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

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.

BOM Explosion Number in Sales Order

Hi Experts,
For a make-to-order case, I would like to assign a predefined BOM explosion number with fixed key date to a sales order item. Instead of manually assigning the BOM explosion number to the sales order item, is there any way to let the system automatically assign the BOM explosion number?
As I read from SAP Library under the BOM Explosion Number (Fixed Key Date), it states "The system can automatically specify the BOM explosion number when entering planned independent requirements or customer independent requirements or when entering the sales order." So is there any configuration to be done in advance to enable the BOM explosion number to be automatically assigned to sales order item?
Thanks,
SW

I tried also setting up the material and its BOM determination by specifying only 1 BOM out of multiple BOMs. Still,
1. When I add the said material into sales order line and save the sales order, the BOM explosion number value never appear automatically in the sales order line.
2. When I run the planning on the sales order through MD50, the planned results do not have the BOM explosion number attached.
I think your advice is more applicable to selection of a BOM from multiple BOMs instead of determining the fixed key date based on appropriate BOM explosion number, correct me if I am wrong.

Bom explosion in sales order mrp(MD50)

Hi Experts,
In sales order MRP i.e. MD50 Getting the planned orders for header material(Finished goods) generated but for raw materials (BOM items) Purchase requisitions are not getting generated.
Details:
Header material A and raw materials B and C.
In material B in MRP 4 coll/ind indicator is 2 And same indicator for C is blank.
Now when we are running the MRP sales order based it will generate the purchase requisition for C only but not for B.
In OPPQ we have done the setting for sales order BOM explosion.
Can anyone please throw some light what is the setting missing in customization or in front end?
Thanks in advance.
Regards
Vilas

Dear,
If you select individual requirement then system will not consider available stock and generate Proposals for every single requirments. Check in MRP4 view Individual / Collective .
Also you will find PR and Plan order with account assignment of Sales order (in case of MD50).
- If you select collective requirement then system will not generate planing proposals through MD50.In that case you have to go for individual MRP (MD02 / MD03)
Please try and come back.

BOM explosion in Sales order with material variants

Dear all,
we would like to work with Variant Matching in the Sales Order. Additionaly we would like to explode the BOM....according to the SAP help this is not possible....
http://help.sap.com/erp2005_ehp_06/helpdata/en/bd/05a7d69d3211d190380000e8a49aad/frameset.htm
Does anybody of you has any ideas how and where to make this happen?
Thanks for your help and kind regards
Jan

Hi,
I have gonethrough the SAP link referred by you but never come across with any problem in type matching during Sales order even if the BOM explosion is set for Multilevel in Configuration Profile provided the other pre requisite set up was perfect.

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.

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 in BOMBOS transfer

Hello,
can any one tell me how BOM explosion happens in BOMBOS transfer? Thanks!!
Regards,
Saravana

Dear Saravana
I believe if you use "standard" configuration the is no BOM explosion done. This is not needed. The reason is "simple". Any BOM item must be as well a specification. Thsi specification will have it self a composition. The BOMBOS transfer "end" normally on REAL_SUB level. Therefore the "leaflet" REAL_SUB must be maintained by youe (composition) either using PURE_SUB or LIST_SUB. But if needed: there is some user exit available (more than one) which you could try to use so that the "BOS" which is generated on EHS side is the "exploded"
The reason why this is all "customer" specific developmet is "quite" easy. You have a "main" BOM per plant; and you have alternative ones. How should the "explosion" be done? The system can not know thos. Do you always would liek to use the "Standard BOM"? Don'T know. But oplease check paralell thread:BOMBOS transfer SPRO settings and technical details

BOM Explosion in CRM & ECC

Does anyone know of a way to control Sales BOM explosion at the item category level in the middleware? We have boms created in our ECC system for both standard and configurable materials. For our standard materials I need the sales BOMs to explode on the CRM order (for ISA shopping basket purposes) and to prevent a duplicate explosion in the ECC backend I have parameter NOSTRUCTURE set to X in SMOFPARSFA.
CRM does not support using configurable products as the header or component of sales boms so for these materials I do want the bom explosion to happen in ECC as the order flows from CRM to ECC.
I've tried adding order types and item categories to the parameter names for NOSTRUCTURE but it didn't work. OSS confirmed my findings that it would not work.

Hi,
I did work on single level BOM explosion in a couple of projects. As per SAP note 549341 - FAQ: BOMs in the sales order, it is very much possible to explode multi-level BOMs.
Check this note and item category BOM explosion options.

BOM explosion in CRM Service Contract

Hello
We want have a BOM explosion working in CRM for service contracts
Here are the details :
We have replicated the materials from ECC to CRM. We are not maintaining any BOMu2019s in ECC.
The idea is that we maintain the BOM Structure in CRM only, as we donu2019t want to have the Items as a billable item in a position, only for information purposes (or later on for metering)
We have maintained the product category for the header product in CRM so we are able to maintain depended components
(Relationship type SCDEC S Dependent Components (DC) )
Not we are able to assign dependent component to the header material
Item category groups:
We understand that the standard item category groups that should be used are ERLA for the header product and LUMF for the Item product.
In order to support the same functionality for the given item category group , maintained at the product level in ECC we copied the same setting for the item category group from the standard to
our settings.
Standart
Tx type Item Cat Group item category structure scope
TA ERLA TAQ A single level Explosion of Structured Product
TA LUMF TAP A single level Explosion of Structured Product
So we have copied TAQ to ZTAQ and TAP to ZTAP.
ZS01 is a copy of SC (service contract)
Tx type Item Cat Group item category structure scope
ZS01 ZLEI ZTAQ A single level Explosion of Structured Product
ZS01 LEIS ZTAP A single level Explosion of Structured Product
But when we use a header product in the service contract, we cannot see the BOM is exploding.
We have also created some products in CRM with exactly the same Item Category groups as the standard and when we create a standard order (TA) in CRM, the BOM is NOT exploding.
Questions:
Is it possible to have the BOM setup only in CRM, like we try to do it?
Is it possible to use our own item category groups in CRM more is the functionality only working with ERLA and LUMF?
Is it possible to use the BOM Explosion in Service contracts as well ?
What steps are we missing to get the BOM explosion in CRM ?
Thank you for your help

