Technical types of BOM

Hi ALL,
What are the technical types of BOM?...How do we maintain it?
Thanks
Regards,
Ameya K.

Dear Amyea,
Please check the following taken from SAP help.
Technical Types
When you first create a BOM for a material, the system automatically creates the first alternative. The technical type of the BOM is not yet defined, so the technical type is " " (blank). The following graphic shows the structure of a "simple" BOM.
Some companies produce many similar products that have a lot of common parts. To reduce the workload for creating BOMs, you can extend a simple BOM to create a composite BOM, known as a "BOM group".
Which Technical Types Exist?
The R/3 System supports two technical types of BOM to represent similar product variants and production alternatives:
Variant BOMs
A variant BOM groups together several BOMs that describe different objects (for example, products) with a high proportion of identical parts.
A variant BOM describes the specific product variant for each product, with all its components and assemblies.
Multiple BOMs
A multiple BOM groups together several BOMs that describe one object (for example, a product) with different combinations of materials for different processing methods.
When do I Create a Variant BOM?
The term "variant" refers to changes to the basic model of a product. These changes occur when components are left out or added.
If you are producing several similar products that have a lot of common parts, you can describe these products using a variant BOM. This is the case, for example, if you replace one material component with another to make a different product. Variants can also differ by containing different quantities of a component. You create the new BOM as a variant of an existing BOM.
You can only create a variant BOM from a simple material BOM. No multiple BOM can exist for the material.
A multiple BOM cannot be converted to a variant BOM.
The system does not define the technical type until you create either an additional alternative for a BOM or a different variant for an existing BOM.
Variant BOMs are supported for the following BOM categories:
Material BOMs
Document structures
Equipment BOMs
Functional location BOMs
When do I Create a Multiple BOM?
One product can be manufactured from alternative combinations of materials depending on the quantity to be produced (lot size). The product is represented by a number of alternative BOMs (alternatives). The differences between the alternative BOMs are only small. Usually the only difference is in the quantity of individual components.
Multiple BOMs are only supported for material BOMs.
The following graphic shows how a product is produced from different components or different quantities using different production procedures.
The multiple BOM contains components, which are only used in one of the alternatives, and one component, which is used in both alternatives.

Special procurement type for BOM item

Hi Experts
I am creating BOM using BAPI : CAD_CREATE_BOM_WITH_SUB_ITEMS
There is no field to update Special procurement type for BOM item in this BAPI.
Could you please suggest some way to update this.
Thanks in Advance

hi Janardhan,
phantom assembly is the assembly which is not kept in stock rather it consumes directly.
Use of phantom assemblies are as below
Phantom assemblies are assemblies that have their own product structure, but whose assembly does not actually physically exist. The components of the phantom assembly are incorporated directly in the superordinate product. The product structure of the superordinate product contains a reference to the phantom assembly.
example - A car with music system.
During backflush, only the goods movement for the phantom assembly components are posted. The phantom assembly is marked as backflushed but does not trigger any goods movement.
Experts pl correct me if i'm wrong.

Type of bom

hi,
1 may i know what is the difference of material bom and sales order bom?
2 how many type of bom in costing?
thanks

Hi,
BOM Categories:
1. Material BOM: A bill of material that you create for a material is known as a material BOM in the SAP. Material BOMs are mainly used to represent the structure of products manufactured within your company.
2. Sales order BOM: Order You work with order BOMs when you specially tailor the make-to-order production of your products to the requirements of your customers. In order to meet the customer requirements, sales order specific modifications to various assemblies are often required.
BOM Usage:
3. As far Costing is concerned: Many companies have only one universally applicable BOM structure for all areas of their company. So, usually BOMs maintained for Production usage are used for Costing purpose.
Hope this helps.

Batch Number for Valuation Type in BOM item detail

Dear PP Expert.
Is it possible to maintain batch number for valuation type in BOM item detail ? My requirement is for example in bom item 10, component A is maintained with batch number for valuation type so that in production order batch number field automatically filled.
Fyi i have tried user exit : Enhancement for BOM item: PCSD0002. Here we can maintain valuation type for component in item detail in customer tab. But unfortunately valuation type here is not link with batch number for valuation type in Production order.
Regards,
Arman

Hi JH thanks for your quick reply,
Let me describe it more specific, I have two material FG and SFG. Material FG is maintained with valuation type so when we do goods receipt for SFG it's asked to input valuation type in batch field. In stock SFG material qty is separated for each valuation type like batch.
Now i want to maintain in BOM for FG, where component SFG has fix the valuation type / batch so that in production order we don't have to choose manually. Do you have any idea ?

Error in Rush Order type with BOM item!!

