PR differentiation in MRP

Hi,
A Part is purchased from a Supplier simultaneously on free of cost basis as well as on chargeable basis. I need to differentiate the requirements in the Supply Schedule to the Supplier. What config steps are required in MM / MRP? How does MRP differentiate these 2 types of purchasing?
Raj

Hi,
Thanks for your reply. But we do not want any manual intervention by way of assigning appropriate Valuation Type as the count of POs are very high.
Moreover, I need to raise a PR - one as Free of Cost goods and the other one with a Price. Is there anyway to achieve this by document types?

Differentiation between PRs' Coming from MRP Run & Reservations

Hi,
How can we differntiate that a PR is coming from MRP Run (If quantity falles below ROP) and Reservation (If Max is 2 and reserved is 4)
Appreciate your responses

Talha

Hi,
I didnt get the second part of the question...could you please elaborate.
The PR creation indicator will be in PR - item level - contact person tab as shown below.

Listing PR created through MRP alone

Is their any way of differentiating the PR created through MRP and through ME51.
My need is to list PR created through MRP alone.
- David Boon

Hello David,
As Anand said, you can use the tcode ME5A to get this report, but for your requirement you need to select criteria from the dynamic selection list.
- Go to ME5A
- On the initial screen you will find one colur icon (Dynamic Selection), click on that
- you will get window where you have to double click on "Creation Indicator" which will pull one field on your selection screen.
- In this screen you can give your criteria for PR creation selection i.e. B for MRP, D for manual creation etc
- Save the variant for future use.
Hope this will help

MRP information

Hi,
I am working on ECC 5.0 and got stuck with one of the client requirement.
My client want to extract the information about the PO that are created because of some demand.MRP(dependent or independent requirement).
Business process is that MRP run-> PR cretaed-> PO created wrt contract . Contract field is mandatory, but not the PR field.
Thus when user create independent PO with reference to contract, even though no requirement has been generated, our MRP purpose failed.
Please let me know ,is that possible to extract from some table , whether PO has been created because of some demand.
regards
Sandeep Kumar

Hi Sandeep,
If the PIR or dependent requirements trigger a PR during an MRP run and if there is a Source list maintained with the Contract mentioned in it then the PR created will also have the reference of the Contract. When these MRP generated PRs are converted / adopted into POs then these PO lines will have both the PR as well as the Contract in it.
Now you can find based on the relevant PR for the PO whether it is MRP generated or Manually created.
If you want to Optimize the Process then you can use ME59 to automatically convert only the MRP generated PRs to POs. BY doing so you can have that as a differentiating factor for the POs created based on demand.

Differential excise duty CIN

Hi
This relates to CIN.
A non MRP Excise Invoice((J1II) was raised for an MRP material without maintaining the ZMRP/ZABT price condition. This resulted in passing a lower excise duty amount. The customer is asking for a debit note and a corresponding supplementary excise invoice. We too want to do the same as we need to pay back the balance excise duty to the govt.
I am sure this is a common problem faced by users.
Can you pl help on this.
Regards
Ganesan

Hi Rajan
Thanks for your reply. Atleast you hv given hopes that this can be handled. I might have to go for option 1 as i assume we cannot create an excise invoice via option 2 as the customer needs cenvat credit. Am i right!!!!
But I need some more help. In my case the basic Sale price(SP) has been charged correctly. Error happened exactly in relation to Excise duty(picked up the SP instead of MRP).
Is it possible to raise a debit memo exclusively for the differential (excise dutycessVat)? Not sure if SD would pose certain limitations in creating such a Debit memo which does not contains the 'differential basic price'. And in such a case will you option of J1IIN work. Can you please share your ideas.

