BOM Explosion/dependant requirements

Dear All,
I have a concern regarding the "MRP 4" view in MM.
BOM/Explosion
Individual / Collective requirements
"MRP 3" view
Availability Check
Availability Check (Daily / Individual)
I would like to know the effect of these settings clearly with an example please.
Thank you in advance

Hi,
1. The Individual Collective indicator 1/2 indicates how to club the dependent requirements either Individula Processing or Collective Processing.
This is generally used in MTO Scenario.
Here, For eg., you have 2 FERT Materials, in that 1 component say xyz is same.
If you want to club the requiremnts for for xyz for both the sales orders then you need to select 2.
By defult system will create PurReq for xyz as Sales Order/Customer Specific.
2. Now the Availability check:
Specifies whether and how the system checks availability and generates requirements for materials planning.
The availability check can be carried out in MRP for the depedendent requirements. This means that the availability check can directly check whether sufficient material is available for the production of the assembly. The availability check is initiated from planned order processing. It is not carried out automatically in the planning run for each requirement of an assembly.
Checking Group and Checking Rule clubbed together forms the Checking control..
Hope this helps..
Regards,
Siva

Bom Explosion/Dependent requirement

Dear Gurus,
In Material Master in MRP4 view there is one field under Bom Explosion/Dependent requirement individual/coll. when we select indicator 1 it generates requirements individually and when we assign indicator as 2 system cumulate the requirement,but if we keep that field blank i.e. individual and collective requirement how system decide the priority for individual and collective requirement.How system behaves in that condition.
With Regards.

I am asking about ROH BOM components.
Dear ,
Yes I know, If you maintain collective indicator for header material, IF the ROH as blank in indiv/collective indicator, ROh material behave like collective reqmt
If you maintain individual indicator for header material, IF the ROH as blank in indiv/collective indicator, ROH material behave like individual reqmt

Which bom explosion/dependent req. used when creating order

a material's production version ( MRP4 in material master) has 2 or more versions and all versions are valid. when creating a production order, which version will the system take?

Dear,
If you are creating the production order manually through CO01,if your order type dependent parameter for the order type in OPL8
is having manual selection of prod version means the system will give the pop up to select the production version.
If it's an automatic selection means the system by default will pick the first production version,if you are having more than 1
production version for same lot size and validity.
Check and revert.

Planning of Dependent Requirements for BOM Components in Make to Order scen

Hi Friends - I want to execute a full cycle Make to Stock Scenario with Materials planning using MRP.
The scenario will include BOM Components with Routing.
The process flow I want to execute -
1. Create a Sales Order for a Finished Product (Product should have a BOM for Production)
2. Do the product Materials Planning for the Sales Order through MD50
3. Get all the dependent material requirements (both for products as Planned Order and also for BOM Components - all the BOM components should also be planned)
4. Convert Planned Order for Product to Production Order
5. Convert Planned Orders for BOM components to Purchase Requisition
6. Confirm Production Order
To execute this I have done the following
1. I have created a Material Master data for Finished Product (FERT).
2. I have assigned Item Category Group - NORM, and General Item Category group as NORM
3. I have assigned MRP Type PD in MRP 1 View and Strategy Group 20 (Make to Order Production) in MRP 3 View.
4. Now created a Universal (Type 3) BOM for the product with one material component.
5. Now also created a Routing for the Material with two operations having PP01 a control key.
6. Now created a standard sales order for the product.
7. Executed the MD50 for the Sales Order Item.
Now where do I find the BOM components for this material in the Sales Order?
After executing the planning Run MD50 I am only getting the requirements for Product only. I can't see any dependent requirements for the BOM components.
How do I make sure that the BOM components are also planned while the product is planned?
I have checked the component Stock Requirement List - there are no requirements generated from the Sales Order Product BOM.
Pls help me on this. How to do this so that the raw material components are also planned?
Thanks
Purnendu

Hi Dhaval, Sandeep, Ashok - Thanks a lot for your replies.
I have checked the Planned Order Created through Planning Run.
If I click on the Components Tab I am getting following message
No material components were determined
Message no. 61027
Diagnosis
Until now, no BOM explosion has been carried out or no BOM has been created for this material yet.
Procedure
Either explode the bill of material for this material, or
create the components manually by processing the planned order in change mode.
If I try to explode the BOM through Header Menu - Edit> Explode BOM
I am getting the same message.
If I click on the Bill of Material Tab - I am getting the same above messge.
Ashok - I have tried both the Selection Method -
Nil - Selection by Order Quant.
1 - Selection by Explosion Date
But with no effect.
Waiting for your advice.
Thanks and warm regards
Purnendu

