MAterial Resource Planning (MRP)

Hi,
Can you tell me what is Material Resource Planning (MRP)? How & why is it used in SAP MM?
Regards,
Krutika

hi
it is Material Requirements Planning
Material Requirements Planning (MRP) enables you to plan material requirements for a manufacturing or procurement process.
MRP calculates gross requirements for the highest Bill of Materials level based on sales orders and independent demands. It calculates gross requirements at the lowest Bill of Materials levels by carrying down net parent demands through the Bill of Materials structure. The dependent levels might have their own independent demands, such as sales orders and forecasts.
The results of the MRP run are recommendations that fulfill gross requirements by taking into consideration the existing stock levels and existing purchase and production orders. The MRP run also takes into account defined planning rules for Order Multiple, Order Interval, and Minimum Order Quantity.
Recommendations are back scheduled by the defined lead time to arrive at the requirement dates for their own components.

Question about distribution resource planning in pp module

hi, my all respected sir,i want to ask question as below
1) what do you mean by distribution resource plannning and what are steps occour in this planning?
2) what is the difference between drp and mrp?
    thank you , all of you

Hi,
Distribution Resource Planning (DRP) is a method used in business administration for planning orders within a supply chain. DRP enables the user to set certain inventory control parameters (like a safety stock) and calculate the time-phased inventory requirements.
DRP uses several variables:
     the on-hand inventory at the end of a period.
     the backordered demand at the end of a period.
     the required quantity of product needed at the beginning of a period.
     the constrained quantity of product available at the beginning of a period.
     the recommended order quantity at the beginning of a period.
         DRP needs the following information:
     the demand in a future period.
     the scheduled receipts at the beginning of a period.
     the safety stock requirement for a period.
     the on-hand inventory at the beginning of a period.

Material Requirements Planning (MRP) is a software based production planning and inventory control system used to manage manufacturing processes. Although it is not common nowadays, it is possible to conduct MRP by hand as well.
An MRP system is intended to simultaneously meet three objectives:
     Ensure materials and products are available for production and delivery to customers.
     Maintain the lowest possible level of inventory.
     Plan manufacturing activities, delivery schedules and purchasing activities.

Cross Plant Planning- MRP activation indicator turned after the creation of Material code

Dear Experts,
Working on Cross plant planning, where 1001 Production plant will stock transfer material to 8 different plants.
Right now, only 10001 plant had MRP and planning file entry ticked in customizing OMDU.
The other 8 plants have Materials codes created and MRP views extended but no MRP activation is ticked.
Now, to have Cross plant planning MRP set, I have done necessary configurations, Scope of Planning, Special Procurement 40, and parallel processing is configured. All master datas are set properly. Tested few scenarios in IDES, working fine.
If my understanding is clear, than I thin I need to run MDAB, activation of planning file and MDRE, Planning file Consistency Check, because MRP will run in background?
Is this correct or something more needs to be done ?? Please suggest
Please also tell what is the use of MDRE t code.
Best regards
Shailesh

Hello Shailesh
MDAB (RMMDVM20) is at plant level, you need to create different variants as per your plants
Create a variant for the new plants and then schedule a job for these variants.
Check customizing transaction OMDU -> set up planning file
entry and consistency check of planning file entries.

What is Material Requirement Planning

what is Material Requirement Planning since i am a beginner in Supply chain management

Material Requiremnts plan and master schedule (MRP) answers two quisitions:
1. How mauch you need to supply (Make/Buy).
2. How much resource Hours needed to produce.
MRP is an unconstrained, and infinite planning engine. this means, if you have a demand (Sales order/Forecast), the planning engine recommend actions to be done based on demand due date only regardless of capacity or material availability, and it gives you exception messages to take action; as a planner; regarding anything that may violate satisfying the demand in that due dates.

