Alternative item group bom

Hi All,
Is there any way we can differentiate between the primary material and secondary material using alternative item in bom
I know we have usage probability strategy ranking in alternative group but i guess they dont specify which one is primary and which one is secondary material
any suggestions would be highly appreciated
Thanks

Usage probability is for MRP run.
Priority is the order in which stock is checked in order to reserve.
if either 100% of A or 100% of B can fulfill the demand then it will pick that component based on priority (A first, B second).
Let us make it a little bit more detailed.
Component A
Priority 1
Strategy 2 ( 100 %)
Usage prob. 30
Qty reqd in BOM : 20 EA
Component B
Priority 2
Strategy 2 ( 100 %)
Usage prob. 70
Qty reqd in BOM : 10 EA
If Available stock
A: 20
B: 10
Component A is picked to make reservation.
If Available stock
A: 4
B: 6
(After MRP run)
pur req for A: 2 EA and
pur req for B: 1 EA
If Available stock
A: 0
B: 0
(After MRP run)
pur req for A: 6 EA and
pur req for B: 7 EA
If either 100% of A or 100% of B cannot fulfill the requirement then MRP run will look at the usage probability and generate purchase orders based on the probability and available stock.
But you want to purchase either component A or component B (according your requirement where you want to make one of them primary) It makes little sense to set one at 30% and other 70% so you set that component usage probability for primary as 100% and rest of the components in the group 0 so that pur reqs are generated only for the primary.
Example you always want the system to look for A if it's in stock and can fulfill demand but you always want to purchase B first, so you set priority 1 for A and probability 0 and usage probability 100 and priority 2 for B

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

Alternative item in BOM

Hi Experts,
I have a scenario. A is a FG and X and Y are the child items. We want to use X or Y is a alternative items in the BOM. i.e If X is available in the system, system backflush the quantity from X and if X is not there system backflush the quantity from Y. And if X is available in partial quantity, sytem backflush first quantity of X and then balance Qty from Y. Priority given to X is 1 and to Y is 2.
How can I maintain following fileds in BOM thru CS02 in Both X and Y.
Aternative item group
Priortity
Stragetegy
Usage Probabilty
GR

Hi G R,
Find below an example from a forum member - Mr. Mangalraj, i think it is one of the best ones to help understand the concept & usage. If after reading it, you need any more info revert.
Regards,
Vivek
Eg:
If there's a material Alt2 which can be used instead of a material called Alt1,now we will first form an Alternative item group using this 2 material.It can be more than 2 materials also.
Now in our case after u enter Alt1 as the line item for a HALB or FERT,select that entire row and click on Item details or Press F7.In Item data screen,in the bottom under general data u can find the field for Alternative item group.
Click that and enter the values as follows
A-Alt Item Group
2- Priority
2- Strategy
70% - Usage probability ,now come back.
Now enter Alt2 as the line item and after that as i said select that row & press F7.
Click on Alt.Item group button and enter the values.
A,
1,
2,
30%.Now save.
Now let's assume this BOM is used for a HALB.Let's assume 10 quantity is mentioned in the BOM for each of this line item.
Now if there's PIR for say 100 quantity
After running MRP for the HALB the requirements will be seen as Alt1 700 required & Alt2 300 required.
Here for the planning Only Usage Probability comes into picture.
When you are doing the production booking for making 100 quantities,the system shows 1000 quantity of Alt1 and no Alt2 will be seen in good's movement's screen.
Now the priority comes into picture,as we have given priority as 1 to Alt1 the systems proposes 1000 quantity of Alt1.
So while planning Only usage probability is considered and requirements fallas as per that.
While doing Production booking priority comes into picture.
So Here as we have maintained priority 1 and strategy as 2 for Alt1,the systems proposes 1000 quantity of Alt1.
If your strategy is then the planning & production will be as per the usage probability.
Second case:
If for Alt1 A & for Alt2- A
2 1
2 1
70% 30%
Planning will be 700 & 300 of Alt1 & Alt2.
But for production booking 1000 & 300 of Alt1 , Alt2 will be proposed by the system.Because For Alt1 though the priority is 2,but its strategy is 2.
For Alt2 priority1 but strategy is 1(Manual maintenance).

