BOM line types
Supply Chain Management offers various BOM line types:
Item - Select the Item line type for materials or services that are directly consumed and that don't require further explosion or pegged supply.
Pegged supply - Select the Pegged supply line type when you want to create a sub production, a BOM line event kanban, or a direct purchase order for any product variant that the BOM line references. The sub production, event kanban, or purchase order is created when you estimate the production order. The required item quantities are automatically reserved for the consuming production order.
Phantom - Select the Phantom line type when you want to explode any lower-level BOM items that are contained on the BOM line. When using BOM lines of the Phantom type, the parent BOM line that refers to a product variant that has a phantom BOM is replaced by the component items that are listed as BOM lines in that BOM. This is determined by the applicable active BOM version of that product variant. If the product variant has an applicable active route, the operations of that route are merged into the parent route.
Note that phantoms are typically used to simplify the engineering process. Extensive use of phantom BOMs in many levels influences performance, especially in highly repetitive manufacturing scenarios. To improve performance, you should avoid deep hierarchies of phantoms. Instead, use pre-exploded production BOMs and routes.
Vendor - Select the Vendor line type if the production process uses a subcontractor and you want a sub production or purchase order to be created automatically for the subcontractor.
