AltItem Group in BOM / Alternative Material

Experts,
In Assy A I have two materials B & C in BOM, I like to route the demands to material B as long as I have enough material on stock. If I have no stock or not enough of material B to cover demands of Assy A, system should automatically switch demands to material C.
Is there a way to set this up in SAP, ideally with MRP support to calculate demands between B and C.
Thanks in advance
Jörg

Dear Sir, in your case the item B and C are alternate items .For this you have to define the tewo material as alternate one.
SAy e.g B abd C are line item 10 and 11 respectivelly.Double click onthe first line item define a alternate item group,
than define priority Strategy and Usage probability.
Say for example
item   Alternate Item        Priority      Strategy      Usage Probability
B         X                              1             2                          100
C     X                                 2           2                               100
For any issues please revert back

Costing shows high value due to BOM alternative material

Hi,
In BOM we have maintained alternative material for few line items.(not maintained alternative BOM) When we do the standard cost run system is taking main material and alternative material value. so the cost of the product is showing high.
How system will behave this situation when doing standard cost estimate? how to avoid this excess value due to adding the alternative material?

Dear Govindaraj,
If there are alternative items maintained in the BOM,then as per the usage probability defined for each
item the cost will be taken.
say for one item if its 60% and for the another if its 40% means accordingly the cost gets captured.
So goto CS03,say Items X and Y are defined under alt.item group A1,now select the first item(row) X
and click on item details and check under Basic tab page you will be able to see the alt.item group
along with priority,strategy and usage probability.
So in CK11N or CK40N,it will be showing as 6 ea and 4 ea along with their prices for costing part.
So as per to the usage prob it picksup for the costing part.
Check and revert back.,

Bom alternative item group

Hello Experts,
I have one issue in BOM alternative item group I have made the settings as below.
Material 1     AltItemGroup         01
                     Priority                                  1
                     Strategy             2 100% check
                   Usage prob.         100
Material 2     AltItemGroup                      01
                      Priority                                  2
                      Strategy             2 100% check
                      Usage prob.         100
For Material 1 required bill of material quantity is 65 MT
For Material 2 required bill of material quantity is 65 MT
Now I am creating the process order for quantity 1000 MT. When the material availability check done it proposing as below in process order.
Material 1 = 65 MT    (Available Stock 807.109 MT)
Material 2 = 0 MT      (Available Stock 5.850 MT)
And again Material 2 = 32.5 MT
My question is as per above settings and stock situation of the material it should propose only Material 1 = 65 MT. But here system is also proposing Material 2 = 32.5 MT. Can any one tell what I am doing wrong?
Any settings are missing or what will be output for the above settings.
Please explain in detail.
Thanks in Advance
Regards,
Ganesh

Hi Ganesh,
Pl. make the following settings:
Material 1 AltItemGroup 01
Priority 1
Strategy 2 100% check
Usage prob. 100
Material 2 AltItemGroup 01
Priority 2
Strategy 2 100% check
Usage prob. 0
The strategy 2 will automatically handle the situation when Material 1 is not available and 2 is available.
Pl. test & revert. It will work as per your requirements

How to maintain alternative material in a BOM for a component.

how to maintain alternative material in a BOM for a component.if stock for existing bom component is less then it should consider other alternative material in the same BOM

HI,
You can maintain alternate material for BOM Component by specifying Alternate Item group as below;
Go to CS03/CS02--> Items-> Select Component and go to details->Basic Data Tab--> General Data
Pls. find more details about Alternate Item group maintainance as below:
Alternative item: group
Consolidation of alternative items within a BOM. Every material in the assembly can be included in the alternative item group.
Use
As soon as you enter an alternative item group, you see an additional dialog box with the following data: ranking order, strategy, usage probability.
You can maintain alternative items in the following situations:
Alternative positions with specific usage probability
These alternative items are incorporated with a specific usage probability. Enter the usage probability for each alternative item in the group, so that:
dependent requirements are determined in requirements planning
dependent requirements are changed to a reservation in the production order
Alternative positions as information
You can enter an alternative item for information purposes. This item would then, for example, only be taken into account in situations involving missing parts.
As there should be neither dependent requirements nor a reservation for this item, enter no usage probability.
Procedure
Enter the same character string to denote the alternative items of an alternative item group.
Enter the same strategy for all alternative items in the alternative item group.
Dependencies
Alternative items are valuated in the following way:
Dependent requirements determination
Requirements planning determines the dependent requirements according to the usage probabilities that have been entered.
If the usage probability is 0%, then no procurement is planned for the item. For information purposes, however, dependent requirements with 0 as quantity are created.
Withdrawal posting
You can control the withdrawal posting for the resevation in the production order in the following way:
Withdrawal according to usage probability (manual change is possible)
Withdrawal if there is 100% availability
(Check ranking order and strategy)
Example: See Strategy for alternative position
Further you can also maintain alternate material if you want to stop using this material at certain time as below:
In material master of the material ,
Go to MRP-4 View----> Under Discongtinued parts specify
Discontinuation Indicator
Eff-out.
Follow-up matl
So system will automatically consider follow up material in BOM as per the settings you have maintained for the material to be replaced.
Hope this helps.

