TL;DR
MB-800 questions describe a job someone needs done in Business Central and ask which page, setting, or tool handles it. This sheet flips the usual domain-by-domain structure and organizes by the job itself — "I need to fix a posted invoice" instead of "Financials domain" — because that's the shape the real questions come in. Pair it with our free MB-800 practice questions to see how these mappings actually get tested.
1. Getting a New Company Ready
Every MB-800 scenario that opens with "a new client is implementing Business Central" is testing this table. Get the company shell and its data right before anything else gets configured on top of it.
| Task | Where it happens |
|---|---|
| Stand up a new company fast, with guided setup steps | Assisted Setup |
| Plan and track configuration decisions across an implementation | Configuration Worksheet |
| Move a tested configuration into a new/second company | Configuration Package |
| Bring in starting G/L balances without re-posting history | Journal opening balances |
| Bring master data and transactions in from another system or company | Data migration (RapidStart / Configuration Package) |
| Turn on built-in Copilot or agent capabilities for a role (e.g., sales line assistance) | Copilot & Agent Capabilities (Feature Management) |
2. Controlling Who Can See or Do What
| Task | Where it happens |
|---|---|
| Create a new person's login and default profile/role center | Users page + User Profile |
| Define exactly which objects/actions a role can touch | Permission Sets |
| Restrict a user to only their own dimension/location data | Security Filters (on a permission set) |
| Assign the same bundle of permissions to many users at once | Security Groups |
| Track who changed what, for compliance | Security Auditing |

This is the single most-tested setup area on MB-800. Almost every "posted to the wrong account" scenario traces back to one row in this table, not a bug.
| Task | Where it happens |
|---|---|
| Set fiscal periods, rounding, and base G/L behavior | General Ledger Setup |
| Decide which revenue/expense account a customer+item combination hits | General Posting Setup (business + product posting groups) |
| Route a specific customer's or vendor's balance to a specific control account | Customer/Vendor Posting Groups |
| Set which inventory/COGS accounts a warehouse's postings use | Inventory Posting Setup |
| Group accounts for financial statement reporting | Account Categories & Subcategories |
4. Tracking Cost Centers, Departments, or Projects
| Task | Where it happens |
|---|---|
| Require a dimension value on every posting company-wide | Global Dimensions |
| Add reporting granularity without touching every posted document | Shortcut Dimensions 3-8 |
| Auto-fill a dimension based on the customer, item, or account used | Default Dimensions (per master record or account type) |
| Prevent an invalid dimension pairing (e.g., a department posting to the wrong project) | Dimension Combinations (blocked) |
5. Requiring Approval Before Something Posts
| Task | Where it happens |
|---|---|
| Require sign-off before a purchase order or journal releases | Native Workflows |
| Alert an approver that something is waiting on them | Notification Setup |
| Define which people belong to an approval chain | Workflow User Groups |
6. Processing a Sale or Purchase
| Task | Where it happens |
|---|---|
| Send a non-binding price offer before an order exists | Sales/Purchase Quote |
| Commit to an order that will ship/receive over time against one agreement | Blanket Sales/Purchase Order |
| Bill in advance for revenue/expense that spans future periods | Deferral Templates |
| Avoid re-typing an order that repeats on a schedule | Recurring Sales/Purchase Lines |
| Bill a customer once for several shipments already sent | Combine Shipments (into one invoice) |
7. Fixing Something Already Posted
| Task | Where it happens |
|---|---|
| A posted sales/purchase invoice has the wrong line or amount | Correct (creates offsetting credit memo + new invoice) |
| A posted entry has the wrong dimension only — everything else is right | Dimension Correction Tool |
| An item shipment or receipt shouldn't have happened at all | Reverse Shipment/Receipt |
| A payment was matched to the wrong invoice | Apply Entries / Undo Application |
| A whole recurring or general journal batch posted incorrectly | Reverse Posted Journal |
8. Managing Inventory and Cost
Costing method is set per item, not per company, and it decides what "cost of goods sold" means every time that item ships. Get this table straight before touching value entries.
| Costing method | Use when… |
|---|---|
| FIFO | Oldest inventory cost is consumed first — typical for perishable or lookalike goods. |
| Average | Cost is smoothed across all units on hand — common for bulk/commodity items. |
| Standard | A predetermined cost is used and variances are tracked separately — manufacturing-style control. |
| Specific | Each unit's exact, individual cost is tracked — serialized or high-value unique items. |
| LIFO | Most recently received inventory cost is consumed first — least common, but still testable. |
| Task | Where it happens |
|---|---|
| See the quantity movement of an item, separate from its cost | Item Ledger Entries |
| See the cost/value side of an item movement | Value Entries |
| Track the same item differently per warehouse/location | Stockkeeping Units (SKUs) |
| Move stock from one warehouse to another | Transfer Order |
9. Tracking Fixed Assets
| Task | Where it happens |
|---|---|
| Group assets that depreciate the same way | Depreciation Books |
| Organize assets by type for reporting/posting defaults | Fixed Asset Classes & Subclasses |
| Track a large asset made of separately-tracked parts | Main Assets & Components |
| Record buying, depreciating, or selling an asset | FA Journal (Acquisition / Depreciation / Disposal) |

10. If the Question Says X, Think Y
| If the question says… | Think… |
|---|---|
| "without reversing the original transaction" | Dimension Correction Tool, not a full reversal |
| "discovered after go-live, without changing every posted entry" | Shortcut Dimension, not Global Dimension |
| "same order shipped/received over several deliveries" | Blanket Order, not a plain Sales/Purchase Order |
| "revenue recognized over future months" | Deferral Template, not a straight posting |
| "exact unit cost of a serialized item" | Specific costing method, not Average or FIFO |
| "a role should only see their own department's data" | Security Filter on the permission set, not a new permission set alone |
| "must be approved before it can post" | Workflow + Workflow User Group, not a manual process note |
