SAP PM-MRP RUN

Dear All,
Can you tell me How to run MRP in sap PM & How it is configure.
Thanks & Regarsd
Vishal

In Spare Parts or materials which ever used in PM orders, MRP views should be maintained. There is no specific MRP run for PM. MRP is for all the materials under the plant.
Materials availability check can be done at the time of saving the order & releasing the order. Based on the material availability, you can control order release.
For stock items, reservation will be created. While running MRP, these reservations also will be considered if stock is not available. For non-stock items, PR will be created directly from PM order.
Material Availability check config:
IMG => PM & CS => Maintenance & Service Processing => Maintenance & Service Order => Functions & Settings => Availability check for Materials
Under that, you can find different config. This availability check will be done at plant & order type level.

SAP PP MRP Run Results

Hello,
We are in the phase of implementing SAP. I am working on PP module. When we run the MRP (MD01 or MD02) for a finished product, the system will not give any exception message on the planned order level for it if any of the components is not available at the suggested start time. In another words, the system will not suggest to postpone the finished product planned order date to match the last component arrival date.
Any one can help in this regard.
Best Regards,
Fadi

Fadi,
I am afraid this is standard behavior.
This condition (components too late) is not an ECC MRP exception, so it is not contained in MRP output. MRP is not designed to push out orders when the components of the order are not available. ECC MRP only works from the top level of the BOM downward, level by level. When it is creating messages for a particular plant/material, it has not yet done the MRP of the the lower level components, and so has no way to determine whether or not they may be late.
If there is a mismatch between the component supply order and the dependent demand of a higher level order, MRP should give a rescheduling message to the COMPONENT orders ('bring process forward'). From this message, an astute planner might intuit that he should reschedule the higher level orders.
If you need bottom-up rescheduling, you will have to go to APO. SAP ECC PP doesn't directly support that concept.

When SAP run mrp, it could only identifiy first 9 characters as material?

Hi experts
In SAP, Could we set when we run mrp, sap will only check the first 9 chars as mateiral number ?
eg: material 12345-67890 and 12345-6789, Could sap consider it as same material ? If there is any configure for this ?
Thanks
Alice

Hi experts
Our purpose is we need setup two material number like aaaa-aaaa1 and aaaa-aaaa2 for same part but from different localization source.
Since they are same part , if mrp could only reconginze the first 9 character as materail number to run requirements ? what does it mean planning material ? It could set the first 9 character as planning material different from the normal materail ?
Thanks
Alice

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

SAP PP - MRP Strategies-

Hi,
Can anyone reply as to which MRP Stategy to be used so that STO's are not considered during MRP run at finished/semifinished material level or is there any customization which will exclude STO's comletely for MRP run.
thanks & regards,
tss1754

Hi,
Standard MRP does not exclude the STO as it also impact the stock/requirement situation.
If you'd like to achive your requirement, you may consider to use a specific storage location that is excluded from MRP (You can define it in MMSC for certain storage location with material) or there is a BADI MD_CHANGE_MRP_DATA. It allows to change MRP relevant data for MRP elements during the planning run and during the creation of the stock/requirements list.
I hope this helps.

Tibor

Sap pp- MRP execution

How can we carry MRP execution process for several plants under same company codes?

Hi,
Defining Scope of planning, it is possible to run MRP for several plants.
To create scope of planning use tcode OM0E.
Insert all the plants which you want to run MRP.
Run MRP by tcode MD01.
In that screen make tick mark in define parellel processing.
In SPRO give server name in parellel processing.

SAP MRP Results

Hoping to find some help here from some knowledgeable experts:
Situation: Trying to create an program to extract MRP results out of SAP(basically what you see in MD04).
Question 1: Does anyone know a way using the ABAP interface to determine if a part has "activity" (has supply or demand or onhand) prior to performing a bunch of expensive queries? I really only want to extract the parts that have this but I can't figure out how to do this efficently.
Question 2: Trying to find an easy way to understand what SAP considers the a) Total active demand for a part is, b) Total active supply for a part is and c) Ending inventory balance based on MRP results. Does anyone know of a way to efficently determine this on a part by part basis?
Thanks in advance for any help anyone can provide me!
Regards,
Kris