Tejas

Alternative material in BOM

Dear SAP Friends,
I have a BOM with 1 material & want to add 1 alternative material if previous one is not available in stock.
pl tell how to create alternative material in BOM without creating alternative BOM.
Regards,
Chandra.

Hi chandra
Alternative items can be added to the BOM without alternate BOM.
In change mode of BOM CS 02 go to BOM item details There you can see alternative items with item group
There you can define you items with Priority,usage probability , Strategy,
Alternate item will be selected during MRP run as per your usage probability

PR( purchase requ) for Alternative material in BOM

Hi PP expert,
I am using alternative material in BOM. As for example my Header BOM material is u2018Yu2019 and his alternative components are X1 and X2
I have done setting in BOM
For -
X1,------
Priority ---1
Strategy - 2 ,100%
Usage prob     100
For -
X2----
Priority -
2
Strategy - -
2 ,100%
Usage prob    -
0
My client want when run the MRP , PR should be generate of material u201CX2u201D ,because there is no X2 stock and Material u201CX1u201D have more stock and want to consume X1 material 1st then X2.
X1 has been blocked for procurement.
Kindly suggest me how will generate PR of X2 when the run MRP. X2 is alternative material..
Regards,
Aqueel

Hi Aqueel!
      As I know, standard SAP cannot solve your problem. Howerver, you can try with these way:
          1/ Try to estimate how long your company will consump all X1(Ex 3 days). Use Alternative BOM 1 for X1, Alternative BOM 2 for X2. And allocate Alt 1 to Production version 1 with valid to 8/10/2010, Alt 2 to production 2 valid from 9/10/2010.
          2/ Change:
          For -
X1,------
          Priority ---2
          Strategy - 2 ,100%
          Usage prob 0
          For -
X2----
          Priority -
1
          Strategy - -
2 ,100%
          Usage prob -
100
And Run MRP, system will take X2 into accout. If you want to savage X1. Need to calculate it and manually change in comonent list of Production order (Now, X2 will consider) with X1 until X1 stock finish.
Hope it can solve you problem(not perfect).

Creation of alternative material in production

Dear folks,
I have following requirements:
Customer orders Material A and for some reason (e.g. low stocks), the mrp controller decides to produce an alternative material (B) which is
equal to Material A. This also counts for planned independent requirements.
How can I maintain this in SAP? I tried to use alternative item group in the BOM, but this does not solve my requirement, since this is just a function to assign an alternative BOM position for Material A. I really need to assign an alternative material on header level.
The assignment has to take place before actual production. We cannot use Material Determination (SD) - Transaction VB11.
Any ideas? Is this something we have to develop?
Kind regards,
Peter

Subcontracting & BOM alternative

Hi:
I need be able to select a BOM alternative into the Purchase Order for Subcontracting.
I mean, I've more than one option to make a material in subcontracting (different items for the same material) , then I'd like be able to make this decision.
Anybody can help me?
Regards
Omar Perea

hi
i think u need multiple BOm section i.e. alternate BOM,u can achive this using production versions
for this u have to do following
1. Define all the materials in your plant (subcontracting and packaging etc).
2. In the material master MRP 4 view there is one field in which you can mention that this material is not relevant to MRP planning, use this field for subcontracting material so that it will not be planned in MRP runs ( generally use this field for re-order point planning).
3. In the BOM for the subcontracting material put the special procurement key as Subcontracting and do not keep relevance for costing.
4. If you're using packaging material of your company and want to capture the cost of these materials in the subcontracting production order then put relevance for cost.
5. Define alternate BOMs for each customer.
6. Generally the routing will be the same but materials will change, define different prodcution versions for each alternate BOM and assign to the routing.
7. Define the activite types for packing and mixing in the work center and assign them to the cost center, use these for your routing.
8. Whenever you recive a sub-contracting order, use the relevant production version depending on the customer.

