MRP Plant Parameters

Dear Sir,
What are MRP plant parameters?Pl.Explain in details?
Points will be rewarded......

Hi,
The In this step, you can maintain all the plant parameters
1.Environment : Here you define the number ranges and the Backorder checking rule.
2.Master data: Like mrp controller,Speical procurment type and the Float - scheduling marging key can be configureed here
3.Conversion of planned order to productin order /Purchase requistion can be configure here
4. Planning urn : the selection of BOM ,Bom explosion,available stock etc and lot more can be configured here
Even though we have separate areas where we can define each of them separately here we can define most of the mRP related to single plant can be configured at this one.
Kindly let us know if this solves your query or if you are looking for anyother thing.

About plant parameters

hi
   everybody
    plz. tell me
wat is mean by plant parameters
whrer we maintain it
wat functions or values we maintain for this
wat it effects in SAP
   where we use it
   give details
   thanks in advance

Plant parameters carries important control parameters during MRP run
when you convert planned order into a prod order, the order type is copied from the plant parameters (oppq>>planned order coversions)
During MRP run ( if MRP run type is NETPL - Net Change Planning with Plannign Horizon), the planning horizon period
is defined in the Plant Parameters (OPPQ>>Planning Run>> Planning Horizon)
If Order start date is in the past, the system automatic does forward scheduling. In some scenarios if its ok to
have order start date in the past then you make setting over here (OPPQ>>Planning Run>> order start in the past)
Like wise, Special Procurements key from issuing plant are maintained in the plant parameters
SMK is also maintained in the plant parameters
Under the setting of Available stock, what type of stock you consider as Available stock ( like Stock in Transfer, Blockedd Stock, Restricted Use Stock) is considered as
available stock
The plant parameters are maintained in OPPQ
Also, Before maintaining MRP plant parameters, you need to activiate MRP for the respective plant in OMDU

Difference between To maintain and initial in plant parameters in MRP custo

Hi, Gurus,
Can anyone explain me about the difference between status showing
to maintain and initial in plant parameters in MRP customization
Thanks & Regards
sathyanarayana

Dear Sathyanarayana,
In T code OPPQ - Maintain Plant Parameters,it does not
mean we have to maintain a value in all the parameters
present under different tab keys.
IF you check generally MRP controllers,Floats,Number
Ranges,BOM/Routing Selection,Planning horizon,Available
stock these values will be maintained.
Some of the settings like Start in Past will be as Initial(not
allowed in the past).
IF you use some special procurement key,then that settings
has to be maintained.
I hope this will help you.

Difference between MRP group and plant parameters

hai friends,
please let me know, what is the main difference between the MRP group and plant parameters?,
what are the extra activities or features with one, when compare to the other?.
Edited by: Mourya.v on Sep 22, 2010 6:36 AM

Dear Mourya,
Why to assign MRP group? - If planning for each plant is not specific enough for your purposes and you would like to assign
control parameters that differ from the control parameters defined for the plant to certain material groups.
1.For all materials without an MRP group, the system uses the plant parameters that is the settings present in OPPQ, or the
entries in the initial screen of the planning run.
2.For all materials with an MRP group, the system uses the parameters recorded in the MRP group that is the settings in OPPR.
3.The MRP group is an organizational object that can be used to allocate special control parameters for planning to a group of
materials. You can maintain MRP groups if planning control per plant is not precise enough for your requirements and you want
to allocate certain material groups different control parameters from the plant parameters. For this purpose, MRP groups are
defined with these specific control parameters and are assigned to the material in the material master record (MRP 1 screen).
4.The MRP group, groups material from the material requirements planning point of view to allocate them control parameters for
planning.The control parameters include the strategy group, the planning horizon and the creation indicator for the planning run.

MRP SPRO- Plant Parameters-Direct Procurement

In the spro Plant Parameters-Direct Procurement
     Direct procurement only when creating production order
1     Trigger direct procurement in requirements planning
2     Direct procurement only when creating production order
3     Trigger direct procurement in requirements planning
Here 1,3 are seems to be same

hi
it looks like even 'blank' & 2 are also same similar 1 & 3..
but, options description clearly mentions the usage..

