Assembly items

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 (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, Manufactured and Product

To support storing an assembly item in inventory, you can represent one physical item by a pair of two items in 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 or Product

You can use this item code on sales order lines and on warehousing orders to record item inventory.

Note: 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 or Product.

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

Product variants - Purchased configurable items

Assembly items and FAS items

A FAS item is a Generic, Manufactured or Product 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 (tcibd0501m000) details session to Assembly, LN automatically sets the Order System field in the Items (tcibd0501m000) session to FAS. You can also specify the order system by warehouse-item combination in the Item Data by Warehouse (whwmd2510m000) session.

An assembly item must have order system FAS.
