Manufacturing in Business Central: The Complete Guide

Manufacturing is the biggest and most connected part of Business Central. It touches items, inventory, warehouse, purchasing, sales and finance all at once, which is exactly why it feels overwhelming when you first open it. Where do you start? What has to be set up before what? And which of the many screens actually matter day to day?

This guide is the map. It explains how the whole module fits together in plain English, walks you through the four stages of the manufacturing lifecycle, and links to a detailed guide for every single step. Whether you are setting up manufacturing for the first time, training a team, or just trying to understand where one screen fits in the bigger picture, start here and follow the links that apply to you.

What Manufacturing in Business Central Covers

The manufacturing module answers one question: how do you turn raw materials into finished goods, and know what it cost you? To do that, Business Central needs to know three things about every product you make:

• What goes into it. That is the production BOM, the list of components and quantities. Think of it as the recipe.
• How it gets made. That is the routing, the sequence of operations and which resources perform them.
• Where the work happens. Those are your work centers and optional machine centers, with calendars defining their available capacity.

Once that master data exists, a production order brings it all together. Business Central copies the BOM and routing onto the order, schedules the operations against your capacity, and then records what you actually consumed and produced. Those postings update inventory and the general ledger in real time, which is how you get true product costs rather than estimates.

Licensing: Premium vs Essentials

This catches people out during buying decisions, so it is worth stating plainly. The full manufacturing module, meaning production orders, production BOMs, routings, work and machine centers and capacity planning, requires a Business Central Premium licence.

The lighter Assembly functionality is included in Essentials. Assembly handles kitting and simple builds: an assembly BOM and an assembly order, but no routing, no work centers and no capacity planning. For many businesses that combine or kit products rather than truly manufacture them, Assembly on Essentials is genuinely enough.

The Four Stages of the Manufacturing Lifecycle

Every manufacturing setup, in every company I have worked with, follows the same four stages. Understanding this order is the fastest way to make sense of the module, because it also tells you what to set up first.

The rest of this guide follows those four stages in order, with links to a detailed walkthrough of every step.

Stage 1: Master Data

This is the foundation, and where most of your setup time goes. There are four groups of master data to build, and a sensible order to build them in.

a) Items and Stockkeeping Units

Everything starts with the item. Your components, your subassemblies and your finished goods are all items, and their setup (costing method, replenishment system, reordering policy) drives how manufacturing behaves later.

• Stockkeeping Unit (SKU) in Business Central Explained
• Stockkeeping Units Setup
• Item Picture Upload and Download

Stockkeeping units matter as soon as you run more than one location or variant, because they let you set different replenishment and reordering rules per location rather than one rule for the whole company.

b) Production BOMs

The BOM is your recipe. Get it right and costing and planning both work; get it wrong and nothing downstream can be trusted. Note that certifying a BOM is optional while you are still designing, but you should certify it before real use.

• How to Upload or Download a BOM (Bill of Materials)

💡 Tip: Use BOM versions rather than editing a certified BOM in place. Versions keep your history intact, which you will be grateful for the first time someone asks why last quarter’s cost was different.

c) Routings

The routing defines the sequence of operations, which work center or machine center performs each one, and how long each takes (setup time, run time, and the non-productive wait, move and queue times). Attach both the BOM and the routing to the item card, and the item is ready to manufacture.

• Create a Routing: Step by Step Setup Guide
• Routing Links Explained

Routing links deserve a mention here because they are widely ignored and genuinely useful: they tie specific BOM components to specific routing operations, so materials are consumed at the operation that actually uses them rather than all at the start.

d) Work Centers, Machine Centers and Calendars

These are your production resources: where the work physically happens and how much capacity is available. The hierarchy is work center group, then work center, then optional machine center.

• Work Center vs Machine Center: And When to Use Each (start here)
• How to Set Up a Work Center
• How to Set Up a Work Center Calendar

The most common mistake at this stage is adding machine centers before you need them. Most manufacturers do well with work centers only, using the Capacity field to represent several machines or people. Add machine centers only when you must plan or cost individual machines separately.

Stage 2: Planning

With master data in place, planning works out what you need to make and buy, and when. Business Central’s planning engine reads demand (sales orders, forecasts, existing orders) against supply (inventory, incoming purchases) and produces suggestions.

The normal flow is: run the planning engine, review the suggestions in the planning worksheet, adjust quantities or dates where your judgement differs, then carry out the action messages to create real orders. That human review step matters. Planning suggests, people decide.

• MRP vs MPS: What Is the Difference in Business Central?

The short version of that difference: MPS plans your finished, independently demanded items at the top level, while MRP works down the BOM levels to plan the components needed to support that schedule.

Stage 3: Execution

Execution is where the shop floor gets involved. A production order moves through statuses as it progresses, and Business Central has five order types:

Two things happen while an order is released: consumption (components leave inventory) and output (finished goods enter inventory, and operation time is recorded). Depending on your flushing method these can post automatically or be entered manually.

