Extend Material to Different MRP Areas

Hi Friends!
I want to extend a material to different MRP areas. Is this possible using BAPI_MATERIAL_SAVEDATA? I couldn't find the MRP area field(should be an input table holding multiple records) in the BAPI to input for extending the material.
Or is there any BAPI/FM available for this?

MRP fields are in the PLANTDATA structure.
So I guess it should be here.
What is the SAP name of the field you are looking for ?

MRP areas--Component To be issues for different MRP areas

Dear All
I have this scenario for MRP areas--- MRP area 2000 and 3000..these areas are basically 2 separate physical production facitilties...One is main production plant and other is lab for making samples.... But they store the raw material stock seprately..stock for raw material for main production is in main warehouse 2000 and stock for samples lab in in their mini warehosuese 3000.
Busniess wants to consume stock from main production warehosue when doing main production and to consume stock from samples warehosue when doing samples production. BUT header item is same and raw materials are also same. Means the same BOM.
Example-- FG1 and it has RM1 and RM2 in BOM
Kindly help to do settings\configuration somehow that when we do production in 2000, compoenent are comsumed from 2000 and when we do production in 3000, components from 3000.
I extended FG on both MRP areas. even for RM1 anf RM2, i extended it on both MRP areas. So in MRP2 view prodcution stprage location is 2000 and with MRP area MRP 2 view production storage location is 3000.
It did not work.
Kindlt sugget

Hi,
What you need is a way to determine the proper issue storage location for the two cases.
Since, as you say, the BOM is the same, you need to use production versions. In the definition of the production version you can control the issue storage location for the components of the order.
All you need then is to choose the right production version for each case when you create the order.

FG in MRP AREA and ROH comoonents are in different MRP AREA

Dear consultantas,
please i need to check this scenario with you if applicable or not:
i have ine plant 0001 and i created 2 MRP Areas 0001 (plant MRP Area) and 0002 (storage location MRP Area)
my finished product is planned in MRP Area 0001 and its components (in BOM) are planned in 0001 MRP Area.
do you think this scenario is applicable.

Hi
You can map this business process very well in the standard SAP .Only thing is you have to make sure that both the MRP area are activated for MRP and Planning file entry to be done foe those FG and componenet which are in different MRP area .You can include them in SCOPE of Planning in the configuration and run MRP in MD01.Or u can run MRP in two different MRP area as per your requirement .
Hope this will help you .

Extending material to other sales area

Hi,
Can a material can be extended to a new sales area, which is having enitrely different Sales Org, Dist Ch & Div? If yes, Pls explain.
Regards,

Hi,
Just assign the sales org + Dist. Channel combination to the plant where this material is existing. But remember a material cannot belong to two divisions at the same time. You can fulfilll the requirement by maintaining the sal org, dist chan link to plant.
Pl reward if it helps.

Pass on Material requirements to MRP areas within Plant

- We are on ECC 6.0 & have a scenario wherein material requirements from depots are passed on to respective plants according to the settings defined in the Special Procurement key in the Material Master (MRP View)
- The requirement from depots are passed on to the manufacturing plant & further down to the Plant in which MRP areas are defined, in the form of Planned Orders, if the stock is not sufficient at depot.
- For Subcontracting, we have various MRP areas within a single separate plant. The requirement is that PR that is generated for STO should be able to pass the requirement to an MRP area (after stock checking at MRP area level), (system to decide the MRP area to be selected for passing on the requirements).
- Currently the system is passing the requirements & checking the stock at plant level only.
- Stock determination rules donu2019t seem to work here.
- The opening up of the u2018Issue storage locationu2019 in STOu2019s by config: (u201CPurchase order-> - Set up Stock Transport order - > Set up Stock Transfer between storage locationsu201D) is yet to be tested.
- But in that case, only a single MRP area is defined for the material & therefore the requirements may flow directly to that particular MRP area. In case of Multiple MRP areas being defined for a single material, how can we ensure that the system determines a stock checking at one particular MRP area & pass on the requirements to it.
Seeking guidance as to how this issue can be resolved.
Precisely,
REQ.FRM>FLOW TO>AS (MRP element)
Depot>Plant 1>Planned order (PlOrd)
Plant 1>Plant 2>Material reservation (MtlRes)
Plant 2>MRP area of Plant 2>Transfer reservation (TrnRes)

