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.

BOM selection at the time of confirmtion

Dear Experts,
My client has requirement that BOM should be selected at the time of confirmation if there are multiple BOM's are available for the same material.Is it possible ??.
Edited by: manjit_pune on Mar 7, 2012 10:07 AM

Hello Manjit,
As a SAP fucntion, BOM should be selected/exploded at the time of MRP so that SAP would be in position to plan the components accordingly. What the reason or benefit of selecting relevant BOM at the time of confirmation ??
In any case, this function is not possible in standard SAP.

Manual BOM selection at the time of order creation

Dear Experts,
Could you help me to understand if there is any provision to select BOM by user at the time of order creation without the help of production version.Is there any configuration required to make BOM selected manually.
Regards,
Krishna Mohan

Hi karishna,
Please go to T-code OPL8 and in production version use( 1 )Manual selection of production version. Then user can select manually instead of automatic selection.

Alt BOM Selection at the time of order creation

Hi Friends,
For one of our FERT We Have 4 Alt BOMS and Fore Production Lines
My requirement here is while creating The Production Order In co01 I Need to select The Required Alt BOM. How to configure this spro
However the System Is asking for The Production Lines(as Pop UP Massage)
Suggestu2026u2026
Hari

Hi,
For that you need to maintain the production Version in material master MRP4 view in that maintain all your BOM and routing.
Then MRP4 view of material master there is option selection method here you need to select 3-Selection only by production version.
After that in OPL8 for your order type and plant maintain
Production version-1 Manual selection of production version
Please try and come back.

Selection Of BOM & Routing at the time of production order creation

Hi guys,
Please clarify how i can go about for the following mentioned scenario
I have one Master BOM(Finished Product Level) & alternative BOMs for that,similarly i have one Master Routing & alternate routings for the same finished product
At the time of production order creation is it possible for me to choose one of the BOMs & One of the routings of that particular finished product without creating a production version?
Awaiting for a quick response
Vijai

Hi vijai prasad shanmugam ,
In the material master MRP-4 view under the BOM selection you can maintain on what fatcors you want the BOM to be selected Viz. Selection by order quant.,Selection by explosion date.Selection by production version etc.
As far as the master recipe is concerned ........ I guess that if there are more than one valid master recipe maintained then SAP will prompt to select the one manually.........
But it the standard practice to maintain the production version ....... for the similar situation to the one that you have mentioned.
Please Let me know if I can help you in any way regarding this........
Please reward the points......... in you find the ans helpful.....
Thanks

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.

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.
Regards,
Chetan.

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

To run the mrp for the selected 3 or 4 materials together in plant

Hello guys,
Is it possible to run the mrp in a plant for selected 3 or 4 finished material together?
As far as my knowledge is concerned its not possible.In scope of planning or mrp area you can group couple of plants or storage locations but not the materials.Am i right?

Hi,
You can use MRP user exit (M61X0001), where you can define user exit key for MRP type, MRP controller or External procurement key. So you can group these materials into one MRP controller and then you can use that user exit key to run MRP for that MRP controller materials.
Thanks,

Exception Error Message (52) No Bom selected

Hi
a) I have created a simple 2 layer BOM ( level 0,1,2)
When I execute MRP run, I get the expection message - NO BOM SELECTED ( 52) for the 2nd level material.
Please advise.
Parthasarathy

Hi All,
Checked following before I posted this question and there are no problems with them:
BOM usage: 1
BOM status: 1
Valid from: September 2011
Lot Size for BOM and routing: 1
No deletion flags are turned on for BOM, material and components
BOM item Production relevant: yes
BOM materials are of same plant
Rerun MRP: yes... does not help. quantity of VSEB and plan orders can change but the message 52 still remains and does not explode.
This is only happening in my QAS system... production system with same material and information is ok.

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.

Exception message"no BOM selected"

Hi Experts,
In what circumstances is the above error message i.e. "no BOM selected" thrown ? When I am running MD02 for a FG, I am getting this message. This FG has only one SFG as it's component in the BOM. Production version for FG exists. The SFG has no BOM/production version. How can i avoid this message and what all does it imply? Please suggest.
Regards
Sm.

The possible reasons for " No BOM Selected " Exception M,essage 52 could be
1. Validity period of BOM
2. BOM Status (should be active for MRP.)
3. BOM Components should be relevant to production.
4. Check whether you have defined the selection ID for the priority of BOM Usage in SPRO define order of priority of
BOM Usage.
Thanks,

Bom Selection

Hi Friends
I am working on a Long Term Planning Scenario, while simulating the client will use various BOMs to check the costing during Annual Planning run and also for Planning run for a Quarter, how can I select the BOM as required during LTP-MRP Run? Also plz let me how to configure the BOM selection ID??
Jade

Hi,
BOM selection will be done by automatically, manually not possible. In material master MRP4 view BOM selection option given by,
1. Lot size
2. Date
3. By production version
4. Only by prod version.
System will select according to that only.
Before configuring BOM selection ID, we have to configure Order of priority b ytcode OS31. In this create selection ID no by priority wise respect to BOM usage.
Use this BOM selection ID in BOM application as required.

Dharma
