Regarding MRP and WIP scheduling differences

One doubt is whether variable leadtime is used by both MRP as well as WIP scheduler. I have a feeling that it is being used by only MRP. The backward scheduling done by WIP scheduler always gives 3 times the days given by MRP . So if due date is say 3-jun-2002 for a particular item with quantity 100. MRP gives a start date of 27-May-2002 whereas WIP Scheduler gives a start date of 15-May-2002.I know that WIP is considering 8 hours as working time as defined in our workday calender but MRP is taking 24 hours as working time.Why is this so?

I had been a little out of touch here but the difference is in the type of scheduling, WIP uses what is known as Detailed scheduling algorithm and hence the difference. Will get back to you after clearing the cob webs created by recent randezvous with COM/MTS. Hope this helps

  • MM02 changing planning strategy, MRP, and customer schedule aggrement

    hello,
    everybody.
    Someone has told me that if I change in MM02, the strategy group for a material, I have to create another schedule agreemennt and delete ( invalidate ) the current. If not, MRP won't take care of the current schedule agreement and the customer demands.
    Is there a way to modify the schedule agreement instead of re-create it.
    Thanks a lot.

    if the req type is decided by stg group(check in procurement tab) and in case if it is not changing...then you can continue using the same or else you may have to create a new one.

  • Difference mpr controller and production scheduling profile (exact)

    hi gurus
    wht is difference between mrp contoller and production scheduling profile. and which will come first at the time of planning.
    thanks in adavance
    avinash.pegarlawar

    Hi,
    MRP controller
    MRP Controller is the person responsible for a group of materials in MRP in a plant or company.
    Material that takes part in material requirements planning must be assigned to an MRP controller.
    Production scheduler
    Scheduler responsible for a material in production activity control.
    Example
    The production scheduler determines how capacity requirements are calculated for a material during a scheduling run.
    MRP Controller comes into Planning first which you need to assign in MRP-1 View in material master while production scheduler you need to assign iin Work Scheduling View in Material Master.
    Hope this helps clearing your doutb.

  • MRP Area and SA Schedule Lines

    Hello All,
        We are looking at using MRP Areas and noticed it can not be turned off once on (ECC 5.0).  Given that, is the following true with reference to schedule agreements:
    - Will seperate schedule lines be created for each MRP Area (same material)?
    - Does the receiving storage location come from the material master or the MRP Area (Does it matter if it is a type 01 or type 02 MRP Area)?
    - Is it possible to define differen't receiving slocs in a schedule line for a Plant MRP Area?
    Thank you,
    Jerry

    Thank you Charlie,
        The link is helpful however it doesn't come straight out and answer the questions - meaning there is a bit of ambiguity there.
    It would be appreciated if you or anybody that is using MRP areas with schedule agreements is doing the above.

  • What is the difference between scheduling agreement and delivery schedule

    Hi
    1. Can anyone explain me the difference between scheduling agreement output
        and scheduling agreement delivey schedule
        Will the both look same in T.code SP02 when seeing the output for a document.
        Can anyone send me T.codes for above ones in purchasing.
    2. when seeing the Detailed statement for rebate agreement,there is item number.
        In which table can we see the item number for rebate agreement

    Hi,
    If you have to deal with more complex situations, you can define a delivery cycle in the material master record in addition to the planning cycle. In so doing, you determine the days on whichthe vendor delivers his goods. The delivery cycle is entered in the material master record as a planning calendar in the Planning calendar field.
    You enter a delivery cycle if the delivery date (or the goods receipt date) depends on the day on which you order the goods. For example, you carry out the planning run and place your orders on Mondays and Tuesdays. If you place the order on Monday, the delivery is made on Wednesday, if you wait until Tuesday to place the order, the delivery is not made until Friday
    Where as Planning calander is Three character number (numeric or using letters) that specifically identifies a PPS-planning calendar. The difference between Planning calender and delivery cycle is If you have selected the MRP type "MRP" and have set a period lot-sizing procedure according to planning calendar, you enter here which planning calendar is to be used.
    If you selected the "time-phased planning" MRP type, the planning calendar that you specify here defines the delivery cycle. This specifies the days on which the vendor delivers the material. You can enter the planning cycle in addition to the delivery cycle

  • Difference between Scheduling lines and Delivery schedule

    Hi SD Experts
    can u say me the clear difference between Scheduling lines and Delivery schedule.
    where we will maintain deliver schedule. whether delivery schedule is automatically created along scheduling agreements..
    with regards
    James

    Hi James,
    Schedule Lines: Has basically information realted to delivery scheduling in Sales Order level.
    Delivery Scheduling: Is a process using which system will determine what are the different activities which need to be performed and time taken for each activitiy only after which the material can be delivered to the customer.
    Delievry scheduling will be started only from the material availability date i.e., system will first determine the material avail date and then do scheduling. By default Standard SAP system does Backward Scheduling in case material availability falls beyond the required delivery date system will do forward schedluing
    Delivery Scheduling consists of the following Basic activities:
    We give deatils while creating order:
    Order Creation Date
    Required Delivery Date
    Order date - Material availability date - Transportation Planning Date - Loading date - Goods Issue Date - Required Delivery Date
    Time Between GI Date and required Delivery Date is called Transit Time
    Time Between LoadingDate and GI Date is called Loading time
    Time Between Material Availability Date and Loading Date consists of 2 components - Pick / PackTime and Transportation Planning Time
    System has to calculate all this before it determines the confirmed delivery date.
    Give your mail Id I have some Presentation I will send you across.

