quality management, and Cloud Ready Mode. [https://learning.sap.com/courses/sap-master-data-governance-on-sap-s-4hana]
Use this course to establish sequence and terminology before attempting detailed configuration study. After each unit, write a short process explanation from memory. Then identify where your explanation is vague: object scope, governance step, quality control, analytics, or distribution. Those gaps should determine your next reading rather than a fixed study order.
Use MDG200 for implementation-oriented depth
SAP’s MDG200 course is based on SAP S/4HANA 2023 and is listed as a 3-day course. It covers standard-content configuration, extensions and custom content, data modeling, user-experience modeling, process modeling, rule-based workflow, data replication, key and value mapping, hierarchy management, data transfer, validations, search, and duplicate checks. [https://training.sap.com/course/mdg200-sap-master-data-governance-configuration-and-customizing-classroom-020-g-en]
MDG200 is especially useful when your role involves translating a business requirement into an MDG design. Study each technical topic by asking what requirement it solves, what configuration area it affects, and what downstream consequence follows if it is designed incorrectly. This keeps configuration knowledge connected to governance outcomes.
What skills to measure during preparation
Because the supplied official sources do not publish C_MDG_90 domain weights or a question blueprint, measure readiness by capability rather than by unsupported percentages. You should be able to explain MDG’s strategy and deployment context, distinguish major data domains and processes, reason about governance roles and responsibilities, and connect configuration concepts to quality and replication outcomes.
Measure process and domain understanding
Can you explain the difference between governing material data, business partner data, supplier or customer data, Financials data, and hierarchy information? Can you describe why mass processing, consolidation, process analytics, and data quality management exist? The MDG100 outcomes explicitly focus on presenting the solution strategy, explaining data domains and processes, and explaining the business processes used within MDG. [https://training.sap.com/course/MDG100]
Test yourself with a blank page. Choose a domain, state the business problem, outline the governed process, identify the quality concern, and explain how the approved result is used elsewhere. If you can name features but cannot explain the business reason for them, return to the process material.
Measure governance reasoning
The official learning journey expects learners to explain MDG’s purpose and value, describe capabilities and deployment options, identify governance processes, roles, and responsibilities, and outline how controlled creation, maintenance, and distribution improve data quality. Use those outcomes as a checklist for scenario reasoning. [https://learning.sap.com/learning-journeys/exploring-sap-master-data-governance]
A useful test is to compare two approaches to a master-data request: uncontrolled direct maintenance and a governed process. Explain who should provide information, who should validate it, who should approve it, how quality is checked, and how the final record is distributed. Avoid treating governance as only an approval screen; it includes accountability, consistency, quality, and lifecycle control.
Measure configuration and integration understanding
MDG200’s learning outcomes cover basic configuration of standard content, adjustment and extension of standard content, and creation of custom content. Its topic list also includes data modeling, validations, checks and derivations with BRFplus, user-interface modeling, workflow, replication, and mapping. These are the technical capabilities to assess if your target role includes implementation or solution design. [https://training.sap.com/course/mdg200-sap-master-data-governance-configuration-and-customizing-classroom-020-g-en]
Do not measure this area by memorizing transaction names or configuration labels alone. Instead, take a requirement such as a new attribute, a duplicate check, a validation, a derivation, or a replication mapping and explain the design path. Include the data model, rule or process behavior, user interaction, and receiving-system implication where relevant.
A practical study roadmap
Use a staged plan: establish SAP and MDG foundations, map the business domains, add process and quality reasoning, then study configuration and integration only to the depth your role requires. Finish with closed-book scenario practice and an official-source check of current certification arrangements. A longer plan is not automatically better; each stage should produce an observable capability.
