The system manages one other kind of work order that is not represented by a separate type code. Subassemblies can be set up so that work orders are automatically created for them when a parent item is allocated or released using:
• Work Order Release/Print (16.6; 16.30 for enhanced .NET UI version)
• Multiple Work Order Release/Print (16.7) 
To do this, set the Pur/Mfg code for the item to Routable in Item Master Maintenance (1.4.1) or Item Planning Maintenance (1.4.7). A work order for a routable item has the same number as the parent work order, but a unique work order ID.
These work orders can be allocated, released, and used for processing component issues, inventory receipts, and shop floor control transactions. When the subassembly is finished:
• Process a work order receipt from the routable work order.
• Then issue the subassembly as a component to the parent work order.