  • Difference between finite and infinite scheduling

    Dear Frndz,
    Pls tell me how the system will behave if I don't select the finite scheduling option for the work center.
    Thanks and Regards,
    Srini

    Finite Scheduling
    Scheduling type within capacity planning that takes account of the capacity loads which already exist.  Finite scheduling calculates the start and finish dates for operations in the order.  It is a detailed scheduling strategy with which you schedule orders and operations, taking into account the existing resource load. A resource overload cannot occur.
    Infinite Scheduling 
    A detailed scheduling strategy with which you schedule orders and operations, without taking into account the existing resource load. It is therefore possible for resource overloads to occur. 
    R/3 does planning without consideration for capacity situations. So if MRP says you need 500 parts on 3/1/04, it schedules them all to be built at the same time, even though you can only do 100 at a time. Assume you have a fixed lot size of 100, you'll get 5 planned orders for 100 to start on the same day. This is "Infinite Planning". APO would recognize that constraint, and instead schedule out the 5 orders over time. The important part of that is that it also will schedule out the deliveries of the components for 5 different days. This is "Finite Planning". 
    Now, assume old fashion MRP. It schedules all 5 orders for the same day, and the buyers go out an get all of the components for the same day. Then the planner realizes he can't do all 5, and manually changes the schedule, and manually spreads out the 5 orders. The buyers will recieve rescheduling notifications, but not until the scheduler does the manual rescheduling.
    You could call this "Infinite Scheduling", but that only means the same thing as Infinite Planning. 
    But, SAP has "Capacity Leveling". What that means is you run another program after MRP (CM27 and CM28), which can be run in batch mode overnight. (There is a ton of configuration and thinking that will be required to do this!). The capacity leveling program will recognize the constrant at the work center level, and fill up the first day, then re-schedule the next
    order to the next available capacity, then the next order searches for available capacity, and so on. This is called "Finite Scheduling". The problem with this is the opposite of Infinite Planning, which is it doesn't take Material availablity into consideration! The system will re-schedule a production order without thinking about whether the materials will be available
    or not. 
    Finite Planning does Finite Scheduling at the same time. If there is no capacity available on the desired date, the system looks for when capacity IS available. Then it stops to see if Materials will also be available (usually based on the lead-time for those components). If there is a material problem, then the system figures out when the materials WILL be available, and then 
    checks to see if capacity is available on THAT day, and if so, it blocks off capacity, and allocates the materials for that day
    Hope clear to you, other wise pls come back

  • MRP Behaviour with and without Scheduled SO

    Hi,
    How MRP would behave when there are Scheduled and non scheduled SO's with in the system?would MRP conisder non sched SO?
    If invemtory is reserverd fof non scheduled Sales Oders,how Mrp would behahve,.would it consider the reverve items?

    MRP only considers scheduled SO's. Any other is ignored.
    when you schedule the SO the visible_demand_flag field is set to Y in oe_order_lines_all. Only then does MRP sees the SO.

  • MRP Areas and Delivery schedules

    We have managed to succesfully configure MRP areas, however we still have problems of transferring the MRP results to Scheduling Agreement. We can only set source list at plant level. Now same plant has different MRP areas. Please help.

    Hi TAJUDDIN,
    Let me rephrase my quiry. We have a customer that sends requirements to us, which we then send through to MRP, which gives us the nett requirements, which are then sent to the supplier.
    We have been running this at plant level with no problem as the supplier was seeing all the requirements (from our customers/ subsidaries) consolidated. But now this requirements must be passed to the supplier per individual customer or subsidaries. For implementing this we created a new plant with storage Locations representing each subsidary, each subsidary has to be planned separately and handed to the supplier as individual requirements.
    Hence we looked at MRP areas for this, the other option was to create each subsidary as a SAP plant but this is not neat. Our problem is that we are able to plan with MRP areas but we are unable to pass the MRP results to the agreement that we have with the supplier.
    JUst though to give more infor of the full scenario might help, but in short you've been very helpful. I've learnt quite a lot.
    I hope you'll still be patient with me while I try and understand as well as address the current issue we have.
    Thanks.

