Many professionals believe a Navision course is mainly about learning the familiar menus of an older ERP system. That view can lead teams toward outdated material and away from the skills needed for Microsoft Dynamics 365 Business Central projects.

Navision became Dynamics NAV and then evolved into Microsoft Dynamics 365 Business Central, Microsoft’s cloud-first ERP platform for small and mid-sized organisations. The naming still matters because many finance, operations, and supply chain professionals search for “Navision” when they actually need Business Central training that reflects current releases, AL extensions, integrations, and modern configuration practices.

Why the Navision name still matters

The older Navision and Dynamics NAV heritage remains visible in many businesses. Chart of accounts structures, posting groups, item costing habits, and month-end routines often originated years before a Business Central migration. A training plan that ignores that history can feel disconnected from the way organisations actually work.

At the same time, treating Business Central as if it were only a renamed NAV system creates risk. The modern product is designed around cloud updates, extensions, integrations, and standard application behaviour. Microsoft’s current documentation and Learn materials place Business Central in the Dynamics 365 ecosystem, so training should prepare learners for the product as it is used now rather than for legacy customisation patterns.

The practical difference is most visible in customisation. Older NAV environments were often changed directly through C/AL customisations, sometimes deeply embedded in the base application. Business Central development is built around AL extensions, Visual Studio Code tooling, events, APIs, and an approach that keeps the base application updateable. Functional learners do not need to become developers, but they do need to understand why a configuration decision, an extension, and a base-app modification are not interchangeable.

The skills that turn ERP training into operational value

Business Central training is most useful when it mirrors the work people perform during an implementation or improvement project. A finance manager may need to understand dimensions, posting setup, bank reconciliation, fixed assets, approvals, and the month-end close. A supply chain manager may focus on item cards, costing methods, replenishment, warehouse flows, purchase orders, and stock adjustments. A solution owner may need enough breadth to connect finance, sales, purchasing, and operations into a coherent process design.

Consider a month-end close that regularly depends on spreadsheet checks outside the ERP system. The issue may not be that users lack general ERP awareness. It may be that dimensions are inconsistently applied, posting groups were copied without enough review, approvals are bypassed, or inventory costs are not understood before journals are posted. Training that works through these scenarios helps learners see how small setup decisions affect reporting, reconciliation, and confidence in the numbers.

This is also how many hiring managers and project leads assess Business Central capability. They often look beyond whether a candidate can navigate pages and ask scenario-based questions: how to correct a posting setup issue, how dimensions flow into reporting, what happens when inventory costing is adjusted, or how an approval workflow should be tested before go-live. A course built around real tasks gives learners better preparation than a tour of screens alone.

Choosing between MB-800 and a developer path

The MB-800 exam, Microsoft Dynamics 365 Business Central Functional Consultant, is the clearest certification route for professionals who own business processes, configuration, and user-facing implementation decisions. Microsoft describes the related role around setting up Business Central and configuring areas such as financials, sales, purchasing, and operations. In practical terms, that fits finance and operations professionals, functional consultants, business analysts, and solution owners who need to translate business requirements into working ERP setup.

A developer path is different. It is more relevant when the role involves building AL extensions, integrating Business Central with other systems, working with APIs, using Visual Studio Code, or supporting AppSource-style extensibility. NAV veterans who previously worked with C/AL should be especially careful here: the modern learning priority is not to preserve old customisation habits, but to understand the extension model and how to keep environments maintainable through cloud updates.

Some projects require both paths, but they should not be blended casually. A functional consultant needs to know when to configure, when to challenge a requirement, and when to involve a developer. A developer needs enough functional context to avoid building extensions that undermine posting logic, costing, approvals, or reporting. Readers who want a structured functional route can review the MB-800 Business Central Functional Consultant course, while technical learners working with extensions may be better served by a Business Central Developer AL course.

Practice should happen in a sandbox, not in theory

Business Central is difficult to learn well from slides alone. Learners need a safe environment where they can make setup choices, post transactions, reverse mistakes, and inspect the downstream impact. A sandbox with CRONUS sample data is useful because it gives learners realistic customers, vendors, items, accounts, and transactions without risking live business records.

A practical practice plan should include more than opening pages and reading fields. Learners should create or review posting groups, assign dimensions, process sales and purchase documents, post journals, test approval workflows, and compare reports before and after transactions. They should also document what changed and why, because ERP competence depends on traceability as much as task completion.

Power Automate approvals are a good example of where practice reveals hidden assumptions. An approval may appear simple until the team tests substitute approvers, rejected requests, missing dimensions, or a user without the right permissions. The sandbox is where those issues should surface. The same applies to inventory costing: a learner should see how item setup, costing method, receipts, shipments, and adjustments shape the financial outcome before that logic affects a live close.

Common mistakes when updating from NAV to Business Central

The most common learning mistake is following material that still treats Dynamics NAV as the main reference point. Legacy concepts may help explain where the product came from, but they should not drive a current Business Central training plan. Cloud releases, extensions, permissions, integrations, and Microsoft’s current documentation should shape what learners prioritise.

Another misstep is assuming that every business requirement should become a customisation. In Business Central, many requirements are better handled through configuration, dimensions, workflows, Power Platform integration, or a carefully scoped extension. Changing the base application is not the normal path for modern cloud-first Business Central work, and training should make that distinction clear early.

Teams also underestimate data setup quality. Posting groups, number series, dimensions, tax setup, item costing methods, and opening balances are not administrative details; they determine whether transactions post correctly and reports can be trusted. Poor setup can make a well-trained user look ineffective, while good setup makes processes easier to teach, support, and improve.

Measuring value after the classroom

The value of Business Central training should be visible in project behaviour. Learners should ask better questions during design workshops, test scenarios more thoroughly, and explain the operational effect of configuration decisions. Those outcomes are more meaningful than simply completing a class or passing through a menu sequence.

Useful measures depend on the organisation’s goals. A finance team may track whether the close process becomes easier to control, whether fewer manual spreadsheet adjustments are needed, or whether dimensions produce cleaner reporting. An operations team may look at stock variance, purchasing exceptions, order processing errors, or the time required to investigate costing differences. These measures do not guarantee a result, but they give training a connection to business performance.

There is also a governance benefit. When functional users understand the system well enough to test safely and describe requirements precisely, IT and implementation partners spend less time interpreting vague requests. Meanwhile, developers receive better specifications for AL extensions and integrations, which reduces the chance of building technical solutions around misunderstood business processes.

Building a training path that fits the project

A good Business Central training path starts with the role, not the course title. Process owners and functional consultants should prioritise configuration, financials, sales, purchasing, operations, testing, and MB-800-aligned skills. Developers should prioritise AL, extension architecture, APIs, source control, and deployment practices. Project sponsors and managers need enough understanding to make scope decisions and recognise when a request belongs in configuration rather than development.

The most effective next step is to connect learning to a live business scenario: a close process, an approval flow, an item costing issue, a purchasing cycle, or a reporting gap. From there, teams can choose training that supports the work they actually need to perform.
