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

VBAK: Sales Document(Header Data) (VBELN)
VBAP: Sales Document(Item Data) (VBELN,POSNR,MATNR,ARKTX,CHARG)
Enquiry, Quotation, Sales Order are differentiated based on Doc.
Type(VBTYP field) in VBAK,VBAP Tables( for Enquiry VBTYP = A,
for Quotation 'B' & for Order it is 'C'.)
LIKP: Delivery Table (Header Data)(VBELN,LFART,KUNNR,WADAT,INCO1)
LIPS: Delivery Table (Item Data)(VBELN,POSNR,WERKS,LGORT,MATNR,VGBEL)
(LIPS-VGBEL = VBAK-VBELN, LIPS-VGPOS = VBAP-POSNR)
VTTK: Shipment Table (Header Data)(TKNUM)
VTTP: Shipment Table (Item Data)( TKNUM,TPNUM,VBELN)
(VTTP-VBELN = LIKP-VBELN)
VTFA: Shipping Document Flow(TKNUM,VBELV,VBELN)
VTPA: Shipping Partners data(VBELN,PARVW,KUNNR,PERNR)
VTTS: Stages in Shipment(TKNUM,TSNUM,TSTYP)
VTSP: Transport Stage/Shipment Item Allocation(TKNUM,TSNUM,TPNUM)
VEKP: Handling Unit: Header(Packing)(VENUM,VSTEL)
VEPO: Handling Unit: Item (Packing)(VENUM,VEPOS,VBELN)
VBRK: Billing Table(Header Data)(VBELN,FKART,BELNR)
VBRP: Billing Table(Item Data)(VBELN,POSNR,FKIMG,NETWR,VGBEL,VGPOS)
(VBRP-AUBEL = VBAK-VBELN, VBRP-VGBEL = LIKP-VBELN)
Apart from these tables there are lot of other tables which starts with
‘V’, but we use the following tables frequently.
VBUK: All Sales Documents status & Admn. Data(Header)(VBELN,VBTYP)
VBTYP= ‘C’(Sales Order) VBTYP=’J’(Delivery) VBTYP=’M’(Invoice)
VBUP: Sales Documents status & Admn. Data(Item)(VBELN,POSNR)
MM
EBAN-- Pur.Reqn. Data (BANFN,BNFPO,BADAT,MATNR)
EBKN-- Purchase Requisition Account Assignment(BANFN,BNFPO,VBELN)
EINA—- Purchase Info.Record (General Data)(INFNR,MATNR,LIFNR)
EINE-- Purchase Info.Record (Pur.Orgn Data )(INFNR,EKORG)

ELBM-- Vendor Evaluation: Material-Related Item(LIFNR,MATNR,EKORG,INFNR,HKRIT)
ELBP—- Main Criteria for Vendor Evaluation (LIFNR,EKORG,HKRIT)
EKKO-- Purchase Order Data (Header)(EBELN,BSTYP,BSART)

RFQ and PO are differentiated by Doc Type(BSTYP)in EKKO table.
For RFQ it is ‘A’ and for PO it is ‘F’.
MKPF-- GRN Data (Header) (EBELN,BLDAT,BUDAT,XBLNR,BKTXT)
MSEG-- GRN Data (Item)(MBLNR,BWART,LIFNR,MATNR,EBELN)
The link between SD and MM :-
1. When you create sales order in SD, all the details of the items are copied from Material master of MM.
2. MRP and availibility check related data is also taken from MM although you control this data in SD also.
3. While you create inbound/outbound delivery with reference to a sales order,the shipping point determination takes place with the help of the loading group, plant data, shipping conditions etc. This also refers to Material Master.
4. The material which you are entering in a sales order must be extended to the sales area of your sales order/customer otherwise you cannot transact with this material.
