ABAP術語-Transaction

Transaction

原文：http://www.cnblogs.com/qiangsheng/archive/2008/03/19/1112804.html

Logical process in the R/3 System. From the user’s point of view, a transaction is a self-contained unit (for example, generate a list of customers, change the address of a customer, book a flight reservation for a customer, execute a program). From a dialog programming point of view, a transaction is a complex object that consists of a module pool and screens, and is called by specifying a transaction code. After logon, there are 3 distinct levels in the R/3 System: R/3 level, Work area level, and Application level. A transaction is an application at application level. To go to the initial screen of an application, you can either navigate through the menus by choosing the appropriate menu options or enter the appropriate 4-character transaction code in the command field. Using the transaction code saves navigation through the menus and takes the user directly to the initial screen. Example: To call the ABAP Editor from the initial screen of the R/3 System, you either choose Tools -> ABAP Workbench -> ABAP Editor, or enter the transaction code SE38 in the command field.