Stage one: confirm readiness and define scope
Start by recording your SAP Business Suite ERP or SAP S/4HANA experience, the master-data domains you have handled, and your exposure to Financials, MM, or SD. Mark each area as working knowledge, guided exposure, or unfamiliar. Then compare the list with the MDG100 prerequisites and audience. [https://training.sap.com/course/MDG100]
Next, decide whether your objective is business-process consulting, application consulting, architecture, administration, or configuration. SAP’s learning materials associate MDG with several of these roles, but the amount of technical detail you need will differ. This decision prevents you from spending early study time on topics that do not address your gap. [https://learning.sap.com/learning-journeys/exploring-sap-master-data-governance]
Stage two: build the MDG mental model
Study the introductory MDG material first. Write a one-page model covering the central hub or governance layer, the data lifecycle, the main actors, quality controls, and the relationship between governed data and the wider system landscape. SAP describes MDG as enabling a unified, trusted view and supporting management, mapping, and replication of master data. [https://learning.sap.com/products/business-technology-platform/data-analytics/master-data-governance]
Do not proceed until you can explain why an enterprise would centralize or control master-data activities. A candidate who knows feature names without understanding the data-quality and consistency problem will struggle with scenario-based decisions.
Stage three: study domains in a deliberate order
A useful sequence is material, business partner with supplier and customer relationships, Financials and hierarchy management, then mass processing, consolidation, analytics, and data quality management. This follows the published MDG100 and SAP Learning course coverage while moving from individual domains to cross-domain and operational capabilities. [https://training.sap.com/course/MDG100] [https://learning.sap.com/courses/sap-master-data-governance-on-sap-s-4hana]
For every unit, produce four notes: the business purpose, the governed data, the process or control involved, and the likely impact on consuming systems. Add a fifth note for any unfamiliar prerequisite technology. This format makes revision active and exposes whether you understand relationships between topics.
Stage four: add technical topics selectively
If your role is configuration-heavy, study MDG200 after the business-process foundation. Cover standard configuration, data modeling, extensions, custom content, BRFplus validations and derivations, search and duplicate checks, user-interface modeling, workflow, replication, mapping, and data transfer. If your role is primarily business analysis or process ownership, learn what each area accomplishes and what decisions it influences without attempting to become a developer. [https://training.sap.com/course/mdg200-sap-master-data-governance-configuration-and-customizing-classroom-020-g-en]
Create small design exercises rather than copying definitions. For each exercise, state whether the requirement belongs to the data model, validation or derivation logic, workflow, user experience, search and duplicate control, or replication design. Then explain why the alternatives are less suitable.
Stage five: rehearse explanation, not memorization
Use notes, official course material, and legitimate hands-on practice where available. Close the material and explain a complete scenario aloud or in writing: request, validation, approval, activation, quality review, and distribution. Review errors by capability—domain knowledge, process order, governance responsibility, configuration purpose, or integration reasoning—rather than simply counting missed questions.
Do not use dumps, leaked questions, or memorization as a substitute for competence. They cannot establish that you understand the product, may be inaccurate, and do not prepare you to reason about a process that is presented in a different form.
How to turn official course topics into study tasks
A course catalogue is useful only when it changes what you can do. Convert each official topic into a question, a short design exercise, or an explanation that another consultant could review. This approach gives you evidence of readiness without pretending that the supplied sources reveal the live examination content.
Business-process task
Choose one domain and describe the lifecycle of a master-data request from initiation to use in the landscape. Include the purpose of governance, the roles or responsibilities involved, the quality checks that matter, and the reason distribution must be controlled. Repeat the exercise for a second domain and note what changes.
Data-quality task
Build a small issue log with separate entries for incomplete data, invalid data, duplicate data, inconsistent data, and data that is correct centrally but not correctly distributed. For each entry, identify the MDG capability or process area that should be investigated. Keep the distinction between data-quality management, duplicate checks, validation, and replication clear. The official course material treats these as related but identifiable areas. [https://training.sap.com/course/mdg200-sap-master-data-governance-configuration-and-customizing-classroom-020-g-en]
Workflow and rule task
Take a proposed approval process and write the business rule, the validation or derivation requirement, and the workflow consequence as three separate statements. Then ask what should happen when the rule fails, when additional approval is needed, and when the record must be sent to another system. This prevents the common mistake of treating BRFplus logic, workflow, and replication as interchangeable concepts.
