MRP Areas & shipments out of

Once I create an MRP area what is the best practice around making shipments in SD "from" the MRP area and not the plant it resides in itself?
Also if product is made within the plant iself the MRP area resides in vs outside STO ... what is the best practice on "transfering" the product from the plant to the MRP area (MRP area resides within the same plant).
Tim

Thankyou.
One last quesiton ... we are concerned about consuming "forecast" against the MRP area stock .... management is still asking how are sales orders to be entered "against" the MRP area so that forecast in demand plan is consumed?
As it sounds the order entry is as normal eg by sold to, material, date, etc. and only real difference is that when you create your delivery and pick you retrieve stock from the MRP area location eg 1002 which decrements stock from it.
As far as movements, it sounds like you can use location to location transfer postings to move stock between the plant locations and the MRP area location inside the plant and special procurement keys to move UB or NB Stock transports to the plant and then transfer to the MRP area.
Your thoughts or guidance are appreciated as we've never used MRP areas and can't find much info on these areas anywhere.

MRP Area and SA Schedule Lines

Hello All,
We are looking at using MRP Areas and noticed it can not be turned off once on (ECC 5.0). Given that, is the following true with reference to schedule agreements:
- Will seperate schedule lines be created for each MRP Area (same material)?
- Does the receiving storage location come from the material master or the MRP Area (Does it matter if it is a type 01 or type 02 MRP Area)?
- Is it possible to define differen't receiving slocs in a schedule line for a Plant MRP Area?
Thank you,
Jerry

Thank you Charlie,
The link is helpful however it doesn't come straight out and answer the questions - meaning there is a bit of ambiguity there.
It would be appreciated if you or anybody that is using MRP areas with schedule agreements is doing the above.

Jerry

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.

MRP area in Source list

Hello
Can anyone tell me how the MRP Area field (BERID) is maintained in source list (transaction ME01). In my system it is greyed out?
We are running MRP at MRP Area level and I was hoping that this field would allow me to maintain source lists at this level.
Thanks in advance for your help.
Kind regards
Sue

Hello Sue,
The MRP area field will appear if you are planning with MRP option 2 - Record relevant to MRP. Sched. lines generated automatically.
You can see help document below explaining this process:
http://help.sap.com/saphelp_47x200/helpdata/en/49/d8fe86df2c11d1a6a80000e83235d4/frameset.htm

Stock Transport from plant to MRP Area

I have been looking for explanation on how to handle replenishment of MRP area storage location stocks within a plant. We use Special procurement types but they are set up on for plants, not MRP areas. Can anyone explain how this works and the configuration to make it work? Were setting up a warehouse as an MRP area and need to replenish its stocks with MRP.

Aren't your questions answered in SAP online help?
Integration
The process is the same as for Storage Location MRP. In contrast to the storage location MRP, you can use all MRP procedures and are not limited to the reorder point planning procedure.
Prerequisites
In Customizing for MRP, you have created the special procurement key for Stock transfer from plant to MRP area for the plant in which the MRP area is located. You have defined the following parameters:
- Procurement type: F for External procurement
- Special procurement: U for Stock transfer
- Plant: Number of plant, to which the MRP area belongs.
In the material master, you have created the MRP area segment and assigned the special procurement key Stock transfer from plant to MRP area.
Features
During MRP, the system generates a stock transfer reservation for the material in the MRP area and a material reservation in the plant MRP area.
The external procurement storage location that you have entered in the MRP area segment of the material master is used as the receiving storage location. If you have not maintained this field, the system uses the receiving storage location that you entered for the MRP area in Customizing.
The actual procurement is processed by the plant. With stock transfer to the MRP area, you carry out the transfer posting for the material with reference to the reservation.
Standard procurement key 45 is for that purpose: plant: 1000 (V460A-WERKS), procurement key F; special procurement: U; plant: 1000 (V460A-WRK02).
So, in both fields you have to write the same plant as it is clearly written in SAP onilne help.
As SAP help says: a Stock transfer reservation is created. Using MIGO (A08; R09) you can post the goods movement by mvt 311 with reference to the Stock transfer reservation (MB1A is also good).
Why don't you test in in your sandbox system and you will see how it works.
(If you want to use STO (purchasing document type UB) in this process you have to go trough OSS note 599915)

In scope of planning ( md01), How to maintain MRP areas in scope of plg?

