My reply - just  make sure while you run MD51, scheduling should be "2"(basic date will be determined  for planned orders) and revert if required.

  • MRP issue for future delivery PO/STO date

    We have a sceanrio where the available material quantity in MRP list is considering future delivery date STO quantity.  The PO delivery date is 08.11.2008 and MRP run date is 07.11.2008.
    Step 1, material master details:
    Material = 16814, MRP Type = PD, Lot size = EX, Special Procurement = D0 (Stock Transfer), Consumption mode = 2 Backward\forward consumption, Fwd Consumption per = 0.
    Step 2, MRP list details , before PO creation:
    MRP list before having any purchase order = 191-
    i.e, Available qty on 07.11.2008 with a DepReq = 191-
    Step 3, Creating Purchase oder (In our case it is STO):
    We created one Stock Transport Order on 7th Nov 2008 giving Delivery date as 08 Nov 2008 which is in future. Our plant is receiving plant = y100.
    PO quantity = 2
    Step 4, Running MRP in MD02:
    Processing key       =   NETCH               Net Change in Total Horizon       
    Create purchase req.   = 1                   Purchase requisitions             
    Delivery schedules   =   3                   Schedule lines                    
    Create MRP list   =      1                   MRP list                          
    Planning mode     =      3                   Delete and recreate planning data                                                                   
    Scheduling         =     1                   Determination of Basic Dates for Pl
    Result = PR is getting created for Qty = 189, but our actual required  qty = 191 - meaning it is considering the future delivery date(8th Nov 2008) PO qty while creating PR and removing that qty while creating PR's on 7th Nov 2008.
    Here we are running the MRP on today (7th Nov 2008). STO delivery date is 8th Nov 2008
    Step 5, MRP List details, after STO creation:
    Now the PO is coming in MRP list and the available qty is 189-
    Earlier stock before purchase order is 191 - after creating purchase order (STO) for future delivery date available qty is coming as 189-
    DepReq is still 191- but the total available qty is changing to 189-
    We want PR to be created for DepReq of 191 and not 189.

    In step 2
    What is the stock?
    If it is PO then the qty cannot be in  minus 189
    step3
    Where are u running MRP? In receiving plant or sending plant and all the steps you are showing for which plant?
    It is confusing...
    What i can say is in general if it is MTS scenario, then system will always consideres stock + receipt - issues = 0 after running MRP.
    If it is MTO, then for each sales order/project segment stock + receipt - issues = 0...
    Hence apply your situation in the plant and see the data.

  • MRP issue after MRP run

    Hello Everyone,
    We have a issue in the MRP process. When we run MRP it creates PR for additional quantity then needed not considering the Purhcase Order that exisits already. Below example will explain you in detail.
    Product A Plant ABC
    Stock 4
    Product A safety stock = 8
    Purchase Order creatred = 3
    So when MRP run it should create another Purchase requistion for Quantity 1 (4-8+3 =1). But it is creating a Purhcase Requistion for Qty 4 which means it is not looking into the Purhcase Order Qty 3 that is coming in. There is no minimum lot size or any rounding rule.
    Please can you tell me if there is a settings/config where we allow/not allow the Purchase Order to be considered during MRP run. I think it should be a plant specific config as for our other plant I dont see this happening.
    Any help will be appreciated.
    Thanks

  • MRP for Project MD51

    Hi all,
    I have a problem that is showed below:
    Our general stock is 100 for material ABC (procurement type is F: external procurement).
    We have 3 project stock for 3 WBS element. They are
            - Project stock 1: 0
              OrdRes: 50
            - Project stock 2: 0
              OrdRes: 30
            - Project stock 3: 0
              OrdRes: 60
    Total requiment for 3 WBS element is 140.
    When I run MRP for PS by tcode MD51, the system generate 3 PR for material ABC particular for each of OrdRes.
    1. I think that the system will generate 3 transfer posting for each of OrdRes, doesn't is? That is the first system.
    2. The system will generate one PR (quantity 40) to cover 3 OrdRes based on current stock (quantity 100), doesn't is? That is the second question.
    3. Are there any distribution key to distribute auto from general stock to project stock? And when I run MRP by MD51, the system will generate PR with quantity exactly for each OrdRes, doesn't is?
    Thanks all