Replication task
Draw a simple source-governance-target flow and annotate the data that must be mapped, the point at which quality is checked, and the outcome if the receiving system uses a different key or value. MDG200 specifically includes data replication, key and value mapping, and replication usage, making this a useful implementation-oriented readiness test. [https://training.sap.com/course/mdg200-sap-master-data-governance-configuration-and-customizing-classroom-020-g-en]
Common preparation mistakes
Most avoidable errors come from studying at the wrong level, confusing adjacent capabilities, or treating a course description as an exam blueprint. Correct those issues before adding more material. A short diagnostic review is usually more useful than another unstructured reading session.
Mistake: treating one course as the complete exam specification
MDG100 and MDG200 describe official training content, not a supplied C_MDG_90 question list or publicly verified blueprint. Use them as structured preparation sources, then verify current certification information in SAP Learning and SAP’s certification overview. Do not assign invented weights to course topics or assume that course duration predicts exam coverage. [https://learning.sap.com/certifications/sap-certified-associate-sap-master-data-governance] [https://www.sap.com/training-certification/sap-certification.html]
Mistake: beginning with configuration before understanding the process
Configuration terms become easier to retain when you know the business problem they solve. Starting with BRFplus, workflow, or data modeling without understanding the governed object and lifecycle often produces fragmented recall. Establish the MDG strategy and domains first, then connect each technical topic to a concrete requirement.
Mistake: ignoring integration and data quality
Master data is valuable only when it remains usable and consistent across the landscape. A study plan focused exclusively on creation screens misses consolidation, analytics, quality management, mapping, and replication. Include at least one end-to-end scenario that follows data beyond the initial request.
Mistake: confusing course prerequisites with current exam rules
SAP’s training pages state prerequisites for MDG100 and MDG200. The supplied evidence does not state a separate current C_MDG_90 prerequisite policy, retirement status, score, duration, question count, or language list. Do not present training prerequisites as official exam-admission rules. Check SAP’s current certification page before purchase or scheduling. [https://www.sap.com/training-certification/sap-certification.html]
Delivery, attempts, and purchase checks
The supplied evidence supports historical delivery information for C_MDG_90 and current general SAP certification purchase options, but it does not establish the current delivery status or terms of this specific exam. Treat scheduling, attempt bundles, access conditions, payment methods, and availability as details to verify directly in SAP’s current certification channels before committing funds.
What the supplied evidence says about delivery
SAP Community states that C_MDG_90 was offered through online exams worldwide and classroom delivery in selected countries and locations. That is a historical statement in the supplied source, not proof that the same arrangements remain available now. Confirm the current listing and delivery method through SAP before scheduling. [https://community.sap.com/t5/technology-blog-posts-by-sap/mdg-consulting-certification-available/ba-p/13358651]
What SAP currently describes generally
SAP’s certification overview lists purchase options providing one exam attempt or six exam attempts. It also describes an option with two exam attempts and 10 hours of certification-relevant hands-on practice-system access, and says SAP Learning Hub includes four certification exam attempts and preparation and maintenance resources. These are general options described by SAP, not a guarantee that every option applies to C_MDG_90. [https://www.sap.com/training-certification/sap-certification.html]
SAP states that payment by invoice is supported for all countries, while credit-card availability depends on the buyer’s country. Check the product page, account eligibility, region, and current terms rather than relying on a general option description. [https://www.sap.com/training-certification/sap-certification.html]
A sensible booking checklist
Before purchasing, confirm that SAP currently lists the intended certification, that the identifier or successor title matches your target, that the selected package applies to the exam, and that the delivery method is available in your region. Record the purchase terms, attempt rules, rescheduling conditions, and any practice-system access details shown in your account. The official SAP certification overview is the appropriate starting point for current commercial information. [https://www.sap.com/training-certification/sap-certification.html]
Training delivery choices
Instructor-led training can be useful when you need guided explanation or access to structured exercises, but it should be chosen for a specific gap. MDG100 supplies business-process grounding, while MDG200 is aimed at configuration and customizing. SAP lists virtual classroom and live classroom formats on the course pages and provides date-request mechanisms, subject to regional conditions and participant thresholds.
