1. SAP Purchasing
Prepared by Lavanya .M

2. 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 Purchasing component 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.

3. 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.

• Reports are collection of records that are
helpful for arriving at important decisions.
• Reports can be filtered based on requirements
parameters. For e.g., TCode MM60 we can filter
