Hi,

MM 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 underdeliveries 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.

SD Process Flow:

The sales documents you create are individual documents but they can also form part of a chain of inter-related documents. For example, you may record a customer’s telephone inquiry in the system. The customer next requests a quotation, which you then create by referring to the inquiry. The customer later places an order on the basis of the quotation and you create a sales order with reference to the quotation. You ship the goods and bill the customer. After delivery of the goods, the customer claims credit for some damaged goods and you create a free-of-charge delivery with reference to the sales order. The entire chain of documents – the inquiry, the quotation, the sales order, the delivery, the invoice, and the subsequent delivery free of charge – creates a document flow or history. The flow of data from one document into another reduces manual activity and makes problem resolution easier. Inquiry and quotation management in the Sales Information System help you to plan and control your sales.

Transaction Codes:

Inquiry - VA11/VA12/VA13

Quotation - VA21/VA22/VA23

Sales Order - VA01/VA02/VA03

Delivery - VL01N/VL02N/VL03N

Billing/Invoicing - VF01/VF02/VF03

Hi sandeep G ,

In SD we sell goods & we invoice the customer.

what goods we are selling , their details like what is the material, what is the material group of this material, where it is stored , what is its material description ....etc. all these details are derived from MM tables i.e MARA,MAKT(Material Description), MARD, MAST, MARC........etc.

So, this how SD & MM are related.

If u stil have doubt pls let me know.

cheers!
