Hi,
MM Flow:
The dataflow as functional process below are the points:
1) Purchasing Requsition -> sent by inventory dept to purcharsing dept
2) Request for Quotation(RFQ)-> Purchasing Dept shall ask the vendors to give the quotation for the requested materials by inventory.
3) Quotation -> Quotation is sent by vendors to the company
4) Purchase order-> Based on all paramers of a quotation sent by vendors. Vendors are selected from whom the material has to be obtained.  The company  gives  purchase order to the vendor.
5) Good's receipt -> vendors sends the goods to the company with goods receipt
6) Invoice verification ->  this done based on good's receipt. this means that the ordered goods have reached or not.
7) Payment -> payment is done based on invoice verification. this is (FI/CO)   *-- Santosh Kumaar.M

SD Flow:
Document Flow in Sales
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.
