Alternative Items in MRP

Hi,
Is SAP business one will consider alternative items in MRP Wizard for 9.1 PL05? If no, will there any work around solution? Please advise.
Anna

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.

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.

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 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)

Mario

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

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 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

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.

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.

Alternate Item In MRP

As one of customer is a Electronic manufacturing using standard SAP Business One in 2007 B patch 18 . As customer is very much unhappy due to the Alternate item that is NOT coming in MRP module.
Please look into it and advise
Thanks

Hi
Currently this is missing functionality. As deepak sadi u can use Alternative items in Marketing doc's ..if u want this functionality to add in B1 then u can raise a thread in this forum :

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.

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

About Alternative item usage prob value(percent) function

Hi guys:
How does Alternative item usage prob value(percent) impact which alternative item Production order uses.

Kevin,
Could you please look at the stock situation of material "A" and "B".
It looks like from your posting that "Stock of material A" is having shortage of quantity w.r.t to requirement quantity for the production order that is the reason it has pulled in material "B" in production order.
Key points to note
Alternative item: strategy
This value defines how items in an alternative group are selected for withdrawal postings.This strategy is ignored in material requirements planning (MRP).
Use
The withdrawal posting for the reservation in the production order can be selected as follows:
According to usage probability (manual changes possible)
For all items that you want to reserve, enter:
 - Strategy (value 1 or no entry)
 - Priority (only influences how materials are sorted)
 - Usage probability
Withdrawal if 100% availability
For all items that you want to reserve, enter:
 - Strategy (value 2)
 - Priority (If you do not enter a priority, the system checks the items in the sequence in which they are transferred to the availability check).
 - Usage probability
Usage probability in % (alternative item)
Percentage probability that a material will be used in the assembly.
Use
The usage probability is always taken into account for requirements planning.
Maintain selected usage probability
Requirements planning for alternative items is based on the usage probability.
Quantities are suggested based on the usage probability for the withdrawal posting according to strategy 1. You can plan in excess for the alternative items since the usage probability is not limited to 100%. You can change the proposed quantities. Maintain no usage probability If you do not enter a usage probability, the alternative item just serves as information that can be evaluated, for example, in a situation with a missing part.
You receive a warning since dependent requirements with 0 as quantity are created.
But if the strategy is "2" - "100% check" then the material which fullfills the requirement will be reserved for the production order after availability check.
So In your case change the strategy to "1" so that reservation is carried out based on the probability
Hope this helps....Reward your points,
Regards,
Prasobh

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.

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.

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.

Vivek

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
