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 Item with %0 still planned with qty 0 by the MRP

Can somebody explain me why the MRP manage also the Alternative Item MAterial with % 0.
Why the MRP do it?
There is any setting that I can do in SPRO to fix it, or better to let the MRP recognize the item in alternative and check the usage probability if it 0 what I expect is that I do not find into my planned order the material with % 0 but only the one with % 100.
Thanks

There's a good reason that it is in the planned order, and later in the production order with quantity 0.
100% is for planning, meaning that in MRP this is the material that will be procured.
But now, in the ProdOrd, when you perform an availability check and there isn't enough of it, the system will look for available stock in the alternative item, and commit it if so. This is the whole point.
For that, and for the information that this material has alternatives, the system is showing the alternative materials with quantity 0 in the order. (if I remember right they all have the same line item number)

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,
[Kindly check this link |http://help.sap.com/saphelp_47x200/helpdata/en/a0/1016bd4c8311d189520000e829fbbd/frameset.htm] which has information of the below.
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.

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.
Regards

Alternative item sel on the basis of stock -2 items at a time by automatic

we r dealing presently with alternative item selection at the time of confirmation screen MFBF.we are thinking to make alt group in the bom by automatic sel with strategy 2 for all items so that on the basis of stock availability component will get selected.but my question is suppose we have below alt items for 1 perticular bom and at the time of confirmation we required 20 or more quantity ?how i can do automatic confirmation?
because by maintaining strategy 2 for auto alt sel only one component will get selected at a time.
220229-10 kg
220222-10 kg
220870-10 kg
220901-10 kg

Dear,
With stg 2, system will selcet as per the priority and usage probability. If you use 100% usage probility, then system will check only first item to satisfy all 100% requirement, and other line items will not be considered, this is what i told in the first communication. Hence you need to change the probability in order change material overview screen after running availability check, system will show as below in CO02 component details screen
Item -1 usage probability -100
Requrement qty --10
Committed qty----7
Issue qty----
0
Original qty----
10em 1
Item -2 usage probability -0
Requrement qty --10
Committed qty----2
Issue qty----
0
Original qty----
10
Item -3 usage probability -0
Requrement qty --10
Committed qty----3
Issue qty----
0
Original qty----
10em 1
Item -4 usage probability -0
Requrement qty --10
Committed qty----4
Issue qty----
0
Original qty----
10
Since you know the commitment qty now, You change it to
Item -1 usage probability -100
Requrement qty --10
Committed qty----7
Issue qty----
0
Original qty----
7
Item -2 usage probability -100
Requrement qty --2
Committed qty----2
Issue qty----
0
Original qty----
2
Item -3 usage probability -100
Requrement qty --1
Committed qty----3
Issue qty----
0
Original qty----
1
Item -4 usage probability -0
Requrement qty --10
Committed qty----4
Issue qty----
0
Original qty----
10
Now if you do the confirmation...system will show the requirement qty as below
item 1 req qty = 7
item 2 req qty = 2
item 3 req qty = 1
item 4 req qty = 0
Now it need not be corrected during confirmation.
I hope you got the point. If not please give example as i have given so that we can understand...any other automation I think not possible

How to manage the alternative / interchangeable material in a BOM

Dear Sir ,
firstly i appreciate any effor to handle this problem ...
secondly excuse me for long problem description and details .
thirdly consider it as a challenge for you .
Suppose we have a (Finished Goods -> M1,M2) and (Raw Materials -> x1, x2 , x3 , y1 , y2 ) , Suppose the BOMs are :
M1—( x1 , x3 ) , M2—( x1 , x2 ).
- We receive Change notes type ( A , B , or C ) from the designer :
Type (A) : For M1 that x1 will be replaced by y1 --> (Stop use of x1 for M1)
or type (B) : For M2 that y1 will be Alternative for x2. (It mean that we can use both of x2 & y1 alternatively)
or Type (C) : For M2 that x1 used qty in the BOM will be changed (change in Qty.)
Find the flow chart in order to know the requirements of the business .
So how i can control this bussines for each type (A,B,C) ?

dear,
all alternative at SAP system can you handle by many method ,
1- if you didn't use this item again related to all BOM you can use
follow up material method .
you can use it at master data tap "mrp4" put discontinue indicator 1 also, put the follow up material.
after that go to specified BOM and link the follow up material item by follow up group,
2- if you will use two alternative item parallel you can use
alt.item method :
you make alt. item related to 2 item at one BOM , it will depend to strategy method
3- if you know the date that the old material will sufficient your production ,you can use the
changing note method
you will create changing note and after that apply it at the BOM .
thx.

