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 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.

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
shaiil

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

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).

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.

Access Item Group Item of BoM

Hello everyone,
I'm trying to find/create an unambiguous link between the items that appear in a supply to production task and the line item of a Bill of Material (BoM) it's based on. The reason for this is that a customer would like the `line item details text' field that appears below each item in a BoM to appear on the supply to production task form in the same row as the corresponding item. Unfortunately this doesn't seem very simple --- practically all links back to the PBoM business object eventually lead to collections, which don't provide unambiguous links. I can't use material ID as a BoM variant can potentially have multiple versions of the same product but with different base quantities etc., so that's out the window. I found that going through production lot > released execution production model > production segment leads me to be able to grab the BoM/Variant/Item Group IDs fine, but the association that supposedly links to item group item is not set --- my guess is that this association is the one I need. Below is a screenshot of the code I'm using to try and access this --- as you can see, the ProductionBillOfMaterialItemGroupItem association is not set in either case, yet the corresponding association for item group is, and returns the correct item group ID. Anyone able to help/have experience with this? Thanks.
Lewis

Spoke to SAP about this. Whilst there's a 0..1 association from AcitivtyAssignment to ItemGroupItem, it's never set. Which makes me wonder why it's even there in the first place, but never mind.
They suggested going via ItemGroup first. When I did this there was no 0..1 association from ItemGroup to ItemGroupItem, merely a collection of all items in the item group. When I pointed this out, they acknowledged that there is no link. So basically, this isn't possible per se; what I've done to emulate it is a bunch of calculations based on quantity etc., as well as use the ability to manually set the item group ID of a row in a BoM, to ensure I can reliably find the row of a BoM a production task row refers to. I suppose it's case closed on this; if anyone's interested in the code, they can send me a message.

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.

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.

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

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.

For Alt2 priority1 but strategy is 1(Manual maintenance).

So many combinations can be made using this.Dont get confused.

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.

Alternative items

dear gurus,
i came to know that we can maitain alternative items for eg) a-header material b-bom component .if b is not there we can use c.ie c is the alternative item.how to configure in bom.can any body explain the sub-items in bom?what is the difference between sub items and alternative items.please explain
-gide

Hi,
In BOM alternative items are assigned to alternative item group on the general
data.
In the production order in the general data tab page.
We can define the alternative item based on priority , strategy and usage probability.
Priority:
This defines the priority of the item within the alternative item group.
This determines the priority of planned withdrawls of items.
EX Two items are assigned to alternative item group
item A Priority 1
item B Priority 2
The system reads the item A first.
Strategy:
use the strategy to determine how the planned withdrawl is controlled
within the alternative item group.
The strategy should be same for all alternative items within a alternative
item group.
If the value 2( 100% check) is defined for the strategy the first material in
the defined priority sequence for which sufficient quantities are available
are reserved.
Usage Probability:
MRP Plans these alternative material components according to probability
of use.Material requirements for BOM Components are planned according
to usage probability.
The planned withdrawls for the production order are based on the
reservation lists.These lists are based on the priority and strategy.

Alternative item with follow-up material

Hi,
I have a finished product X for that component A-1 pc and B-1 pc is required.
Now A cannot be used in next year thatu2019s why my client wants 1) to issue 2 pcs of A instead of A-1pc and B-1 pc until the stock of A is available. 2) If the stock for A is not available then only it goes for B.
1) I have used alternative item grp with priority: 1, strategy : 2, usage probability 200% for A and priority: 2, strategy : 1, usage probability 0% for B
System issues 2 pc of A only
2) Also maintained follow up material as B so if there is any shortage for A then system is looking for B.
Problem is with the above setting the follow up material and alternative item is not working together. System issues only 1 pc of A if I maintained B as follow up material. If I maintain only alternate item then it issues 2 pc of A but at the same time it will not check B if any shortage occur.
Pls help.

Hi,

Alternative item group
You can only define discontinuation data for a stock item or variable-size item that is not assigned to an alternative item group.
Once you have maintained discontinuation data for an item, you can no longer assign the item to an alternative item group.

Mass Maintenance of BOMs with Alternate Item Groups

We plan to create BOMs containing Alternate Item Groups (+ usage probability + priority) to cover alternative parts usage.
What is the SAP solution for Mass maintenance of BOMs with Alternate item groups?
Is it possible to use (or customize) CS20 (or another transaction) to do following tasks in Mass :
- identify the BOMs containing a specific material number (where used)
- add a new item line with a new material nbr in the BOM (with same quantity, subitems, Alternate Item Group, ...)
- when required, change the usage probability of the members of the group to set the new material usage on 100% and all other alternates usage on 0%. When not required, add the new one with 0% and don't change the existing members of the group.

Dear.
Ask your ABAP Team to write BDC or LSMW program.
This will help you.

Change Alternative Item Quantity in Production Order BOM

Hi Gurus,
I woould like to ask how can I make the Alternative item quantity to become editable. As of now, the system will calculate the percentage in the BOM and default it in the Production order.
Now I have a requirement that in the Production order Change, the user can change the quantity of the Alternative Item based on the situation with out changing the BOM. Just change in the production order. What settings do i need to change?
Thanks,
Raymond

Hi,
Can you let us know why you want the user to make the changes manually ?
Not in front of the system at the moment, but just do an Av. Check to see if you're able to get the switch if the stock situation has changed for the alternative items.
Based on what i know, the field will not be editable & there is no specific setting to make it editable.
Regards,
Vivek