Dear
Distribution Resource Planning
Distribution resource planning provides a framework for determining the need to replenish
inventory by:
Linking market requirements with manufacturing and demand management
Relating current inventory positions and demand forecasts to production scheduling
Matching material supply to manufacturing demand, and customer demand to product
supply
Process Flow
1. You define all nodes in the network including plants, distribution centers (DCs),
warehouses, and stock transfer points using the Distribution Network tool.
2. You set up the material master record for each node. In MRP 4 of the material master
record, you must define the deployment strategy for each material (the fair and push
distribution options) as well as deployment horizon (push horizon). For the push horizon,
enter the number of days for which the system considers the ATD quantity and any
additional quantity produced. Any quantity produced beyond the push horizon is not
considered in the deployment calculation.
3. To calculate an available to deploy (ATD) quantity, use the availability check rule, DE, in
Customizing, u2018Carry out control for availability check.u2019 The availability check and the
deployment checking rule, determine the MRP elements that are used to calculate the
ATD quantity.
4. You create a forecast for each DC; for example, a sales forecast.
5. You transfer the forecasted data to Demand Management. The system creates
independent requirements.
6. You perform a DRP run in each DC and in each supplying plant. The DRP run considers
the quota arrangements defined in the network, available stock, sales orders, and
independent requirements.
The DRP run in the DCs creates releases for stock transport requisitions in the
supplying plants.
The DRP run in the supplying plants creates planned orders for production.
7. You convert planned orders into production orders for manufacturing.
You run deployment to produce stock transport orders for distribution of stock from the supplying
plants to the DCs.
Distribution Requirement Planning :
Generates stock transport requisitions between locations.
Accounts for time-dependent safety stocks when the replenishment stock is calculated.
Initiates planning runs in a net change procedure or in a regenerative planning mode
Deployment
When demand is greater than supply, deployment calculates a fair share quantity based on the available-to-deploy (ATD) quantity and requirements in the distribution centers to be supplied.
When supply is greater than demand, deployment calculates distribution of stock using pull or push logic within the distribution network according to planned requirements.
Generates stock transport orders from suggested orders in the DRP plan.
Prioritizes quantities supplied based on requirements types (customer order, forecast, and safety stock).
Multi-Sourcing Using Quota Arrangements
Lets multiple plants supply a percentage of the material required by a single location, which makes it possible to prioritize the deliveries made by plants and to specify maximum delivery quantities for particular time periods.
Represents simple capacity constraints, and combines the percentage-based and maximum quantity approaches.
Lets you establish minimum, maximum, and rounding profiles for lot sizing within the network.
Lets you change the distribution network at future dates.
Lets you offset delivery times for specific items from the sourcing location to the replenishment location.
Single-Sourcing Using Special Procurement Keys
Hope this above details will be useful for your requirement .

Running DRP
Purpose
In DRP, during the net requirements calculation, the system compares available stock and the
scheduled receipts from the supply source with planned independent requirements and incoming
sales orders. If there is a material shortage (available stock is less than the quantity required),
the system creates an order proposal.
The system calculates the quantity recorded in the order proposal (in the form of a requisition)
based on the lot-sizing procedure you specify in MRP 1 of the material master record.
The system also schedules the order proposal. Delivery and release dates are determined from
the transport time and time associated with goods receipt processing.
The system can process DRP for the whole supply chainincluding the production plants. DRP
includes production and purchasing into the planning process for the production plant.
Prerequisites
In order to perform a DRP run, you must:
Set up a distribution network, including identification of quota arrangements and lead
times.
Define MRP parameters in the material master record for all the materials in the
distribution network.
Process Flow
1. You schedule the DRP runs for your network in the same way you would schedule an
MRP run.
2. You perform the DRP run:
A DRP run on one material is the same as single-item, single-level planning in the MRP
run. Because the deployment plan involves finished goods, there is only single-material,
single-level planning of individual materials without explosion to lower levels.
A DRP run on one plant is the same as total planning in the MRP run. Single-plant
planning involves planning all the materials in a certain location that are relevant for
requirements planning.
A DRP run using mass processing allows you to process several locations at once so
that the whole supply chain is planned.
3. You use net change planning to plan only materials that change relevant to distribution
requirements planning since the last planning run (for example, change in a sales order
quantity or date). Net change planning improves system performance for large, complex
distribution networks with many materials. If a material is changed in a way that is
relevant to the planning run, it is given a net change indicator, and included in the next
planning run.
Performance can be improved even further by using the change planning within the
planning horizon. Only changes relevant to requirements planning that fall within the
user-defined planing horizon are included in the planning run. To keep the planning
results up to date, perform a total planning run regularly (weekly or monthly).
for planning. Regenerative planning is performed in the implementation stages.
4. If you are using mass processing, determine the sequence in which the series of DRP
runs must be executed.
Result
The information resulting from the DRP runs includes purchase requisitions and scheduling
agreements. Use these to plan how to supply the distribution centers in your network. The DRP
run in the DCs creates releases for stock transport requisitions in the supplying plants. A DRP
run on the supplying plants creates planned orders for production.