Alternative items during MRP run

Hi,
I have seen discussion on alternative items in BOM. Thanks for all for sharing your knowledge. I knew alternative items will be choosen while creating / release of production order (material availability check)
Requirement:
For material A, I am using component B as priority 1 and component C as priority 2.
During MRP run, system needs to CHECK component B first. If stock is not available for component B then system need to consider component C automatically. It should not create any planned order for component B.
Is it possible, system will check automatically alternate items during MRP run? if so kindly let me know the logic.
If not, is there is any user exit. Customer is asking this facility. Its his basic requirement.
Kindly give your suggestions....
Regards / US

Hi.
I might have typed it wrong, I think the right one is called DIMP.
As far as I know you don't have to purchase it. In the past those extensions were known as Industry Solutions, in this case Automotive and A&D.
Before you go to this complexity for interchangeable materials functionality in MRP, I recommend that you have a design review with your customer, to strengthen the point that if two materials are the same for all usage purposes, but only differ, let's say, in the source (different manufacturer). for that in SAP we would define ONLY ONE material number, with additional manufacturer part number info, and in some cases with a classified batch.

Fixed quantity not supported for alternative items

Hi dears,
I was trying to configure in a Bill of Material a group of components marked together as "Alternative item", having the Fixed quantity indicator set (so the quantity is not in proportioned with the order quantity).
However, when I do this action I have the error message no. 29485 "Fixed quantity not supported for alternative items", because a fixed quantity is not allowed for alternative items.
Leaving out the fact that I don't understand for which kind of logic this should be done, do you know if there is any solution to achive the same result (use alternative item and each of them should be with fixed quantity despite th eorder quantity)?
Thanks and regards,
Giovanni

In standard cost estimate the cost of alternative items flowing in full

Hi,
when i calculate the standard cost estimate in repetitiv manufacturing the
complete cost of all alternative items in alternative group is flowing to it.
how to restrict it
thanks in advance
regards
madan

Solution
1. make one of the materail in BOM, as not releavent to costing....depeding on which alternative is better to get the correct std cost
2. Use stargergy 1 usage probnability may be 50% and 50% for alternatives...depending on usage of that material.

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.

Alternative items to be selected at the time of confirmation

I maintain alternative items by using alt group in the bom.But while confirmation of parent material,the material which has the first priority is coming.but if i want to choose different material then what should i do?
first thing:
I dont want to touch bom as user dont have authorization for the same.
second thing:
can it is possible alt materials will be selected on the basis of stock avl in sto loc

I know that on the basis of priority ,i can select the required component for confirmation but please tell me how i can select material on the basis of stock available.because suppose in bom i maintained 110022 material as first prioriry and i want to select 110023 at the time of confirmation .
I know user can change the component 110022 to 110023 on confirmation screen manually .
also if we dont want user to change this manually .
Is there any solution that all alt items will appear on the screen and user can choose as per requirement.

Alternative item selection at the time of confirmation.

Hi, please suggest how to maintain alternative items and also how to choose alt items at the time of confirmation of specific material.

Hi,
Alternative item has to be maintained in respective BOMs.
Give the same item no in the BOM for the alternates.
Double click on one of the alternate item, the header data for the item will appear.
In the basic data Tab, enter the ALTITEM GRP value it can be any number or character.
CLick on the arrow button that will appear after entering the alternate item.
Give the Priority, Strategy & usage probability. BAsed on these values the alternate item is selected during BOM explosion.
The alternate item group value should be same for both the alternate items.
For further details refer

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

HKV...

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
