    Hello Pankaj ,

    Material requirements planning (MRP) is a production planning and inventory control system used to manage manufacturing processes. Most MRP systems are software-based, while it is possible to conduct MRP by hand as well.

    An MRP system is intended to simultaneously meet three objectives:

    Ensure materials are available for production and products are available for delivery to customers.

    Maintain the lowest possible level of inventory.

    Plan manufacturing activities, delivery schedules and purchasing activities.

    The Master Production Schedule gives production, planning, purchasing, and top management the information needed to plan and control the manufacturing operation. The application ties overall business planning and forecasting to detail operations through the Master Production Schedule.

    The Master Production Schedule will drive detailed material and production requirements in the Material Requirements Planning module. Genrerally,

    MPS is executed for critical components followed bt MRP for susequent component/dependent requirement.

    This just the tip of information about MRP and MPS. You can find tons of info in wikipedia, help.sap portal and other sites .

    If you have any particular question about MRP or MPS then let us know .

    I hope the information helps

    Cheers

    Hi

    MRP Procedures

    The aim of material requirements planning is to tailor available capacities and receipts on time to suit requirements quantities. You can use MRP or consumption-based planning for this. A special form of MRP is master production scheduling.

    u2022 Material requirements planning : (MRP Type: PD) is carried out using current and future sales figures. The planned and the exact requirements quantities trigger the net requirements calculation.

    u2022 In Master production scheduling, (MPS Type: M1,M2, M3,M4) finished products and important assemblies, so-called master schedule items, are planned separately and with extra attention. Only the master schedule items are planned in this planning run. The system creates dependent requirements for the BOM level directly below the planning level. It does not, however, plan levels below this.

    Master Production Scheduling Procedure

    u2022 You have set an MRP type for master production scheduling in the material master (MRP 1 view).

    u2022 You have entered a planning time fence.

    o You can define a planning time fence per material or you can also use the MRP group in the material master to assign a planning time fence to a material. The planning time fence that you assign manually has priority over the planning time fence in the MRP group.

    o The firming type, which you have defined in Customizing, determines whether the system is to create procurement proposals for material shortage in the planning time fence and You start the total planning run for master schedule items or single-item planning for master schedule items..

    Planning Time Fence

    You can protect procurement proposals from any automatic changes to master schedule items in the near future by using the planning time fence. Within the planning time fence, the system does not automatically change procurement proposals during the planning run. That is particularly useful for MPS.

    You can define the planning time fence either material-specific or per MRP group. The material-specific setting overwrites the MRP group setting.

    All procurement proposal types are firmed within the planning time fence:

    u2022 planned orders

    u2022 purchase requisitions

    u2022 Delivery schedules (schedule lines).

    Firming Type

    The firming type determines how procurement proposals are to be firmed and scheduled within the planning time fence during the planning run.

    The following firming types are available:

    u2022 firming type 0

    The system does not firm procurement proposals automatically.

    u2022 firming type 1 : MRP Type: P1

    Procurement proposals that move into the planning time fence are firmed automatically, as soon as their date lies at least one day before the end date of the planning time fence. The date of new procurement proposals that are created in the planning time fence is displaced to the end of the planning time fence. These new procurement proposals are not firmed.

    u2022 firming type 2 : MRP Type:P2

    Procurement proposals that move into the planning time fence are firmed automatically, as soon as their date lies at least one day before the end date of the planning time fence. The system does not create any new procurement proposals within the planning time fence; that means, the system does not balance the shortage situation in the planning time fence.

    u2022 firming type 3 : MRP Type: P3

    Procurement proposals that move into the planning time fence are not firmed automatically by the system. All procurement proposals that are necessary for requirements coverage are displaced to the end of the planning time fence.

    u2022 firming type 4 : MRP Type:P4

    Procurement proposals that move into the planning time fence are not firmed automatically by the system. The system does not create any new procurement proposals within the planning time fence; that means, the system does not balance the shortage situation in the planning time fence.

    MRP Type: ZT

    Same as that of MRP Type: PD

    Only the description changed to ZT (ZT will function like PD)

    Hope , this will help
