Planning, typically implemented via Material Requirements Planning (MRP), is used to

create planned orders and purchase requisitions—suggestions by the SAP system as to what should be produced on the shop floor or procured from suppliers (vendors), respectively.

The Bill of Material (BOM)

defines the relationship between materials that make up an assembled product: It is the "recipe" for a material

The planning horizon

determines how far in the future the MRP planning process looks to create production orders.

In both planning and scheduling

floats can be added to planning times to provide for a buffer against uncertainty

The Stock/requirements list

is an interactive report that provides a comprehensive set of information about a material, including inventory, planned orders, forecast demand, customer orders.

Scheduling

is the process of converting planned orders into production orders and purchase requisitions into purchase orders

Planning, which is done by the MRP process, needs:

In-house production time GR processing time Opening Period

Availability checks can be performed for:

Materials: availability of component materials Production Resources and Tools (PRT) Production Capacity

In defining plant parameters, number ranges must be defined and assigned to:

Planned orders Reservations/Dependent requirements Purchase requisitions MRP lists Simulated dependent requirement

Floats

are organized in the SAP R/3 system using Schedule Margin Keys.

In the SAP system, the person designated to manage the production and inventory levels for a material is called

called the MRP Controller.

The planned opening date can be used by

planners to convert planned orders to production orders by groups rather than individually.

The SAP system can be configured

so that a production order is released as soon as it is created. This means that the production facility can begin production.

. If more than one routing is valid for a production order, the SAP system selects

the first valid routing

Two basic methods of production order scheduling are available

-Forward Scheduling, where a production order is scheduled to start immediately and finish as soon as possible -Backward Scheduling, where the scheduling begins at the due date and works backward . Most students use backward scheduling Backward scheduling can lead to problems if there is not enough float time in the schedule to account for disruptions