Hello PP members,
In scope of planning ( md01), How to maintain plant or MRP areas in scope of planning ?
What is the transaction code for maintaining plants or MRP areas in the scope of planning
I tried transaction code SAMP, Also went to SE93( Maintain transaction) for any related transaction codes for maintaining plants in scope of planning, it wasn't much help
Thanks for your time,
Thanks Again,

Hi,
we can use Total planning(MD01) for a single plant or use scope of planning to control whether total planning is to be carried out for single plant/sevaral plant/ for one MRP Area/sevaral MRP areas/ combination of plant and MRP Areas.
Steps :
1.Group together the plants which are to be planned in spro in --->Define scope of planning.(OM0E)
2. Define the scope of planning as 999 for ex and give description.
2. Now select that and Specify the sequence in which Plants and MRP Areas are to be planned,
3.Goto new entries and enter the plant as 1000/MRP Area as 1000 with counter 1 and plant as 1100 with counter 2 and save.
4.Execute the total planning either as online job or as background job.
5.The planning run has to be always started with paralle processing.
In SPRO in define parallel processing in MRP enter the destination for parallel processing for ex your server name and enter the no .of sessions as 1 and save.
6.Tcode MD01 enter the scope of planning group and selet the parallel processing and enter.
7. All the materials to be planned in the plant / mrp area will be planned now.

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

MRP Areas

I have defined MRP areas for our plant, however I'm not certain about the Conversion of the Planning File for MRP Areas if this will give me an option to convert specific plants or is it going to convert every plant?
Please help, thanks.

Hi
The first process in MRP is the checking of the planning file.The planning run and the scope of the planning run (which materials are planned in which planning run) are controlled by the planning file.
The planning file contains a list of all materials relevant to the planning run. As soon as a material master record is created with MRP data and a valid MRP type, this material is then automatically included in the planning file.
First you have to define the MRP area and Create MRP views for the Materials.Then automaticlly materials entered in Planning file.
If a material was created before the planning run was activated for a plant, you must generate an entry in the planning file for all materials in this plant that are to be included in the planning run.
This function can only be carried out in background mode.
Procedure
1.Starting from the MRP menu choose Planning ® Planning file entry ® Set up in background.
The initial screen for the setting up of planning file entries appears.
2.You can use a selection variant to plan the creation of planning file entries at a later date, or you can start the process immediately.
3.Once you have started the process, the system checks each material in this plant to see whether it is relevant for MRP. If a material fulfills the appropriate prerequisites, it is included in the planning file and either the net change planning indicator or the net change planning horizon indicator is set.

SPP and MRP Areas

Hi,
today we are doing all our ECC planning (MRP) on MRP Areas. No planning is carried out at plant level.
Is it possible to do the planning in SPP on the MRP Area locations instead of Plant locations.
We are considering where to perform our spare parts planning in the future and we are thinking of either using:
- ECC Flexible Planning
- APO Demand Planning
- SPP

MRP Area - ATP

Hi All ,
Please suggest me to workout for the below situation .
I have SLOC1,SLOC2,SLOC3,SLOC4 storage locations in the plant 1000. I want to check the SLOC1,SLOC2 stor locations only for the dependant complenents when I create a STPO in plant 1200 for header material(When creating STPO ,ATP carried out and checks for all components available in 1000 Plant) .And if I create Process order for the Header material , it needs to check the SLOC3 for the components availability .How can I map this one .Can it be possible with MRP area or any other solution is there ?
Thanks
Anil

Hi ,
PLANT 1200:
I have a material FERT1 in plant 1200 which is having a BOM component of HALB1(with special proc , stock transfer from 1000 plant ) .
PLANT 1000:
The FERT2 also having ghe BOM component of HALB1(no special procurment key) .
For the HALB1 the storage locations in the plant 1000 are SLOC1 ,SLOC2,SLOC3,SLOC4,SLOC5.
Now my requirements are as below
1) When Creating Process order in plant 1000 for FERT2 , it should check only SLOC1 & SLOC2 for the component HALB1 .
2) Due to dependant requirements of FERT1 in 1200 the STPO comes in for the HALB1 in 1000 plant , this time system needs look only on the stock at SLOC3 ,SLOC4 for the HALB1 in plant 1000.
3) When external requirements (Customer order) come in system needs to look at SLOC5 for the HALB1 in plant 1000.
So please suggest me the setup (I think it can be acheived with MRP area).
Thanks
Anil

Upload Forecasting parameters on MRP area level

Hi there,
Is there a way I can automate via Bapi or Idoc, the upload of the forecasting parameters on MRP area level.
The MRP area data is uploaded via IDOC /ISDFPS/MDMA but there is nothing foreseen for the forecast parameters.
Parameters that should be uploaded are DPOP-KZINI and DPOP-PRMOD.
Anyone an idea?

