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.

Alternae BOM during MRP RUN

Dear PP Gurus,
I have a finished product for which there are 2 bom, When I run MRP for this finished product , which BOM system will consider? Is there anyway by which i can deicde which BOM it should consider?
Please help.
Thanks

Dear,
If a product contains more than one alternative BOM,try to mention this by creating different prod.versions.
You can assigne 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),
Also selection method is maintained in Material master MRP4 view.whether the BOM needs to be selected through BOM Qty. Explosion date or Production version....
Or use BAdI MD_MODIFY_PRODVERS.

Materials planning for Recursive BOM during MRP run

SAP Guru's,
We developed an recursive BOM as per production requirments , but we didn't know the impact of this recursive BOM during MRP run.
Pls help us how to recursive bom behaves during MRP.
Thanks & Regards

Hi,
This message was sent to us by SAP when we were having the same kind of requirement. Hope it will help you too.
Usage Probability
Material requirements planning (MRP) plans the alternative items according to usage probability.
If you use the usage probability to determine the withdrawal posting (strategy 1), the quantities are proposed according to the usage probability. You can change the proposed quantities.
An alternative item is only planned if the usage probability is at least 1%.
If the usage probability is 0%, a dependent requirement with quantity
0 is generated for the material.
The component with the quantity 0 is displayed in the planned order.
If required you can increase the quantity there.
It is possible to plan too much for alternative items, because you can enter usage probabilities that add up to more than 100%.
Hope it will help you.

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 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.

Schedule lines are not getting generated during MRP Run

Schedule lines are not getting generated during MRP Run. I have maiantained source list for the material with proper validity date and also maintained scheduling agreement . MRP relevvant Indicator , I have marked - 2 which means -Record relevant to MRP. Sched. lines generated automatically.
Still I am not able to get schedule lines and instead of that *Purchase Requisitions* are getting generated.
Can any one help me and suggest me what to be done in this case .
Thanks & Regards ,
Nirmalya

Dear,
Welcome to SDN,
In transaction OMDT you have to enable the indicator create schedule lines
In MD02 MRP control Prameter here select the Delivery schedules -3- Schedule line. Processing Key as NETCH and Planning Mode - 3 delted and recreated.
Maintain source list ME01, in that put MRP indicator as '2' i.e. schedule lines via MRP.Put your agreement no in that.
If u run MRP properly u will get schedule lines automatically in ME38.
Make the schedule agreement, make it source relevent in the source list make is FIX and MRP indicator as 3.

Alternative items during MRP run

Hi,
I have seen discussion on alternative items in BOM. Thanks for all for sharing your knowledge. I knew alternative items will be choosen while creating / release of production order (material availability check)
Requirement:
For material A, I am using component B as priority 1 and component C as priority 2.
During MRP run, system needs to CHECK component B first. If stock is not available for component B then system need to consider component C automatically. It should not create any planned order for component B.
Is it possible, system will check automatically alternate items during MRP run? if so kindly let me know the logic.
If not, is there is any user exit. Customer is asking this facility. Its his basic requirement.
Kindly give your suggestions....
Regards / US

Hi.
I might have typed it wrong, I think the right one is called DIMP.
As far as I know you don't have to purchase it. In the past those extensions were known as Industry Solutions, in this case Automotive and A&D.
Before you go to this complexity for interchangeable materials functionality in MRP, I recommend that you have a design review with your customer, to strengthen the point that if two materials are the same for all usage purposes, but only differ, let's say, in the source (different manufacturer). for that in SAP we would define ONLY ONE material number, with additional manufacturer part number info, and in some cases with a classified batch.