Creation Indicator in PR: B Material Requirement planning

Hi All,
I am facing an unusal scenario.
User is claming that PR is getting generated for a material after running the MRP, even there is enough stock.
I checked material & I found that MRP type is ND, there is no entry in the planning file for this material.MRP list & stock requirement list of this material is showing nothing. So there is no way that PR will be created automatically via MRP run for this material.
When I checked one PR for this material, Plant & storage location, creation indicator is showing as B Material Requirement planning.
Could you please help me that why creation indicator is showing as B>
I further checked these PRs are created long back when MRP type was V1. Later they changed it to ND.
How to delete MRP generated PR manually when PO has been created for these PR.
Regards
Shilpi
Edited by: sapmm1234 on Dec 14, 2011 6:10 PM

As you said; the PR was created long ago by MRP, when it was not ND.
If it was already converted into a PO, there's no need to delete it, right? If not, just delete it manually.
In the future, when you change MRP type from a valid type to ND, always remember to do 2 additional things, as the system will not do them automatically:
1- delete the MRP list
2- delete any planning elements if they exist, like planned orders and MRP generated PRs.

Reoder level planning (MRP)

Hi,
As result of <b>Reoder level planning (MRP)</b>, system is giving me one PR for one material. So if i take 1000 material under MRP then it will give me 1000 PR, which is very difficult to process.
Is there any way, so that system gives only one PR with multiple line item for 1000 material instead of seperate PR for each material.
Please help
Regards,
Sachin

HI Sachin,
WHile you run MRP it will consider each material Info record and price and dependecy , every material will have different requirement so it is not possible if you need collective PR from MRP
but it is possible with manual PR, You can create number of line item in one single PR
Hope it is clear
Thanks

Is it possible that we generate material requirement in MRP at company code level?

We want to generate material requirement in MRP at company code level, what is the possibility or any work around.
Thanx in Advance.

Hi Mirza
This is not possible on the standard system. The highest planning level on MRP is the plant.
It has been discussed on the following thread, where BAdI MD_CHANGE_MRP_DATA was proposed as a solution, however, the logic to be implemented on this BAdI is very complex:
MRP Run considering Stocks for Multiple Plants and Requirement maintained for Plant Cluster
If you want to know more about the BAdIs available on MRP check the following document:
BAdIs for MRP
Another alternative is to use flexible planning to plant at company code level, then disaggregate the planning to the plants and transfer the result to demand management and MRP.
See the following thread for details:

Need Resource planning tool in ECC 6.0

Hi
i need to findout Resource Planning Tool in ECC 6.0,Can anybody help me how to findout RPT tool in ECC6.0.
Thanks & regards
Vikram Gopal

Hello,
Resource Planning
Use
Resource planning is a planning aid. If you only know the quantities of consumed resources (see also: Resources) you can use resource planning to plan activity-dependent or activity-independent primary costs or revenues by quantity. You can carry out detailed planning of a cost element by subdividing the cost element on the basis of the resources. The system valuates the given resource consumption with a price, which you can store separately in the system.
You can also link resources to a material or to a base planning object. This means that a resource or a base planning object has been entered in the resource master record. For the valuation of resource consumption during planning, the system uses the price of the material, regardless of whether you have defined a price for the resource during pricing (see also: Pricing).

