BOM explosion while MRP run

hi all
I have a FERT for which raw materials are assigned in the BOM. but while running MRP, the BOM is not being exploded and the list doesnt show the raw materials.
I have checked in the Overall maintenance of the plant parameters in MRP in SPRO and the required paramenters are maintained.The scenario is MTS - strategy 10.but still the BOM is not exploded.
Could anyone solve my query
Thank you in advance
chandra

Hi Chandra,
Could you please check if there was an exception message "50 or 52"? If so then it can be beacuse for the BOM explosion date system is not able to get a BOM.
If there were no exception messages then check in MRP4 view of the FERT material for dependent requirement defination. This should be blank.
Hope this helps..

Prasobh

BOM Explosion IN MRP RUN

When I run MRP BOM Explosion doesnot take place for certain F parts.This is REM scenario.Planning strategy is 40.I have already checked Planning file entries.
It is OK.Please guide.

Hi,
Pl. check in T.code oppq (plant parameters), if you have mentioned the BOM explosion ID. or in T.code oppq (mrp group).
Also check in the material master, mrp 4 view,
the bom selection id.
whether it is based on lot size or based on production version.
You can cross check using t.code cs11 or cs12 (bom explosion).

BOM Explosion in MRP runs for sub-contracting PO

Hello Experts,
We have sub- contracting Purchase order in business scenario.
Subcontracting PO is required to be considered as demand for MRP. As I have checked PO is showing in MD04, after MRP run using transaction code
MD02 subcontracting BOM not exploding.
Sub contacting PO raised on “X” procurement type material, PR is required on BOM item “F” Procurement type
Please suggest what all special setting is required as master data & configuration data.
Thanks in advance!!!

Hi,
In the header or parent material (the material that is being produced bu your subcontractor) you have to maintain the following data:
Procurement type = F
Special Proc Type = 30
MRP Type = PD
Lot Size, Minimum Lot Size, Rounding Value: Enter what is convinient for your business.
Be sure you have a BOM (CS01)
Create a Production version indicating the BOM (C223)
Enter Selection Method 3 in the MRP4 view of the material master
Create an Info Record (type Subcontracting).. (ME11)
Create a Source List (ME01)
Run the MRP and check MD04
Kind Regards,
Mariano

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.

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.

Creation of production order while mrp run

hi
ppgurus
can any body explain how to create a production order by mrp run

in which setting this setting to be done in REM

While MRp run which time is taken into consideration(from PIR or from MM)

Hi PP gurus,
When we run MRP which time is taken into consideration for a bought out material :
From Material Master ( Planned delivery time)
or
From Purchase Info record : the delivery time mentioned in the PIR ..
In my case the MRp run is showing 2 different results in different systems for the same material.
Also please let me know that if there is any priority that can be set in SPRO for picking up the time while MRP run and what takes priority and when.

Hi!,
If you are getting two different values after MRP in two different systems then please check:
1. whether any other info record exist for the same material in any of the system.
2. Have you maintained source list in both the systems for the material. How many sources are defined in the source list and in what sequence. If you have not maintained a quota arrangement then system will take first line item of the source list.
You can't set the priority for the planned delivery time but you can set whether system should take planned delivery time from info record or not in IMG setting Material Management > Consumption based Planning > Planning > Procurement Proposals > Define External Procurement. To use the planned delivery time from info record you must maintain a source list for that material with same vendor. Also make that source as MRP relevant.

BOM Explosion for MRP Area

Dear Expert,
I have doubt regarding BOM explosion for MRP Area. This doubt is triggered when performing MD01, as result I do not find the dependent requirement in MD04 for my FG. I have maintained the BOM through CS61 and MRP area for all component, I understand that only component level system is taking into account MRP area (storage location). FYI before maintaining all components to MRP area, the BOM explosion was successful exploded. Your advice is appreciated.
Best regards,
Mahnansa

Dear,
Please check the Explosion control in Customizing, Transaction OMIW.
Try to explode the BOM in CS11 , CS12 or CS13 if it is working there in curret date then chack the planning file entry in MD21.
You need to convert the planning file entery at MRP area in OM0F.
Also note the dependent requirement is not generated in the corresponding MRP area to which the production storage location in the material master has been not assigned for the data of the MRP area.

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.

