Hi ABAP Gurus,

I want to know the detail description of MM flow and its related tables and related fields with one nice example.

i mainly want the links (tables, fields) in particular.

Thanks & Regards.

Hi,

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

Hi,

MM Flow:

MM Cycle:

Purchase Requisition-> STaff in an orgn places Pur requisition for want of some goods/products - ME51

Request for Quotation(RFQ)-> The Purchase dept in the orgn calls/requests for the quotation for the products against which PR was raised. - ME41

Vendor Evaluation->After receving the RFQ's, after comparison a Vendor is finalised based on the terms and conditions.

Purchase Order(PO)-> Pur order was issued to that vendor asking him to supply the goods/products -ME21N

Goods Receipt Note(GRN)->Vendor supplies the material/Products to the orgn-

MB01

Goods Issue (GI) -> People receives their respective itesm for which they have placed the Requisitions

Invoice Verification-> ALong with the Material Vendor submits a Invoice for which the Company Pays the amount - .MIRO

Data to FI -> data will be posted to FI as per the vendor invoices

hi,

hi,

The dataflow as functional process of mm, 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

The FI - MM integration:

First you define the g/l master records.

1) Inventry raw material a/c

2) GR/IR clearing a/c

3) Raw material consumption a/c

Above like this you define all required g/l accounts

then you will go to T.CODE - OBYC

Double click BSX (this is transaction key)

" GBB

" WRX

" PRD

These are transaction keys important.

Then you go to T CODE - OMSY (this is also important) then

Material creation T Code MM01

then

1) Purchase order T.code ME21N

2) Goods received " MIGO

3) Invoice verification " MIRO

The FI - MM integration finished
