Bom selection during mrp

Hi, in oppq we are specifying the bom sel id as 01, pls explain how to see this sel id in bom for any fert material? how to link those.

Hi,
When you say you have 2 BOM's, are you referring to alternative bom's or bom usages ?
If it is BOM usage, then OS31 for ID 01 decides which BOM usage has priorty depending on the application where it is being used.
If you referring to BOM alternatives, then check the validity dates, the lot sizes of the 2 bom's. If they are identical & there is no difference between them, system by default picks the first valid alternative. But if you want to have alternative 2 picked, then you can work with production versions where you define version 1 with BOM altt. 2 & prodn version 2 with bom alt. 1. Set selection method in MRP-4 view to 2.
System will then pick bom alt 2. Alternatively you can set the BOM status to 2 at header level for bom alt - 2 as suggested above.

Vivek

BOM selection during MRP running

Hi,
   I have a question about BOM selection during MRP running...
   I have three production version and all of them are valid at the same time..I get a problem "no BOM data seletion" during MRP
running..I suspect it is due to that I have three production version and MRP didn't know take which one..Can anyone tell me
where can i config it or what's wrong with it in my situation?
   btw,BOM usage and stats are correct .so is the router data..since MRP is running well if i only have one PV..thanks..

Hi Monst,
Looking at the screenshots you uploaded, it seems that the validity of each of the production version is from 7.12.2011 to 1.12.2012.
Please check whether for Planned order no. 36659 alternative BOM no. 1 is getting selected (Since BOM selection ID is 2).
For planned order nos. 36660, 36661 and 36662, the start date is perhaps before 7.12.2011 and end date as we can see lies in the validity period of production version. Hence, neither of the alternatives of the BOM is getting selected.
For verifying the above logic, please make the BOM selection method as 3 (selection only by production version) and run the MRP. I think MRP will get terminated in this case since no BOM will be chosen for first planned order.
Just in case u need to select the BOM for planned orders, you can manually enter the production version no. in the planned order change mode.
Please tell if this helps and revert back.

Chetan.

*URGENT -Alternate BOM selection in MRP*

Dear gurus
I have an urgent requirement regarding alternate bom selection.
our scenarion is complete subcontracting and no production versions are maintained and for suppose i have a product X which has 3 alternative boms during the sales order creation iam able to select the required alternative but during the mrp run the system is selecting the alternative "1" by default.I want that during the mrp run also the system should explode the bom which i have selected during the sales order creation not the alternate "1".
please reply.

Dear Dharma
in my previous post I havent got suitable reply from my previous post so i have posted again waiting for answers.

Bom selection in mrp

Dear All,
Can anyone explaine why MRP always selects the first alternative of Bom during MRP RUN?????
Regards
Prashant

Hello Prashant Patil,
If you have more than one BOM (Alternative BOM) and all are meetings (i;e. BOM Lot Size , Bom Status, valid area and period of validity, priority for bom usage in define order of priority of Bom ), in the required settings then the first Alternative will be selected by defualt in the MRP planning run.
Hope clear to you.

PP BOM explosion during MRP

Hello all,
During MRP, BOMs for dependent assemblies are supposed to be exploded. I am running MRP in the background. Until recently, MRP is exploding only the first level BOMs such that subsequent assemblies are not exploded. Is there a setting I can check to ensure that BOM is doing a multi-level explosion. MRP set to NETCH. Thank you for your input.
Joy T.

Dear Joy,
1.check whether the BOM status is 1 for the dependent assemblies in the BOM header.
2.In case if you have used change numbers with release key for creating the BOM for those dependent assemblies,then check
in CC02 whether the release key is set.
3.Ensure that the MRP type is not ND.
Also check this thread whether this can help you,

BOM SELECTION DURING CREATION OF JOB WORK PO

Dear All,
In my scenario we are not running MRP so my problem is if i maintain two BOM for a halb material say ALT 1(for inhse prdn.) AND ALT 2(job work) .Now if i make a job work PO for this item the system by default picks the ALT1 always and i want to pick the ALT 2.There is no LOT size funda the item can anytime be produced inhse OR subcontracting.
R sehgal

Hi sehgal ,
i am giving one solution, but it works fine if you run MRP, same you can try with your case.
The right Bom can be selected by creating production version.
1. create two production versions for your HALB material, then assign your inhouse BOM for first production version, and assign Job work Bom to second production version. (MM01)
2. select Bom explosion indicator = 2 (selection by prodution version) in MRP view (MM01)
3.Then lock the first production version manually if you want do outside job work.
then create PO and check that correct BOM is selected as per your requirement.(MM01 - MRP view)
4 if you want to do inhouse prodution then unlock the first version, system will select first active version by default.
i hope this will solve your problem , otherwise ignore

