An assembly item is an inventory item made of several components, but identified as a single item. This type of item lets you define the members of an assembly and to separately track both the component items and the assembled items in inventory. For each assembly build, the assembly item stock level increases and the member items’ individual stock levels decrease.
An assembly build transaction records the physical manufacture of an assembly item from component items and the related inventory level changes.
An assembly unbuild transaction records the physical taking apart of an assembly item back into its component items and the related inventory level changes. For each assembly unbuild, the assembly item stock level decreases and the member items’ individual stock levels increase.