Alternative Item group not appearing CS11

Hi all,
We have created BOM with all the substitution materials which can be used at the time of Production.
We have utilised the Alternative item group for this. When i look at BOM for a material say X using CS03 i can see the Alternative Item group. But when i explode the BOM using CS11 i cannot see the alternative item group in it.
The scenario in details is :
For the header material X i have X1,as component with different change numbers and unique validity dates and this component is seen in 3 lines in BOM with alternative item groups against it.
Now when i explode the BOM using CS11 i can see X1 component with alternative group for only 2 line items.
We are in ECC6.0 version, can i ask you whether there is any patch or oss note to be applied.I have tried searching OSS notes but couldnt find them
Please advice as this is of very high importance.
Thanking you
Regards
Raj Kiran

Dear Raj,
What I wanted to confirm from you is ,after executing CS11--->
Changing Layout -
> Selecting Alternative Item group,
priority,Usage probablitity,the values are not shown in the field
properly though they are actually present in the BOM?
So enter the proper valid from dates in CS11(Select the date
on which the alternative item group is active) & also alternative
BOM number properly.
So go ahead as I suggested and even after entering the proper
valid from dates,Alt.BOM---changing layout ,if its not giving
proper results,then go for checking OSS notes.
This is with respect to ECC 6.0.
Check & revert back.

Alternate Item Group functionality in BOM

Hi PP Gurus,
I was looking into the Alternate Item Group functionality in BOM and found it interesting for my business requirement.\
But I am facing one problem as below:
I have 3 components for Eg. A1, A2, A3 in my header material 'A'. All the three component materials are same but quailty of the 3 is different and also the standard price.
My requirement is whenever I am creating Production material for header material 'TEST_Header_Material, the system should look into A3 first (Cheapest), if not available then A2 (Cheaper) and if not then A 1(expensove of all the three).
For base quantity for A = 1EA, I have entered 1 EA for A1, A2, A3 in BOM. I have stock of A1=9, A2 = 6 and A3 = 2.
When I am creating Production Order for A = 10 EA, ,yrequirement is that the system should consider A3 first, then A2 and then A1 based upon the prority and hence should withdraw A3=2, A2=6 and A1=2 for meeting the quantity for finish product A in Production Order. But actuall the system is considering A3 but confirming it as 0, then looking into A2 again confirming it as zero and then looking into A1 and again confirming it as 0. And thus giving Missing Part list though I have sufficient quantity to cover the requirement.
That means system is only considering total quanitty.
Can you please advice?
Thank You.
Rahul.

Dear Rahul,
Priority:In this field, you define the priority of the item within an alternative item group. This determines the priority for planned
withdrawal of items. Two items are assigned to an alternative item group (A1) with the following values for priority:
Item 0060 Value for priority: 02
Item 0065 Value for priority: 01
The system reads item 0065 first.

Alternate Item in BOM

We are manufacturing a assembly using alternate raw materials say RM1 or RM2 or RM3.
We want to define these three raw materials alternately in such a way that;
1.     If stock of RM1, RM2 & RM3 is available, then system should consume the RM1 first always.
2.     If required qty is 100. Stock of RM1 is 40, RM2 is 30 and RM3 is 100. In such condition, system should consume                the 40 qty of RM1, 30 qty of RM2 and 30 qty of RM3.
3.     If stock of RM1 is zero, then system should consume the stock of RM2.
4.     If stock of RM1 and RM2 is zero, then system should consume the stock of RM3.
Please guide how to create a BOM to fulfill above requirements.

Dear Sachin,
In my understanding the system allows to maintain the priority,strategy and usage probability for the items grouped under
alternative item group.
Priority:This determines the priority for planned withdrawal of items.
Example:
Two items are assigned to an alternative item group (A1) with the following values for priority:
Item 0060 Value for priority: 02
Item 0065 Value for priority: 01
The system reads item 0065 first.
*Usage probability*MRP plans these alternative material components according to probability of use.
In this field you enter a percentage to show the probability of using an object in production. Material requirements for the BOM
components are planned according to the usage probability.
The system does consumes the items as per the stock availability automatically.
So in your case even stock determination will not work,as this decides only in what sequence the stock should be consumed for
a material(from which storage location to which storage location).
Check and revert.

Alternative Item Strategy 2

Hi,
We use Alternative Item Group to automatically select items of phantom assemblies with 100% availability, during process order release.
In the item detail screen of the phantom material's BOM, Strategy is 2 and priorities are assigned to components.
In Customizing OPJK, "Check material availability when saving order" is selected.
Component check type is ATP check.
This Phantom material is used twice in the BOM explosion of the finished product.
However, when the finished product's order is released, item withdrawal quantities for the phantom is determined according to priorities (which is true) for one and determined according to usage probabilities for the other.
Any ideas on how to fix it?
Thanks in advance.
Edited by: Deniz Ozgenc on Dec 24, 2009 5:03 PM

Purna,
This is not possible in standard SAP. SAP has provided only two options for this. The one which you explained and the other in which you define the percentage of usage probability.