Hello,
I am facing a very strange error while creating a rush Order with BOM item.
System Error:
1. No item category available (Table T184 SO ERLA TAQ).
I except the error. I get next error as
2. Structure explosion for item 000010 is not possible.
After this BOM explodes with only first 2 Sub Items ( Item cat for main item is determind as TAQ and Sub Items as TAE) , where as the complete BOM has 7 Sub items.
I have made the required configs in item cat determination in T184 table for order type SO, as follows.
SO ERLA - TAQ for Main Item of the BOM
SO NORM TAQ TAE for the Sub Item of the BOM
The same item (BOM ) works very well in OR/BV kind of sales order types, by exploding the BOM to full level(i.e all the 7 sub items are determined).
Has any one come across such an issue. Please let me know what could be the solution?
Thanks in adv,
Shripad

Hi,
Thanks,
In vov7 for TAQ Item Cat. the structure scope is maintained as 'A'. And that's the reason for Standard order 'OR' , the BOM is exploding properly.
It is only with Rush Order , the BOM is not exploding correctly.

Material type for BOM that should not create production order

Hello all,
We have following situation in our company:
We ship few products say for e.g A,B,C which are part of higer level BOM for product M1 to the customer, before the actual product M1 is shipped.Currently these ship-a-head products(A,B,C) is also part of BOM for M1.
We need to combine these ship-a-head products A,B,C as one product M2 (thinking of a BOM) and ship that M2 to customer before M1 is shipped.
In that case what could be the material type for product M2 so that MRP won't create any Production orders for M2.
Also wondering Is there any other way, other than creating a BOM that could combine products A,B and C and ship to customer a-head of time.
Thanks,
Sre

Hi,
Please create BOM for Material M2 by using usage other than production..

Material type for BOM

i want to know which material type can i use for creatig BOM first level
this material type not qty and value updated also it can't be procured and can't be sold.the main usage of this material is grouping and as assembly of parts.

Hi ,
you can set it following IMG ; and standart customizing gives you some idea about your question
Production -- Basic Data -- Bill of Material --General Data -- Define Material Types Allowed for BOM Header

Procurement type in bom

Hi all,
Can we find out, whether material is procured externally or internally manufactured from BOM.Please reply urgently.
regards,

Hi Tiwari,
Just double click on the component,in CS03.This takes you to the material
master views,where in you can check whether its procurement type is F or F30 or
E.there is no other means wherein you can check directly in BOM.

Sales doc type KB + BOM

Hey SD gurus,
I'm using BOM with BOM usage 5 (Sales and Distribution)
I was wondering which item category group, main item and component item should I use in tcode: VOV4 with sales document type KB (Consignment Fill-up) ?
Best regards,
Bahia.

HI,
i think item categories group- NORM will not work for BOM, so you have to use ERLA,LUMP as your requirement,
KB + ERLA(OR)LUMP + BLANK + BLANK = KBN
KB + ERLA(OR)LUMP + BLANK + KBN = (item category)

Multiple BOM and Variant BOM

Hi Gurus
Just a small question...
Can we change the technical type of the BOM from V(Variant) to M(Multiple).
As that field is always grayed out in editing mode (CS02).
If we can change, how ??
Thanks Vineet

Dear Vineet,
If a product has more than more than one alternative BOM(more than one BOM for the same BOM
usage) for that products under the BOM header you will be able to see the technical type as M -
Multiple BOM.
You cannot change this.
variant BOM
Production Planning and Control (PP)
A combination of a number of bills of material that lets you describe a product, or several products that have a lot of identical parts.
The variant BOM describes each object completely, for example, the product "lamp." Each variant BOM contains all the components. This type of BOM is not configurable.
Procedure
The system allocates technical types:
according to the number of alternative BOMs
When you create the first alternative for a BOM, the technical type is not yet defined. If you extend the BOM by creating an alternative, the system automatically assigns the technical type multiple BOM.
according to the transaction
If you create a BOM using the Create variant of... function, the system assigns the technical type variant BOM. After this, you can no longer create alternatives for the BOM.

Split valuation type pick up in MRP run according to BOM

Dear experts,
We are starting to use split valuation scenario. Initially we have customize split valuation as standard i.e.
1) Creation of valuation type
2) Creation of valuation category
3) Assignment of cat. and type.
4) Local definition.
5) Assignment of valuation category in material.
6) Extend material with valuation type.
What i have customized and tested is working fine. Recently our user have a requirement that, valuation type field should be available in BOM for their clear understanding. Accordingly we have enhance the BOM screen and added valuation type to be choose by user during BOM creation. exit used PCSD0002.
Now here is issue.-
I have parent X and its child Y with valuation type SKF, BOSCH and NRB. I have fixed/specify valuation type BOSCH in BOM. If we run MRP for the parent, system should have to create purchase requisition for child with only specified valuation type in BOM i.e. with BOSCH in this case.
Note - We cant use default proc. valuation type in customization as customer requirement is frequently changes also user specified that, system must have to select valuation type specified in BOM and create proposals accordingly both for PIR and dependent requirement.
Please suggest.
With best regards,
Manish K. Bachate