dear colleague,
Please check the following info that can be useful:
1) Note 358936 is relevant for MRP areas of type storage location and
   not for Subcontractor MRP areas (which you would be knowing).
2) Secondly this note was created as an advance development and not
   for any particular customer problem. It was also feasible to
   develop this functionality with a small change.
3) The feature of procurement with Schedule lines for components
   in subcontractor MRP areas is not available in the standard SAP
   suite and there are no plans to develop this in the near future.
   This feature would be an advance development.
best regards

Extend Material to Different Plant

Hi,
Is there any way through which i can extend my materials to other plants. Right now i have materials in plant A, i want the same materials to be available in plant B. One way is through abap upload programs, is there any other way???

Dear Mithun,
If it's for a single material then you can create the same material (same material type also) in MM01 using
Copy from material option and then you can mention in which plant it's to be created and from which plant
it should be copied.

One material extention to different sales areas and Act .***.grps?

Hi,
I have one material for which i need to extend the material to different distribution channels,divisions and account assignment groups in this case can i extend one material to different sales areas as mentioned above or i need to create one more material with same material master data except the sales view data?
thanks.

I have extended the same material to 2 different distribution channels and divisions but when iam checking in display view of MM for different distribution channels divions should be different as i have given divisions also different but in my case the last saved division only appearing for both different distribution channels.
Second thing in MVKE table iam not able to find the division field(SPART)?
Is iam missing any setting?
Thanks!

Query related to RM maintained for two MRP areas.

Hi PP Gurus,
The scenario is we modeled two Storage location MRP Areas say 1001 and 2001. There are two FG getting manufactured at them, say FG-1 at 1001 and FG-2 at 2001. Say there are three RMs viz. RM-1, RM-2, and RM-3. RM-1 and RM-2 included in FG-1 BOM and RM-3 and RM-2 in FG-2 BOM. Means RM-2 is common in both MRP areas.
Now I've extended FG-1 and FG-2 for respected MRP areas. RM-1 extended to MRP area 1001, and in MRP views of material master, Production storage location and Storage location for EP is maintained as 1001. Same is maintained for RM-3 except MRP area as 1001, it's 2001.
The concern is about RM-2, though I extended RM-2 for both MRP areas i.e. 1001 and 2001 but I can maintain Production storage location and Storage location for EP either as 1001 or 2001. So whenever I'm taking MRP run, for RM-2 it's either proposing 1001 or 2001 as Storage location for withdrawl or EP.
My requirement is when I run MRP for FG-1 system should show me Sloc for RM-2 as 1001 and in case of FG-2 as 2001.
As a try I tried to remove Production and Issue Sloc from MRP views and maintained Issue Sloc/Receive Sloc in PV of FG-1 and FG-2 but still unable to get the requirement fulfil.
Please make prompt comments
Thanks & Regards,
Abu Arbab

Dear ALL
my requirement is exactly same as above that i need my component to be issued from different slocs depending on diffreent MRP areas in which they are being planned.
But in my case FG is same and is being planned in 2 different MRP areas. So my BOM is same in both cases.
For eaxmple--2000 is MRP area 1 and 3000 is MRP area 2
Requirement is components should be issued from 2000 when panned in 2000 and from 3000 when planned in FG is planned in 3000.
Kindly let me know what settings are required at components level to do this
thanks

Multiple MRP areas to be handled with MD04

Hello to all,
my scope is to advice the user in MD04 when there are other MRP-Areas for the same material in the same plant and maybe offer a function to jump there directly. I am looking for suggestions how to solve this, maybe one of you did it already...
Thanks to all
Joerg

Hi ,
Yes u can use multiple MRP area for the single plant & SAp has given Provision to go to differant MRP area from MD04 , only u have to cchange the MRP area option in the MD04 screen , you will directly jump to given MRP area of that material & u will get the stock & MRp element details of the selected ,material.

