    Sales Documents

    You create a sales document to enter information about different sales transactions. R/3 provides a number

    of predefined sales document types. However , these can be customized to suit your company's needs when

    R/3 is installed.

    Some examples of sales documents include:

    • sales queries

    • sales orders

    • outline agreements

    • complaints

    You use sales queries to enter information about potential sales into R/3.Types of sales query documents

    include:

    • inquiries

    • quotations

    • free-of-charge deliveries

    An inquiry is used to record any general queries a customer may have about goods or services they

    are thinking of buying from your company. An inquiry is one of the first possible documents you can

    create in the customer order management cycle. An example of the type of information contained in an

    inquiry is whether your company stocks a certain product line. Along with entering general customer

    queries, you can use inquiries to record the goods or services that a customer is interested in. And you

    can enter descriptions of goods or services that your company should research in order to answer customer

    queries. You can carry out automatic pricing for any goods or services you enter in an inquiry. This will

    enter the price of goods or services into the inquiry for you. You can also check whether any goods you

    entered in the inquiry are available in your company's warehouse. The order probability function enables

    you to determine the likelihood that a customer will buy from you. To increase the probability of a sale,

    you can offer the customer alternative goods and services.

    Quotations are sales query documents that you create when a customer requests specific information

    about a product. For example, you can use a quotation if a customer makes a query regarding how much

    goods or services cost or you can use a query if a customer asks when goods will be available for shipping.

    You can create quotations from scratch or you can create them by copying inquiries. If a customer is

    interested in the products or services after they have made an inquiry, you can provide a quotation based

    on the original inquiry. R/3 allows you to copy the information directly from an inquiry to a quotation.

    Let's say an inquiry was created when a customer inquired whether your company, could manufacture

    twenty motorcycles. Assume a quotation was created by copying this inquiry when the customer called

    back to inquire how much twenty motorcycles would cost. You can use quotations to enter information and

    descriptions for goods and services that are to be researched. You can also use them to carry out automatic

    pricing and to check goods availability. You can use quotations to calculate the probability that a customer

    will buy the goods or services entered on a quotation. This function is called order probability.You can

    also use quotations to enter details about alternative goods or services. These are goods or services that a

    customer did not inquire about but that you think they will consider purchasing. Once you have created a

    quotation for a query in R/3, you send the quotation to the customer who made the query. The quotation

    represents a binding offer made to the customer that includes quantity and cost details.

    You create a free of charge delivery when you send free samples of any goods that your company

    produces to customers. These contain information about the goods that are delivered but they don't

    include the corresponding pricing information for them.

    Let's look at the sales orders that exist in R/3.You create a sales order when a customer has ordered

    goods or services from your company. They are a part of the customer order management cycle.

    You can carry out automatic pricing in sales orders to enter the price of goods or services.

    R/3 will also run a credit check on the customer to see if they will be exceeding their credit limit.

    You can also check whether ordered goods will be available in your company's warehouse for delivery.

    Examples of types of sales order include

    • standard orders

    • consignment orders

    • cash orders

    • rush orders

    You create standard orders for goods and services that will be delivered or rendered according to

    the standard R/3 sales cycle. This means that goods are ordered, picked from the warehouse, and

    then shipped before customers are billed for them. Likewise, services are rendered before customers

    are billed for them.

    Your company may store its goods in its customers' warehouses. You create a

    consignment order when a customer is ready to retrieve stock from the warehouse.

    SAP can propose the most suitable stock to retrieve, including third-party stock.

    A consigment order is like a standard sales order for goods but it doesn't have any delivery

    information.

    You create cash orders and rush orders for the sale of goods only.

    You create a cash order when a customer picks up and pays for a delivery as soon

    as it is ordered. And you create a rush order when the customer picks up the goods on the

    same day as the order is placed. In this case, the invoice is created later.

    You can arrange to deliver goods or render services in installments. To do this, you create an

    outline agreement. Examples of some types of outline agreement include :

    • quantity and value contracts

    • master contracts

    • scheduling agreements

    • service contracts

    You create a quantity contract if a customer has agreed to order a certain quantity

    of goods from your company during a specified period.

    And you create a value contract if a customer has agreed to order goods of a certain

    cumulative value from your company during a specified period.

