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.

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 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

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.

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..

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 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.

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).

Copy Order Bom in Two-Step Variant Configuration

Dear Community,
In Multilevel VC Order Bom Scenario. Configuration is made for the first level by sales department, then further levels are configurated by Technical Department.
If the sales document is a quotation and then we want to create de sales order with reference to the quotation, only the configuration for the first level is getting copied. All the characteristics of the lower level configurable materials appear in blank, as well as selected class items in quotation as well as manually added components.
Is there a way to copy the whole order bom of the original document or the characteristics value for every level?
Thank you
Sebastián Ligueros

Hi Rahul,
Basically , an order bom doesnot explode therefore you cannot configure any of the components.Please review note 303446
By changing the default value of the variable GV_FORCE_BOM_EXPLOSION_ASL in Include LCUKOFBE, you can force the explosion of the order BOM in the sales order.As a result, subordinate items of the order BOM are configured provided that these items were not fixed.I
Therefore please set this variable GV_FORCE_BOM_EXPLOSION_ASL to X and retest,
Thanks
Amber

I think it is useful for you.

Bom explosion in MRP

Hi
I have following scenario -
I have Regular Sales order bom For one material X in Plant A and as long as engineering is not completed, this Sales order bom is having status inactive. Once engineering is completed then it will become active.
For Same material X in Plant A material BOM also exist ( It is used for stock transport order) and I dont want MRP should select material BOM if it doesnot find Active Sales order BOM.
How to achieve this.

Hi
Try these steps
1) Create BOM Selection ID in SPRO
Sel ID(say for ex 09) Sel pr (1) Usage (5)
2) Assign the ID in OPPQ under BOM/Routing selection Tab
During MRP system will chk for the Usage Priority and if it found any active sales BOM then only it explodes or other wise it don't consider any other BOM

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.
Regards
Srini.

Routing details with bom explosion

hi friends
i have developend the report for pp,in routing details
how to get the details of bom explosion with workcenter and routing operations

Process order with variant configuration material

Hi,
I create a process order for a material XX.
This material has a BOM with a material that has variant configuration "class type 300" for price configuration.
When I save the process order I get a message saying "There are still characteristics for components to evaluate". I dont want to evaluate this material in my process order.
What can I do to not have this message?
Regards.

Hi all,
Yes, I work with variant configuration. But sales orders are not involved.
What I do is:
1) I create a purchase order for material X (this material belongs to a BOM), this material has variant configuration. I give a value to the characteristics in the PO.
2) I create a process for a material XXX that has a BOM (material X is in the BOM and cannot be removed).
3) When I save the process order the system asks me to evaluate again the characteristics. This is what I dont want it to do.
Any ideas?
Regards.

Multilevel variant configuration without BOM explosion

Hi!
We have the following problem:
We use BOMs with variant configuration in SD and NO BOM explosion. Means, enter the BOM-head material in the SD line, go to the configuration screen and configure the multilevel BOM. There are classes and attributes on every level in the multilevel BOM structure.
After finishing the variant configuration, we save the SD order. If we enter the new SD order again with VA03 and go to the configuration of the SD line, the system forgot every attribute value on levels other than the BOM-head. We see the structure of the selected BOM materials, but no previously entered configuration value on other levels.
Do we make something wrong, or is this a SAP standard "feature" ?
Thanks,
Richard

Hi,
This is a standard feature.The values which you will select for the configurable material,you will not able to see when you got to VA03.
Reward points if helpful.