Dear Essam,
Please try the following procedure.
1. Create Plan in flexible planning --> MC93 (In this step you create Sales plan in flexible planning )
2.Sales plan verification transfer to active version--> MC8V (In this step you verify and transfer to active version)
3.Transfer sales plan to production plan -->MC8Q (In this step you transfer to sales plan to production plan)
4.Create Inactive Demand in Demand Management -->MD61 (In this step you create Independent Requirement which can be
simulative requirements. These requirements are set after analyzing sales forecast and production requirements together)
I hope it may help you out..
Feel free to ask.
Thanks,
Mohit

Regarding MRP Area

Hi All,
I would like to clarify a doubt regarding MRP Area concept.
1. MRP Area at Storage Loc level:
    What's the main advantage of this? i have gone through the documentation and
    understood how to configure it, but in a real scenario how its useful?
   For example: I have finished part: A which has components B, C & D. If i assign
   the stor.loc X MRP area to B & C not D and run the MRP on A, how system
   will react?
I am not able to understand how it's beneficial in real scenario?
Can some body help me out? i understand how it's useful for MRP Area for Sub-Con coz it will plan seperately for individual sub-con's..
Thanks and looking forward for your valuable hints and answers,
Chandra

The procedure is made clearer in the following example:
Assembly A is produced on production line 1. Components B and C, which are procured externally, are necessary for the production and are withdrawn from storage location 0001.
You can represent this situation in the system as follows:
You create an MRP area of the storage location type for storage location 0001 in Customizing for MRP. You assign the MRP area to storage location 0001.
You assign this MRP area to the components B and C in the respective material master records by creating an MRP area segment. You enter storage location 0001 in the Storage loc. for EP field in the MRP area segment, as this is also to be the receiving storage location for the components.
You create a production version for production line 1 in the material master for assembly A. In this production version, you enter storage location 0001 as the issue storage location for the components.
In the planning run, the system calculates the dependent requirements for components B and C and determines the issuing storage location 0001 using the production version. This enables the assignment of the dependent requirements to the MRP area for storage location 0001. When the system determines the procurement elements for B and C, it reads the external procurement storage location and uses this as the receiving storage location. This is also storage location 0001 so the procurement elements are assigned to the MRP area for storage location 0001. You can use this procedure to selectively plan the components that you require on the production line.
If you do not work with production versions, you can also enter the issue storage location for the components in the BOM, in the work center using the supply area, or in the Issue stor. location field in the MRP data of the material master record

MRP Areas Activation

Is there an option for one to only activate MRP Areas for a specific plant instead of activating for all plants in client?
Thanks.

MRP area activation is must if you would to carry out planning using "scope of planning"...in scope of planning you can group the plants or storage location or sub-contractors and run the MRP at one time. This you can do from MDBT/MD01 transaction in backgorund/online. This option for carry out plannning for MRP areas is not available with other transaction like MD02/MD03.
If you are working with plant level MRP from MD01/MDBT and not using the MRP area then you just have activate the MRP for plant from OMDU transaction. For this MRP area activation is not neccesary.
"MRP area Activation will not effect to the plant which are enabled for plant level MRP from OMDU transaction" Both are having different significance and importance.
Hope the above clarifications is clear.
If satisfy please close this thread or please inform for any more doubts.

MRP Areas and MRP

Hi I've created MRP areas, and expect to run MRP by MRP area, however, when I click on the drop down list beside the field MRP area in MD01 I do not get a list to select an individual MRP area. Is this right?
Thanks

Hi,
we can use Total planning(MD01) for a single plant or use scope of planning to control whether total planning is to be carried out for single plant/sevaral plant/ for one MRP Area/sevaral MRP areas/ combination of plant and MRP Areas.
Steps :
1.Group together the plants which are to be planned in spro in --->Define scope of planning.(OM0E)
2. Define the scope of planning as 999 for ex and give description.
2. Now select that and Specify the sequence in which Plants and MRP Areas are to be planned,
3.Goto new entries and enter the plant as 1000/MRP Area as 1000 with counter 1 and plant as 1100 with counter 2 and save.
4.Execute the total planning either as online job or as background job.
5.The planning run has to be always started with paralle processing.
In SPRO in define parallel processing in MRP enter the destination for parallel processing for ex your server name and enter the no .of sessions as 1 and save.
6.Tcode MD01 enter the scope of planning group and selet the parallel processing and enter. Hope the above points taken care and resolve the issue. Thanking you.