Storage location consideration during MRP Run

Hi All,
Within a company code, i am having 2 plants namely PS12 & PS13. In plant PS12, i am three storage locations namely 1201, 1202,1203. Similarly in plant PS13, i am having stores 1301,1302,1303.
During MRP run, i do not want to consider the stock in all the storage locations of PS12. The storage location 1203 to be exclued during MRP run. How to set this?
Your input will be appreciated very much,
Thanks
Kumar

Hi Kumar,
Goto SPRO>Production>Planning>Define Storage Location MRP per plant, add the storage location to be ignored during MRP and select indicator '1' against it. Thereafter, all the materials created with this storage location will be defaulted with value '1' in the field 'SLoc MRP indicator'. However this can be modified later if required.
For existing materials, select indicator '1' in the field 'SLoc MRP indicator' avaialble in MRP view under the column 'Storage location MRP'. Go for a mass update for a huge list of materials.
Check this and revert for any clarifications.

Rounding of Decimal for dependent requirement During MRP Run

Hello Experts,
I have the following scenario:
We are currently enabling Characteristic Based Planning in our system.
Our one component is selected when two characteristic values are met through object dependencies.
Ex: Component A = Char A= '002' and Char B ='002'
Now we have given the following Usage Probability for the two characteristic:
Char A = 20%
Char B = 15%
And the total PIR quantity is 25 Pcs for Configurable Header.
With the above usage probability and PIR Qty, We have a dependent requirement of 0.75 Ea
((20% X 15%) of 25 Pcs) = 3% of 25 Pcs = 0.75 Ea of the component
Now during MRP Run I want to round the dependent Requiremnet to 1 Ea instead of 0.75 Ea.
Any suggestion towards the solution will be appreciated.
Regards,
Vinod

Hi Vivek,
As mentioned we are using Characteristic Based Planning.
The component is selected based on a Selection comdition which is as follows:
Component 721290201000 = $PARENT.BCS_RL_LINE_LOADER = '002' and $PARENT.BCS_RL_WAFER_VENDOR ='002'
When the above two conditions are met the component is selected.
In Characteristic Based Planning we give percentages (Usage Probabality) to the characteristic values like:
$PARENT.BCS_RL_LINE_LOADER/'002' =20%
$PARENT.BCS_RL_WAFER_VENDOR/'002'= 30%
For the Parent which is a KMAT Material we maintain the PIR say 40 Qty.
Now the component qty is calculated as follows:
721290201000 =(20% X 30%) of 40 Qty of parent
721290201000 =(6%) of 40 Qty of parent
721290201000 = 2.4 Qty of component is the dependent req.
Now my requirent is to round the dependent requirenment to 3 during MRP Run. Please note that the purchase requisition got from the above dependent requirement is rounded to 3 qty.
Now I want to round the dependent requirement.

Vinod

Contract number is not being picked during MRP run

Hi,
I have a contract with vendor as V1.
This contract is MRP revelant with source list maintained with MRP revelant.
Source list maintained with vendor V1, contract and with fixed indicator and with MRP relevant indicator set.
Step 1
Now I am executing MRP, system is creating PR with contract vendor V1 as source of supply is V1 in source list.
This step is OK.
Step 2
After this I am maintaining sub contracting vendor V2 in contract.
Again I am executing MRP run, system is creating PR, but the PR is not picking the contract details.
I am expecting this PR, which supposed to be created in this Step 2 should have vendor V2 as source of supply.
Am I correct?
Note: Source list is still having vendor as V1, same contract number, with fixed indicator and MRP relevent option set.
Any input if process is OK or if some thing wrong is apprecited,
Thanks
Dipak

Hi,
Ok.
I am following this way -
In ME32K, there is a delivery address button available is transaction tool bar, there I am maintaining the subtracting vendor number and enabling the SC vendor check option so that this vendor flows to PR which gets created during MRP run and comes to PR delivery address tab i.e., in vendor field as subcontracting vendor with SC vendor check option selected.
Am I correct ?
Thanks

How to change PR Qty before rounding value is applied during MRP run?

