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

Production Planning:
For example, consider a pump manufacturing plant, based on the customer requirement, planning is done for future months ( we plan for a qty on particular
date). Pump is an assembly - were main component would be manufactured in the plant and others would be procured. As PP, we are concerned only in the inhouse
manufacturing but the final assembly (considering BOM) can be done only if the procured components are available. MRP helps in planning the shortage, on
particular date based on the planned date. Work center (ex. lathe) place the components are machined/assembled (were the operation is done). Sequence of
operation is routing (lead time scheduling data is got from routing). In the MRP Run,basic or lead time scheduling (need to know when to start/finish date)
is done. On creation of the production order, system checks for which BOM and routing to be picked up (if there are many routings or BOM for that particular
finished product). Availabilty checks for material,PRT and capacity needs to be done. on release of the order, confirmation of the order can be done (on
completion of the order or after manufacturing the quantities). GI and GR have to be done.PP flow ends here
step 1: creation of master data (Material master,BOM,Work center,Routing)
step 2: Planning - can be done by Planned independent requirement (MD61), Independent requirement (MD81).
we plan for a quantity, on which date (it would be finish date).
step 3: MD04 -stock/requirement lsit (plan made can be viewed in MD04)
step 4: MRP run - MD02, PIR is converted into Planned order
step 5:Planned order to be converted production order - CO40, CO41
step 6: production order to be released - CA02
step 7: confirm the production order (order confirmation-CO15 (after which GI and GR is done)