Requirement of an alternative material

Hi,
i have a requirement for a none stock material NLAG.
Normaly such materials doesnt allow stock. I want to have something as an alternative materialnr which should be used for stock postings.
That means i have several "none stock materials" which should be linked to one material which handles the stock postings.
Perhaps a NLAG material is the wrong material type.
The process should work like that:
- Entering a sales order with the "none stock material" with ATP check to the alternative material
- Delivery with none stock material, but on goods movement side allways with the alternative material
- Invoicing again with none stock material
So that means sales module should work with the "none stock material" and logistic side should automaticaly have the posting one one corresponding material.
Like a group material.
Perhaps somebody has a good idea.
Thanks

Hi carl,
i hava the same problem,
can you show your solution?

Item Category Group in BOM

Dear Gurus
I want to create the BOM for Computer = Screen + Herdisk + Key board
1) Main Item Level processing
I have maintained item category group ERLA in MMR (Sales 2 screen) of the finished product
(Computer 1 ).
What item category group should be maintained for sub items?
2) Subitem Level Processing
I have maintained item category group LUMF in MMR (Sales 2 screen) of the finished product
(Computer 2).
What item category group should be maintained for sub items?
3) Also explain about how to mainatin the master records (CS01).
Regards,
Ashish
Edited by: Ashish Desai on Apr 8, 2009 1:10 AM

Ashish,
Suppose the material is completed then the value is shown against final product. In that case we use Item vategory Group ERLA. The maina item category will be shown as TAQ. The Subitem will take item category TAE (text item)
If the material is still not complete then the value is ascertaind through sub items in that case LUMF item category is used and item category for the main item is TAP and for sub items it is TAN.
In any case we will change the item category group as (ERLA or LUMF) in the material master of the final material "Computer". Where as the subitems item category will be "Norm".
Note: If you use standarad Order = OR, and standard item category group ERLA in the Finished MAterial Conmputer, then system will automatically assign item categories for Main item = TAQ and SUb Items = TAE.
Standard process and ORder = OR
Then Execute MM02 for finished material or Main materialo alone i.e., "Computer", Assign Item Category Group = ERLA and save. Then create BOM CS01, CS11 Single level the output will be
COMPUTER = TAQ
SCREEn = TAE
HERdisk = TAE
Key board= TAE.
Similarly if you proceed process by changing Item category group = LUMF for main material i.e., Finished goods "Computer" then
COMPUTER = TAP
SCREEn = TAN
HERdisk = TAN
Key board= TAN
If you are changing the document type prefixed with Z , then you need to proceed with "Assign tem Catgeory"

Alternate Group in BOM

Hi experts,
I'm having the problem with Alternate group in BOM. I'm maintaining the the raw materials in BOM i.e A1,A2,A3,A4 like that number of materials is there.
I'm grouping the materials with alternate group
A1: Alt Grp-01, Priority-1, Strategy-2, Usage-100%
A2: Alt Grp-01, Priority-2, Strategy-2, Usage-0%
A3: Alt Grp-01, Priority-3, Strategy-2, Usage-0%
A4: Alt Grp-01, Priority-4, Strategy-2, Usage-0%
I given the qty for all raw materials is 100kg.
While i'm converting planned order to Process order. The BOM materials is taking as
A1 - 1000kg
A2 - 0kg
A3 - 0kg
A4 - 0kg
Why 1000kg taken and I don't need the materials A2, A3 and A4 in the process order. Is there any option to get drop-down list. May be its customizing.
Naren

Dear
Why do not your go for Discontinued Material concept in case if you think that A2/A3/A4 should be be considered based on the stock avaliablity .
In MRP4 view for material A1 , you can keep the Discontinued Material , Effective Out Date , Discontinued Material Indicator as 1 so that when ever there is a stock un-availablity , it should be considered while planning and sub sequently in process order .
When copiying BOM to Prococessd order , there is no operatunity to change the qty because it happens automatically based on the order type dependent parametrs for process order (OPL8 ) but you can change the qty in process order change mode -compoenet over view .
If you are maintaining production verion , you can implement BAdI MD_MODIFY_PRODVERS or MODIFY_PRODUCTION_VERSION based on stock situation .

