MRP 2 of Material Master

Dear All,
Please explain me the following things with example for MRP 2 screen of material master (mm01)
Safety stock
Minimum safety stock
Dynamic Stock
Servive level (%)
Coverage profile
Regards,
Phalgun Patel

Dear
1) Safety stock : here you have to enter the qty .manually as per business requirement .After the MRP run ,you will  find the seperate MRP element SafeSt in MD04 and seperate planned order /purchase re. will be created for that.
2) Coverage profile   :this is required while calculating  Dynamic safety stock ( this stock is target qty in MD04 period total view ) :.The concept is that safety stock changes as per the requirement qty and period .It basically depends on average daily requirement .This you have to study as per the following link

    Hi,
    MRP is mainly configured for a material so that tere would not be any need for manual checking of the stock so as to create a PR. 
    The parameters which you have specified for a particular material like reorder point and lot size will help in planning for a particular material.
    If you need only Qty of two (Less) then  there s no need of configuring a MRP for that material
    And lot size is also decided basing on certain other factors like
    1) Lead time
    2) Transportation costs involved in procuring the material etc
    So ifyou want to generate PR for a qty of 100 then you need ot change the lot size
    I hope this gives you clarity
    Thanks & Regards

    Hi Loic,
    i have the same issue right now:
    System error: Inconsistency between Credit/debit indicator and amounts
    Message no. F5693
    Diagnosis
    When the FI/CO interface data was projected into the FI document, not all the amounts are positive. This is due to an inconsistency between the credit/debit indicator and the amount information in the FI/CO interface.
    System Response
    Negative amounts cannot be processed by the financial accounting application.
    Procedure
    This is a system error. Contact the SAP Hotline service.
    thing is that last friday this was working good, i have post several GR last friday and there was no issue then.. how did you solved this?
    thanks in advance

  • LSMW no create MRP flaps in Material Master

    Hello, I created a LSMW for Material Master. The material is created but the tabs are displayed MRP or Accounting. You do not know what else to try. Help please.
    Arturito.

    Hi,
    Have you set the parameters XEID1, XEIB1 to 'X' to enter the values.
    For the MRP view, SAP would require plant, storage location, MRP area etc.
    For Accounting view, SAP would require valuation type,
    Check if you have provided in your LSMW.
    Hope it helps,

  • MRP view in material master creation

    Hi Guys,
    Can anyone tell me how to change the settings for field dependency. My requirement is to use only the filed for "reorder point" in MRP view and do not enter any other data like MRP type or lot sizing etc.
    I have tried changing the setting for field selection group for MRP type etc but whenever i enter the value in Reorder point field it asks me for MRP type and does not allow me proceed...
    Thank you for your help.
    Regards,
    Siddharth

    Hi
    You cannot change that dependency as it is done through program code and not thru config.
    If you want reorder point only as an info field and not for actual Reorder point planning, I suggest you to explore any other unused information field in the masterial master.
    You can also use classification

  • MRP TYPE for  Periodic planning in the material master.

    Dear gurus,
    i need planned the materials in the periodic modality, are there the type MRP in the material master for create the planned file ( table MDVM) one once a month or in the specific period chose ?
    Example :
    I need that the material master don't create a file planned ( MD20- TABLE MDVM) for a change of the requirement situation new , but i would like that the flag in the table ( MDVM) or file of the planning MRP created when the today date is in the period specific.
    31.3.2011  (or period 1.4.2011- 10-4-2011)Date for the create a file MRP and after when run MRP planned the material, for others scenary the system must not planned the material.
    Are there the MRP type for my problem? Or the customizing setting?
    Thanks a lot
    Dani

    Dani,
    Not sure if MRP type or customizing can help here. And even if we are able to achieve this requirement it will be applicable at plant level.
    However, try exploring option of periodic lot size (weekly, monthly, etc). This will work according to period you've set and should give you the results you are looking for.

    Thanks for your inputs.

    Hope this can help you.