    Hi Mario
    I have checked by assign "2" in field individual/collect on tab MRP4. When I have assigned this material to activity in project and release. in MD04, I can't see Order Reservation be assigned in project stock. So, when I run MD51 for project, the system does not generate planned order for this material while I want run MRP for WBS element
    Besides, if field individual/collect on tab MRP4 not be assigned "2", the order reservation will be appear follow project stock in MD04. And when I run MD51, the system will not check stock in general stock.
    I wonder why SAP does not support for me to run MRP for each WBS element and generate planned order base on check general stock and project stock at the same time?
    Can you aupport me to solve this case
    Thanks and regards

  • MRP Issue

    Dear Experts,
    I have some confusion about MRP wizard.
    In MRP running wizard step 3 of 4 i checked Existing Inventory, Purchase Orders, Sales Orders and Production Orders.
    But in  the order recommendation report status is not considering the Open Purchase orders Qty., its only consider existing inventory for child items.
    Waiting for you kind reply.
    Thns & Regards ,
    Ravi Jha

    Hi Ravi.........
    If you ticked those check boxes then it means Recommendation report will come for qty minus Ordered Qty and minus Committed Qty if something existing is there in system.
    It wont add up such Qty......

  • MRP Issue: Planned orders Vs Pur Requisition

    HI All.
    I have a query on MRP.
    We run Total planning for a plant in a night batch job  The parameters for variant are as below
    Planning Run Type: NETCH
    Creation Indicator for Pur Req  2.
    Planning Mode 3 Delete & recreate order proposals
    Scheduling type Lead time scheduling
    For example MRP runs on 19th Jan & for a given material, a planned order is created as the lead time 10 day & the requirement date is 15 Feb.
    Now as normal proedure, when the opening date in the planned is reached, MRP should delete this planned order & create a Pur Requisition. But this is not happening even though we have used the planning mode 3 (delete & recreate order Proposals)
    There is no planning file entry for the material after the initial MRP run. Is this the reason that the target material is not picked up in the planning.
    Any suggestions on this.
    Regards
    Vineet

    Hi
    If Requirement is 15 Feb System Calculates and Gives the proposal for 05 Feb. As you may know there is one more Schedule Margin Key  and itu2019s a buffer time before and after Procurement prosal. May be its affecting your Openeing period. Please Check the Paramaters in Material Master 1. Schedule Margin Key,2. GR Processing time, Lead Time  and planning time Fence(During this Period System Doesnt Allow Automatic changes,,

    Goods Movement
    Maintain in OPK4 as ALL COMPONENTS-this is for automatic goods receipt and automatic goos issue.

    2.When i am converting planned order to production order at that time i am unable to get the default Order type its throwing an error enter order type .
    Create Production scheduling Profile(OPKP) in spro-Maintain in order type in make to order or make to stock enter respective order type and save.
    Assign this Production scheduling Profile in respective material master in work scheduling view.
    now it will works.

    any reply is highly appreciated!

    Hi,
    MRP is by default licensed along with e-business suite.
    You do not need explicit licensing for using MRP.
    For further queries, please contact your nearest sales office or your sales representative.
    Hope that answers your query!!

  • Production MRP Issue

    Hello,
    In our facility, we have production finish goods, raw materials stored at the warehouse and the other warehouse goods that we purchase. I am trying to run MRP for production finish good and their raw ingredients. However, whenever I try to run it, I always have some other warehouse items not used as ingredients that ae processed.
    How can I segregate my production MRP run?
    Thank you!!
    Chaka

    Hi Chaka,
    Another good option to include only selected materials in MRP run is to use MRP area.
    Try exploring option of 'MRP area for storage location'. System will consider only those materials which are in specific storage location (defined as MRP area). You can exclude the materials which you don't want to plan in MRP by assigning these materials to some other storage location.
    For more details on MRP area refer following link.

