BOM:Bill of material

It contains the list of materials included to produce the final product.

it is been created in the tcode CS01

It is mainly used during Subcontracting.

where we issue purchase order for the final product thts is the BOM and supply the raw material to produce the final product.

there are two types of BOM multi level and single level

We all know, Computer is the combination of " Monitor, CPU , Keyboard, Mouse"

Here CPU consists, Hard disk,motherboards ,Processor, Ram etc..,

Computer is the Main item

Monitor,CPU,keyboard, Mouse are all sub items for Main item.

Sub item CPU again contains Items.

This kind of material is known as Multi BOM,

Simply, BOM with in the BOM is Multi BOM.

If you want configuration this into SAP,

First you need to create in MM01 Computer as Main Item-

(item category group- ERLA, if you want to give price on material Level).

Create in MM01, Monitor,CPU,keyboard,Mouse,Hard disk,motherboards,Processor,Ram

as sub items

( Item cat group- NORM,but for CPU Item cat group- ERLA)

Now Create BOM, CS01- Computer Include Monitor,CPU,keyboard,Mouse as sub items,

again create BOM,CS01- CPU include Mouse,Hard disk,motherboards,Processor,Ram as sub items for CPU mainitem.

In Configuration of Item Category VOV7 Change the Structure scope from "A - explode single level BOM" to "B - Explode Multi Level BOM" for Item Cat: TAQ & TAP.

Create Sales order for Main item Computer :

All the items will be displayed as sub items include mouse,Hard disk,Mother Board,Processor,Ram.

Item category determination in Multilevel BOM

If u want to price the main item then

OR ERLA -

TAQ

OR NORM -

TAQ TAQ1

OR NORM -

TAQ1 TAE

In TAQ item category functionality in the Structure Scope field Select ' B' .

TAQ1 is copy of TAQ but only difference is in the Structure Scope field Select "A".

TAE is standard one.

If u want to price the components then

OR LUMF -

TAP

OR NORM -

TAP TAP1

OR NORM -

TAP1 TAN

In TAP functionality in structure scope field select "B".

TAP1 is copy of TAP but in Structure scope field select "A".

In that way BOM item category is determined for multilevel BOM during sale order process

1. BOM is bill of material.

2.. Sub contract process we used bom(bill of material).

3.Three types of bom in sap

Example.

header materail(finished product, like pen),

How will u make the product pen?

u will give to some raw material to subcontract vendor( that mat is called bom)

Tcode for create bom :cs01

create po with L item cat. u can expolde ur bom

Bills of Materials in Sales Documents

Implementation Considerations

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.

Process Flow

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

The type of processing used by the system is determined by the item category group that you enter in the material master record for relevant materials.

Processing at Main Item Level

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. The following graphic shows how a bill of material is processed at main item level.

Processing at Component Level

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.

For more information about how to create and maintain bills of material, see PP - Bills of Material documentation in the R/3 library.

HI,

Bills of material are best used when there are components that are relevant. They CAN be used for things like you mention here but I am not sure that it will help your business requirements.

I would suggest that you consider adding the charge as a new pricing condition.

That way the total cost of the item will be the price plus the disposal charge. If you use a separate line on the PO the cost of the disposal will not be connected to the cost of the bulb and so when you issue any they will use the cost without the disposal charge.

SO I would create an info record and enter the details of the price and then add in a surcharge condition type (for the disposal cost).

That ay whenever you order these bulbs from this vendor, the system will propose the cost including the disposal cost.

Production Versions are used to describe the production process to be used for planned / production order.

Why is it required?

Suppose you have 2/3 production lines and 2/3 alternative BOMs to produce one Finished Goods.

How system will come to know which BOM and Routing to be used. This is done thru Prod.Version.

In production version we maintain the combination of BOM and routing.

Also it can be designed with lot size or validity period.

Go to MM02--->MRP4 / Work scheduling view -

> Prod.Version.

Enter the validity period and lot size. and the production version should be unlocked.

After entering the reqd. routing no. and BOM alternative , carry a check.

After getting the Green signals ,Continue.

Thus you have saved the prod. version.

Mass processing TCode- C223.

T.code c223, enter the material and plant

Enter the prod. version number for identification

Enter the validity date rage of this version

Enter the lfrom ot size and To lot size range

Enter your task list type and group and group counter

Enter which alternative bom you are going to assign and bom usage.

Click the consistency check button. If it comes green, you have created correctly. otherwise check your error

and also there is bapi

use BAPI_MATERIAL_BOM_GROUP_CREATE fm which will create a BOM for a material.

Please try these FM.

CSAP_ORD_BOM_CREATE

CSAP_ORD_BOM_DELETE

CSAP_ORD_BOM_ITEM_SELECT

CSAP_ORD_BOM_MAINTAIN

Bill of Material or BOM is nothing but the list of items that go into making the main item. E.g to build a caomputer at high level u would need mouse,keyboard,monitor and CPU so these become BOM for making computer. This is mainly used in production.

The link to Bill of Material is as follows..

Execute CS01

enter - material(e.g: X) for which BOM has to be created

- Plant

- BOM usage, normally production

Press enter

General item Overview

enter the components and their qty required to produce X
