Elementary data types and reference types cannot be specified explicitly withVALUEfor constructing values, except when an initial value is created. Unlike when using the instance operatorNEW, the correct result
In each case,orefis assigned to the class reference variable that is reached first. Of course, aIS INSTANCE OFcheck would also be possible before the use of the casting operator?=. CLASS c1 DEFINITION. PUBLIC SECTION. DATA a1 TYPE string VALUE `C1`. ...
DATAminimum_valueTYPEIVALUE10. 在上面的代码段中,dl是C类型的变量,d2是dl类型的变量,minimum_value是 ABAP整数类型i的一个变量。 本章将解释ABAP中可用的各种变量类型。在ABAP-中有三种变数 1.静态变量 2.引用变数 3.系统变量 i.静态变量在子程序、函数模块和静态方法中声明。 2.生命周期与声明的上下文相关...
When you use NEW to create the Itab entries, you get the data reference back, where as when you use the VALUE operator, you get that data reference assigned to the variable on the left side. When using the NEW, the variable on the receiving side would be data reference TYPE REF TO ...

The syntax for declaring reference variables is −DATA <ref> TYPE REF TO <type> VALUE IS INITIAL. REF TO addition declares a reference variable ref. The specification after REF TO specifies the static type of the reference variable. The static type restricts the set of objects to which <...
value (empty FF value) must be avoided for any critical SAP system, as an excessive temp file during extraction could fill up the respective file system and can cause serious issues on the SAP system. Even for SAP development systems it is strongly recommended to override the default value. ...