    Hi,
    The safety time / actual range of coverage ensures that the planned warehouse stock covers the requirements of a defined number of days. It therefore serves as a time float and thus works alongside the safety stock, which acts as quantity float.
    The system simulates bringing the requirements forward by the specified number of days and the planning for the receipts, created for these requirements in the planning run, is also brought forward by this number of days.
    Prerequisites
    ·   You have set the Safety Time indicator in the material master record (MRP 2 View) to define whether the safety time is only to apply to independent requirements or to all requirements.
    ·    In the material master record (MRP 2 View), in the Safety Time/Actual Range of Coverage field, you have entered the number of workdays by which the requirements are to be brought forward.
    ·    If, in addition to this actual range of coverage, you also want to define a different number of workdays in certain periods or a safety time less than one day then, in Customizing for MRP in the activity Define Period Profile for Safety Time/Actual Range of Coverage you can define a period profile and assign it to the material in the material master record.

  • Material Master change with MRP profile

    Has anyone tried to change material master MRP view by assigning new MRP profile?
    I do not understand why the field value is not updating if the MRP profile field is defined as default but if it is define as fixed value, it is updating in MM02-assign new MRP profile.
    thanks

    Thanks Vijay,
    I've tried to change material master MRP1 view with MM02-Edit-MRP Profile.  If I assign a new profile where values are set to fixed value, it is updating the fields and only another MRP profile update will allow change to that field.
    It is not updating the fields if you assign a new MRP profile where values in the MRP profile are set to default. I'm thinking it should still update the field value and at the same that field can still be change in manual MM02 transaction.

  • Special Proc KEy 30 in Material master in MRP 2

    respective guru's
    Pls explaing about the special proc key 30 (Sub contract)in material master of MRP2  and how to use  for external processing .

    Hi,
    In fyou want to get a material from a sub-contractor you will have to use spl proc key as 30.
    Suppose you watn to receive a HALB matl from contractor use key 30.
    When you run mrp, a planned order will be created.
    Convert this in to pur order.
    use me2o or mb1b & send the raw material to the contractor thro 541 mvnt.
    Then use migo 101 mvmnt & receive HALB.
    You have to use 30 only if you need to get the full material from the contractor.
    Suppose you have 3 operation for the halb & you want the contractor to do only the 20th operation then you go for ext processing. For this give control key pp02 in the opreation 20 in the routing.

  • Changes in Material Master leading to issues in MRP

    Hi,
    For a particular material a user changed a lot of material master data (MRP1 and MRP2 view) within a couple of hours.
    As a result MRP is not working as we would expect:
    - some orders have no quantity in the "Available quantity" column in MD04 and as a result do not trigger any PO (Received/Required quantity = -1, but Av qty = blank)
    - whenever a shipment is foreseen it is consumed/reserved by/for the order which requested delivery date is closest after that shipment date
    These are the changes made to the master data in November 2009:
    Planning Strategy Group: from Make-To-Stock Production to No Planning to Strategy Group for Spares & Consumables to No Planning to Strategy Group for Spares & Consumables
    MRP Group: from Client Specific MRP Group for Period Mgmt to General to External Procurement to Client Specific MRP Group for Period Mgmt to General to Client Specific MRP Group for Period Mgmt
    Availabilty Check: from Indiv. Req. to Indiv. Req w/o PO. to Indiv. Req.
    Unplanned Consumption in period: from blank to 11.2009
    Fwd Consumption Period: from 0 to 999 to 0
    Consumption Mode: from blank to Forward Consumption Only to blank
    Unchanged MRP material master data:
    Bwd Consumption Period: 0
    MRP type: MRP
    Planning Time Fence: 1
    Lot size: WB (weekly lot size)
    Procurement type: External Procurement
    Backflush: always backflush
    What should we do to have MRP work correctly again for this material?
    Changes to material master MRP? Delete all schedule lines and start from scratch in SOs?
    All help is much appreciated!

  • MRP view maintenance for Material Master

    What is the basic entry for R3 material master, if, I want EBP below condition works:
    Stock in R/3 sufficient: Shopping Carts creates MatReservation.
    Stock in R/3 not sufficient: Shopping Cart still creates MatReservation, and when run MRP (in R/3), it gives Purchase Requisition, with the exact shortage qty.
    Info: We have set customizing in EBP so that every follow-on document for Shopping Cart will be Reservation.
    -Mimi-

    In R/3  , the material should have MRP view and all planning related settings ...
    wr u want to go for consumption based planning or deterministic planning .
    Based on the planning procedure setting in MRP views of the R/3 sytem , PRs will get generated.
    This is what u are looking for .. otherwise post your feedback...
