Production Order
A production order is the binding instruction to manufacture a specific product in a defined quantity by a set date. It bundles the bill of materials, routing, material and capacity requirements into a single controllable process and is the central transactional record in the ERP system through which manufacturing is planned, released, confirmed and settled.
A production order is the binding instruction to manufacture a specific product in a defined quantity by a defined date. It answers the questions "What is being produced, how much, by when and with what?" and combines the required materials, the operations to be carried out and the scheduled capacities into a single, controllable process. This makes the production order – also called a manufacturing order, shop order or works order – the operational heart of every in-house production and, in the ERP system, the central transactional record of manufacturing.
Unlike master data such as the bill of materials and routing, which provide the permanent description of a product, the production order is a transactional record with a limited lifespan: it originates from a concrete requirement, runs through a status life cycle from creation through release to completion, and is archived after settlement. When the order is created, the ERP system copies the valid bill of materials and routing into it – so the order works with a snapshot that remains unaffected by later changes to the master data.
At a glance
- Binding order: one product, fixed quantity, fixed deadline
- Transactional record with a status life cycle: created → released → in progress → completion confirmed → settled
- Bundles the bill of materials (material) and routing (operations, capacity) into one process
- Originates from a sales order, an MRP run or a planned production proposal
- Provides actual data (shop floor data collection) for post-costing and inventory valuation
What belongs to a production order?
Like a document, the production order consists of a header and several line-item lists. The order header identifies the product to be manufactured via its item or material number, states the order quantity, start and end dates, priority, status and – in make-to-order production – the reference to the triggering sales order. Two central lists derive from this header: the material list from the bill of materials and the operations list from the routing.
The material list records which components are reserved and staged in what quantity for the order; the ERP system posts these requirements as a reservation against stock. The operations list describes the sequence of work steps, the designated work centers or machines, and the setup and unit times. Through these times the order occupies capacities and can be scheduled. In addition, the order often carries target costs from the pre-calculation, against which the actual costs are later posted.
The status life cycle of a production order
A production order runs through clearly separated states. First it is planned or created – often initially as a planned order without firm commitment. With release it becomes binding: material is reserved, capacity firmly scheduled, and the shop-floor paperwork or digital order documents are made available to the workshop. During processing the status changes to "in progress", and through shop floor data collection, confirmations of completed quantities, consumed material and time spent flow in. After completion confirmation, the product is posted to stock, the order is technically closed and finally settled commercially. Each status change triggers downstream postings in the ERP system.
How a production order arises and runs in the ERP system
A production order is rarely triggered manually. As a rule, material requirements planning (MRP) generates it: from sales orders, sales forecasts and reorder points it determines a net requirement for in-house parts and proposes production orders in a suitable quantity with a back-scheduled start date. Such a planned production proposal becomes a real order through conversion and release. Alternatively, it arises directly from a sales order (make-to-order) or is created stock-oriented for make-to-stock production.
After release, the order interlinks several modules. Inventory management reserves and issues components, capacity planning occupies work centers and reveals overloads, shop floor data collection captures confirmations from the workshop. On completion confirmation, the system posts the finished products to stock and closes the open requirements. The confirmed actual quantities and actual times then flow into post-costing: the comparison of target and actual costs reveals variances in material and time and, at the same time, provides the valuation-relevant cost of production for the inventory valuation of the finished goods.
Why the production order matters
The production order makes production plannable, controllable and traceable. It translates an abstract requirement into a concrete, scheduled work instruction and ensures that material and capacity are available on time. Without it, neither deadlines could be promised nor bottlenecks identified: only because each order ties up capacity and material can the ERP system make overloads visible and determine delivery dates realistically. This makes the production order the foundation for on-time delivery and supply capability.
Equally important is its role as a data collector. Through the confirmations, the order documents seamlessly which material and which times actually went into a product. This actual data is the basis for reliable post-costing, for the correct valuation of semi-finished and finished goods and – in regulated industries – for traceability via batch and serial numbers. A cleanly managed production order thus connects operational control with the commercial and the compliance-relevant view of production.
Distinction: production order, sales order and bill of materials
The production order is easily confused with neighboring terms. First of all, it must be clearly separated from the sales order: the latter is a sales document that establishes a delivery obligation towards a customer. The production order, by contrast, is an internal production document that organizes manufacturing. A sales order can trigger a production order, but need not – for example when delivery is made from stock. In make-to-order production the two are linked via a reference chain.
Production order vs. bill of materials and routing
The bill of materials and routing are master data: they describe in general terms from which material and through which operations a product is created – independent of a specific production lot. The production order is the application of this master data to a single case: it copies the bill of materials and routing at the time of creation into itself, multiplies the quantities by the order quantity and thereby becomes a production- and quantity-related transactional record. Changes to the bill of materials therefore only affect future orders, not retroactively those already released.
Production order vs. purchase order and service order
While the production order controls in-house production, the purchase order in purchasing covers external procurement: both fulfill a requirement, but one internally through production, the other externally through procurement. The service order, in turn, organizes services and repairs instead of manufacturing new products. For each part, material requirements planning decides, based on the procurement type, whether a requirement leads to a production order or a purchase order.
DACH specifics: GoBD, valuation and traceability
In the DACH region, the production order directly touches tax and legal requirements. From the confirmed actual costs derive the cost of production and thus the inventory valuation of the semi-finished and finished goods, which feed into the commercial and tax balance sheets. Because valuation-relevant postings arise from this, the confirmations and cost postings of a production order must be recorded in an unalterable, traceable and reproducible manner in the sense of the GoBD. The order thereby becomes a building block of an audit-proof document trail.
Added to this are industry-specific traceability requirements. In food, pharmaceutical and medical technology operations, the production order links the installed batches and serial numbers of the components with the batch of the product, so that in the event of a recall the complete material path can be reconstructed. Whether an operation gets by with the ERP system's production control for this or supplements it with a specialized MES depends on the depth of manufacturing and the degree of regulation – but the commercial management of the production order remains the task of the ERP system.
Example
Example: furniture workshop produces a batch order for 40 shelves
A mid-sized furniture workshop receives orders for the "Nord 80" shelf via its online shop and specialist retailers. The nightly MRP run nets the open sales orders against stock and proposes a production order for 40 units with completion in twelve days. The production manager releases the proposal; the ERP system copies the bill of materials – solid wood panels, fittings, screws, packaging – and the routing with the operations cutting, edge processing, drilling and assembly into the order, reserves the material and schedules the sawmill and assembly stations.
In the workshop, employees confirm the completed quantities and times per operation via shop floor data collection; material consumption is posted out at cutting. After completion confirmation, the system posts 40 shelves into the finished goods warehouse and makes them available for shipping. The post-costing then shows that wood consumption was three percent above the pre-calculation – a sign of too tightly calculated waste, which the workshop corrects in the product's bill of materials for future orders.