    Quantity and value contracts do not include delivery dates, so releases are made

    using a sales order.

    You can unite multiple contracts in a single master contract.

    Let's say you create a quantity contract because a customer has agreed to order

    500 engines in the first six months of the current year. If the customer orders 100 of these

    engines in January, you create a sales order called a release order.You refer to a quantity

    contract in a release order. So you refer to the quantity contract created for the 500 engines in

    each release order created for these engines. R/3 will then update the quantity contract

    automatically so it contains the correct number of remaining engines to be ordered.

    Scheduling agreements specify the installments in which goods will be delivered

    to a customer. They include the quantity of a product that will be delivered in each

    installment. And they include the delivery date of each installment. You process a delivery

    for each installment contained in the scheduling agreement in the same way that you process

    a delivery for a regular sales order.No sales documents, such as release orders, are created before

    the products included on a scheduling agreement are processed for delivery.

    You create a service contract if a customer requests a service over a particular

    period of time.For example, you could create a service contract if a customer ordered five

    one-hour maintenance checks from your company's motorcycle repair department.

    You create complaint sales documents if there has been a fault with any goods that

    have been delivered, or with any services rendered, by your company.

    For example, you create complaint sales documents if customers have been billed

    incorrectly for an item or service, or if goods are faulty.

    Different types of complaint sales document include

    • returns

    • credit memo requests

    • debit memo requests

    You create a returns document if a customer returns goods they have purchased from

    you because they are not satisfied with them. You can create returns from scratch or you can

    create them by copying the sales order that was originally created for the returned delivery.

    A returns document records that you expect stock to be returned to your warehouse.

    You can create one or more credit memo requests if a customer has been overcharged

    for a quantity of goods or services. You can also create a credit memo request if goods were

    damaged during transit and you want to credit the customer for the goods damaged.

    When you create a credit memo request, your Accounting department reviews it to

    confirm that it can be justified. If the credit memo request is approved, the Accounting department

    creates a credit memo based on the request. You can create credit memo requests by copying other

    sales documents such as the sales order where the overcharge occurred.

    You create debit memo requests when customers have been undercharged for products

    or services.Your company’s Accounting department can then create an invoice to bill the

    undercharged customer.

    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.

    <b>call session method in BDC</b>

    In this method you transfer data from internal table to database table through sessions.

    In this method, an ABAP/4 program reads the external data that is to be entered in the SAP System and stores the data in session. A session stores the actions that are required to enter your data using normal SAP transaction i.e., Data is transferred to session which in turn transfers data to database table.

    Session is intermediate step between internal table and database table. Data along with its action is stored in session i.e., data for screen fields, to which screen it is passed, the program name behind it, and how the next screen is processed.

    When the program has finished generating the session, you can run the session to execute the SAP transactions in it. You can either explicitly start and monitor a session or have the session run in the background processing system.

    Unless session is processed, the data is not transferred to database table.

    BDC_OPEN_GROUP

    You create the session through program by BDC_OPEN_GROUP function.

    Parameters to this function are:

    • User Name: User name

    • Group: Name of the session

    • Lock Date: The date on which you want to process the session.

    • Keep: This parameter is passed as ‘X’ when you want to retain session after

    processing it or ‘ ‘ to delete it after processing.

    BDC_INSERT

    This function creates the session & data is transferred to Session.

    Parameters to this function are:

    • Tcode: Transaction Name

    • Dynprotab: BDC Data

    BDC_CLOSE_GROUP

    This function closes the BDC Group. No Parameters.

    Some additional information for session processing

    When the session is generated using the KEEP option within the BDC_OPEN_GROUP, the system always keeps the sessions in the queue, whether it has been processed successfully or not.

    However, if the session is processed, you have to delete it manually. When session processing is completed successfully while KEEP option was not set, it will be removed automatically from the session queue. Log is not removed for that session.

    If the batch-input session is terminated with errors, then it appears in the list of INCORRECT session and it can be processed again. To correct incorrect session, you can analyze the session. The Analysis function allows to determine which screen and value has produced the error. If you find small errors in data, you can correct them interactively, otherwise you need to modify batch input program, which has generated the session or many times even the data file.