Alternae BOM during MRP RUN

Dear PP Gurus,
I have a finished product for which there are 2 bom, When I run MRP for this finished product , which BOM system will consider? Is there anyway by which i can deicde which BOM it should consider?
Please help.
Thanks

Dear,
If a product contains more than one alternative BOM,try to mention this by creating different prod.versions.
You can assigne the production version in MD61 against the PIR's under schedule line tab key (in the top menu click on settings and prod version ,then you can assign the prod version which you need to pick during the MRP run),
Also selection method is maintained in Material master MRP4 view.whether the BOM needs to be selected through BOM Qty. Explosion date or Production version....
Or use BAdI MD_MODIFY_PRODVERS.
Also refer this thread,

Materials planning for Recursive BOM during MRP run

SAP Guru's,
We developed an recursive BOM as per production requirments , but we didn't know the impact of this recursive BOM during MRP run.
Pls help us how to recursive bom behaves during MRP.
Thanks & Regards
Suresh Babu.S
Bangalore

Hi,
This message was sent to us by SAP when we were having the same kind of requirement. Hope it will help you too.
Usage Probability
Material requirements planning (MRP) plans the alternative items according to usage probability.
If you use the usage probability to determine the withdrawal posting (strategy 1), the quantities are proposed according to the usage probability. You can change the proposed quantities.
An alternative item is only planned if the usage probability is at least 1%.
If the usage probability is 0%, a dependent requirement with quantity
0 is generated for the material.
The component with the quantity 0 is displayed in the planned order.
If required you can increase the quantity there.
It is possible to plan too much for alternative items, because you can enter usage probabilities that add up to more than 100%.
Hope it will help you.

Alok Tiwari

BOM selection in Prodcution Order

Hi
Need help
I have alternarnate routings ( group counter 1 and 2) and BOMs (alternate 1 and 2)
for e.g. I have assigned Alternatte BOM 1 to routing GC1 and Alternate BOM 2 to Routing GC2 using component allocation in routings.
But when I create prodcution Order and select the Routing GC 2 also system is picking BOM 1 buy default..why its happening..
Could you pl share your thoughts on this nad help me?
Rewards points will be given immediatly
BR

Hi SAM
BOM explosion during MRP is based on the lot size or validity date. *Differentiate BOM from to lot size for both the BOM's.* Ex for BOM 1 from qty may be 0 - to qty 500, for BOM 2 from may be 501- to 9999999.
Then the system will select automatically the required BOM1 or BOM 2 based on the lot size.
If you maintain Both the lot size same. The systme will automatically select the first valid BOM.
As you said Routing also selected based on the lot size.
Otherwise as senthil said used PV scenario.
Hope this is clear.

BOM explosion in MRP for non-stock material

Dear friends,
I have a non-stock(bom item category 'N') service material setup as a component in my production BOM, which during MRP run, should create a Planned order or Purchase requisition for that non-stock component. But, when I run MRP for the top-level material, it doesn't create any requirement for that service material, while all other stock material(Bom item category L), it generated dependant requirements.
Appreciate your help.
Thanks
Suri

Dear Suri,,
Please go through this.
Non-Stock Items Use this item category if you want to enter a
material that is not kept in stock before use, and that is only procured for a
specific planned order or production order.
The material is only rarely required for a custom-made product and is used
directly in the product as a purchased part.
Before you start
You can enter a non-stock item either with or without a material master. If you
enter a non-stock item without a material master, you must enter a description.
For non-stock items, you have to maintain purchasing data in the bill of material.
You enter the following materials as non-stock items because the quantities are
not updated in the material master record:
o Materials with a material type that supports configuration
o Pipeline materials, which can be taken from a pipeline at any time

Special functions
The following functions are supported for non-stock items
 You maintain purchasing data for non-stock items in the bill of material.
 In the planning run, the system generates purchase requisitions
instead of dependent requirements for components that are procured directly.
When you configure your R/3 System for MRP, you can define whether direct
procurement is triggered by the planning run or by production order management.
 Product costing processes take valuation data from the BOM item.
The system determines the release strategy on the basis of the price data you
enter. The material group is required to produce a purchase requisition.

