    MM Process flow:

    Process Flow

    The typical procurement cycle for a service or material consists of the following phases:

    1. Determination of Requirements

    Materials requirements are identified either in the user departments or via materials planning and control. (This can cover both MRP proper and the demand-based approach to inventory control. The regular checking of stock levels of materials defined by master records, use of the order-point method, and forecasting on the basis of past usage are important aspects of the latter.) You can enter purchase requisitions yourself, or they can be generated automatically by the materials planning and control system.

    2. Source Determination

    The Purchasing component helps you identify potential sources of supply based on past orders and existing longer-term purchase agreements. This speeds the process of creating requests for quotation (RFQs), which can be sent to vendors electronically via SAP EDI, if desired.

    3. Vendor Selection and Comparison of Quotations

    The system is capable of simulating pricing scenarios, allowing you to compare a number of different quotations. Rejection letters can be sent automatically.

    4. Purchase Order Processing

    The Purchasing system adopts information from the requisition and the quotation to help you create a purchase order. As with purchase requisitions, you can generate Pos yourself 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.

    5. Purchase Order Follow-Up

    The system checks the reminder periods you have specified and - if necessary - automatically prints reminders or expediters at the predefined intervals. It also provides you with an up-to-date status of all purchase requisitions, quotations, and purchase orders.

    6. Goods Receiving and Inventory Management

    Goods Receiving personnel can confirm the receipt of goods simply by entering the Po number. By specifying permissible tolerances, buyers can limit over- and under deliveries of ordered goods.

    7. Invoice Verification

    The system supports the checking and matching of invoices. The accounts payable clerk is notified of quantity and price variances because the system has access to PO and goods receipt data. This speeds the process of auditing and clearing invoices for payment.

    Pur info record is nothing but a master data like thing which will be maintained for different materials to determine the prices etc.It Specifies the number that uniquely identifies a record.

    For Example: an info record is based on Plant Vendor and Material

    Based on these three the Material Prices will be calculated

    for different combinations different values are taken into consideration.

    During pricing it brings these values automatically based on this info record.

    Use ME11 Tcode to create this record.
