Setup in Odoo

1. Go to Developer Mode (activate it if not already).
2. Navigate to Technical > Automation > Automated Actions.
3. Create a new Automated Action:
   • Model: Manufacturing Order (mrp.production)
   • Trigger: On Update or On Creation & Update (depending on use case)
   • Filter Domain (optional): You may filter on state = 'confirmed' or similar.
   • Action To Do: Execute Python Code

Python Code Example

Here’s the Python code that can be used in the automated action to prevent production if components are missing:

if record.state == 'confirmed':
    for move in record.move_raw_ids:
        if move.product_id.type == 'product' and move.product_uom_qty > move.reserved_availability:
            raise UserError(f"Not enough stock for component '{move.product_id.display_name}'.\n"
                            f"Required: {move.product_uom_qty}, Reserved: {move.reserved_availability}")