Hi, SAP gurus~
I have an inquiry about how to change the PR qty of specific raw material before rounding value was applied during MPR run.
Here is a simple example for what I needed.
-SAP Original Logic
1. Original requirement Qty: 190
2. Rounding value at Material Master (MRP1 View): 200
     System will suggest PR Qty 200 at MD04.
-My Customer Requested Logic
1. Original requirement Qty: 190
2. Additional buffer Qty for C/S purpose: 10 % of Original requirement.
3. Rounding value at Material Master (MRP1 View): 2000020
     Requirement Qty would be 209 (190 + (190 x 10%) ) before rounding value is applied and system should suggest PR Qty 400 at MD04.
-     I input assembly/component scrap rates (10 %) at Material master for above purpose, but it doesn`t not work for raw material.
-     I tested the BADI (MD_PURREQ_CHANGE/ method: CHANGE_BEFORE_SAVE_MRP), but I can only change the PR Qty, which rounding value already applied.
How can I change the PR qty during MRP run before rounding value is applied? Is there any other method or User-exit possible to solve above problem?
Thanks in advance.

Dear ,
How can I change the PR qty during MRP run before rounding value is applied? :
Simple way is goto MD04 with your material and plant code -Select the PR-Hit the pencil (change mode ) -Choose qty field and change , SAVE at individual level .Or Use : MEMASSRQ - Mass Maintenance
If you want to use User Exit , then you try a work around :
M06B0001 Role determination for purchase requisition release
M06B0002 Changes to comm. structure for purchase requisition release
Try and let us know if u have any issue .

Consideration of stock of discontinued FG or trading material during MRP Run

There is an functionality of follow up material for component. I would like to know if there is any similar option available for finished goods or trading materials.
I am doing procurement planning for externally procured Trading materials. Now my previous material A is being replaced by material B. Therefore all the planned independent requirement is available in system only for B. But still there is some stock available for material A. How can it be considered during MRP run for material B.
Example,
Material A:
On Hand Stock = 100
Planned Independent Req. = 0
Material B:
On Hand Stock = 300
Planned Independent Req. = 1000
In this case if we run MRP for material B, how we ask system to plan Purchase Requisitions for 600 instead of 700 for material B, considering stock of material A.

Hello
Please refer to the following SAP note:
43636 - Discontinued parts
This note provides a detailed explanation of the system standard design of the usage of discontinued parts with material requiremenst planning and the most common questions about this issue.
The following information is provided on this note regarding the PIRs:
2. Planned independent requirements and forecast requirements are not redirected.
Explanation: Planned independent requirements after the effective-out date are not redirected but are provided with an exception message in the MRP list stating that they cannot be included in the availability check. Planned independent requirements and forecast requirements are therefore displayed in the MRP list and in the stock/requirements list. However, they do not influence planning

Intercompant STO working during MRP run.

Dear Experts,
How intercompany stock transfer works during MRP run?
I mean if one company is purchaser and other is vendor and purchaser company's planned delivery time is 10 days and replenishment time in other company is 3 day then will system consider these two times in creating purchase requisition in first plant ( in MD04)?
Regards
Deepak Sharma
9818263889

Hi,
Say your purchaser is plant A, vendor is plant B. STO can make by spl.procurement key 40 in MRP2 view in plant A.
If you create requirement in plant A, system will create planed order for that material.In plant A, system will consider only planned delivery time of 10 days.
In plant B, system will create dep requirement. suppose if stock is not available that time system will consider to replinishment the material as 3 days.
This 3 days will not consider in Plant A.

Cheracteristic consideration during MRP run

Dear frnds,
during implementation for one steel industry i have stuck up in problem which is
they have crm plant in which finished products are endless depending upon thickness like .023,.325
if we make material master for every thickness then it will infinite number of material master.
so we thinking for single material master group of thickness i.e for single mmr for range of thickness and during sales order creation person will mention actual thickness in text of sales order or we can make it configurable and characteristic for actual thickness so during he will mention actual thickness in characteristic value.
but problem is that during mrp run, characteristic value is not taking into consideration,
so i want some customization so that characteristic value is considered during mrp run
please help me out its very urgent
thanks

Hello,
are you talking about a pure ERP implementation? A good description on modelling this with APO can be found in the Best Practice for Primary Steel (see link on BPX Mining and Metal).
Usually we work with configurable material variants, as a starting point.

Stefan
