-A bill of materials or product structure (sometimes bill of material, BOM or associated list) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts and the quantities of each needed to manufacture an end product. A BOM may be used for communication between manufacturing partners, or confined to a single manufacturing plant. -A bill of materials is often tied to a production order whose issuance may generate reservations for components in the bill of materials that are in stock and requisitions for components that are not in stock. -BOMs are of hierarchical nature, with the top level representing the finished product which may be a sub-assembly or a completed item. BOMs that describe the sub-assemblies are referred to as modular BOMs. An example of this is the NAAMS BOM that is used in the automotive industry to list all the components in an assembly line. The structure of the NAAMS BOM is System, Line, Tool, Unit and Detail.

A Bill of Materials is a list of constituent items along with quantity details that can be allotted for the manufacture of acertain product,by-product or likewise. This facilitates immediate reduction in stock of the item automatically. This process of listing the items that make up another item is made possible in Tally by enabling the Bill of Materials Facility.

**BILL OF MATERIAL** When a specific type of product is to be produced. Then production department involved in such production requests purchase department for purchase of material for that product. In such case a document which shows complete list of all materials and & components,parts required for a particular job including small items like nuts, bolts screws etc is called as bill of material. So based on it, any production department sends purchase requisition to purchase department. Thanks

Hi Bill of materials is a schedule of standard quantities of materials required for any job or other unit of production.A comprehensive Bill of material should rigidly lay down the exact description and specifications of a materials required for a job or other unit of production and also required quantities so that if there is any deviation form the standard list, it can be easily detected. The bill of material is prepared by the Engineering or Planning Department. The number of copies vary but 4 id minimum A copy of it is usually sent to 1. Stores department 2. Cost Accounts Department 3. Production Control departmetn 4. Engineering Department

Hii Uma **Bill Of Material** A Bill of Materials is a list of constituent items along with quantity details that can be allotted for the manufacture of acertain product,by-product or likewise. This facilitates immediate reduction in stock of the item automatically. This process of listing the items that make up another item is made possible in Tally by enabling the Bill of Materials Facility. Bill of Material (BoM) is created only for those items that are being assembled in-house.Therefore, you need to specify a BoM at the time of creating a Stock Item or while altering the stock item. For trading items, you do not need a BoM. How to create BOM with tally- Let us create a new Stock Item PEN and specify BoM- Gateway of Tally ~> Inventory info ~> Stock Items ~> Create ~> F12 ~> All Component list detail (BOM) - YES Thnaks

Simply saying it is recipe for the food. In Manufacturing the same recipe is called Bill of Materials. BOM Consists of Raw Materials, Components (Boughtout Items), Assemblies and sub assemblies (again it has a sub bill of Materials) the Top most component is called Final or End product. For example : ![Bill of Material for Bi-Cycle]

Hiiiii friend.... DEFINITION of 'Bill Of Materials - BOM' --------------------------------------- A comprehensive list of raw materials, components and assemblies required to build or manufacture a product. A bill of materials (BOM) is usually in a hierarchical format, with the topmost level showing the end product, and the bottom level displaying individual components and materials. **Regards,**