What is MRP and why it is used?

hi
this question was asked in an interview can some one explain in detail for me
What is MRP and why it is used? If there are 2 Lakhs of items is it feasiable to run MRP since running of MRP for 2 lakhs of item is time consuming, if yes then how it is been done?
thanx

Dear Bashir,
1.MRP is material requirements planning which plans the required quantity of depedent material's along with the required date.
2.MRP procedure is sub divided into a normal MRP,Master Production Scheduling and Consumption Based Planning.
3.Cosnumtion BAsed planning is further sub-divided into Time Phased Planning,Reorder Point Planning and Forecast based
Planning.Reorder point planning can be automatic or Manual.
4.MRP type is differentiated using the MRP type value assigned in the MRP1 view of the material master.
5.Some of the MRP types are PD - MRP,M0,M1,M2,M3 - MAster Production Scheduling related,VB - Manual reorder point
planning,VM-Automatic reorder point planning.
6.It is possible to take the MRP for the whole plant/for a specific MRP area using the batch MRP job.
7.MDBT is the T Code for scheduling the MRP job or it can be scheduled for the program RMMRP000 using the T Code SM36
and the results can be checked using SM37.

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

Order of delivery schedule line counter at schedule agreements from MRP run

Currently we are using schedule agreements for our long term external suppliers, but we are facing a problem with the order of new delivery schedule lines created during MRP run.
Because of master data settings like, lot size, rounding value, plan delivery time and planning time fence to set as firm new requirements, multiple schedule lines are created with no order for schedule line counter.
Does anyone is aware of a BADI, user exit or customizing control to have this schedule line counter in order?
Thank you

MRP - Auto creation of del schedule lines based on planned delivery time

Hi,
We have activated MRP (type PD) where Purchase requiesition is auto created by system for requirement quantity. We require to optimize delivery schedule in such a way that entire PR quantity is broken into various delivery schedule based on planned delivery time and requirement. Scenario can be further explained with following example.
Material Requirement for a month is say 1,25,000 units
Closing Stock say 25,000 units
PR Generated by system for 1,00,000 units. The entire quantity is schdulled with only one delivery schedule line as per planned delivery time.
The requirement is to generate multiple delivery schedule lines automatically in Purchase requisition based on planned delivery time so that Purchase orders can be placed with system generated delivery schedule lines.
How can it be achieved ?
Regards,
Nirav Kinkhabwala

Nirav,
This subject has been discussed repeatedly in this and other forums. I must assume that you overlooked the rules of engagement, which state that you should first search the forums and other public sites, before posting questions here.
Standard SAP MRP cannot be made to generate multiple items in a Purchase requisition. The functionality you seek is usually achieved when converting purchase reqs to Purchase orders, where many single purchase reqs can be adopted into a single Purchase order.
You also might want to investigate use of Vendor Scheduling agreements.

MRP To Generate SCHEDULE LINES for Scheduling Agreement

Hi
I have followed the below steps but still the Schedule lines is not generated for scheduling agreement.
1Maintain MRP views 1,2,3,4 for the material in material mste.(MM01)
2. Maintain Purchase Info Record for the vendor plant & material combination.(ME11)
3. Create Scheduling agreement using ME31L
4. Maintain source list for the material & the scheduling agreement # and Line item set the MRP relevant indicator 2 (Necessary ?) ME01
During Run MRP for the material.the below details entered///
Processing key NETCH Net Change in Total Horizon
Create purchase req. 1 Purchase requisitions in opening period
Schedule lines 3 Schedule lines
Create MRP list 1 MRP list
Planning mode 1 Determination of Basic Dates for Planned
Run MDBT or MD02 but still doesn't create the schedule lines......Anything else missing.
MRP1:
MRP Procedure: PD
MRP Group: 0000 (External Procurement only)
Lot Size: EX (Lot For Lot)
MRP2:
Procurement Type: F
Sched Margin Key: 000
MRP3:
Avilablity chec: 02 (Individual requirement)
MRP: 4
Nil

Raj,
Source List a Mandatory for Scheduling Agreement, if you want to create automatic Scheduling line.
Plz use (2) in MRP RELEVENT tab in ME01 (Source List).
rest of the thing is ok, make sure a material master(MRP 2 VIEW) in that view you have to give a planed delivery days. it is must.
HOPE IT WILL WORK

Schedule lines are not getting generated through MRP

Hello Experts,
While running MRP, we observed that the system is creating PR instead of schedule lines, although all the necessary prerequistes to generate schedule lines through MRP are maintained. For e.g.
1. MRP Schedule line relevant indicator '2' is maintained in the Source List.
2. Sch. Agreement dates and Source List validity dates are same.etc...
Further after some analysis, we observed that if we change the source list validity from date to some back date then system is creating correct schedule lines.
Example: Material M1; Planned delivery time 7 days; GR processing time 5 days; MRP Type PD; Lot Size WB;
SA validity dates - 07.09.2011 to 31.12.2011
Source List validity dates - 07.09.2011 to 31.12.2011
If MRP run on 12.09.2011 and source list dates are retain same as mentioned above, system creates the PR.
If MRP run on 12.09.2011 and source list dates changes to 05.09.2011 to 31.12.2011, system creates the schedule lines.
Could you please let us know, why the system behave like this?

