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.
Regards,
Suhas

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

DTW Template for Alternative Items

Hi Experts,
Can someone tell me which template do we use for importing Alternative Items ?
Thanks & regards

Hello
There are other cases where that is also ... such as Profit Center ...
There are other alternatives that are not recommended by SAP to perform these operations, which are the responsibility of the person who performs (DTS)

Can we run MRP for perticular ITEMS or Can we run MRP on MRP Group wise

Dear Friends,
Out of all Material masters MRP should be run on some meterial.
Is there any way to run MRP on perticular 1 MRP Group ?
Is there any way to run MRP on selected MATERILS ?
Waiting for ur help.
Thanks...
Yogesh.

Hi Yogesh,
It is possible with the enhancement -> M61X0001, take the help of your abaper & he / she would implement your logic.
In customizing, SPRO - Production - MRP - Planning - User Exit: Mtl selection for planning run define a key & assign it in MD01 initial screen.

Mrp FOR VERP item

HI all
For verp material I set reorder planing(VB) MRP type .
but by using MD01/MD02 selecting (purchase requ.) type after runing
planed order generated instead of MRP PR

Hi,
make sure that you are using create PR indicator as 1Purchase requisitions or
2 Purchase requisitions in opening period on intial screen of MD01/02 .if it correct then go to spro->MM->consumption based planing ->mrp groups check
1.Carry Out Overall Maintenance of Plant Parameters
2.Carry Out Overall Maintenance of MRP Groups - check MRP parameter for plant you are using.
3.Define MRP Group for Each Material Type -check materialmtype you are using.

How to run MRP for BOM as well as ROL items

We have only one plant. I want to run MRP for BOM items as well as ROL items. MRP can be run plant wise thru tcode MD01. I want to run mrp for only ROL items.
Please suggest

As I understand for Quartz, I think you should create a security subject for it in your code. I guess the background tasks in Quartz work in separate threads. It is not recommended in EJB application. you can use EJB timer service instead.

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).

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.

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.

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,

PR and PO should be display in IWBK report for stock item.

Hi Exterts,
Our client requirement is to display PR and PO number in IWBK report for stock item as well.
I know PR and PO can be display in IWBK report for non-stock item but how we can display PR and PO for stock item,as PR is generated through MRP for stock item.
Please share your ideas on this.
Regards
Vishu

Vishu,
In typical MRP settings you "procure to stock" not "procure to order".
This means that there is no direct link between the PM/CS orders and any PR/POs created via MRP.
Subsequently you will not be able to show this data in IWBK.
However, we are currently designing a customer-specific report similar to IWBK that also counts the number of open POs for a given material on a PM/CS work order. The user can then navigate to ME2M (PO list) or MD04 (stock requirements list) to get further details.

Alternative Item n sales

hi all,
we have 4 materials. say A,B, C & D. all are common.
my scenario is as follows :
out of four i want to keep A as a main materials and it will act as a alternative item for remaining B, C & D.
Though sales requirement generate on B, C & D it will automatically pass on "A" w r t stock availability.
in sale order i have check ALternative to item in sales "A" tab. but it is only for quotation and it is not useful for requirement generation.
please advise for alternative item task in sales transaction
thanks in advance

hi Sir,
thanks for the reply.
we are using number of Pumps as a one of component of assembly.
there a number of pumps we are purchasing. child parts of these pumps are same.
so i have 4 pumps. in these 4 pumps at lease 70 % child parts are same.
so to avoid inventory i am planning to implement common / alternative materials task.
in PP module it is possible but in Sales i am not find alternative item field available.
i am implementing this scenario to avoid unnecessary inventory.

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.

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.
