Purchasing

The R/3 System consists of a number of components that are completely integrated with one

another. This integration allows the various departments and units of an enterprise to share and

maintain the same information.

Purchasing is a component of Materials Management (MM). The Materials Management (MM)

module is fully integrated with the other modules of the SAP System. It supports all the phases of

materials management: materials planning and control, purchasing, goods receiving, inventory

management, and invoice verification.

The tasks of the MM Purchasingcomponent are as follows:

External procurement of materials and services

Determination of possible sources of supply for a requirement identified by the materials

planning and control system or arising directly within a user department

Monitoring of deliveries from and payments to vendors

Good communication between all participants in the procurement process is necessary for

Purchasing to function smoothly.

Purchase Order Processing

The Purchasing system adopts information from

the requisition and the quotation to create a

purchase order.

As with purchase requisitions, we can generate POs

or have the system generate them automatically.

Vendor scheduling agreements and contracts (in

the SAP System, types of longer-term purchase

agreement) are also supported.
