Rules for Bills Of Material

• Before you can set up a bill of material, you must add item records for the items you intend to use for the master item and component items in the bill of material.

• Before you can post an assembly transaction, the master item and all its component items must be stocked at the same Inventory Control location.

• Master items and component items can use any costing method except the user-specified costing method.

• You cannot delete an item from inventory if it is a master or component item in a bill of material.

• The component items in a bill of material are fixed (you cannot use alternative components). To build a master item using an alternative component item, you must create, and use, a separate bill of material.

• You can create multilevel bills of material that include master items of subassemblies as component items.