Plant Parameters

Hi ,
Pls tell me how to maintain plant parameters?
And who is defining this Plant parameters PP or MM?
Regards
Gitesh

Dear,
Plant parameter you need to define in OPPQ. As it is relevant to MRP so its PP person responsibility but it is integration between PP and MM like number range for Purchase requisition. availability check etc.
Hope clear your Doubts.

MRP Control Parameters

Hi All,
Pl. let me know where we define the MRP Control Parameters that gets displayed ,when we execute MRP(MD02), like
Create purchase req
1. purchase requisitions
2.purchase requisitions in opening period
3.planned orders
etc.
Normally we select these parameters while execution only.
I want to know where these parameters are defined.
best regards,
Kumar.

Hi kumaran
As Mr.Prashob said these are internal SAP setting. like this many settings are there. For example order type category is 10 for prod order. This also you cannot change, This will execute many functions internally in SAP.
If you want to set the indicators with respect to MRP group. you can ssign in MRP group setting.

MRP Control parameters(MD02)-Regarding.

Hi,
Can anyone explain me what values(MRP control parameters)should i use for MRP run.
For Eg for an 1.Inhouse produced material(FERT),
2.For externally procured (HALB) materials,
3.For Sub-Contracted items,etc
So that i'm getting proper planned orders or Purchase requistions.
what's the meaning for "Purchase Req.in opening Period"what's the meaning for opening period.
Thanks & Regards
Raj.S

For all materials type you can run withfollowing control parameters from MD02.
1) Processing key: NETCH
2) Create purchase requisations: Keep 1...by doing this for F parts MRP creates PR and for all E parts MRP creates Planned orders...This will work according to procurement type. If you keep 3 "created planned orders: then MRP created only Planned orders..no PR will be created.
3) Create scheule lines: Keep 3...if schedule lines are mainatin then scheudle lines will be created..otherwise no impact.
4) Create MRp list: 1... to see the MRp results.
5) Planning Mode: 1..This is better to improve the system performance . if you new data eevrytime then keep planning mode 3.
6) scheduling type: 1...Basis dates scheduling if you are not working with capacity planning.
If you are maintaining scheudle margin key in MRp2 view with opening period for example 10 days and in MRP control parameters :create PR in opening period" then MRP creates PRs only in the opening periods of the schsdule margin key if the opening dates of the PRs are falls within these 10 days. Otherwise MRP creates planned orders..later you can convert these Planned orders into PRs.
If helpful rewards your points.

Field selection for plant parameters

In plant parameters - in external procurement tab-i want to change field selection for Account assignment for non valuated materials field to optional,.Presently it is required field
can sombeody tell me path

Hi
Go to SPRO>Production>Material Requirements Planning>Plant Parameters> Carry Out Overall Maintenance of Plant Parameters and execute. (Transcation OPPQ)
Select Maintain and give the plant
Select External procurement Tab and select Unknown account assignment.
But, you need account assignment for non-valuated material for external procurement.
Hope it solves your issue.

Consequences of maintaining Plant Parameters

Dear All,
I would like to know that what could be the consequences for maintaing plant parameters under ' Inventory Mangement and Physical Iinventory ' for the plant which is copid from the existing plant for which plant parameters have not been maintained.
This is what SAP is saying (the extract is from spro implementation guide)
Plant Parameters
In this step, you make the general plant settings for
Inventory Management. All settings are also contained in the individual steps of the Implementation Guide for Inventory Management. If you want to allow negative stocks in your plant, you have to set the XBKNG indicator in addition to the settings in this step. To maintain this indicator, choose the step Goods Issue/Transfer Postings -> Allow Negative Stocks in Customizing.
Recommendation
SAP recommends that you do not make the plant settings here, but in the individual steps of the Implementation Guide, so that the settings here are not without a context. Dependent settings are not contained in this step.
Activities
If you have created a plant in the enterprise structure using the Copy plant function, you do not need to make any settings.
If you have created a plant manually, you have to create a new entry for the plant parameters.
What should I do? Should I go for it or not?
Thanks and regards,
Saleel Kulkarni

Hi,
If you created a plant by copying the standard plant 1000 , the plant paramaters foe inventory management will automatically come to your newly created plant. N o need of creating parameters separately in inventory management. If you create the plant without copy function you have to maintain plant parameters. I hope this will help you. Thanking you.