Datasource 2LIS_03_S194 (Material Requirement Planning)

Hello SDN:
I need to extract data from the datasource 2LIS_03_S194 (Material Requirement Planning) relevant to me. I know this datasource is LIS and to fill it, I need to run a program RMCBMRP2 to fill set up tables, and this doesnot support Delta update.
I have one doubt, that for future MRP data Loads will I have to execute this Program every time and do full loads..? OR can I schedule a job to do.? If so, how to schedule a job.?
Please share your experiences with me.
Thanks in advance,
Regards,
Kalyana Pidugu

Hi Kalyana- I am also using this same datasource and not sure when to run the program RMCBMRP2 in ECC and what parameters (regarding period/dates) to provide in SE38 while running it. If you have found more info on this can you share with me please?

Material Requirment planning

Hi Experts,
We are SAP ECC 6.0 ( Apparel and Foot wear solutions ) , we run MRP on 3 months basis , our lead time for raw materials is 90 days , now when i run the MRP for the month of may , june , july the requriemnts of july , august , september are getting generated we will be having different release dates in the purchase requsitions as per the requriement.
For example we have a Purchase requistion for which the release date is 01/06/2010 , ( In this requistion the material is FFK and the grids are Black, WHite , Red) . i would have ordered only the Black grid for this month and the remaining grids are open )
now when i run the MRP run for next month and my requirement is less as compared to the preivous run , then the system should delete that two Grids from that PR and create new PR as the new requirment .
Is it Possible to do so . What is the standard functionlaity of the system , how does it work ,??
Regards
Rakesh

Dear ,
Couple of question I would like to know :
1.What is the MRP type are you using because you can fix the Roll Forward Indicator at MRP type and also Roll Forward Period -SPRO-MRP-Planning -MRP Calcualtion -Planing Time fence and Roll forward period .HEre you can also set the Delete Firmed order .
The roll forward period defines a period for updating the master plan. In this period, the system deletes all firmed orders that lie before the roll forward period on the time axis.At the same time the system adjusts the master plan to a new situation, if necessary, that is, if new requirements have been created, new orders are created.
2.Any planning time fence ?
2.What is the time frame in Grids ? i means you want delete and recreate new planning considering grids ?? could please explain that .
R you running MRP with folloing set up ?
NETCH
Create PR -1
Schedule Line : 1
MRP List : 3
Planning Mode : Delete and Re-create Planning mode -3
Othewise you need to set Delivery Complete or Deletion flag for those grids of PR collectively and Run the MRP .
Try the above possibilites if you can or else set deletion flag or delivery complete indicator for those PR.
Regards
JH

SAP DRP (Distribution Resource Planning)

Dear All,
I have gone through the SAP DRP help. Can somebody explain with one example about DRP, where it is useful and how to process DRP in SAP PP. Any config settings to be done, How to set up distributuon network and How Deployement to be executed. Your help will be highly appreciable.
Thanks & Regards,
Ramagiri

Hi ,
There is a config under Prod--> DRP-->Basic setting-->Main assignment of node type-plant. here you can define Plant as B-Distribution center. There is no significance of this config.
Since you need plant to hold stock , Distribution center will be a plant object with node type defined in above config( Or you can implement MRP area , if you donot want to create more plants)
Either way ,
You have setup stock trasnfer between Plant(DC) & Plant using special procurement type(F-40) & system will generate Stock transfer PR which can be converted in Stock transfer PO
You can set up multiple key 41,42,43,44 for each plant(DC) pointing to differenet plant(Mfg)You can use this key in material master of Plant (DC) to define which plant will supply this material.
SAP MRP run is also deployment , it will plan Stock transfer PR based on demand entered on Plant(DC)
Hope it helps,
Jatin