Alternate Items in BOM

Hi All,
I have the following scenario, i am creating a BOM in which for one material there are two alternate items. Here i mean if Material A is the main item, and if this not available then we need to use both Material B and Material C.
We have alternate items but this is a case of two items been required to replace one. How do I set the BOM in tis case?
Do i need to go with Alternate BOM...? That is BOM 1 with Material A and Alt BOM 2 with Material B & C.....Is this the only way..?
Thanks for your review and feedback
Regards,
Srinath V

Hi ,
For This situation may be it is convenient apply Phanton?
-The Father Product (X), have as component
the Prod A and it is replaced by A1 , using option Discontinuation DATA
The Prod B and it is replaced by B1 using option Discontinuation DATA.
Phanthom X
            item A
            Item B
Phantom X1
           Item A1
           Item B1
Constraints
Only we can use simultaneously A with B
or A1 with B1, (We can't use A with B1 or B with A1)
How we must config Built of Material ( Discontinuation Data or Alternative Item Group, using discont group,followup group) and MM02( discontinued parts)
We need use item A/B until the stock was consumed, so we wil use Item A1/B1, and MRP must to calculate needs based on items A1,B1
Thanks for you attention!

Assigment of alternative items in Routing

Hello All,
In a BOM, Material A and B are alternative items with same item no. (grp-01,prior -1, strategy-1, usage prob A=100, B=0).
In routing, material A is assigned to operation 0010 and B assigned to operation 0020.
But when prod order is created, A and B both shows that they are assigend to same operation (either 0010 or 0020 whichever is assigned last).
Please say me why it is not assigned correctly.
regards,
ranjit

Hai ranjit kumar,
If you use alternative item in BOM, then system will read material component that belong to the same alternative group and strategy as one component. The principle of alternative item is there are few material code that can replace one item component BOM especially for good issue/reservation. In your case, why you assign alternative item B into operation 0020?? It should be in operation 0010. If you want to allocate material A to operation 0010 and allocate material B to operation 0020, then you must not set material B as alternative material A. Remember that alternative item will be substitute for the other when good issue is done. So, the system only propose one operation which component will be allocated.

Concept of alternative items

dear gurus,
 can any body explain the concept of alternative items.ie if 1 material is not there we can use other material.whether it is correct?what are all the other uses in using alternative items.please explain the configuration also
 - gide

Hello Mr.Gide,
I'm not willing to give you definitions & explanations for Alt.Item,
Group,
Priority,
Strategy,
Usage Probability.
Kindly check in SAP Help.
Let me put some practical inputs.
Eg:
If there's a material Alt2 which can be used instead of a material called Alt1,now we will first form an Alternative item group using this 2 material.It can be more than 2 materials also.
Now in our case after u enter Alt1 as the line item for a HALB or FERT,select that entire row and click on Item details or Press F7.In Item data screen,in the bottom under general data u can find the field for Alternative item group.
Click that and enter the values as follows
A-Alt Item Group
2- Priority
2- Strategy
70% - Usage probability ,now come back.
Now enter Alt2 as the line item and after that as i said select that row & press F7.
Click on Alt.Item group button and enter the values.
A,
1,
2,
30%.Now save.
Now let's assume this BOM is used for a HALB.Let's assume 10 quantity is mentioned in the BOM for each of this line item.
Now if there's PIR for say 100 quantity
After running MRP for the HALB the requirements will be seen as Alt1 700 required & Alt2 300 required.
Here for the planning Only Usage Probability comes into picture.
When you are doing the production booking for making 100 quantities,the system shows 1000 quantity of Alt1 and no Alt2 will be seen in good's movement's screen.
Now the priority comes into picture,as we have given priority as 1 to Alt1 the systems proposes 1000 quantity of Alt1.
So while planning Only usage probability is considered and requirements fallas as per that.
While doing Production booking priority comes into picture.
So Here as we have maintained priority 1 and strategy as 2 for Alt1,the systems proposes 1000 quantity of Alt1.
If your strategy is then the planning & production will be as per the usage probability.
Second case:
If for Alt1 A & for Alt2- A
 2 1
 2 1
 70% 30%
Planning will be 700 & 300 of Alt1 & Alt2.
But for production booking 1000 & 300 of Alt1 , Alt2 will be proposed by the system.Because For Alt1 though the priority is 2,but its strategy is 2.
For Alt2 priority1 but strategy is 1(Manual maintenance).

