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...
SAPABAP-Variables 变量是用于在程序的分配内存区域内存储值的命名数据对象。顾名思义,使用者可以在 ABAP语句的说明下更改变量的内容。ABAP中的每个变量都有一个特定的类型,它决定了 变量内存的大小和布局;可存储在该内存中的值的范围;以及可应用于该变量的操作集。 必须先声明所有变量,然后才能使用它们。变数声明的...