MRP RUN- KIT BOM explosion not working

We setup one layer BOM’s for our maintenance KITs as parent material and components as child material. For example KIT is TS10000-K1 and components are TS10001, TS10002 etc setup as next layer with in the BOM. Both KITS and components are defined as material types ERSA (Spare parts). These one layers BOMs are setup as production BOMs and expected to create purchase requisitions for KITS and components by exploding BOMs during MRP runs. We use purchase requisitions and convert them into POs to procure both KITS and components. We DO NOT USE Panned orders and Production orders.
The safety stocks / reorder point are considered as demand for KITS and components as we do not have any external demand for KITS and components.
MRP run is creating purchase requisitions automatically for both KITS and components as per safety stocks and reorder point defined in MRP Views of Material Master. This is working as expected.
The issue is: KIT BOM’s are not exploding to generate purchase requisitions for the dependent components of KIT BOM. Please suggest the way to resolve this issue.
Split valuation: Also we plan to use split valued KITS with both new and refurbished. So we need BOM explosion for split valued KITS
also (after the 1st issue is resolved).
I verified the following items to make sure the required configuration and data setup is defined correctly.
1) Planning file activated Plant - OMDU
2) Executed MRP run with Total Planning - MDBT and MD02 (single item, multiple levels)
3) BOM explosion for MRP activated- OS23
4) MRP type in MRP1 view- PD and VB (I tried both separately but BOM is not exploding).
5) Procurement type “F” (MRP 2 view) and lot size “EX”
6) Planning strategy in MRP 3 view (tested w/o planning strategy and with strategies 10 and 40. But BOM is not exploded)
7) BOM status and usage (status is active and usage is for production-CS02 and OS20)
8) BOM Validity date (Valid)
9) BOM structure in CS12 (BOM is exploding in CS11)
10) Availability check
11) Selection of BON ID to have BOM usage indicator assign (OS31).
12) No alternate BOMs or production versions or work scheduling view are used.
Please review the above 2 issues and suggest any workable solution. Thanks in advance!
NOTE: I extensively used MRP with multi-level BOM explosion in my earlier projects without any issue. However the above issue is a bit strange why one layer BOM is not exploded in this case.
Regards
Srini

Hi
Thanks for your response. I reviewed all SAP notes and none of them are applicable to my scenario.
1808396 - BOM changes not considered by MRP: I have not changed BOMs.
1781324 - MD11: Valid BOM alternative is not found. We do not have alternative BOMs.
1791009 - No BOM explosion after changing production version: We am not using production versions.
Our Material KITS are PM spare assemblies set up as BOMs and consists of individual spare parts as components. We are creating purchase requisitions and not planned orders. We are not using PP functionality/Production orders.
MRP is generating purchase requisitions for KITS and components as per ROP and safety stocks. In other words it is working as expected. The issue is BOMs which are parent assemblies are not exploding to the next lower level components.
Please note that I am not getting any error messages when MRP is executed.

Srini.

Setting nedded for creation of Planned Order for Dependent Requirement.

Hi PP Gurus,
I have a one material for which I m running MRP which have three Components.
I m using strategy 10 for FG and SFG also.
When I m running MRP for FG the system is creation planned order for FG, but not for SFG even though no stock available for them.
I m using lot size EX for all SFG.
Please Help.
Thanks in Advance.

Dear ,
You should maintain proper MRP related parameters for both FG and SFG.Check all the MMR parameters :
1.MRP Type -PD for FG/SFG
2.Procurement Type -E for FG/SFG
3.Planning Startegy -10 in FG
4.BOM/Routing Explosion -Keep it Blank
5.Indiviaul/Collective Indicator -not applicable as it is MTS so keep it blank
6.Validity of BOM /Routing should be corrcet before MRP run in MD02-NETCH , 2,1,3,3,2
7.What is the Lot Sizing Set up-EX in OMI4-Scheduling Tab -Requirement date =Delievery Date and BOM Validity Date .
Ref .Re: MRP not plalned for dependent components
8.Check in MRP4 -MRP Dept Requirement Parametre should be balnk for plalling the SFG in MMR of FG -MM02
I hope this issue may be with BOM explosion as per the validity and lot size -schedueling set up .
Hope this will be useful

