The purpose of MRP is to guarantee material availability by planning for procurement or production of required quantities.

How the Planning Run Works
Net Requirements Calculation1. Determine Available Warehouse Stock 2. Determine Planned Receipts (after considering existing issues and receipts)3. Calculate the Shortage Quantity
Lot Size CalculationDetermine the lot size of each plan order. R3 Lot Sizing falls into 3categories : Static Lot Size, Optimum Lot Size or Period Lot Size
Procurement Type & SchedulingIn-house Production or External Procurement & Backward Scheduling orForward Scheduling
BOM ExplosionDetermine the valid BOM for explosion
Quota ArrangementA lot can further be split by quota arrangements (MM will cover this)

MRP will compare the requirement and supply to get a shortage gap. A comparison is made between warehouse stock and the appropriate receipts and issue. In the net requirements calculation, a difference is made between reorder point planning, forecast-based planning, and MRP. In each procedure, the system calculates available stock differently.

How the Planning Run Works Per MRP Type
Reorder Point Planning (REORDER) (MRP Type VB, Reorder Level)
When Available Stock falls below reorder level, planned orders are
generated in the planning run to order up to reorder level. Safety Stock
requirement is just for information
Available Stock = Plant Stock + ReceiptsAvailable Stock = Plant Stock + Receipts
Reorder Point Planning + Requirements (REORDERREQS) (MRP Type V1,
Reorder Level)
When Available stock falls below reorder level, planned orders are generated in the planning run to order up to reorder level. Safety stock requirement is just for information. The difference here is that sales orders and reservations are also taken into account.
Available Stock = Plant Stock + Receipts - (Sales Orders + ReservationsAvailable Stock = Plant Stock + Receipts - (Sales Orders + Reservations))
SAP AG 2001, A Business View of mySAP Financials, GBU FIN - 12
How the Planning Run Works Per MRP Type
Forecast Based Planning (FORECAST) (MRP Type VV, Create Forecast)System only considers forecast requirements (any other requirements are not considered). Planned orders are proposed when available stock is less than forecast requirements.Available Stock = Plant stock - Safety Stock + Receipts - Forecast RequirementsAvailable Stock = Plant stock - Safety Stock + Receipts - Forecast Requirements
Time Phased Planning (TIMEPLAN) (MRP Type R1, Planning Cycle, CreateForecast)
Material is planned according to same cycle in which it is delivered ie the material is not planned during the normal MRP run. The material have to be planned using a separate MRP run. Available Stock = (Plant stock - Safety Stock + Receipts - Forecast Requirements) Available Stock = (Plant stock - Safety Stock + Receipts - Forecast Requirements) within the planning cyclewithin the planning cycle.
MRP Planned (PDFORECAST) (MRP Type PD, Optional Create Forecast)System checks every requirement to determine whether they are covered by available warehouse stock and/or receipts.Available Stock = Plant stock - Safety Stock + Receipts - All RequirementsAvailable Stock = Plant stock - Safety Stock + Receipts - All Requirements

The following times are taken into account : processing time required by purchasing
department (workdays) planned delivery time of the material (calendar
days) goods receipt processing time (workdays)

Planning Time Fence
Plan is protected from changes within the planning time fence.
End date of time fence determined from planning date.
You can configure system as to how you want the orders to react within the time fence.
Outside the time fence, system creates order proposal as usual.
When new orders move into the time fence, they may be firmed automatically depending on how the system is configured.

Evaluating the Planning Run
• MRP List By Material
• MRP List Collective Display
• Stock Requirements List By Material
• Stock Requirements List Collective Display
• Compare MRP List against Stock Requirement List
• Planning situation for Material - (same as stock requirement list ie latest situation for a material)
• Planning result for material - (the last MRP run for the material) - you can compare your current plan against long term planning scenarios or stock requirements list here.
• Situation (all plants) - Review planning situation (ie stock requirement list) for material for all plants
• Order Report - Review your orders in the order report
• Pegged Requirements - Review Pegging

Implementation Decisions
• Group materials with common planning profile together.• Decide an MRP Type for each group of materials.• Decide what the lot sizing should be for each material/group of
materials.• Decide for each material, whether you require safety stock and if
safety stock is required, what method of planning the safety stock ?
• Which material require quota arrangements ?• What are the materials that have to be procured from another
plant ? • Are there any storage locations to be blocked from planning ?• Are there storage locations/MRP area needed to be planned
separately ?
