Use this topic map to guide your study for Microsoft MB-800 (Microsoft Dynamics 365 Business Central Functional Consultant) within the Microsoft Dynamics 365 Business Central Functional Consultant Associate path.

  • Set up Business Central: Configure company information, fiscal calendars, number series, and user roles. You must understand how initial setup decisions affect downstream operations and reporting accuracy.
  • Configure financials: Establish chart of accounts, general ledger posting groups, tax settings, and currency handling. Candidates should be able to design posting logic that aligns with organizational accounting policies and compliance requirements.
  • Configure sales and purchasing: Set up customer and vendor hierarchies, item master records, pricing structures, and approval workflows. You'll need to connect these configurations to order processing, invoicing, and payment terms.
  • Perform Business Central operations: Execute daily transactions including sales orders, purchase orders, inventory adjustments, and financial period close activities. Candidates must navigate the system efficiently and troubleshoot common operational issues.

Question Formats & What They Test

The MB-800 exam uses multiple question types to assess both conceptual knowledge and practical decision-making in real Business Central scenarios. Questions progress in difficulty and require you to apply configuration logic to business problems.

  • Multiple choice: Test understanding of core definitions, feature behavior, system terminology, and configuration best practices.
  • Scenario-based items: Present realistic business situations where you analyze requirements and select the correct configuration approach or operational procedure.
  • Simulation-style questions: Require navigation through Business Central menus, completing setup tasks, or interpreting system output to solve a given problem.

Each question type emphasizes practical application, ensuring you can translate business requirements into working configurations and handle operational workflows with confidence.

Preparation Guidance

Effective preparation follows a structured, topic-based approach combined with regular practice and review cycles. Allocate study time proportionally to the four core domains, then reinforce connections between setup, configuration, and operations.

  • Map Set up Business Central, Configure financials, Configure sales and purchasing, and Perform Business Central operations to weekly study blocks and track progress against each domain.
  • Work through practice question sets; review detailed explanations to identify knowledge gaps and reinforce reasoning behind correct answers.
  • Link configuration decisions across planning, execution, and reporting workflows to build a holistic understanding of how Business Central processes interact.
  • Complete a timed mini mock exam 3-5 days before your test date to build pacing confidence and identify final weak areas.

Frequently Asked Questions

Which topics typically carry the most weight on the MB-800 exam?

Configure financials and Perform Business Central operations account for a significant portion of the exam. These domains test both your configuration depth and your ability to execute real-world transactions. However, all four topics are tested, so balanced preparation across Set up Business Central, Configure sales and purchasing, and the other domains is essential for a strong score.

How do the four core topics connect in an actual Business Central project?

Set up Business Central establishes the foundation (company structure, number series, roles). Configure financials and Configure sales and purchasing build on that foundation by defining how transactions post and flow through the system. Perform Business Central operations applies all three to daily work: creating orders, processing invoices, and closing periods. Understanding these connections helps you see why a setup decision in one area affects operations downstream.

How much hands-on experience do I need, and which labs should I prioritize?

Hands-on experience is valuable but not mandatory if you study strategically. Prioritize labs that cover chart of accounts setup, customer and item master configuration, and end-to-end order-to-cash workflows. If time is limited, focus on Configure financials and Configure sales and purchasing labs, as these directly align with high-weight exam content and build confidence in the system interface.

What are common mistakes that cost candidates points on MB-800?

Many candidates confuse posting groups, dimension logic, or approval workflow setup and select answers that work in one scenario but not another. Others rush through scenario questions without fully reading the business requirement. A third common error is underestimating the importance of Perform Business Central operations; candidates who study only configuration without practicing transaction execution often miss operational nuances tested on the exam.

What is an effective review strategy in the final week before the exam?

In your final week, shift from learning new content to reinforcing weak areas and building speed. Retake practice tests in timed mode, review incorrect answers, and create a one-page reference sheet for key configuration decisions (e.g., posting group logic, tax setup). Spend 30 minutes the day before your exam reviewing that reference sheet and doing a quick mental walkthrough of a full order-to-cash scenario, then rest well the night before.
