Workflow: Manufacturing Order

Modules involved: Manufacturing (MRP) · Warehouse · Purchase
Who uses it: Production planner, Workshop operator, Production manager, Warehouse keeper
Typical duration: Hours – weeks (depends on product complexity)

Overview

The complete manufacturing workflow: from the need for a finished product (triggered by a sales order or internal planning) to the finished product entering the warehouse. Includes checking material availability, scheduling operations on work centers, tracking execution, and integration with purchasing (if materials are missing).

Step by step

1. Bill of Materials (BoM) — Product structure

Where: /admin/manufacturing/bill_of_material_manage

What a BoM defines:

The finished product + quantity produced per run
Components (raw materials, subassemblies): product, quantity, unit of measure
Associated routing: the sequence of operations

BoM fields (mrp_bill_of_materials):

Field	Notes
`bom_code`	Unique BoM code
`product_id`	Finished product
`product_qty`	Quantity produced per BoM run
`routing_id`	Routing (operations + work centers)
`consumption`	Consumption mode: `automatic`, `manual`, `semi-automatic`
`ready_to_produce`	Flag that the BoM is validated and ready for use

BoM details — components (mrp_bill_of_material_details):

Field	Notes
`product_id`	Component (raw material / subassembly)
`product_qty`	Quantity required per run
`unit_id`	Unit of measure
`operation_id`	Which operation consumes this component

A BoM can be reused for any number of manufacturing orders. Changes to a BoM are recorded in mrp_bom_changes_logs with the type of change and the operator.

2. Routing — The production plan

Where: /admin/manufacturing/routing_manage

What a routing defines:

The sequence of operations (cutting, welding, assembly, quality control)
The work center for each operation
Estimated duration per operation
Whether the next operation can start before the current one is finished (start_next_operation)

Work centers (mrp_work_centers):

Field	Notes
`work_center_code`	Unique code
`working_hours`	Working schedule (shifts)
`time_efficiency`	Efficiency (%) — adjusts planned durations
`capacity`	Simultaneous capacity (how many orders can run in parallel)
`oee_target`	OEE target (Overall Equipment Effectiveness)
`costs_hour`	Cost per hour — used in MO cost calculation

Working schedule (mrp_working_hours):
Shifts defined by days of the week (work_from, work_to), with time-off periods (holidays, maintenance), for realistic time planning.

3. Manufacturing Order (MO) — Execution

Where: /admin/manufacturing/manufacturing_order_manage

Creation:

From a sales order: Create Manufacturing Order button on the confirmed order
Manually: define the product, quantity, BoM, warehouses

Key MO fields:

Field	Notes
`manufacturing_order_code`	Unique code (prefix + auto-increment)
`product_id` + `product_qty`	What and how much is produced
`bom_id`	BoM used
`routing_id`	Routing
`date_deadline`	Delivery deadline
`date_planned_start`	Planned production start date
`components_warehouse_id`	Warehouse from which materials are consumed
`finished_products_warehouse_id`	Warehouse where the finished product enters
`purchase_request_id`	Link to purchase request if materials are missing

Manufacturing order statuses:

Status	Description	What happens
`draft`	Created, unconfirmed	Can be freely edited
`confirmed`	BoM and routing validated	Material availability is checked
`planned`	Production schedule generated	Work Orders are created; materials reserved
`in_progress`	Production has started	Operators record activity on WOs
`done`	Completed	Finished product entered warehouse; materials consumed
`cancelled`	Cancelled	Reserved materials are released

4. Material verification — Availability and purchasing

When the MO transitions to confirmed:

System checks qty_reserved vs available stock in components_warehouse_id
If materials available: reserved immediately (qty_reserved increased on components)
If materials insufficient: the material_availability_status field marks the shortage + optionally a Purchase Request is automatically created (purchase_request_id filled in on MO)

Material reservation (mrp_manufacturing_order_details):

Field	Description
`product_id`	Component
`qty_to_consume`	Required quantity (from BoM × MO quantity)
`qty_reserved`	Quantity blocked from stock
`qty_done`	Quantity actually consumed
`warehouse_id`	Source warehouse

5. Work Orders — Shop floor execution

Where: /admin/manufacturing/work_order_manage

Creation:
When the MO transitions to planned, the system automatically creates one Work Order for each operation in the routing.

Work Order fields:

Field	Notes
`manufacturing_order_id`	Parent MO
`routing_detail_id`	Operation from the routing
`work_center_id`	Allocated work center
`operation_name`	Operation name
`qty_production`	Quantity to produce
`qty_producing`	Currently in progress
`qty_produced`	Completed
`date_planned_start/finished`	Planned schedule
`date_start/finished`	Actual dates
`duration_expected`	Planned duration (minutes)
`real_duration`	Actual duration

Work Order statuses:

Status	Description
`waiting`	Waiting for previous WO to finish (if `start_next_operation = false`)
`ready`	Can start — resources are available
`in_progress`	Operator is working
`finished`	Operation complete

Time recording (mrp_work_order_time_trackings):

Operator starts/stops the timer on the WO:

from_date, to_date → calculates duration
staff_id → responsible operator
Sum of actual times → real_duration on WO vs duration_expected from planning

6. Material consumption and finished products — Production output

Material consumption:

On completion of each WO or when closing the MO: qty_done updated on components
Stock in components_warehouse_id automatically deducted
Discrepancies from the BoM recorded in mrp_bom_changes_logs

Consumption mode (consumption):

Mode	Description
`automatic`	Materials consumed automatically when WO is validated
`manual`	Operator enters the consumed quantities
`semi-automatic`	System proposes; operator confirms

When MO status → done:

Finished product (quantity product_qty) → added to finished_products_warehouse_id
Stock transaction created in the Warehouse module (goods_transaction_detail)
MO cost calculated: materials + hours × cost_hour of work centers
Remaining reserved materials are released

What is created automatically

Event	Created automatically
MO → `confirmed`	Stock check; material reservation (`qty_reserved`)
Insufficient materials	Purchase Request (`purchase_request_id` on MO)
MO → `planned`	Work Orders per operation from routing
WO timer started	Entry in `mrp_work_order_time_trackings`
MO → `done`	Finished product added to warehouse; stock transaction; cost calculated
BoM modified on active MO	Log in `mrp_bom_changes_logs`

Points where the workflow may stall

Problem	Likely cause	Solution
MO cannot transition to `planned`	Incomplete BoM or missing routing	Check BoM → all components have valid `product_id` + `unit_id`; add routing
Materials reserved but stock still decreases	Another MO or delivery consuming from the same stock	Check `qty_reserved` vs actual available stock; adjust MO priority
WO remains `waiting`	Previous WO not finished	Complete WOs in order; or enable `start_next_operation` on the previous operation
Finished product does not appear in warehouse	MO has not transitioned to `done`	Complete all WOs; mark MO as `done`
MO cost is 0	`costs_hour` = 0 on work centers	Configure cost per hour on each Work Center
Purchase request not generated	Feature not enabled or materials at 0 without being checked	Enable Purchase integration from Manufacturing settings

Before the first Manufacturing Order, the following must be configured:

Units of measure — /admin/manufacturing/setting → Units
Work centers — /admin/manufacturing/work_center_manage — including schedule and cost/hour
Working schedules — shifts + days off
Routings — /admin/manufacturing/routing_manage
BoM for each product — /admin/manufacturing/bill_of_material_manage
Prefixes — MO, BoM, Routing codes from /admin/manufacturing/setting