Plant Parameters in GR Conversion

Hi All,
During GR conversion, we got the message,
"Plant parameters not maintained"
Any guess which plant parameters will have effect on GR conversion?
Thanks

How did you create a Plant. I mean to say Whether you have created a Plant with reference to another Plant. If this is the case Plant parameters will be automatically copied.
If you created a Plant using Create function You should maintain All the Plant Parameters in the SPRO -> IMG ->Mat Mgmt -> Inventory Management & Physical Inventory -> Maintain Plant parameters.

Carry out plant parameters

Hi Gurus ,
In SPRO -> MM-> Consumption based planning ->plant parameters -> carry out overall maintenance of plant parameters.
I am copying the plant parameters from plant 'X' to plant 'Y ' . But both of these plant are from different company codes .
What is the impact if the two plants are from different company code ? what changes do I need to do in plant 'Y' parameters after copying ?
Please explain in detail
Regards,
Saurav

Here is used to specify plant parameters for the material requirements planning, I also don't see the potential impact which might caused by different company codes.
In
Enterprise Structure
Definition
Logistics - General
Define, copy, delete, check plant
You could copy plant refering to template, which has company and plant's combination.

MRP Group Parameters VS Plant Parameters

Is working with MRP group mandatory in MRP? If we do not maintain MRP group do we lose any advantage?

Geetika,
You lose some flexibility.
OPPQ settings are plant wide. That means that everything you set here will affect all MRP materials that are extended to that plant.
OPPR allows you to have differing settings within a plant. For instance, you may have different types of production orders you wish to use, depending on the material. You may wish to use different Production order availability checks within a plant. You may wish to allow some orders to start in past, but not others. You may wish to have differing planning horizons or different scheduling horizons, depending on the material. These differences can all be accommodated within one plant by use of MRP groups.
I have seen plants set up both ways. It really depends on the requirements of the business. I don't make that decision until all the client's requirements have been gathered, and I am deciding how complex the solution needs to be.

PP- Authorization check to set plant parameters

Hi team,
I have created Ztransaction to maintain some plant specific parameters. I have assigned this new ztransaction to single role. Currently i have 12 plants and the user is requesting that only the respective plant users can able to maintain the entries for only the respective plant and not for all plants.
How to implement this?
your input will be very much appreciated.
thanks
psk

Hi,
As per my undestanding it's not fesible to define user-specific roles in SAP.
You can have SAP process-specific roles like purchasing/production/sales etc.
Each transaction related to above processes will have a authorization object linked to it which further will have different parameters on which we restrict the authorizations to users like plant/pur org/sales ord etc.
So looking at your scenario, define Plant specific roles with required authorizations and assign only roles of Plants to which you think that a user should get access.
For more inputs talk to your basis consultant.
Hope it will help.

Anup

In plant parameters how the start date in past will be applicable for order

Hi All,
Can any one explain me in detail start in past for plant parmeters (OPPQ).
Regards
sailendra

Hi,
Start date of order proposals allowed in the past
This indicator defines that the system does not automatically switch to forward scheduling if the order start date lies in the past for determining the basic dates. With this indicator, backward scheduling is always used to determine the basic dates, even if the start date lies in the past.
e.g Bacward scheduling type, Today date is 08.06.2009
If u give basic finish date say 25.06.2009,and system propose you basic start date in 06.06.2009. That is 06.06.2009 is lies in past date.In this case system propose you forward scheduling.Means order basic start date is 08.06.2009 .If you don't want to system propose you for forward scheduling tick mark Start in past in OPPQ.
Hope this clear you.
Regards,
Raja.
