### Requirements Planning Overview

JD Edwards EnterpriseOne Requirements Planning is part of Oracle's JD Edwards EnterpriseOne Supply Chain Management product line. Supply Chain Management (SCM) enables you to coordinate inventory, raw materials, and labor resources to deliver products according to a managed schedule. This closed-loop manufacturing system helps you manage data and optimize resources across the entire manufacturing and distribution logistics environment. SCM formalizes the activities of company and operations planning.

### Requirements Planning Features

JD Edwards EnterpriseOne Requirements Planning consists of these features:

Resource and Capacity Planning

Resource and Capacity Planning enables you to prepare a feasible production schedule that reflects demand forecasts and production capability. Resource and Capacity Planning consists of:

- Resource Requirements Planning (RRP)

  Uses a detail or summary forecast to estimate the time and resources that are needed to make a product family.

- Rough Cut Capacity Planning (RCCP)

  Compares the resource requirements from master production scheduling to the capacity that is available in critical work centers.

  You use RCCP to determine whether you should revise the master schedule to create feasible workloads or improve the use of limited resources.

- Capacity Requirements Planning (CRP)

  Compares the material requirements plans to the capacity available in all work centers.

  You use CRP to determine whether you should revise the material requirements plan to create feasible workloads or improve the use of the resources.

Material Planning Operations

Material Planning Operations provides a short-range plan to cover material requirements that are needed to make a product. Material Planning Operations analyzes demand from all the operational areas, including:

- Central and satellite distribution centers and warehouses.

- Items that are manufactured in both discrete and process environments.

- Engineer-to-order contracted items.

- Maintenance, repair, and operational items for plant and equipment maintenance.

- Supplier-managed inventory.

Material Planning Operations consists of these feature sets:

- Distribution Requirements Planning (DRP)

  Plans and controls the distribution of finished goods, based upon demand.

- Master Production Scheduling (MPS)

  Creates a schedule of items and quantities that a company expects to manufacture.

- Material Requirements Planning (MRP)

  Uses the master production schedule, open orders, bills of material, and inventory records to calculate time-phased net requirements for every item, and creates a plan for covering material requirements.

- Multifacility Planning

  Provides centralized control of distribution inventories and creates a coordinated replenishment plan.

- Project Requirements Planning (PRP)

  Uses work breakdown structures from projects and related bills of material to create replenishment plans for project items.

Project Requirements Planning (PRP)

PRP is an option within the MRP/MPS Requirements Planning program (R3482) that you use to generate replenishment schedules for production orders and components for an end item that are used in a project.

PRP recognizes the shippable items from the project as the supply of the end item and uses this supply to drive the demand for its components. Thus, the project supplies its own demand.

The system generates dependent demand by using the bill of material (BOM) structure or the work order parts list that is associated with the end items. Inventory that is acquired either by purchase order receipts or work order completions for these project-specific items should be used only for meeting the project's demand.

The system regards the project demand and supply as standalone or independent so that any additional demand or supply from forecasts, sales orders, work orders, or purchase orders on the end item does not interfere with the requirement from the project.

Supplier Scheduling Systems

A dependency on goods and services from other organizations has increased the need to establish planning and information methods between the supplying links of a supply chain.

Through supplier scheduling, planners can provide suppliers with consistent shipping information and demand profiles to support production and delivery. Planners negotiate order contracts between consumer and supplier through scheduling tools. Order contracts are often defined as blanket orders with established quantities for a demand company. When a company forms a supply chain with a scheduling system, a supplier has accurate data to project plans for demand forecasts, ordering, production, and delivery. A consuming company benefits because its deliveries from a supplier are dependable. Enterprises can make point-of-use deliveries from the exact location where the supplier delivers the goods to the production location that consumes products. Instead of supplying inventory to stores or warehouses for dissemination, enterprises can deliver from the point of use.

Partnership contracts between companies reduce inventory-carrying costs, production lead times, and time-to-market for products. An enterprise uses supplier-scheduling methodologies to share planning information across business boundaries. Scheduling enables contributors to a product line to develop schedules that originate from known information. When schedules change, especially in dynamic industries such as electronics and automotive, the demand and supply partners establish communication links to accommodate changes as quickly as possible.

### Requirements Planning Tables

These tables are used throughout the JD Edwards EnterpriseOne Requirements Planning system:

Table | Description
Item Master (F4101) | Contains basic information about each item that is defined in inventory, such as: Item numbers and descriptions Category codes Units of measure
Item Branch File (F4102) | Contains warehouse or plant-level information, such as: Costs Quantities Location Branch level category codes Lead times Planning fences Order policy codes
Bill of Material Master File (F3002) | Contains information at the business unit level about bills of material, such as: Costs and quantities of components. Features and options. Levels of detail for each bill.
Capacity Message File (F3311) | Contains the action messages that are generated by the RRP, RCCP, and CRP programs.
Forecast File (F3460) | Contains the forecast data that MPS uses for calculations and that RRP validates.
Routing Master File (F3003) | Stores routing information, including operation sequence, work center, run, setup, and machine time.
Work Center Resource Units (F3007) | Contains the available capacity for each work center by day, month, and year.
Work Center Master File (F30006) | Contains detail data about all defined work centers.
Capacity Resource Profile (F3303) | Contains all of the resource profiles that are used in Resource Requirements Planning.
Branch Relationships Master File (F3403) | Contains the supply and demand relationship among the branches.
MPS/MRP/DRP Message File (F3411) | Contains the action messages that are generated by MPS, MRP, or DRP.
MPS/MRP/DRP Lower Level Requirements File (F3412) | Contains the source of gross requirements that are posted to items from parent items.
MPS/MRP/DRP Summary File (F3413) | Contains the time series data for forms and reports.
Supplier Schedule Master File (F4321) | Contains most of the data that controls scheduling arrangements with the supplier. This table also contains information that is required for creating and maintaining the schedule, including: Ship lead time Schedule days Ship pattern Shipment quantity Delivery location The system uses information from the Supplier Schedule Master File table for each line item on a blanket order that you use in the supplier scheduling process.
Supplier Schedule Master File (F43211) | Contains the data that identifies predetermined split percentages between suppliers, by item.