How to extend material/customer

Hello Experts
If I want to extend one material for different plant/sales org/storage location then how can i do this . Same for the customer , if i want to extend that customer for other sales areas then how can i do that ?
Regards-
Abhi

Hi,
You can extend material to different plant and sales organisation by using the T.Code "MM01".
Enter the material number you want to extend and enter the same under copy from.Press Enter.
Select the required views and enter new the plant and Sales organisation you want to extend.
In a similar way,you can extend customer data as well.

Sap pp -MRP-area

Hello SAP-Guruu2019s
Pls tell me the Procedure/steps/Details to maintain MRP-area for a Vendor & also for a Sub-Contractor.
Any comments welcome & Thanks in advanc

Hi,
Pls. find the following details regarding MRP Area :
MRP Area
Definition
The MRP area represents an organizational unit for which material requirements planning is carried out independently.
Basically, there are three types of MRP area:
Plant MRP Area
The plant MRP area initially contains the plant together with all its storage locations and stock with subcontractors.
When you have defined MRP areas for storage locations and for subcontractors and you have assigned the materials, the plant MRP area is reduced by exactly this number of subcontractors and storage locations. This is because they are now to be planned separately.
MRP Areas for Storage Locations
You can define an MRP area that consists of a particular storage location, by creating an MRP area and assigning the storage location to it. Material requirements for this storage location are then planned separately from the rest of the plant.
You can also group several storage locations into one MRP area, by creating an MRP area and assigning the storage locations to it. These storage locations are then planned together.
A storage location of a plant may be assigned to only one MRP area.
MRP Areas for Subcontractors
You can also define an MRP area for each subcontractor.
A subcontractor may be assigned to only one MRP area. An MRP area of the subcontractor type may also only contain one subcontractor.
Use
You can carry out MRP specifically for the determined MRP areas. This enables you to carry out differentiated material requirements planning. The requester can be, for example, the production on a particular assembly line or a subcontract order.
The MRP area allows you to have specific control over the staging and procurement of important parts produced in-house and purchased parts for each shop floor area. You can, however, also plan the provision of components for the individual subcontractors.
MRP areas of the storage location or subcontractor type are only suitable for:
components that are planned and produced for stock
finished products that are planned and produced for stock. By assigning a storage location in a sales order or by entering an MRP area when creating the planned independent requirements, you can define whether a material is planned in the plant MRP area or in the MRP area of the storage location.
Finished products and important assemblies intended for make-to-order or engineer-to-order production are always planned in the plant MRP area.
The planning run takes into account the planning with MRP areas as follows:
If you do not enter a separate scope of planning, the system plans the whole plant, that is, all MRP areas in the plant, during the total planning run. If you want to carry out a total planning run for a particular MRP area only, you must specify the required MRP area in the scope of planning.
During single-item, multi-level planning, the system plans the selected material in the MRP area entered. In addition, the system takes into account planning file entries from other MRP areas, for example, if the material is to be procured using stock transfer.
During single-item, single-level planning, the system plans the selected material in the MRP area entered only.
Structure
You define the MRP areas in Customizing for MRP. You can thereby assign the following to an MRP area:
one or more storage locations (example: you want to carry out planning for a particular assembly line and therefore assign a production storage location to the MRP area)
a subcontractor.
You assign the various MRP areas to the materials in the material master. For this, you create an MRP area segment for a material for every MRP area, in which it is used. In this MRP area segment, you can define MRP parameters such as, for example, the lot size or MRP type. This allows you to plan the material differently in the MRP area from how you plan it in the plant MRP area.
