Sap abap Development

ABAP authentication is a type of SAP authentication. It indicates that ABAP authentication has the secondary development capability of the SAP module. ABAP developers provide effective and quick information to management personnel. The person who opens the ABAP will have a deep understanding of the enterprise business and sap erp system.

SAP initially developed the ABAP language for internal use only to provide an optimized working environment for application programmers. It has been constantly improved and modified to meet business needs. The current version is ABAP/4, and ABAP/4 has become the only tool for SAP to develop all its own application procedures.

ABAP is the fourth generation of languages that support structured programming. It combines all common control structures and modular concepts. At the same time, it also supports object-oriented programming methods, which opens up a broader space for application development of ABAP. It can also be integrated with other programming languages, such as VB, Java, C/C ++.

The difference between ABAP and many programming languages is that it is not just in a vacuum, waiting for the application to be developed. Applications already exist in the form of classic R/3 modules, BW and SEM. Our job is to enable these applications to complete more tasks than originally designed for SAP. This requires an understanding of these applications, data structures, and processes. You can only get these understandings through practical experience.

ABAP has two main program types:

First: Report Program

A report program is used to analyze data in a database table. The analysis results can be displayed on the screen or sent to the printer. Logical databases support Report programs. Logical database is a special ABAP/4 program, so that developers do not have to code all database access. (For more information, Baidu: 51sap practical center)

Type 2: Dialog Program

Organize the dialog program into a module pool that contains the dialog module. Each dynamic program (a "dynamic program" composed of a screen and Its stream logic) is based on an ABAP/4 dialog program. The stream logic includes the call to the ABAP/4 dialog module.

ABAP certification only indicates that the certification owner has reached a certain level of knowledge. It does not explain how to apply this knowledge, nor does it mean that the certification owner has the relevant capabilities in general programming. However, having certification is a favorable condition, so we can be certain that they have at least a certain understanding of related technologies. In addition, by registering for the ABAP certification, You can continuously learn relevant knowledge about the ABAP. In this case, if you pass the ABAP authentication, you have already entered the sap door. As long as you continue to learn sap-related knowledge and technology in the future, a larger development space is waiting for you!