• Refresh a Production Order
• Finished Goods Item Tracking (Lot and Serial Numbers)

The Refresh function is worth understanding early: it recalculates component and routing lines from the master data after you change the order header. Useful, but remember it discards manual line changes, so refresh before you fine tune, not after.

When components run out: substitution

Real production rarely goes perfectly. When a component is unavailable, item substitution lets you swap in an alternative without rebuilding the order.

• Item Substitution in Business Central
• Substitute an Item in a Production Order

When someone else does the work: subcontracting

If an operation is performed by an outside vendor, subcontracting handles it. You create a work center linked to a vendor, and the subcontracting worksheet turns production operations into purchase orders automatically.

• Subcontracting Step by Step Process
• Subcontracting Process in Dynamics NAV (India Localization)
• Subcontracting Posting Error and Fix

Light assembly instead of full production

Not everything needs a routing and work centers. If you combine components into a kit, assembly is simpler and faster.

• How You Gather Components for Assembly Depends on Your Setup

Stage 4: Costing and Closing

Manufacturing costing is where finance and production meet, and where a badly set up system shows itself. When you finish a production order, Business Central reconciles work in progress and settles the actual cost of what you made.

The place to look is the Production Order Statistics page, which shows expected against actual cost broken down by material, capacity and overhead. Variances there are not errors; they are information. A consistent material variance usually means your BOM quantities are wrong. A consistent capacity variance usually means your routing times are wrong.

• Unit Cost Calculation for Manufactured Items

One related setting worth knowing about: Automatic Cost Adjustment. Setting it to Always makes cost adjustment run during every posting, which is a common cause of table locking in busy systems. If you see lock errors during posting, see Business Central Table Locked by Another User: Causes and Fixes.

Assembly vs Manufacturing: Which Do You Need?

Because this decision affects your licence cost, it is worth being clear:

If you never need to schedule machine time or cost labour by operation, assembly is very likely enough.

Where to Start (Learning Paths by Role)

Twenty five guides is a lot. Here is the order I would actually recommend, depending on who you are.

If you are implementing manufacturing for the first time

Follow the four stages in order. Start with the item card, then production BOMs, then routings, then work centers versus machine centers and work center setup. Only then look at planning and production orders.

If you are a production planner

Start with MRP vs MPS, then work center capacity and load, then refreshing production orders.

If you work in finance

Go straight to unit cost calculation, then read the costing stage above on variances, then production BOMs, since BOM accuracy is what drives your material costs.

FAQ, Manufacturing in Business Central

What does the manufacturing module in Business Central do?

It turns raw materials into finished goods and tracks what that cost. You define what goes into a product (production BOM), how it is made (routing), and where the work happens (work centers). Production orders then bring those together, and posting consumption and output updates inventory and the general ledger.

Do I need a Premium licence for manufacturing?

Yes. Full manufacturing (production orders, production BOMs, routings, work and machine centers, capacity planning) requires Business Central Premium. The lighter Assembly functionality is included in Essentials. Confirm current licensing terms with your partner, as they change.

What is the difference between assembly and manufacturing?

Assembly combines components into a finished item in one step, with no routing, work centers or capacity planning. Manufacturing adds the routing (operation sequence), production resources and capacity scheduling. Assembly suits kitting; manufacturing suits real production with machine time.

In what order should I set up manufacturing?

Items first, then production BOMs, then routings, then work centers, machine centers and calendars. Only once that master data is right should you move on to planning and production orders. Rushing master data is the most common cause of failed implementations.

What are the five production order types?

Simulated (test a scenario), Planned (created by planning, re-planned each run), Firm Planned (a commitment that planning will not overwrite), Released (live on the shop floor, where you post consumption and output), and Finished (closed, with WIP reconciled).

What is the difference between MRP and MPS?

MPS plans finished, independently demanded items at the top level. MRP works down the BOM levels to plan the components needed to support that schedule. Most companies use both together.

Does this guide apply to Dynamics NAV as well?

Largely yes. The manufacturing logic is effectively the same from NAV 2013 onward. What differs is navigation: NAV uses menu paths such as Manufacturing, Capacities, Work Centers, while Business Central uses the search box. A few localizations, such as the old India subcontracting module, exist only in NAV.

Why does my production order cost differ from what I expected?

Because expected cost comes from your BOM and routing, while actual cost comes from what was really consumed and recorded. Review the Production Order Statistics page. Consistent material variances usually mean BOM quantities are wrong; consistent capacity variances usually mean routing times are wrong.

Final Thoughts

Manufacturing in Business Central looks intimidating because it is large, not because it is complicated. Once you see it as four stages, master data, planning, execution and costing, every screen has an obvious place in the sequence, and you know what has to exist before what.

If you take one thing from this guide, make it this: invest in master data. Accurate BOMs, realistic routing times and honest work center capacity are what make every downstream number trustworthy. Get those right and planning, scheduling and costing all follow. Get them wrong and no amount of clever configuration will save you.