BOM explosion in chracteristic Plng

Hi
I am trying to map a scenario by characteristic plng. scenario is like, i have steel industry product which is differentiated on basis of grade, dia, shape (major characteristics). and my major objective with plng of finished good is to aggregate molten metal requirement (SFG) on grade wise.
so what I planned is i made configurable material grade wise using material type KMAT, plng stratagy 56.
I have defined character (dia&shape, grade) and assigned to a class type 200(as per literature on sap help). and in class is defined for bom explosion.and in class object are assigned as per characteristic.
i have defined BOM for configure material ,,,,bom item is class(as defined above one) with all required setting.
I have created planning table & profile in DM.
when i m creating PIR ...characteristic wise it is taking but on taking MRP run it is not exploding bom....i.,e it is not picking right material as per class characteristic match.
help me on this
thanks in advance
Rajesh

Hi prakash
yaa...it is variant based planning. but it is based on characteristics and for that I am using class type 200 & strategy 56. as per your reply if I go for strategy 54 than i have to use class type 300 and I have to make configure profile that is not my case.
In my scenario first i have to create PIR for configure material for that pre-requisite is planning profile, planning table & chracteristics combination. I have maintained all these, these thing are all reflected when i am creating PIR (MD61) but when I am taking MRP run Planned order for configure material is generated but dependent requirement is not generated for down level material. I am using class item as BOM component, I don't know why it is not picking right component as per characteristics.
thanks
Rajesh

BOM explosion from Production Order

Hi All,
I understand from SAP Help files that we can explode BOM from Production Order using Read PP Master Data. But it also says, that we cannot do this if items have already been issued out. So would like to know is there anyway out to ensure that the production order is reading the latest version of BOM.
The reason i want to know is because, at present the BOM keeps getting updated & so the work order has to reflect the new items. The BOM contains about 300 or more items, so manual changes is very tedious & error prone at the moment. Furthermore some components are outsourced. So i want to receive them back & post new materials for them. Hope my problem is clear & await inputs
Vivek

Hi All,
Thanks for the inputs. I think for the situation am facing, the Order change management method, should be of help, as the BOM changes does not take place on scheduled dates, for me to fix the BOM explosion dates & assign them. As of now the BOM gets changed, depending the customer requirements, which is unpredictable.
Clarification required:
1. The profile which is created using OPL7 & assigned in OPL9 is unique, i.e. for any change numbers of BOM will always follow the profile entered in 'Overall Profile' in Work Scheduling view & i do not need to create new profiles for each new change number of BOM
2. Once i run the COCM with the new change number, in the production order - components view will i be able to see any error message for those items which no longer feature in the new version of BOM? & will the materials added in the new BOM automatically feature in that list or do i have to manually add these to the order & if so, how will i know which materials need to be added?
Hope the clarifications sought are clear, await inputs

VC - new characteristic does not show in PS BOM explosion / CU50

Hello World,
we added a new Characteristic to a class that is basis for a Material BOM explosion. In transaction CU50, the new characteristic can be configured by selecting its single values and the result shows up correctly in the BOM explosion.
Unfortunately, it is does not show up in the BOM explosion result of the SAP PS module @ Network Activity where the explosion is done concerning to our biz process. All other characteristics explode properly in the PS BOM explosion. I have no clue about the difference of the newly added characteristic is that makes it behave differently (only) in the PS system, not showing up in the result.
In CU50 @ Menu Extras @ Result I found a trace of the difference, but cannot interpret it due to a lack of documentation of the resulting screen that is entitled "Configuration : Result". Here, in table "Detail List", only the faulty new characteristics show additional extra Dependency entries with a light green background that cannot be found with all other characteristics in the same table. These extra entries can be drilled down by double-click and produce a pop-up window that shows some status information and the dependencies source code.
Question: what do the extra entries of dependencies say, why are they shown and why not at other characteristics?
By understanding this difference I hope to find the reason why these characteristics are not exploded in the PS module (which is my primary question).
Thank you for a helpful answer!
Marcus

Hi Jong - Moon cho,
Please check following setting,
1.Consider setting the Individual/Collective indicator to 2. (MRP 4 view)
2.In order to get dependent requirements from the planning of configurable materials, components should not be configured with strategy group 70 or 59.
Also refer the bellow link

Without MRP, with BOM explosion

Hi,
I'm new to SAP and learning SAP SCM. I would like someone to brief me on what the following lines imply, especially 'without MRP, with BOM explosion'.
"dependent requirements must be determined for materials that are planned in SAP ECC. So, you assign the MRP type X0 with MRP procedure X (without MRP, with BOM explosion) to the materials planned in SAP SCM."
Thanks,
Krish