So many combinations can be made using this.Dont get confused.
If satisfied,plz reward points to all the answers which helped u and close the thread.

MRP for alternative items

Dears,
We have requirement from client that , they need to plan alternative items for their spare parts, scenario is as follows.
Header Mat is X and Components are C and D, here C and D are alternative to each other.
If we run out of stock for C, and there is stock for D, when we run MRP for C
it should give only the delta requirements and not full meaning C = planned qty - stock of D .
I am very much sure that Alternative Items in BOM Explosion will not support this scenario, please suggest any alternative / workaround solution only in ECC/R/3(not in APO).

Hi,
In BOM go for alternate group, here you can maintain check either 100% stock of component to be selected or with % of both components. After creation of production order you can check result of actual reserved componets. No effect at the time of MRP run.

Suhas

Alternative Items in specification

Hi all.
In standard system we can create alternative items in BOM with relationship 1 to 1. For example main component "A" and alternative component "B". In case, if during withdrawal postings component "A" is not available system change it on alternative item B.
How we can create alternatives for groups of component?
For example group of main component "A1" & "A2" in case of absence "A1" or "A2" must be changed on group of alternative items "B1" & "B2" & "B3".

Hi Eduard,
I don't think so for Group of components as you said A1/A2 should be replaced with B1 or B2 if it is unavailable. Same requirement I faced but that was at MRP level. And logically A1 might be having some components/materials under it so how system will identify for particular component in group A1 replacement is particular component of group B1. So it would be better to maintain Alternative components by assigning it to respective BoM components.

Abu Arbab

Alternative item concept

hi pp friends,
i have a scenario in which alternative items are required for selection purpose based on stock avilable ie. the alternative item which has highest stock must be selected.
Can you pl. detail me the steps how to map this scenario.
Regards
Laxmikanth

Laxmikant,
I will explain you the concept with an example.
In one FG lets take X, Y, & Z are meant to use as alternative to each other.
Enter all the componenets i.e. X,Y,Z as a component in FG BOM.
Fill up the required data i.e item category, quantity.
Now select all the three items & click on item details.
In the 'Basic data' tab page of first item i.e. X, give 'Alternative item group as 'A1'. (It can be any numeric or alfanumeric value).
The pop up will appear, enter priority as 1, strategy as 2 i.e. 100% (strictly in your case. Do not enter 1).
Usage probability anything but don't keep empty, say 50.
Now go into item details of the next componenti.e. Y, give 'Alternative item group as 'A1'. Similar to what you entered in first component.
The pop up will appear, enter priority as 2, strategy as 2 i.e. 100% (strictly in your case. Do not enter 1).
Usage probability anything but don't keep empty, say 25.
Now go into item details of the last component i.e. Z, give 'Alternative item group as 'A1'. Similar to what you entered in first component.
Repeat the entries in the pop up as in case of Y.
Save the BOM.
Now whenever the order will be created or released during the availabilty check system will check the stock.
Out of this three the component which is available more than the require quantity will be booked depending upon the priority, other two will be copied in the order with the nil quantity.
Two important things, you should have OPJK setting in place for that order type with material availability check ticked.
And second the stock of any of the component must always be more than the require quantity in the order or else system will book the compoenent as per the usage probability entered.
Hope this helps you.

Partial substitution of alternative item material

Dear guru.
I have a bom with two alternative item (A and B) with same group.
I need that mrp create dependent requirement only for A and nothing for B.
After atp check if B is available and A isnu2019t available I need that the system create requirement for B for the available quantity and create requirement for A for the remained quantity.
How can I set the alternative item data group of bom for these two component ?
Thanks.

Hi,
I hope that I understood you right;
The set up of the alternative item group in the BOM should be like this:
Priority - 1 for A, 2 for B
Strategy - 1 for both
Usage Prob. - blank for both
Alternative item group - same for both
Now this works like this:
MRP will always plan A.
When ATP is checked in production order it looks first for A. If A not available or available quantity not enough, then it looks for B.
Be aware of system behavior when using this with backflush and overproduction! There is a note on this!

Mario

Alternative iteam group

how to create an alternative iteam group for the bom .
what is the use of it

Hi
You can go through the following notes which is self explanatory.
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
Pl. try in these lines .
If you still have problem pl. get back.
