In mrp

what is the diffs b/w safety stock, reorder point, backflush

Hi Bakyaraj,
Safety stock: This is the buffer stock which defining in Material master , if  you are stock is falls below safety stock then system give mesg or error depends on the settings in SPRO , u can see this while converting planned order to production order.
Reorder point: This one of the MRP procedure like MRP, MPS and consumption based planning eg RO point.
This u can define in MM01 of MRP view .
If the  plant stcok and firmed receipt  falls   below RO pont then system calculte the shortage  quantity automatically with the help of Lot size procurment - generally it is replenishment up to maximum level and Fixed lot size.
For this u have to give RO point u have to give Safety stock ,Average consumption
Replenishment lead time if ur using this lot size , with this u also define  Past consumption values (historical data) or future requirements
Vendor/production delivery timelines
Service level to be achieved
Forecast error, that is, the deviation from the expected requirements it dependa wheather u r using manual RO point or Automatic RO point.
Backflush:This function is auomatic posting of goods without doing MB31 with 101and MB1B with 261.
This settings u can do in MM01 , work center and routing.
Apart from this there is one more setings in OPl8 i.e order type dependent parameter .
In REM process there is agin backflush terminology for posting order / production these are assebbly backflush BOTh GI and GR done.
Component backflush - only GI done
Activity backflush - only activity posted  no GI and GR
Hope u will clear , If so then reward and close this thred

  • 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,
    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

  • 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 are the criterias to consider while deciding when to run the mrp?

    Hello Friends,
    Actually i was just thinking,if any company wants to run the mrp for planning than how to decide,when to run the mrp(daily,weekly,monthly).
    One of the factor,while deciding this could be the raw material procurements,right?if they procure raw material once in a month than they should run the mrp once in a month.(even we can control this by keeping monthly lot size,if you run the mrp every week).
    What could be the other reasons?
    Thanks and Regards,
    Jitendra Chauhan

    Dear Jitendra,
    As said by our other forum friends it depends on the business requirement.
    In one of my project as the client were recieving monthly plan for their production MRP was carried out monthly.
    It can be based on the production plan or say sometimes the maximum lead time for producing a product.

  • Creation of SDEB's for MRP type = VB materials.

    Hi Gurus,
    When we run plant wise MRP, SDEB's are created instead of Purchase requisitions for all Manual re-order point materials. We understand that SDEB's are created when the stock of tha material is above tha Re-order point, and this SDEB's indicate tha MRP controller whether he can create manually Purchase requisitions or not.
    But, we are getting these SDEB's for the materials that have stock below the Re-order point as well. Which is not correct i think.?
    For your information, when we run material wise MRP there are no SDEB's at all.
    Please explain what might be the Root cause and the solution to over come this..
    Thanks for your understanding..
    Naveen.A

    Dear colleague,
    without checking the issue it is difficult to know if there is an error.
    Please check if the following information can explain the behaviour of your system:
    A)When you do MD01 or MDBT the creaton indicators defines in the
    customising are used . whereas when you run MD02 or MD03 the creation
    indicator on the individual screen is used.
    Single-item planning and total planning follow a different logic
    concernng the creation indicators.This is also described in the
    documentation for Master Planning/Materials Planning (Chapter 4, Section
    2) and in the Implementation Guide.
    Single-item planning:
            The entered creation indicators are generally valid.
    Total planning:
           The entered creation indicators are used as default values.
           For materials from an MRP group, the values from the MRP group
           apply (if available).
           The creation indicator for delivery schedules can additionally be
           specified per plant. This is used if nothing was specified via
           the MRP group.
           Thus, the priority is as follows:
          1.  MRP group
          2.  Plant
          3.  Initial screen
    B)In MD02 system can de multilevel (For components of a header Materia)
    or/and Multiplant (Stock Transfre ) planning. In such cases for all the
    materials involved the creation indicator used in the screen is used.
    C)The creation indicator makes sense only for materials having
    procurement type external procurement (F) in material master. For the
    materilas which are produced in house (Procurement type E) system will
    always create planned orders.
        And Materials having procurement type X(Both procurement types ) is
    treated as Inhouse produced material by planning . Thus for such
    materials system will always create a planned order. Now this planned
    order can be converted into a production orer or into a purchase
    order(via purchase Requisition).
        When you run MRP with "Create Purchase Requisition " in the opening
    period , then the syetm uses in the opening period defined via  the
    scheduling margin Key. In material master , MRP 2 View we maintain
    scheduling margin key. And in Transaction OPP1->Planning->Scheduling and
    Capacity Parameters ->Define floats we maintain the opening periods per
    plant. I am attaching details of Opening period :
       opening period: Opening period is the time which the MRP controller
    needs to analyse.Thus he has this buffer with him to rectify any issues
    before converting the planned order into purchase requisition.
    The opening period is only used in backward scheduling.
    Suppose There is a requirement for a material on date =RD1
    Let the Goods receipt processing  time  is= T1
    Let the planned delivery time =L1
    Let the purchasing Processing time = X1
    Let the opening period for this material is P1
    Time line  for external procurement:
            Planned Del   Pur proc         GR Process
              Time            Time          Time
    ___|__________|_________|___________|___
                  L1            X1         T1
       SD                                         RD1
    Now accoring to Basic scheduling:
       Receipt/Requirements Date(RD1)
       Release/Start Date(SD) = RD1-T1-L1-X1
    Now let me explain to you when the planned order an purchase
    Requisitions are created:
    Let us say the date on which you do MRP be MR1
    OD = Opening Date
    From above diagram :
                                     Opening Per
                                     In Sch Mar Key
    __________________|______________|
      XX                          OD                 SD
                                                  Release/Start Date
    If your MRP date(generally Today) is lying between XX and OD (and
    excludind OD)then
    MRP creates planned order and if it lies between (and indclind OD)
    OD and SD then we create purchase req.
    when your MRP date comes between the period OD and SD then you do not
    have time left to analyse and therefore instead of you in such cases
    forgetting and delaying system automatically creates purchase req.
          In general if , if your order start date or release date is after
    the opening period from today then MRP will create planned order.
    Oterwise it creates Purchase req.
    Check also if you have the note 1063969 applied in your system.
    I hope it solves the issue. Otheriwse I think you should open an OSS message with connection to your system,
    best regards,
    maria

  • MRP - Ponto de Ressuprimento (VB-HB)

    Senhores, devido á crise, preciso mudar a forma de executar o MRP, que até então é o tipo VB e o tamanho do lote HB (estoque máximo). Só que eu preciso comprar até atingir o ponto de ressuprimento (estoque mínimo) e não o estoque máximo. Há alguma forma disso ser feito? Não gostaria de perder o histórico do estoque máximo. Aceito sugestão para fazer o MRP e comprar pelo estoque mínimo.

  • MC.9 report is showing -ve value when MRP controller selected

    Hi Expert,
    I'm confuse about the -ve value in MC.9. If i run by using Plant as the selection parameter for month 02.2010, then sorted by valuatted stock value(ascending), it will not show me the -ve value for all materials. But if i run the report by using Plant and MRP controller as the selection parameters,then sorted by valuated stock value(ascending), it shows me the -ve value. why?
    Please explain.
    Thanks

    hi jurgen,
    i still not clear. I try to run the report for material A and mrp controller  001. I got the -ve value. But when i run the material without mrp controller, it shows 0. no -ve value. i check in MM03,changes history for the material. MRP controller has been changed few times but the latest is 160. What am i confusing is, what is the relation between MRP controller with the report? What is the function of the report actually? Isn't it suppose to give the same data either i put the MRP controller or not when running the report?
    Thanks
