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...
SAP支持的动态时间计算选择如下: B类型选择变量:用户变量 (User-specific Selection Variables) 最后来看下用户变量,用户变量是与用户ID绑定的选择变量,如果我们要在变式中使用用户变量,需要满足3个条件: No.1 该屏幕字段用到了MEMORY ID语法关联到了PID; No.2 表TUVID 中有相应的PID值; No.3 已经维护了相应的...
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 the ABAP runtime environment and 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 ...