  • Difference between Order Header BSD and operation schedule SSD

    Hi,
    One of your Client is operating on SAP 4.7
    There are some cases where Order Header Basic Start Date and operation Schedule Date are no same.
    example:
    Present Order Basic Start Date 24.06.2011
    Present Order Basic Finish Date 01.07.2011
    Forward Schedled order.
    Operation 1
    Operation 2
    Work Center has sufficient capacity and is available to perform work 24hrs.
    Using planning board CM10 user dispatches operation 1 to 30.06.2011 and operation 2 to 01.07.2011.
    The problem is order basic start date is remaining same i.e. 24.06.2011 and not chaning to 30.06.2011.
    Can any one please help in this issue.

    yes for all order types and also i have observed that most of work order has basic start date as 24.06.2011 when all the operations of orders are scheduled in future dates (date other than 24.06.2011).
    The first time scheduling of work order operation is done on 24.06.2011 (CM10) and then after re-scheduling (through IW38) of operation changed the schedule start date but work ordre basic start date remained same i.e 24.06.2011.
    Dispite of first time scheduling and then re-scheduling basic start date remained 24.06.2011.
    Note: Same profile was selected in both CM10 and IW38 while accessing planning board.

  • Questions Regarding MRP

    I had a couple of questions regarding MRP. Will be glad if you could answer these:
    Is it possible to remove the 'in house production time' & 'planned delivery time' from MRP?If it is possible, what will be the impact of removing the above?
    Can we change the start/end date of the factory calendar, with or without removing the above?
    Please answer the above.
    Thank you very much.
    Regards

    If we keep inhouse production time and planned delivery time as zero, will this have any other impact?
    Secondly, is it possible that we can manually change the start and end dates which are suggested electronically by SAP?
    As I said earlier if you keep in house production time as zero system still would allow to create a material master record and based on this MRP calculates the dates required for any planned order in basic scheduling.
    If you keep this as zero you order basic start and end  basic date would be on same day.
    It is recommended to maintain the no days required for in house produced material in MRP2 or in WS view or you need to enter the setup, tear down, processing, and inter operation times so that based on these values, the system determines the in-house production time on the basis of lot size.
    Same way for Planned Delivery Time, only the difference in both of these fields are In house Production time considers the FC where as Planned delivery time considers the calendar days.
    For your 2nd Question if you change the system proposed dates in any planned order based on the scheduling type start and end dates would be changes accordingly.

  • MRP and MPS

    Hi,
    what is the main difference between MRP and MPS ?
    Regards

    Hi,
    The task of material requirements planning is to guarantee material availability. The system calculates which materials must be procured or produced at what time and in what amounts so as to provide the quantities required.
    Using MPS you can carefully plan important parts or bottleneck parts in a separate planning run at the highest BOM level before the planning results have an effect on all of the production levels.
    Lead time scheduling and the calculation of capacity requirements in MRP and MPS provide the basis for the creation of a master plan that corresponds to capacity planning. This way the MRP controller obtains information about possible bottlenecks and overloads. Before the master plan becomes effective and the planning results affect subordinate BOM levels, the MRP controller can make changes that affect capacity for chosen materials.
    Scheduling:
    Before capacity planning can take place you must create capacity requirements within lead time scheduling, that is, determine the production dates. The system only generates capacity requirements if it executes lead time scheduling using the times specified in the routing.
    Scheduling in MRP and MPS determines the basic dates and the production dates for the planned order. The basic dates define the earliest and latest dates for production. The production dates use the times in the routing to determine the start and finish of production as well as of the individual operations.

  • MRP Out Put  Schedule lines date format to month

    Hi Friends,
    I am working on SAP4.7 Version.
    I have maintained all the relavent MRP datas in material master.
    Like MRP type - PD,
    Lot Size- MB ( Monthly Lot size).
    I have created planned independent requirement in MD61 monthly wise for that material.
    I have given Schedule agreement number in Source in List with MRP indicator - 2.
    I am running MRP for a material with MD02 with MRP parameter Delivery schedules -3 (Schedule lines) .
    The MRP running succesfully and creating delivery Lines with delivery dates.
    But the requirement by the client is..
    The delivery lines should be generated in month wise.
    How to convert the schedule lines generated in day format to Month format in MRP run out put?
    While creating schedule lines with ME38. we have option to select the day format / month format/ week wise?
    But the MRP out put always generated in date wise?
    Any one knows what changes i should make?
    Guide me ..
    Thanks & Best Regards

    Hi,
    The basic difference between LP and LPA  is the way that the schedules are communicated to the vendor.

  • MRP based Detailed scheduling

    HI All,
    I was setting up MRP based Detailed scheduling
    FIrst I had activated MRP based detailed scheduling in ERP
    then I CIF materials, resources, planned orders & purchase req.
    I had verified materials & resources in APO syatem.
    Then I could see the orders CIFed to APO in product view.
    then I was trying to view the orders in DS board and realise that there is no resource is linked to the orders and cannot view the orders in DS board and not able to do scheduling.
    so what should be the solution? Can anybody help me out?

    Binil,
    From your brief description, I belive you have overlooked CIFing over some Master data, either PDS or PPM.
    You must create a Production Version in R/3 first.  This contains the relationship between material and resource (which is contained in the routing).
    For an example of how to set up PP and DS, there re some nice configuration guides in SAP SCM best practices.  You will need
