| An assembly item is an item with default source Assembly. You specify an item's default source in the Default Supply Source field in the Items - General (tcibd0501m000) session. Restrictions The following rules and restrictions apply to assembly items: An item cannot be both a revision-controlled item and an assembly item. An assembly item must be a serialized item. An item with item type Engineering Module is always an assembly item. A project item cannot be an assembly item. An assembly item cannot be used as subassembly for subcontracting. Item types Generic and Manufactured To support storing an assembly item in inventory, you can represent one physical item by a pair of two items in ERP LN: An item with item type Generic. You use this item code on the assembly order in Assembly Control. An item with item type Manufactured. You can use this item code on sales order lines and on warehousing orders and to record item inventory. If you deliver the finished generic item to the customer without storing it in inventory, you do not need an item with item type Manufactured. Alternatively, you can configure product variants that contain purchased configurable items. You can use a configurable item to create a item structure that can hold a configurable purchased sub-assembly. You can store the end item in Warehousing and perform inventory transactions. For more information on procuring purchased configurable items in Assembly Control module, refer to Procuring configured items in Assembly Control - Master Data Setup Procuring configured items in Assembly Control - BOM setup Product variants - Purchased configurable items Assembly items and FAS items A FAS item is a generic item or a manufactured item with the FAS (Final Assembly Scheduling) order system. FAS items are produced in a mixed model flow process on an assembly line. If you set the Default Supply Source field in the Items - General (tcibd0501m000) details session to Assembly, ERP LN automatically sets the Order System field in the Items - Ordering (tcibd2500m000) session to FAS. You can also specify the order system by warehouse-item combination in the Warehouse - Item (whwmd2510m000) session. An assembly item must have order system FAS.