When MDG100 is the better investment
Choose MDG100 when you need a complete business view of MDG, lack confidence across several data domains, or need structured practical exercises. SAP says the course includes hands-on exercises and covers the business processes needed for ongoing master-data quality. [https://training.sap.com/course/MDG100]
When MDG200 is the better investment
Choose MDG200 when you already understand MDG processes and need to configure or extend standard content, create custom content, model data, build rules, configure workflow, or design replication. SAP describes it as a configuration and customizing course and lists virtual classroom and live classroom delivery on the course page. [https://training.sap.com/course/mdg200-sap-master-data-governance-configuration-and-customizing-classroom-020-g-en]
How to handle scheduling uncertainty
SAP’s course pages allow requests for training dates. For MDG100, SAP describes requests for one or two people and a separate route for three or more participants; for MDG200, SAP describes its 3 to RUN initiative and notes that scheduling depends on a minimum participant threshold for the region. Treat those as scheduling mechanisms, not guaranteed dates. [https://training.sap.com/course/MDG100] [https://training.sap.com/course/mdg200-sap-master-data-governance-configuration-and-customizing-classroom-020-g-en]
A final readiness review
Schedule only after you can explain MDG without relying on prompts, connect the major domains to business processes, and identify the purpose of the principal quality, workflow, modeling, and replication capabilities. You should also have checked the current SAP certification listing and purchase conditions. Readiness is a judgment based on demonstrated understanding, not on completing a particular number of study hours.
Business readiness test
Explain MDG’s purpose and value to a business stakeholder. Describe controlled creation, maintenance, distribution, and consolidation in plain language. Identify the roles and responsibilities involved in governance. Explain how data quality management and process analytics support ongoing control. These capabilities align with the official learning-journey outcomes. [https://learning.sap.com/learning-journeys/exploring-sap-master-data-governance]
Consulting readiness test
Given a master-data problem, identify the relevant domain, process, quality issue, and landscape impact. Explain what information you would clarify before proposing a solution. Distinguish a process requirement from a configuration choice and a replication requirement from a local data-maintenance issue.
Configuration readiness test
For an implementation scenario, explain whether the likely response involves standard content, an extension, custom content, data modeling, a validation or derivation, duplicate checks, workflow, user-interface modeling, or replication. You do not need to force every topic into every scenario; the test is whether you can select the relevant capability and justify it. [https://training.sap.com/course/mdg200-sap-master-data-governance-configuration-and-customizing-classroom-020-g-en]
Evidence and logistics test
Locate the current SAP Learning certification page, read the current product information, and verify the exam identifier or current certification title shown for your purchase. Confirm delivery and attempt terms in your own region. If you are using training, check the relevant course version and prerequisites rather than assuming that an older community announcement describes current availability. [https://learning.sap.com/certifications/sap-certified-associate-sap-master-data-governance] [https://www.sap.com/training-certification/sap-certification.html]
What to do next
Start with a readiness inventory, then use the official learning journey or SAP Learning course to fill the business-process gaps it reveals. Add MDG200 only where your target role requires configuration or integration depth. After each study block, produce a closed-book explanation or design exercise, review the weak capability, and verify current certification and scheduling information before buying an attempt.
A focused next-action list
First, document your SAP ERP or SAP S/4HANA and master-data experience. Second, select one primary role perspective—consultant, architect, administrator, analyst, or process owner. Third, complete an introductory MDG pass and map the major domains. Fourth, work through end-to-end scenarios involving quality, workflow, and distribution. Fifth, add MDG200 topics if configuration is part of your intended work. Finally, check SAP’s current certification listing and purchase terms.
Conclusion
C_MDG_90 preparation should be built around MDG consulting judgment: understand why master data is governed, how processes differ by domain, how quality is controlled, and how approved data is modeled, approved, and distributed. SAP’s official learning journey, MDG100, MDG200, and certification information provide the evidence base, but the supplied sources do not establish current exam weights or every delivery rule. Use the roadmap to expose knowledge gaps, verify current booking details directly with SAP, and choose training depth according to the role you intend to perform.