Issue with BOM Status in MRP Run

Dear All,
I have a BOM structure and BOM status as attached below.
In this case, system is generating the PR's for all three components correctly while i run MRP (MD51). But when i convert planned order to production order for "Assembly" & "BOM", it is coping the components for Assembly correctly but not for "BOM".
If i maintain the BOM status as "4" for "BOM", then the components are copied into Production Order but i am getting double PR's as the BOM is exploding two times.
As per my requirement BOM should be exploded only one time ie. for "Assembly" and component should be come in Planned order for "BOM".
Please tell me where is the problem..
Regards,
Rao

Dear Rao,
assembly and Bom have the same type of production order?
In the production order type which application is contained? PP01?
You should check the explosion setting in the profile order and the setting of application of the Bom.
if you can send me screen shot of the planned order of the Bom (components details).
Thanks
Daniele

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,

Sales order while MRP run

Hello friends;
My requirement is such that when i run mrp in MD02, system should not consider those sales order that are planned in previous MRP run. System should consider new sales orders that are created after MRP run.
Waiting for reply.
Thanks.

Hi,
One solution is go for individual Sales Order/Line Item MRP run using T.code MD50.
But I can't understand problem with use of MD02.If Receipt element(Plan order)is there which contains the Account Assignment of that Sales Order line Item then I don't think system will replan for same Sales Order Line item.

Sample steps to setup BOM explosion in MRP

Hi everyone,
I am one of those unlucky folks that can't seem to get a simple BOM with FERT to explode HALB component within in MD02. I have spent two days reading every post about this common issue found over the Internet as far as 2007 and also read the SAP note 13023. I tried every suggestion to troubleshoot without success.
In my environment, I am using a clean IDES with standard SAP configuration, meaning no changes were done on it. As faced by others before, the BOM component just won't explode. I have even blank the days in MRP2 not entirely sure if my way of troubleshooting make sense. For simplicity, I have input a safety stock value to trigger the FERT within MD02.
Rather than I ask the same question again about where it might have gone wrong, may I know if anyone here can send or point me to a sample few steps guide or screenshots for the FERT and HALB MRP1 - 4 views and the BOM itself (1 material with 1 component)? I can then simulate the results using my IDES and move on from there.
Asking in this forum is actually my last attempt. My apologies to forum administrator for posting a request instead of something helpful to the community.
Thanks.
D.B.

Hello DB
The most common cause for a missing BOM explosion is the validity.
On transaction OPPQ, on tab BOM explosion, you can determine which date will be used for the BOM explosion. You should make sure that your BOM is valid on this date. You can try to create your BOM with a validity in the past, in order to guarantee that it will be exploded.
Another common reason is the setting selection method on MRP4. If it is set to 3, the BOM will be only exploded if there is a production version.

Labels Batch No allocation in Purchase requistion while MRP Run

Dear Experts,
While running the MRP PR are generated for labels as per BOM to purchase department, but in our case labels are purchased by purchase department, So can i give the batch number to purchase department through PR, so that they can print the labels as per the batch number mentioned in PR.
Regards,
Phalgun Patel

Dear Phalgun,
Thanks for your appreciations.
In PR you can maintain texts at Header level or at Item level. Go to transaction ME52N - Change PR & Enter your required PR no.
Now if you want to maintain some common texts for your complete PR then enter Header Texts. For that you can click on the Expand Header tab below the bucket trolley or press Ctrl+F2. Texts tab will be opened. Now you can enter the texts in the field of Header texts.
If you want to enter the texts specific to any Items, then you have to enter texts at Item level. For that you have to select that item and click on the Collapse Item Details or press Ctrl+F7. There also you can select the individual items from drop down which are present in the PR. Select Texts tab and there you can enter the required texts, in your case you can enter the required Batch No. for those items. Here you have different options like item texts, Item Note, Delivery texts etc. etc. You have to double click on those options where you want to enter the texts.
Further for your information, to copy those texts in to PO, you need to do the customizing with the help of your MM Consultant. Also you can print those texts on your output.
Hope now this will be clear to you.

Hiren Ramani

Bom explosion after MRP (variant configuration)

Hi Experts,
I'm facing a problem here, for unknow undentified reason until now, after I run the MD50 with a configuration material, I cannot get a explosion of the itens. This is happening in 4 cases here and I cannot get any good result, I check dependencies rules and everything and no success
Does anyone know waht can I do?
regards
Oliver

HI,
If a BOM is not exploded possible reasons 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.
