Dear Tanuj,

<b>The Materials Management (MM)</b> module is fully integrated with the other modules of the SAP System. It supports all the phases of materials management from materials planning and control, purchasing, goods receiving, inventory management and the final payment to vendor using the invoice verification module.

<b>MM Process Flow</b>

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

<u>1. Determination of Requirements</u>

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.

<u>2. Source Determination</u>

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.

<u>3. Vendor Selection and Comparison of Quotations</u>

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

<u>4. Purchase Order Processing</u>

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.

<u>5. Purchase Order Follow-Up</u>

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.

<u>6. Goods Receiving and Inventory Management</u>

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.

<u>7. Invoice Verification</u>

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.

The Key areas in MATERIALS MANAGEMENT (MM);

1) Purchasing (Procurement)

2) Materials Requirement Planning (MRP)

3) Inventory Management & Physical Inventory.

In Purchasing you should have knowledge of ---

Process flow in detail. which includes

Source Determination (Source for the supply of the material)

Vendor Selection and comparison of quotations

Purchase order Processing

Purchase order Follow-up

Goods Receiving and Inventory Management

Invoice Verification

Payment processing.

In MRP-------The central role is to monitor stock and to automatically create procurement proposals for purchasing and productioni.

Material Planning Methods:

1) Consumption based Planning:

Which material to order? when to order? quantity required / quantity to order?

This method determines therequirement based on past consumption.

2) Reorder Point Planning

3) Forecast-based planning

4) Time phased planning.

In Inventory-----

Managing Stocks by quantity

Managing stocks by value

Goods Receipt

Goods Issue

Stock Transfer

Transfer Posting