Dear,
Welcome to SDN,
In transaction OMDT you have to enable the indicator create schedule lines
In MD02 MRP control Prameter here select the Delivery schedules -3- Schedule line. Processing Key as NETCH and Planning Mode - 3 delted and recreated.
Maintain source list ME01, in that put MRP indicator as '2' i.e. schedule lines via MRP.Put your agreement no in that.
If u run MRP properly u will get schedule lines automatically in ME38.
Make the schedule agreement, make it source relevent in the source list make is FIX and MRP indicator as 3.

MRP Type P1 and late firm schedule lines

Hello All,
     We are using MRP Type P1 which firms our schedule agreement schedule lines within the planning time fence (as desired). However, sometimes the supplier is late on delivery and the firm schedule line goes into the past.
     Is it possible to have MRP move the firm schedule line delivery date to today instead of going into the past?
     Thank you,
     Jerry

Hi ,
Bring process forward (reschedule in)
Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement. Then the system displays a rescheduling date as well as the exception message Bring process forward for this receipt. The net requirements calculation then uses this receipt and the system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement. Several firmed receipts can be used to cover one requirement.
It does not take in to account the GR processing time and it is purely based on the stock requirement date , parameters in Procurement and Scheduling in the Material Master
So it will consume the requirement backward scheduling and bring the Process forward.
Kumar which strategy are you using ? scheduling agreement is of weekly , daily or monthly bucket ?
How many days SA bring to Production and How many days SA for forecast you are doing ?
Are you using any Program to convert these SA in to PIR and upload ( using any program ) .

*MRP unable to create Delivery Schedule Lines in MM Scheduling Agreement*

Hi Experts,
I need your help...
The issue is, in-spit of maintaining Source List with an u201CScheduling Agreement with item No.u201D & u201CSource List Usage in MRPu201D as 2 (Record relevant to MRP. Sched. lines generated automatically), MRP run does not generate Schedule Lines, instead PRs are created.
Please help me to understand such behavior and fix the issue as the requirement is to generate Schedule Lines only.
Thanks,
Pratap

Hello
Please check
1) Source List maintained properly in terms of Material # ; plant # ; proper POrg ; Schd Agr # and line item# ; proper validity date & MRP relevant indicator
2) Please also check Quata arrangement if you are using. whether % is maintained correctly against the vendor
3) MD03 , Delivery schedules- should be 3
4) check your planning horizon whether it is NETCH or not
5) check material master -MRP2 view, Procurement type is F- external procurement, schedule margin key if you are using
if everything above is set, then I feel it should work
Also please verify-
lot size, safety stock and the corresponding prod volume for MRP input v/s the stock available in MMBE
example.
MD04, we can see the open del lines.
if SS = 50 , prod volume is 150
1) if MMBE shows 200 then it wont generate any schedule.
2) if MMBE is 180 and your lotsize is 40, then after MD03, you will have a schedule line of 40 (provided if everything is set properly)
Please ensure there are NO open delivery lines . if you find such in MD04, then please close open delivery lines
in calculation of MRP, system considers such open delivery lines are going to receive and no additional schedule line generated even after MRP run
thanks

MRP is not working for one material

Hello,
I've run MRP without problems, but now I have a problem with one material. It is strange because if I copy that material with MM01, create the BOM and the run the MRP, everything works fine with the new material, but not with the old one.
Any idea why it could be not working, while the copy works perfectly?

hi
First of all check have u maintained MRP parameters correctly
( MRP type etc.)
Though u have created BOM but if parent material has no requirement then it will not create any requirement for ur created material so check whether parent material is applicable for MRP or Not
Vishal...
