Set up an assembly bill of material
An assembly BOM is the master data that defines which component items go into an assembled end item and which resources are used to assemble that assembly item. When you enter an assembly item and a quantity in the header of a new assembly order, then the assembly order lines are automatically filled according to the assembly BOM. There is one assembly order line per component or resource.
To define a parent item that consists of other items, and potentially of resources required to put the parent together, you must create an assembly BOM. Assembly BOMs usually contain items, but also can contain one or more resources that are required to put the assembly item together.
Assembly BOMs can have multiple levels, which means that a component on the assembly BOM can be an assembly item itself. In that case, the Assembly BOM field on the assembly BOM line contains Yes.