MRP with MRP areas for the material is not activated until the material has been assigned to an MRP area. If you have not assigned a material to an MRP area, that is, you have not created an MRP area segment in the material master, the material will continue to be planned in the plant MRP area only. If you have assigned an MRP area to it, the system can plan it in the plant MRP area and in the assigned MRP area.
Integration
You can carry out material requirements planning for MRP areas using all MRP procedures and all lot-sizing procedures.
You can also carry out an independent material forecast for MRP areas using your own parameters.
The material consumption values are updated separately for each MRP area.
A separate ATP check is carried out for each MRP area.
If several storage locations belong to an MRP area, the system can also carry out a check at two levels, that is, at storage location level and at MRP area level.
Example: Subcontractor
You can also carry out planning for components to be provided in subcontracting using an MRP area by defining an MRP area for every subcontractor and assigning the components to be provided to the MRP area of the subcontractor. You therefore plan the requirements to be provided for these components for one subcontractor separately from all other requirements (see Planning for Components to be Provided in Subcontracting).
Depending on the requirements situation, the system creates either stock transfer reservations from the plant to the stock of material provided of the subcontractor or it creates purchase requisitions within subcontracting/third-party order processing, according to the special procurement key settings.
Implementing MRP Areas
Implementation Options
The main reason for you to implement MRP areas is if you would like to plan materials, which are required in different shop floor areas, storage locations or by subcontractors, separately from one another.
As soon as you have activated materials requirements planning with MRP areas, this type of MRP is active at client level, that is, MRP will be carried out in this way in all plants.
Material requirements planning with MRP areas cannot be reversed.
Process Flow
You can implement material requirements planning with MRP areas in three steps:
You convert the existing planning file entries at plant level to planning file entries at MRP area level.
During the conversion, the system creates a plant MRP area for every plant as a background job. This, however, will not affect your planning. The processes in material requirements planning and the planning results remain unaffected.
The conversion is also useful even if you do not work with MRP areas, but still have to plan for several plants, as the new planning file improves system performance during the planning run.
You activate MRP with MRP areas in Customizing for MRP. This causes the MRP area field to appear in the applications of MRP and in related areas. When you enter the plant number, the system automatically fills the field with the number of the plant MRP area. The number of the plant MRP area is the same as the plant number.
This does not affect the planning run as the plant MRP area still corresponds to the present plant.
You define an MRP area, for example, for a storage location. You then assign the materials that are to be planned for this storage location, by creating an MRP area segment in the material master.
Materials requirement planning for this storage location is then carried out separately. The storage location stock is no longer included in the available stock of the plant MRP area. The receipt and issue elements of this storage location (MRP area) are also not taken into account in the plant MRP area. They are only taken into account in the MRP area of the storage location.
If you have already worked with storage location MRP the system still carries out storage location MRP even after the activation of MRP areas. You need to decide in principle whether you want to continue using storage location MRP or whether you want to create MRP areas for the storage locations that are planned separately. It is not possible to simultaneously plan a material using storage location MRP and an MRP area for the same storage location.
If you decide to use MRP areas, you should then try to convert all storage locations that are planned separately to MRP areas in one step. Before you assign the material to an MRP area, you must remove the MRP indicator, which is located in the material master at the storage location organizational level (view MRP 4) in the screen area Storage location MRP.
Even if you have defined MRP areas in Customizing, the system plans the materials in the plant MRP area until you assign the MRP areas to the materials.
Only the assignment of one or more MRP areas to a material, by creating MRP area segments in the material master, actually cause changes in the material requirements planning.
Hope this helps.