Kris,
MD04 does not extract MRP results, MRP results are extracted and displayed in MD05. MD04 only shows you the 'current' situation.
Question 1: Does anyone know a way using the ABAP interface to determine if a part has "activity" (has supply or demand or onhand) prior to performing a bunch of expensive queries? I really only want to extract the parts that have this but I can't figure out how to do this efficently.
I am not aware of a single and easy comprehensive way to determine whether a material has supply or demand elements. FYI even SAP's MRP does not attempt to make this determination. Instead, it either reviews ALL materials (regenerative MRP) or it uses the Planning file (Net Change MRP) to determine which materials have had activity since the previous MRP run.
Question 2: Trying to find an easy way to understand what SAP considers the a) Total active demand for a part is, b) Total active supply for a part is and c) Ending inventory balance based on MRP results. Does anyone know of a way to efficently determine this on a part by part
MRP uses different methods to determine supply and demand, depending on the type of planning being used. Planning is dependent on MRP type and Planning Strategy. MD04 uses different but related methods from those used by MRP. Check out some basic online help about
MRP Planning Process

I don't know what your business requirements are, but MRP Calculations and MD04 calculations are some of the more involved within SAP MM and PP. Exactly duplicating the results of either of these tools IN ALL SITUATIONS is a daunting task. You should consider cloning MD04 or MD05 and then modding the result to meet your business requirements. Another possibility is to make use of the userexits within MD04/MD05 to alter the display to meet your requirements.

Dropped sales order report from SAP

Team,
There is a specific requirement regarding sales order..to analyze the dropped /undelivered order for a period.
Currently we are entering only those sales orders in the system which can be shipped/delivered to customer..all those SOs which can’t be delivered are not entering in system.
It is because if we are entering those orders in the stem, MRP will consider those orders for planning.
Now we need to include all the sales orders in SAP and MRP should only consider such orders which can be shipped. Can we do it in the system?
Thanks for the advise.
Regards,
Vijesh

MRP should only consider such orders which can be shipped. Can we do it in the system?
At what stage, you will come to know that sale order can be shipped as planned? Nevertheless, you can either change the MRP Type in material master to ND or change the schedule line category in sale order to CN so that system will not consider such of those materials for MRP. You have to decide which one is better but I would prefer the second one as changing the master data quite frequently is not recommended.

MRP calculation

Do SAP B1 MRP calculation able to calculate production lead time until min?

what i mean is that
whether in SAP B1 the MRP calculation will be able to calculate the production lead time until the level of minutes? since now in item master, the lead time column only can key in by days.
Thank you

MRP for FG not looking at Raw Material

HI all,
I'm running MRP for finished goods material against my production plan (created in MD61).   The material has a BOM component but when I run MRP for the FG its not looking at BOM component to consider raw material) availability and thus proposing dates solely based on the Production Plan and not any other requirements.
It simple creates the planned orders based on the production plan entered into MD61. The dates for the planned orders don't take into consideration that on the suggested Production date there is not enough raw material to actual produce the product.
The Production plan does drive requirements to purchase the raw material but the dates are not neccessarily correct to get product to the warehouse on time for production run.
FG set up:
RP Type:                                PD - MRP
Lot Size:                                 EX u2013 Lot-for-lot Order Quantity
Safety Stock:                         125 - EA
Availability Check:                   02 u2013 Individual Requirements
Procurement Type:                   E - In-House Production
In-house Production:                 1 - days
Planning Strategy:                   10 u2013 Make-to-stock production
BOM / Raw Material set up:
RP Type:                                PD - MRP
Lot Size:                                 EX u2013 Lot-for-lot Order Quantity
Availability Check:                   02 u2013 Individual Requirements
Procurement Type:                    F - External Purchased
Pland Del Time:                         3 - days
GR Process time                       1 - days
Planning Strategy:                   40 u2013 Planning with Final Assembly
How do I get the MRP for the FG to not only create the planned orders from the production plan but also take into consideration raw material availability?   Thanks for your help!!