  • MRP Issue for subcontracting

    Hi Gurus
    When a requisition is used to build a Sub-Contracting Repair Purchase Order, then subsequently a delivery u2013 a new requisition is raised, usually once the delivery has been post goods issued this new requisitions is automatically canceled on SAP, but recently this is not the case the requisition is still active.
    Please suggest me what was the reason for this one.
    Thanks & Regards
    Sada

    Hi,
    I am not quite sure if I have understood the problem, but sometimes inconsistencies occur for dependent requirements for subcontracting purchase orders. Refer to SAP note 115899. Note explains types of such errors and  there exists a program to correct these inconsistencies.

  • MRP issue with statergy 10

    Dear Firends,
    Iam having problem in MRP, My statergy is MTS. i get for a fert material purchase document/sale order from different shops say arround 50nos. per day.
    Now my stock is ZERO, i have not put any PIR in MD61. if i run MRP it is considering all Purchase and sale orders and giving individual proposals. But according to statergy 10 it should not consider any thing other than PIR. can u tell me what might be wrong in this
    sree

    Dear Vijay,
    in Statergy group only 10 in maintained.
    It is considering purchase orders requirement. i e. purchase orders created by our customers, so we need to suooly it from our plant. All purchase order requirement is seen in MD04 as requirement. When i run MRP it is creating individual planned order for each customer purchase order.
    it is considering Purchase order requirements as PIR, My requirement is it should not consider.
    Suppose if it considers also it should not give individual planned order for each reqirement. it should give one per day. To test this i changed lot size in Mat master from EX to TB. still no change in proposals

  • MRP issue -reg

    Hi Friends,
    The quiery is like this
    MD01 is scheduled as a background job using MDBT transaction . Here  values are maintained for MRP control parameters which appear on MD01 initial screen like
    Processing key  
    Create purchase req
    Schedule lines  
    Create MRP list 
    Planning mode   
    Scheduling      
    Planning date   .
    Though here it is given that no schedule lines , MRP output is giving schedules for BOM components
    quiery is which control parameters are preferred while system is executing  MRP   ,
    1.The Plant parameters which are maintained  at plant level  
       thropugh OPPQ
    2. The Plant parameters which are maintained  at MRP Group
         level thropugh OPPR
    3. The MRP control parameters entered in  MD01 initial screen
    4. Master data maintained like planeed delivery time , etc... for
        material in material master
    another doubt is while running how the system considers the MRP control parameters pertaining to the BOM header parts and BOM components
    regards,
    Madhu Kiran

    Hi,
    For MD01, system will check MRP group parameters for particular material. MRP group creation indicator overwrite the initial screen of MD01 creation indicator.
    If MRP group not found system will use initial screen of creation indicator.
    For MD02, system will overwrite MRP group creation indicator. MD02 initial screen indicator has priority over MRp group.
    For your last question also system will work as above.
    Check the following taken from SAP Help.
    The creation indicator for purchase requisitions is only valid if the MRP group does not override it. The creation indicator for scheduling agreement schedule lines is only valid if the MRP group or the plant entry in Customizing does not override it (see Creation Indicators in the Initial Screen and the MRP Group ).
    In single-item planning the creation indicators in the initial screen overwrite the creation indicators in the MRP group (see Creation Indicators in the Initial Screen and the MRP Group).
    Regards,
    Dharma

  • MRP Issue - Requisitions Completed in SRM not Cancelled in R/3

    Hi,
       We are running SRM 4.0 in an Extended Classic with R/3 5.0. We are having some MRP requesitions created from R/3 that came into SRM and the reviewer wanted to cancel the req's in SRM for some reason. So the req's are flaged as complete. But the completed req's are not getting cancelled in R/3. It used to work before but we recently did an SP12 upgrade to our SRM 4.0.
    Can any body through some light?