Tejas

STO to MRP Area

We have a scenario in which stock is kept at depots across various locations. We have depots created in SAP as Plants and when requirement is generated at Depot, system checks the stock at depot and pass the requirements to Manufacturing plant if stock is not sufficient at Depot in the form of a stock transfer PR. Up to this system is working perfectly fine.
Within plant, we have different MRP Areas for material planning. The requirement is that the PR that is generated for STO, should be able to pass the requirement to an MRP Area (after stock check on the same MRP Area) based on storage locations. Here is where, the scenario starts to fail. The system is passing the requirement and checking stock only at plant level.
I have tried using Stock determination rules, but I cannot utilize stock determination group of one plant to another in the system.
One option that came to mind was manually putting the storage location in the planned order, but with that, the stock checking fails.
While converting planned order to production order, the system accesses the right MRP area, although the material balancing / planning is happening at plant level
Please guide on how I can overcome this problem.

Hi,
what i understood is , you are having receiving plant and issuing plant. In receiving plant u are having number of storage location MRP area. Then using stock transfer from plant to MRP area, you want to transfer the stock from issuing plant to MRP area storage loaction of receiving plant.
i hope you have maintained the special procurement key for "Stock transfer from plant to MRP area" in MRP area segement of material Master.
As per this stock transfer PR will be generated at MRP area storage location if enough stock is not avilable.
But your problem is PR is not getting assigned in storage location MRP level , but it is in Plant level. Am i correct.
As per my knowledge, the receipt elements (PR) are assigned to MRP area, using the receiving storage location, which the system determines during the planning Run.
then it checks whether the receiving storage locations has been determined belongs to MRP area or not, if yes means the system assigns the receipt element (PR) to MRP area, otherwise (if not same) it will assign the PR to plant level.
you should have given receiving storage loactions any of the below three area.
1.as receiving storage location for repetitive manufacturing in the production version
2.either as production storage location (in-house production) or as external procurement storage location (external procurement) in the MRP area segment of the material master or in the material master itself
3.as receiving storage location in Customizing for MRP in the IMG activity Define MRP areas
<b>in your case the receiving storage location has been dermined by MRP run might not be same as what you have given in Custoomizing For MRP or in MRP segment.</b>
please check both are same... if my assumption is correct means follow otherwise ignore.

MD04 - Subreq - Storage location MRP area

Hi all,
I have an issue of Subreq in MD04 which is not assigned to the the good MRP area.
I'm explaining :
Business process
   -> I work with a subcontractor
        case 1 : either I buy raw material to be processed and delivered it directly to my subcontractor
        case 2 : either I send raw material from my physical stock to my subcontractor
   -> I create subcontracting purchase order with indication as components, the raw material.
   -> In case of the components are already in my subcontractor (case 1), the reservation (Subreq) should not consume my physical stock.
   -> In case of the components are in my physical stock (case 2), the reservation (Subreq) should consume the physical stock.
Solution choosen
Then I decided to create a storage location MRP area : "EXTERN" as External.
I assigned a storage location "EXT" to this MRP area.
I assigned this MRP area to the material in MRP1 / MRP Area.
In the purchase order, in the components popup,
For case 1 : I assigned "EXT" as Prod.Stor.Loc and Supply area
For case 2 : nothing special is filled
Issue
For the case 1, althought I assigned the storage location "EXT", the Subcontractor Requirement is not attached to the good MRP area.
WHY?
Remark : I didn't use the subcontracting MRP area because I would like to have 2 cases : case 1 & case 2.
Thank you in advance for your help about this problem which make me nervous !

Hello Catherine
Your system is working as designed. The following note explains the system design in more detail:
503497 - Subcontracting and MRP areas
Take a look on the relevant information provided by this note below:
Reason and Prerequisites
The most important point to understand the system behavior is the fact that the withdrawal of the (subcontracting) component is generally carried out during the goods receipt for an SC procurement proposalfrom the subcontractor stock that is managed at plant level from an inventory management point of view and that has no reference to a storage location at all.
This causes that subcontractor requirements can never enter a storage location MRP area, since you can later not post the withdrawal from this MRP area.
Thus SC-requirements always enter the SC segment of the plant MRP area or the SC-MRP area.
The SC MRP area in turn is supplied by stock transfer reservations from the plant MRP area or via third-party order processing through procurement proposals with goods receipt directly to the subcontractor. A supply through the materials planning from a storage location MRP area is not possible.
For the above reason, SC-requirements do also not carry any storage location, since the storage location does not have any control function at all for SC-requirements:
You cannot and you should not determine a storage location MRP area (see above), and the subcontractor MRP area is determined via the vendor of the procurement proposal, thus it is independent of the storage location.
See also Note 376050 on this topic that makes a modification available which prevents the deletion of the storage location in the subcontractor requirements, so that you can use, for example, customer-specific reports to analyze the storage location.
Please observe that the mentioned modification note 376050 only makes the storage location available on table RESB, so that you can use it on custom report. This modification will not make the storage location to be considered by MRP or on MD04.