BOM Explosion in Quotations

Hi All
please can you advise ifa BOM explosion in a Sales Quotation is this standard SAP?
Kind Regards
KC

Please check the configuration in Menupath:
SPRO> Production planning > Material Requirements Planning > Carry Out Overall Maintenance of Plant Parameters
or T.code: OPPQ
If you have not maintained the plant parameters, please copy the same from any SAP std plant.
If you have already maintained, lcik on MAINTAIN button.
Then go to BOM Explosion button and Check the Sord/WBS option
Hope it works,

BOM EXPLOSION IN SUBCONTRACTING SCENERIO

Hi,
To all Experts,
This is regarding the bom explosion in subcontracting P.O(scenerio).Scenerio prob. is explained as follows -
1) I have an assembly which includes the semifinish & raw materials.
2) By cs11 it explpodes whole BOm
3) When i made P.O. for job work order(subcon.), in mateial data view it displys only the semifinish components(i.e. component or explode bom) ,but not the raw,which we want to send to vendor.
so due to above,how we can determine, what the material we are sending to vendor?
In short i want to explode the bom in po,in which it displys the semifinish as well as its raw.
So please suggest a propper solution for above query.
Hoping suggestion quickly
Thanks in advance
Manish

Hello Manish,
Could you please tell me how you have resolved this problem. I have the similar requirement.
"want to explode the bom in subcontracting po,in which it displys the semifinish as well as its raw."
we are exploring the PHANTOM ASSEMBLY but still no luck.
When i set at BOM item level - Phantom Assembly off indictor and Spec. Procurement 50
system is still requesting for transfer of Phantom Assembly instead of components to the vendor.
Thanks in advance

BOM Explosion in Shopping Basket for CRM B2C 6.0

Hi Gurus,
Can we have a BOM explosion in shopping basket . As per few links I explored BOM Concept is possible only in ECC and we can implement it is CRM based by some additional configurations . (BOM in CRM) .
We have configured component for products and XCM setting for BOM is also in place . But BOM explosion is happening only at Order confirmation level .
Can anybody give some insights to get BOM explosion in Shopping Basket of CRM B2C 6.0 .
Thanks and Regards,
Tony Isaac

Hi Rahul,
Thanks for the reply.
I could find the UI component setting : ui.fields.order.bomExplosion = Visible and I have already done this . Due to this I am able to see BOM explosion on Checkout Page / Order Confirmation Page .
But still I am not able to find ui.fields.order.subitemDetailview = Visible.
Is that available only in R/3 version ?
My problem is BOM explosion is not visible in Shopping basket .

Tony Isaac.

Material BOM explosion in Service Order components

Hi experts,
I created a Material BOM with transaction code CS01.
Then I try to add this BOM in the component of a service order.
What I expected is the BOM to be exploded in the service order. But this behaviour doesn't occur.
Do you know what I can do to trigger a Material BOM explosion at service order level.
By the way, the BOM is not exploded after the service order (in the reservation or in MIGO).
Thank you for your help.

Hi Özgen,
Thank you for help.
Special Procurement 50 didn't exist in my system.
I created it in SPRO for the plant with the Procurement Type F (External Procurement) and the flag Phantom Item checked..
Then I created
- Material A (MM01)
- Material BOM A (CS01) with:
-- item 1 Material B (which has Spec Proc Type 50 in MM02-MRP2)
-- item 2 Material C (which has Spec Proc Type 50 in MM02-MRP2)
After that I created a Service Order (IW31)
I put Material A in the Component tab with quantity 1.
The BOM remains unexploded.
Did I miss something?

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

BOM explosion number.

Hello SAP Gurus,
What is the use of BOM explosion number? after creation how & where to assigne it?
with regards,
dev123.

Hi,
If you want to ensure that for a certain production unit, the BOM structure is always exploded with the same date, you can assign a BOM explosion number to the planned order (or for make-to-order production it can be directly assigned to the sales order).
If you do not use the assignment of a BOM explosion number, the planned start date of the planned order is always used as the explosion date for the BOM. The system explodes the particular BOM that is valid on this date.
For multi-level BOM structures, larger time intervals may exist between the explosion dates of the individual assemblies. If BOMs (or alternative BOMs) have been changed in the meantime (for example, exchanging individual components due to new technical drawings, changed production techniques, due to parts to be discontinued etc.) a situation may exist whereby an assembly that is used repeatedly is produced with different BOM structures.
Create BOM Explosion Number:-
1. Starting from the MRP menu, choose Master data --> BOM explosion number -->Edit (MDSP)
The system displays the initial screen for maintaining the BOM explosion number.
2. Choose .
The screen for maintaining the BOM explosion numbers now appears.
3. Choose New entries.
A screen now appears where you can enter new BOM explosion numbers.
4. Enter data as required.
BOM explosion number
The BOM explosion number is the object for which the following data is maintained. It can be entered alphanumerically.
Fixed key date
The fixed key date determines which bill of material is exploded.
Plant
You can also specify a BOM explosion number for a specific plant. Enter the appropriate plant in this case.
Material
You can specify a BOM explosion number for a specific material. Enter the appropriate material in this case.
Status
You can set the BOM explosion number to active or inactive using the status field. Only active BOM explosion numbers are used in the planning run.
Save your entries.