VC,
I need to the PlndOrd date for FG to take into consideration raw material availability...otherwise it's pretty useless to the site.
I guess you are unfamiliar with the workings of standard MRP. MRP in ECC as delivered by SAP will not support this requirement.
There are a couple of assemble to order strategies that may be suitable for you, if all of your RM materials exist in the FGs BOM. Strat 81 and 82, which are intimately linked to the Sales order ATP check. These strategies are not compatible with FGs forecasts.
http://help.sap.com/erp2005_ehp_06/helpdata/EN/41/19206a45fd11d188ff0000e8322f96/frameset.htm
In SAP ERP, MRP just does not check the availability of components during the MRP run. The Net Requirements calculation of a component part (which is the closest concept within MRP to an Availability check) takes place ONLY after all parent parts are completely planned, and all parent part planned orders have been already been generated and saved. In effect, when MRP is running, information is neither gathered nor considered as to what the planning situation will be for the components.
APO has several solutions that, depending upon the detailed requirements, might provide a solution. A common one is to first run an MRP type heuristic, to create planned orders for all the shortages, and subsequently run a 'Bottom-up' scheduling heuristic to bring supply and demand dates into alignment, based upon pegging information. ERP does not have this functionality.
Of course, SAP ERP is infinitely modifiable. If you have enough time and money, you can write custom code that will torture ERP into filling any Business Requirement.

MRP type V1

Dear All,
Please let me know the settings in material master for MRP type V1. I have enetred lot size as MB. Minimum lot size 200, reorder point 100. After MRP run we received purchase requisistion of 200. Then we created sales order due to which now there is requirement of 300 pcs for that material but system is not considering the shortage of 100 pcs. please let me know the reason.
Regards,
SAP CONS

Dear
MRP Type V1 consider the re-order point quanity and generate the requirement after MRP run .In your case , it frist consider the Re-Order point , then Minimum Order Quantity and do not consider the Sales Order .But it will also consider the Sales Order as demand on priority if the Sales Order Quantity is more than the Re-Order Point .
Let , say you do not have stock .U have Sales Order Quanity 2000 pc and re-order point in Material Master 1800 pc , Mini Lot Size 1000 .If you run MRP-MD03, the result will be based on the MRP Type-V1 considering the re-order point qty after calculating Net Requirement and generate PR with 1000PC and rest .
More over , you are using MB-Monthly Lot size , it will club all the Monthly requirement as PR in the Planning Horizon based on your MRP run date .
So if you use , MRP Type PD , i hope it will consider your Sales Order Requirement along with your PIR

Preventing MRP run if Sales order is blocked

Hi
Relating to SAP note 744484. Is it possible to setup a similar outcome but with
this dependant on the credit block.
In other words we wish to prevent MRP generating a planned order once the credit
block is active but allow planned orders to be generated once the block is removed. This is to cater for replenishment orders should losses occur.

please check this link.

MRP Run for Multiple plants

Hi Guys:
IN SAP R/3
My client has requirement to merge planning of material for multiple plants and run the MRP under one head plant.
For example:
Plant : 1000, 1001, 1002, where plant 1000 is a head plant who had authorization to perform MRP run.
if I run MRP Sepeartely:Each plant has below requirement for one material number (M1)
Plant 1000 : 3 EA
Plant 1001 : 2 EA
Plant 1002 : 5 EA
Instead of running MRP per plant, my client needs to run MRP for multiple Plants that Consolidate total requirement for all plants.
and generate PR--->PO , In the PO, M1 should be delivered to 3 different plant locations by vendor and Po Will be issued from Head Plant 1000?
Is there any Report in SAP , Where MRP Controller can See Requirements from Different Plants @ Central Purchasing level after one Multi Plant MRP run, So that he can decide on how much to allocate to each plant?
Thanks for help
Thanks
Sweth

Hi,
If u want to perform the MRP in one plant for all the plant requirement is depends on the bussiness process.
You can try the following scenario:
Planning in one plant nd production in other plant - Respective master data and special procurement have to maintain.For
further clarity please follow the below link
http://help.sap.com/saphelp_46c/helpdata/en/f4/7d3f9344af11d182b40000e829fbfe/frameset.htm.
We can evaluate the PR and PO by providing the authorisation object for the multiple plant to the respective users.
Revert me back in case of clarification.
Thanks
