Answer 1

The typical procurement cycle for a service or material consists of the following phases:
1. Determination of Requirements (MD02 / ME51N): - 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 (ME41 / ME47 / ME49): - 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 (ME21N): - 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 (MIGO): - 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 (MIRO): - 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.
Rebate Process:
1. XK02 - Changing a Vendor Master Record (Activate "Subsequent Settlement" and "Sebseq. sett. index" in Purchasing view)
2. MEB1 - Creating a Rebate Arrangement
3. ME21N - Creating a Purchase Order
4. MIGO - Processing the Goods Receipt for the Purchase Order
5. MIRO - Processing the Incoming Invoice on the Basis of a Purchase Order
6. MEB4 - Creating an Interim Settlement
7. MEU2 - Creating a Business Volume Comparison
8. MEB2 - Creating a Final Settlement
A centrally agreed contract is involved if:
A single purchasing organization procures for an entire corporate group, or
A reference purchasing organization makes a contract available to other associated purchasing organizations, enabling the latter to issue release orders against this contract
Centrally Agreed Contracts are created in same transaction ME31K, but here is some difference in maintaining the pricing conditions and partner functions.
Maintaining Plant Conditions
1. When maintaining the centrally agreed contract, choose Edit > Plant conditions > Overview.
2. On the overview screen that then appears, enter the desired plant and choose "Overview" icon Plant prices.
3. An item overview screen appears, starting from which you can maintain conditions.
Choose Item > Conditions to access the condition maintenance screen.
4. Return to the overview and repeat the process for all plants for which you wish to store plant-specific conditions.
5. Save your input.
Maintaining Partners
You can maintain the different partners either in the vendor master record or individually in the contract. If the partners have been maintained in the vendor master, they are suggested in the contract.
Maintaining partners in a contract
1. In the contract, choose Header > Partners.
2. The Data Retention Level: Partners screen appears. Enter the plant and/or vendor sub-range, and choose ENTER. The Maintain Partners screen appears.
Note
To see which partners have already been maintained, select the desired item and choose "Display" button Level.
3. Enter the desired partner and return to the item overview for the contract.
4. Save your input.
Maintaining partners in the vendor master
1. Choose Extras > Different data on the Partner Roles (partner functions) screen in the vendor master record.
2. On the Create Different Data screen, enter the plant or vendor sub-range and select Partner Roles.
3. Click "Enter" button. The Change Vendor: Partner Roles screen appears.
