what is meant by bom and what is the difference between bom and super bom?
Hi Friend,
BOM is the bill of material .Sales BOM
A bill of material (BOM) describes the different components that together create a product. A BOM for a bicycle, for example, consists of all the parts that make up the bicycle: the frame, the saddle, wheels, and so on.
When you enter the material number of a bill of materials that is relevant for sales order processing, the system displays the material that describes the whole bill of materials as a main item. The individual components are displayed as lower-level items.
There are two ways to process a bill of materials in Sales. Once you have entered a bill of material in a sales order, the system runs pricing, inventory control, and delivery processing at: Main item level if the material is assembled, or - Component level if the material is not assembled.
*Processing at Main Item Level (ERLA)*
If you want the system to carry out pricing, inventory control, and delivery processing at main item level, enter ERLA in the Item category group field of the Sales: sales org. 2 screen in the material master record of the finished product. This means that the components only function as text items and are not relevant for delivery.
Processing at Component Level (LUMF)
If you want the system to carry out pricing, inventory control, and delivery processing at the component level, enter LUMF in the Item category group field of the Sales: sales org. 2 screen in the material master record of the finished product. In this case, only the components are relevant for delivery. During processing the system automatically creates a delivery group. The latest delivery date among all the components becomes the delivery date for the entire delivery group
Purpose:
· The purpose of this activity is to create bills of material (BOMs) for the configurable material which is known as super BOM
· Super BOM comprise all the variant as well as non-variant parts required for producing configurable material.
Procedure
1. Access the activity using one of the following navigation options:
SAP Menu Logistics ® Production ® Master Data ® Bills of Material ® Bill of Material ® Material BOM ® Create
Transaction Code CS01
· The Create Material BOM: initial screen appears. On this screen, data that identifies the bill of material are maintained as well effectivity data.
· In the Material field, the configurable material for which super BOM need to create is entered.
· Plant and BOM usage is entered. In general BOM usage 1 for production and 3 is for Universal.
· In Component screen list of variant and non-variant parts are entered along with that quantity is entered based on Base qty. of the configurable material.
· It is also possible to enter a class as a BOM component with item category class Item. This class must hold all characteristics and also classified with each material.
· Class type 200 and 300 can be used as a class item.
Following Procedure is followed for assigning class with BOM as a class Item.
· Enter the item category for class items in BOM.
· Make entries in the fields that identify the class
Class types
Class
· Enter the quantity.
Enter a unit of measure if appropriate.
The system determines the unit of measure from the additional data of the class.
If a unit of measure without a dimension is maintained in the additional data of the class, you cannot change this unit

Dear Ramanna
1) BOM
The list of components that make up a system. For example, a bill of materials for a house would include the cement block, lumber, shingles, doors, windows, plumbing, electric, heating and so on. Each subassembly also contains a bill of materials; the heating system is made up of the furnace, ducts, etc. A bill of materials "implosion" links component pieces to a major assembly, while a bill of materials "explosion" breaks apart each assembly or subassembly into its component parts.
2) Super BOMs
The bill of material (BOM) of a configurable material contains all the components that are required to manufacture the material. The BOM contains components that are only used in specific variants (variant parts), as well as components that are used in all variants (non-variable parts).
This is why BOMs for configurable materials are known as super BOMs
Thanks

hi,
BOM is Bill of Material.
eg Computer
computer has CPU, Monitor etc so these are components which make a Finished good material.
Super BOM is th one where the product is possible to produce with different features by combining variouscomponents available in BOM ie Variant configuration in SAP.
eg of this is car with different coloursetc
Hope ur clear with the above.
Dont forget to reward points.
Regs,

Further super bom is special kind of bom where you have more than one option available for any one component or all components of the bom.