Hi,
Without MRP , with BOM explosion - means the dependent requiremens are created for this materials from APO.
The MRP will not run in APO. Only the dependent requirements will be created from APO. The MRP for this materials will be executed the ECC or R/3 system to create planned order anb purchase requisitions.
Thanks and regards

Discontinued parts in BoM explosion reports

I am having difficulty with the BoM explosion reports (CS11-13, and CSP1-3), in that they seem to take no notice of discontinuation. In particular we have some assemblies which are discontinued, and replaced by alternative parts with a different sub-assembly BoM. It does not seem possible to explode through the new BoM - the reports appear to continue to use the obsolete assembly.
Am I doing something wrong? It would seem clear that the reports should explode the BoM through the new assemblies, particularly if there is no stock of the obsolete part.
Is there an alternative way to get a BoM explosion report which does take note of the discontinuation data?

Hi,
In my opinion discontinuation is considered only during MRP run (planning) and has nothing to do with BOM reports (CS03, CS11, CS12, CSMB, etc).
SAP online help:
If this indicator is set, the material is defined as 'to be discontinued'. The material is then discontinued in MRP. MRP transfers dependent requirements that are no longer covered by stock of this material to the follow-up material.
So, I think you won't see the follow-up material in BOM reports. Even if you maintain the discountinuation in BOM I think you cannot see the actual sitruation in BOM reports (you will see both follow-up and discontinued material).
I hope I'm mistaken and this is a solved issue in SAP.

Csaba

No Bom Explosion for Fert material

I try to create a BOM where a A1 material(FERT) is link to 3 raw material, A, B and C. Enter the qty in MD61 independent requirement, after that i tried to run MRP and found out that there is no requirement/PR created for the 3 raw materials, only the A1 has the indep requirement. seems there is not BOM explosion.
After that i try to create B1 material(SEMI) is link to 3 raw materials as well. But the 3 raws material able to show the requirement/PR after the MPR run.
Am i miss out any step in the config for the material type? or may be other steps?

Dear ,
MRP will explode BOM for FERT or HALB which has valid BOM , based on the following set up :
1.In MRP4 view of FERT/HALB , keep BOM Selection method -Blank or 1 .If you have Production Version with valid Lot size , Valididt dates (To/From ) , then keep the BOM selection method as 2/3.
In case of Blank , MRP will selt the BOM as per the Qty or BOM lot size ( Valid Lot Size-TO/From -CS02-BOM Header )
In case of 2/3 -System will Check the Production Version Validdity or Lot size , select the PV and explode .
2.In OPPQ-MRP Plant parametrs -Keep BOM Explosion indicator as Blank -BOM explosion method /order start date .
3.Keep MRP Dep.Req filed in MRP4 vewi of FERT /HALB as Blank ( meand you want to plan the dependent ofr FERT/HALB-BOM Compoenet -a,b,c etc )
4.All the material (FERT/RAW/HALB) should have porper MRP1-MRP4 view parameters like MRP Type -PD , Procurement Type E-In house /F-External procured item .
5.All the material should be Block for Procurement in Basic Data1 -X plant status as 01
6.All of them should have Planning File Entry in MDRE/MD20/MDAB
7.Run MRP in MD02-2,1,3,3,2,NETCH
Hope this is clear .Check Point 1 to Point 4 frist and try

BOM Explosion setting in SPRO

Dear Gurus/Friends
This is related to SPRO->Plant Parameters->Bom Explosion
Here there are 5 selections
     BOM explosion number/order start date
1     Order start date
2     Order finish date
3     BOM explosion number/order start date
4     BOM explosion number/order finish date
Here there is no difference between empty and 3
Could any one explain the total concept
K.Prabakaran

Hi praba
BOM in SAP is dynamic one. The validity of BOM is from any date upto the system valid date.
If you have run MRP at FERT level for ex today 14/05/08. The dependent requirements are exploded based on the valid BOM of this date.
If you have multi level BOM and you proceed from bottom level to top level by converting plan order to prod order step by step. You assume it takes 10 days to come up to top level.
In the middle, if you have changed BOM at particular low level code. While converting plan order to prod order system will take the valid BOM on that date. It will not look on the Explosion date of 14/05/08.
If you use BOM explosion number with fixed key date. BOM will get exploded always of the fixed key date of 14/05/08. Till the top FERT level is completed and made GR.
This BOM explosion number will be given in PIR agsint the requiredment.
Hope this is clear.

J . Saravan

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..
Regards,
Prasobh
