ABAP中可用的各种变量类型。 ABAP中有三种变量 - •Static Variables 静态变量 •Reference Variables 参考变量 •System Variables 系统变量 静态变量 (这里暂时简单理解定义) • 静态变量在子程序,函数模块和静态方法中声明。 • 生命周期与声明的上下文相关联。 • 使用“CLASS-DATA"语句,可以在类中声明变...
ABAP程序中的系统字段只在极少需要控制系统行为的时候才能被重写。 System fields are filled by theABAP runtime environmentand can be used in an ABAP program to query system statuses. With one exception (sy-repid), system fields are variables, but they should only be accessed on a read-only basi...

ABAP system fields are always available in ABAP programs. The runtime system fills them according to context. They can then be used in programs to query the system status. System fields are variables but you should always treat them as though they were constants, and only read them. If you...
其中最常用的系统变量有:SY-SUBRC: 系统执行某指令后,表示执行成功与否的变量,’’ 表示成功SY-UNAME: 当前使用者登入SAP的USERNAME;SY-DATUM: 当前系统日期;SY-UZEIT: 当前系统时间;SY-TCODE: 当前执行程序的Transaction codeSY-REPID: ABAP 程式名，目前的主程式SY-CPROG: ABAP 程式名SY-SYSID: R/3 系統，...
Click tab “Source Code Extract”, and I know the system fails to allocate necessary memory for this CONCATENATE operation. I can not imagine how big the m_content or value could be. The information in “Chosen variables” could not help me too much: ...
Variables that you declare with the DATA statement live for as long as the context in which they are defined. Therefore variables in an ABAP main program exist for the entire runtime of the program, and local variables in procedures only exist for as long as the procedure is running....
Within ABAP, you have the option of referring to specific characters within a field. This is referred to as processingsubfields, whereby a specific character’s position within its field is referenced. Again, observe the code below: To start with, new DATA variables are declared, “int_telephon...