Selection of BOM During MRP

Dear All,
I have three alternatives of BOM.The lot size and the validity period for all the boms is same.Now during MRP Run the system only selects the first alternative and plans the depending materials of that BOM.
I want to set the system in such a way that i can able to select any alternative of bom and carry out the MRP Run.
Please help me ..
Regards
Prashant

Hi Prashant,
With same valid From & To Date and Same Lot Size,
In this case system will select first BOM alternative.
If you want to choose a particular BOM then go for production version ,assuming that u r not willing to change the lot size or valid from & to date,then u lock the production versions which you dont want to show to the system before running MRP except the one which u r willing to choose.
We cant choose manually the prod.version during MRP.
Assuming that in MRP4 view of FERT material u have given option 2 in BOM slection method.
The other way is u manitain different lot size and acccordingly the production version will be selected by the system.
I hope it will help you.

Selection of Production version during MRP run

Hello experts
At present I am having 2 production versions for a material code as PV01 and MV01.
By putting validity date I am restricting correct version to be picked in MRP.
Is there any other way, for example in material master where if I maintain the production version, then MRP should pick that only.
Please suggest the best way.
Regards
Pradipta Sahoo

Dear Pradipata,
If you are having more than one production version for a material for the same Lot size and validity
dates,and if you have given BOM selection method as 2 in MRP4 view,then always the system picks up
the first production version defaultly.
If you want the system to pick up the second production version in that case means,you have to lock
the first production in MM02 or C223.
Check and revert back.

BOM selection in the MRP

Hello Gurus
   when MRP runs , what is the process of BOM selection. Are there any user exits to control the BOM selection.

Dear Vidyadhar Reddy,
For BOM selection you will assign the selection ID in T Code OPPQ --> under planning run -->
BOM/Routing selection.Say suppose if you are assigning an ID 01and for this ID you can have many
options using priority.
Say SelID     SelPr     Usage     Usage text
        01     1     1     Production
     2     3     Universal
     3     2     Engineering/design
So in This case the system seraches for a BOM with usage 1 production,if there's no BOM with this
usage for production,then it seraches the BOM with the next priority say universal BOM and then the
next priority for Engineering Design BOM.
This priority can be configured as per your business requirement in T Code OS31.
So the above is from configuration side and from the front end,
1. Using BOM status - Active(01) and Inactive(02).
2.Using Lot size and validity dates you can control the selection.
So check with this and revert back still if you have more queries.

Mangalraj.S

Alternative BOM problem in MRP run

Hello Experts,
We have two BOM for one material.Now I want to use BOM-1 for MRP run & BOM-2 for subcontracting.I have maintined following settings.
1) Production version.
2) BOM explosion selection method in MRP4 -2
3) Assign PV in inforecord for subcontracting.
4) Assign PV in MD61 in schedule line .
But when I run MRP it still consider subcontracting BOM.Have I missed any setting?
Kindly guide.Thanks you.

Hi, Follow the below process,
1.Enter the BOM selection method as 2 in the MRP4 view of the material master.
2.In case if you have not assigned the production version in MD61 against the PIR's under schedule line
tab key (in the top menu click on settings and prod version ,then you can assign the prod version which
you need to pick during the MRP run),the system always picksup the first production version during
MRP run even if all the prod versions contains the same validity dates and lot sizes.
3.If you are not willing to assign the prod version in MD61 ,but the system should consider the second
prod version for MRP run means,then set the locked status for the first prod.version.
4.When run MRP via MD02 or MD50 in the simulation mode.(i.e w/o giving tick in simulation mode).
Click on Save,You will get a pop screen,
Now click on the continue icon, Then go to Plaining Results: Individual lines screen.where you will get Plan order on which when double click you will get pop screen below,where you have Planned order no,quantity,plant,storage location,and version.
Now here you can select the required version,and it will become firmed. This BOM will be used in the order now. Try it.

No PR during MRP

There are no PR's getting generated for some of the materials despite the requirement, no stock availability and proper MRP and Procurement type in material master.
The problem is that all these materials that are created with LSMW. What could be be possible error in the LSMW. I have checked for MRP and purchasing fields and they seem fine

Hi kannan,
pls let us know , whether
the Dependent Requirements from the Header material are being passed down to the component and Pur Req not getting generated
or
Dependent Requirements itself from the Header material are not passed down the level.
Have u checked the BOM explosion in CS11 ? if it is getting exploded here and not during MRP pls check the foll. the possible reasons for the BOM not getting exploded
1. BOM status
2. BOM Selection ID
3. Explosion type -
4. Relevant to production Indicator - BOM Component details screen
5.BOM validity - pls try for different reqmt dates and check whether BOM is getting exploded

Sheik