Hi
You would be very much able to valuate both the stocks separately with what I have recommended
But, with what you are doing, you wont be able to... Reason being, once you release std cost for the externally procured item, say, 5 USD... It will keep on valuating the item at 5 USD only.. Any price other than 5 invoiced by the vendor would hit the Price diff account OR you will have to revise your std cost every time the vendor changes his price
Ideal way would be to keep price control V in the valuation type "External Proc"... With this, you dont need to release std cost for it and also it would valuate the stock at whatever price supplied by the vendor.. Whether 5 or 6 USD
> To summarize, what I am recommending is this
> 1. Your material in this case will have 3 accounting view... [One parent view and One view for IN HOUSE and one for "External Proc"
> 2. Parent view will have Price control V, IN HOUSE will have S and External Proc has V
> 3. In IMG settings for split valuation, earmark IN HOUSE for internal proc and External Proc for purchase
With this
1. Your IN HOUSE stock will be valuated at std cost released by CK24
2. Your External Proc stock will be valuated at the price supplied by the vendor
Hope this helps!!

Give Me Simple Step by Step for BOM

Dear "Gurus"
Past few days iam trying BOM, i dont know the step could you explain step by step for BOM, it will helpful for me.
regards
Mohammed Renu.I
[email protected]

Hi Mohammed,
In Addition to above please find some important notes on BOM:
Type of BOM:
BOM is of 2 types - Pricing at header level and pricing at sub item level..
For pricing at header level go to MM01 to create material master for header material. In basic data1 select item category group as ERLA. also in Sales:sales org 2 there also maintain ERLA in both fields of item category group. Complete the master and save it.
DELIVERY GROUP:
Delivery group is basically used whenever there is a group of material i.e., like in BOM if at all you do no have stock of the sub item and you have stock of main item, system will respond and create the deliver for every item in the records of sales order, dly and billing.
Later on when the stock arrives then we can send the stock to the customer
configuration, you need to activate this in the condition type, also can do it in the item level in the sales order.
If you want to combine a number of items in a sales document so that they are delivered together, you can create a delivery group.
If an item has more than one schedule line with confirmed quantities (for example, after an availability check) the system copies the date of the latest schedule line for this item and displays it on the delivery group overview screen.
When forming delivery groups, the system deletes the earlier schedule lines and copies their confirmed quantities into the latest schedule line.
If a complete delivery has not been requested, as soon as all the items for the bill of material are available, the system generates a correlated schedule line. This allows you to make a partial delivery on the first date on which all the items in the bill of material become available.
In other words, the first day on which all items in the bill of material are available, the system issues a confirmed quantity.
Prerequisites
For correlated schedule lines in bills of material (BOMs) in delivery groups, there are certain prerequisites for the delivery group.
These are as follows:
The delivery group may only contain one bill of material
It cannot contain any fixed quantities
It cannot contain any items that have partial delivery indicator C (one-time delivery)
It cannot contain any partially-delivered items
It can only contain items that can be at least partially delivered
It can only contain items that have a maximum of one requested schedule line
In Customizing for item categories, you can control that the system should generate correlated schedule lines for the delivery group. You can do this by selecting A in the Generate delivery group field for the item category in the bill of material main item.

Now create the material master records for sub items also and in this case the item caegory group will be NORM as usual. save the records.
Now go to CS01 - cretae BOM.
here in the material field enter the name of the header material, enter the plant name in the plant field and in the BOM USAGE select 5 (sales & distribution). Leave the Alternative BOM field as blank. Now press enter.
In the Component field enter the material codes for the sub items and in the ICt column select 'L' - stock item. enter the respective quantities and save the BOM.
Maintain the pricing for the header material in VK11. Since the sub items can also be sold as individual items maintain pricing for them also.
Also check the item category assignment in VOV4. The item category for header item is TAQ and for sub items is TAE.
Go to VA01 - create sales order. Enter the material and the BOM will explode.
This completes your BOM with pricing at header material.
For pricing at sub item level:
For pricing at header level go to MM01 to create material master for header material. In basic data1 select item category group as LUMF. also in Sales:sales org 2 there also maintain LUMF in both fields of item category group. Complete the master and save it.
Now create the material master records for sub items also and in this case the item caegory group will be NORM as usual. save the records.
create the BOM as mentioned above. Maintain pricing for sub items In VK11. The header item pricing is not relevant in this case.
Maintain item category determination in VOV4. Item category for header item is TAP and sub items is TAN.
Go to VA01 - create sales order. Enter the material and the BOM will explode.
This completes your BOM with pricing at header material.

