Business Central knowledge graph
A map of a family of Microsoft Dynamics 365 Business Central products, built every night straight from their AL source code and API contracts. It shows where the apps meet: whether they can be installed side by side, which standard tables, codeunits and events several of them depend on, which features have no tests, and how much of an API contract is implemented.
Partners who sell several apps meet the same problems at the customer. Two per-tenant extensions that share an object ID cannot be installed together, and apps that hook into the same posting routines affect each other in ways no single repository shows. This page checks all the apps at once.
bc-knowledge-graph reads each repository: object declarations, table fields, event subscriptions, API pages, feature documents, test plans and OpenAPI/AsyncAPI contracts. It links them into one graph. Nothing is compiled, deployed or run, and no Business Central environment is needed.
The tool is open source. Point it at your repositories to get this page for your apps, ask Claude about them in plain language through its MCP server, or explore the graph in Neo4j. Get started on GitHub.
What the graph was built from. Each app owns its own object ID range; its tests are counted with it.
Native CRM in Business Central - record ownership and teams, an activity timeline, opportunities, a guided sales process, a product catalog and pricing, with no Dataverse.
Tests in CRM Tests (8 codeunits)
Headless commerce on Business Central - a storefront and domain services, an Azure integration layer and an AL connector, joined by versioned OpenAPI and AsyncAPI contracts.

No test app
API contracts: erp-commerce@1.0.0erp-events@1.0.0
A construction vertical on standard Business Central Projects - estimating, cost control, scheduling, progress billing, retention, subcontracts and plant.
Tests in Construction Management Tests (15 codeunits)
High-volume invoice import and batch posting - a Rust ingestion service and an AL extension that posts through Business Central's supported APIs.
No test app
Advanced warehouse management for Business Central Cloud, beyond the standard app.
Tests in Warehouse Advanced Tests (21 codeunits)
A complete Serbian localization for Business Central W1 (version 29), built as one per-tenant extension on the standard E-Document framework.
The repository is private: its code is not part of the graph above, and access is available on request.
Which object IDs are used by more than one app?
Per-tenant extensions that declare the same object ID cannot be installed in the same environment. Give every app its own ID block.
Nothing found.
Which fields do different apps add to the same table with the same ID or name?
Either clash stops the second table extension from installing.
Nothing found.
For each pair of products, how many standard objects do both of them extend, subscribe to or use?
The higher the number, the more a customer running both needs them tested together. Test apps are left out.

Which features does nothing test?
No test procedure is named in the feature's test plan and no test codeunit uses any of its objects.

Which contract operations does no AL object serve, and which channels does nothing in BC emit?
The work left to connect the contract to Business Central.
| contract | kind | name | detail |
|---|---|---|---|
| erp-commerce@1.0.0 | operation | checkAvailability | POST /availability/check |
| erp-commerce@1.0.0 | operation | getCatalogueHashes | GET /catalogue/reconciliation |
| erp-commerce@1.0.0 | operation | getCatalogueItemsDelta | GET /catalogue/items |
| erp-commerce@1.0.0 | operation | getCategoryTree | GET /catalogue/categories |
| erp-commerce@1.0.0 | operation | getCreditStanding | GET /customers/{customerId}/credit |
| erp-commerce@1.0.0 | operation | getListPricesDelta | GET /catalogue/prices |
| erp-commerce@1.0.0 | operation | resolvePrices | POST /pricing/resolve |
| erp-commerce@1.0.0 | operation | submitOrder | POST /orders |

| erp-events@1.0.0 | channel | inventory.stock.changed | |
| erp-events@1.0.0 | channel | sales.order.statusChanged |
Is every repository built against the current contract version?
A pinned version that differs from the contract repository's version is drift.
| repo | pinned | contract | current | drift |
|---|---|---|---|---|
| commerce-integration | 1.0.0 | erp-commerce | 1.0.0 | no |
| commerce-integration | 1.0.0 | erp-events | 1.0.0 | no |
These need an input, so they are not on this page. Ask them with bckg ask or through the MCP server.
| question | ask | parameter |
|---|---|---|
| feature_trace | What implements a feature, what tests it, and what does it touch? | feature: feature code, for example FEAT-WGT-001 |
| contract_impact | What does a change to one contract property touch? | property: Schema.property, for example Category.parentId |
If you build or sell several Business Central apps, the same questions apply to you: can they be installed for the same customer, where do they touch the same standard objects and events, and which features are untested.
The tool is free and open source, so you can run it on your own repositories today. If you would rather have someone check your apps before a customer installs them together, or keep a graph like this one current for your team, get in touch.
