Sap mm module Overview

 

SAP is divided into several relatively large modules. Although each module is connected, it also has a certain degree of independence. users may only purchase a certain number of modules and then perform secondary development. ABAP is mainly used. A language dedicated for Secondary Development of SAP. work with other systems. the information management of the entire company can be realized.

SAP is highly configurable. It can be applied to all industries and may be used differently in different industries. in my introduction, the manufacturing industry is used as an example. compare sap with the database. in fact, I personally think we can regard sap as a more complex database. it not only saves a large amount of data, but also a large number of methods to perform various complex operations on the data. of course, this can only be explained at a certain level of abstraction. in fact, like many other systems, the SAP system only performs various operations on data. the data is stored in the background database.

The mm module mainly involves procurement of raw materials, storage and transfer of materials in stock.

We have to rely on people to do what we do. Some people have to have an organizational structure to facilitate management. the organizational structure of the MM module is mainly company, plant, and store ). this is a tree structure from top to bottom. clients (groups) may be at the top of a large company ). another company may have a general procurement organization (purchase Orgnization ). if each plant has its own procurement organization. in reality, we see departments.

In SAP, how does one express the organizational structure. the SAP system does not know the organization structure of the customer's company in advance. this requires configuration. company, plant, and store may be like an object-oriented class. Many objects need to be instantiated when used. so we need to create some company, plant. just like creating tables or other objects in a database. set related attributes and constraints.

The most important thing about material management is material. materials can include raw materials, semi-finished products, or finished products. we can further classify the materials in detail. record the quantity, size, and warehouse information in the system. A unique serial number can be provided for the first generation. it is like creating many tables in a database, and then having some primary keys. of course, the supplier information also needs to be recorded.

SAP actually refers to the informationization of the company's business processes. Let's talk about the procurement business process first, and then we will probably implement it in SAP.

1. procurement request: before purchasing, you must first have a purchase request. What kind of stuff do you need to buy? What is the quantity. this information is mainly sent from other modules, such as PP (product plan ). SD (sales distribution ). we have to estimate how many products will be sold according to the sales volume, so we can purchase materials based on the productivity of the factory and how much money the property department can provide. determine the quantity of materials to be purchased based on many conditions.

2. supplier Selection: When the purchasing department receives the purchase order, it will select the supplier. If you have a meal, the kickback system will not be able to handle the problem. the system only scores suppliers based on their prices and their reputation. then you can pick a high score to purchase. when a supplier is selected and the price is negotiated, the order will be officially placed.

3. payment for goods acceptance: the supplier will ship the goods after receiving the order. then the warehouse personnel receive the goods and inspect the goods. then the property department will pay for it. then the supplier issues the invoice for you. after the goods are delivered, inventory management should be performed in the warehouse. in addition, you may have to return the goods if they fail to pass the goods inspection.

What are the specific operations in sap. generally, the C/S mode is used. install a client, open the server information you want to connect to, and enter the user name and password. Different users may have different permissions. this is similar to database operations. some graphical interfaces will appear after logging in. tree-like list. you can click some options to view some information or place an order. in fact, it is equivalent to searching tables in the database. create a table. however, the table contains many table templates. You only need to fill in some information. in addition, some commands can be entered to directly execute the corresponding operations. the operation is the same as in the command line in the operating system.

In the procurement process, the most important operation in SAP is to fill in the purchase order (purchase order ). if the information is complete, you do not need to enter it manually. The system can automatically generate the information for you. you can finally list the list. just like some lists we usually see.