Also check the item category assignment in VOV4. The item category for header item is TAQ and for sub items is TAE.
Sal doc type ItC Gr Usg Hig Itc Cat Dflt C
OR ERLA TAQ
OR ERLA TAQ TAE
Save the settings.
Go to VA01 - create Sale Order. Enter the material and the BOM will explode.
This completes your BOM with pricing at header material.
For pricing at sub item level:
For pricing at header level go to MM01 to create material master for header material. In basic data1 select item category group as LUMF. Also in Sales: sales org 2 there also maintain LUMF in both fields of item category group. Complete the master and save it.

This completes your BOM with pricing at header material.
Sales BOM Implementation:
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.
Computer is the combination of " Monitor,CPU,keyboard,Mouse"
Here CPU consists, Harddisk,MotherBoard,Processor,Ram etc..,
Computer is the Mainitem
Monitor,CPU,keyboard,Mouse are all subitems for Mainitem.
Subitem 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 config this into SAP,
first u need create Computer as Main Item-(item car group- ERLA,if u want to give price on material Level).
Create Monitor,CPU,keyboard,Mouse,Harddisk,MotherBoard,Processor,Ram
as subitems( Item cat group- NORM, but for CPU Item cat group- ERLA)
Now Create BoM, CS01- Computer Include Monitor,CPU,keyboard,Mouse as subitems,
again create BoM,CS01- CPU include Mouse,Harddisk,MotherBoard,Processor,Ram as subitems for CPU mainitem.
In Config: 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 Mainitem Computer:
all the items will be displayed as subitems include Mouse,Harddisk,MotherBoard,Processor,Ram.

multiple BOM
multi level BOM refers to exploding the BOM in a single order at different levels,
for this the crux lies in the item category determination only.
for single level BOM determination at the component level: ( item level)
or lumf tap
or lumf tap tan
multi level bom:
or lumf tap
or lumf tap tan tap(manual item cat) or
or lumf tap
or lumf tap tap
maintain BOM structure in CS01.
ex: if in the case of item level
main item X is entered then sub items 1,2,3 appears, then if u want to further
explode sub item 2 to 5,6. (Maintain the structure also in CS01) then configure at the item category determination level as mentioned above

Planning of Dependent Requirements for BOM Components in Make to Order scen

Hi Friends - I want to execute a full cycle Make to Stock Scenario with Materials planning using MRP.
The scenario will include BOM Components with Routing.
The process flow I want to execute -
1. Create a Sales Order for a Finished Product (Product should have a BOM for Production)
2. Do the product Materials Planning for the Sales Order through MD50
3. Get all the dependent material requirements (both for products as Planned Order and also for BOM Components - all the BOM components should also be planned)
4. Convert Planned Order for Product to Production Order
5. Convert Planned Orders for BOM components to Purchase Requisition
6. Confirm Production Order
To execute this I have done the following
1. I have created a Material Master data for Finished Product (FERT).
2. I have assigned Item Category Group - NORM, and General Item Category group as NORM
3. I have assigned MRP Type PD in MRP 1 View and Strategy Group 20 (Make to Order Production) in MRP 3 View.
4. Now created a Universal (Type 3) BOM for the product with one material component.
5. Now also created a Routing for the Material with two operations having PP01 a control key.
6. Now created a standard sales order for the product.
7. Executed the MD50 for the Sales Order Item.
Now where do I find the BOM components for this material in the Sales Order?
After executing the planning Run MD50 I am only getting the requirements for Product only. I can't see any dependent requirements for the BOM components.
How do I make sure that the BOM components are also planned while the product is planned?
I have checked the component Stock Requirement List - there are no requirements generated from the Sales Order Product BOM.
Pls help me on this. How to do this so that the raw material components are also planned?
Thanks
Purnendu

Hi Dhaval, Sandeep, Ashok - Thanks a lot for your replies.
I have checked the Planned Order Created through Planning Run.
If I click on the Components Tab I am getting following message
No material components were determined
Message no. 61027
Diagnosis
Until now, no BOM explosion has been carried out or no BOM has been created for this material yet.
Procedure
Either explode the bill of material for this material, or
create the components manually by processing the planned order in change mode.
If I try to explode the BOM through Header Menu - Edit> Explode BOM
I am getting the same message.
If I click on the Bill of Material Tab - I am getting the same above messge.
Ashok - I have tried both the Selection Method -
Nil - Selection by Order Quant.
1 - Selection by Explosion Date
But with no effect.
Waiting for your advice.
Thanks and warm regards
Purnendu