BOM Alternative Check on CS01 screen

Dear All,
Right now i need to implement a user exit for the BOM alternative in CS01 screen. For a particular BOM Usage we should not allow the user to create alternative other than '1'. So before getting the automatic alternative i need to implement the user exit/Badi for the checking on the alternative.
thanks,
rajesh.

Hi,
There is a standard customzing for alternative BOM in CS01...
SAP Customizing Implementation Guide --> Production --> Basic Data --> Bill of Material --> Control Data for Bills of Material --> Define Modification Parameters. If you tick the " Multiple BOM inactive" then nobody should be able to create other alternatives then 1.

Routing link to BOM alternative

Hi all,
In our current SAP solution (SAP R/2) each routing alternative stores a link to an associated Bill of Material alternative. We have noticed that in mySAP ERP the routing alternatives can store BOM alternatives in the Component Allocation tab, but if you look at the header table for routing PLKO there is a field for associated BOM alternative (STLAL). If we select a BOM alternative this field is still not populated.
Does anyone know where this link is stored? Does the new system assume that production versions are created to store this combination of Routing and BOM? We would appreciate the insight. Thanks!
Sincerely,
Justin

Hi Justin,
Suppose you have two BOMs ,alternative 1 & 2. T.code cs01
To change T.code cs02.
A routing is created for the header material. T.code ca01.
To change T.code ca02.
In the routing, if you click the component allocation tab, you can see both the alt BOMs. From here you can select the BOM you want & then save. All the material will be allocated to the first operation by default.
Reg. Prod version:
You can create eg version 1 Routing + Alt BOM1
version 2 Routing + Alt Bom2.
In the material master, mrp view 4 check the options Bom selection , here if you give as selection only by prod version, during prodn order creation, the system will inform that there are two prodn versions & which one to select. This selection of pron version can be made manual or automatic. Given in T.code opl8

BOM explosion where first BOM alternative has deletion flag

Hi,
I got the following very basic scenario:
One FERT material has two BOM alternatives (alternative 1 and 2). Both of them are valid in terms of date, status and lot size. When a production order is created by CO01 the system will pick automatically alternative 1 (which is ok for me). BUT if this BOM alternative 1 gets a deletion flag (on BOM alternative header) I would expect that the system would automatically pick alternative 2 (it is the "next" suitable alternative). But the systems says there is no valid BOM available.
Only if I really delete alternative 1 (so I cannot see it anymore in CS02), the system would pick alternative 2 (because it is now the really first one available - no version in front with only deletion flag). But in terms of documentation I cannot delete the alternatives.
Maybe somebody could explain that to me or had a similar problem...
BR and thanks in advance.
Christian

Hi Guys,
many thanks for your suggestions. Setting the status to inactive did the trick. Obviously the deletion flag is not enough at this point.
Just to clarify - production version of course would be an option but that did not work with the following:
I have 6 different routings for this FERT and the user has to choose when the production order is created. That works basically fine when the order is created with CO01 (popup for selection of production version based on MRP4 setting). BUT when a planned order is converted directly from MD04 into a production order the system would automatically pick production version 1 (no matter what setting in MRP4 view). If there are no production version the user would get at least a popup for choosing a routing. But this would maybe an additional thread in the forum
Thanks
Christian

SD-PP integration: BOM alternative

hello, friends. i wish to ask you about transfer of requirements from SD to PP.
when processing the sales order, the user can manually select the BOM alternative via a dialog box. in standard, BOM with usage 3 (universal) and 5 (SD) are supported.
i notice that after we run MRP, in the planned order the BOM usage is 1 and alternative is defaulted to the first in the order sequence. this is true if the BOM selection method in the material master MRP 4 view is either for production version or blank.
if the selection method is by key date, then the BOM in the planned order will be the first in sequence for alternatives by key date.
in variant configuration, the specific requirements are transferred. but for a simple BOM, in neither situation is the alternative selected in the sales order transferred. why is this so? are there missing settings?
hoping for your valued inputs.
many thanks.

Hi
In case of Variant configuration(VC) , the BOM Selection will be based on Dependencies assigned to the Components. In VC there is no alternative BOM Concept. There will be one Simple BOM called Super BOM which contain all the components which is required to make all the variants of K-mat.
In the sales order , the user will configure the requirements and based on the requirements selected in SO , the system will pick respective Components from Super BOM during MRP
