** In ABAP, if you assign a field symbol <fs1> to a field symbol <fs2>, <fs1> takes the value of the data object to which <fs2> refers (value semantics). ** Field symbols in ABAP are always dereferenced, that is, they always access the referenced data object. If you want to ch...

report z_xul_test2 中 定义了 全局变量 G_DATA1 , 分别调用了 z_xul_tes1 中的 form 和 function zbapi_test , 这两个调用都没有将 G_DATA1 作为参数,但在两个子程序中通过 field-symbol 成功修改了其值。 打印结果如下: 如果直接把 G_DATA1 作为一个普通变量来改,在语法检查时就通不过的,但如果...
SAP Managed Tags: ABAP Development Hello friend, Field Symbol is just like a pointer in C. Directly its having reference to address of the variable. We can use the field symbols mostely where we mostly need to update or append option to the data base. See the example code. <fs>-fie...
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to a field symbol before you...
in thedata areaof a program like with adata object. Instead, it works as a dynamic name of a memory area, where a specific data object or part of an object is located. A field symbol can be used instead of data objects at operand positions of statements. When a statement of this ...
The structured field symbol points initially to the work area wa specified after DEFAULT. The work area wa must be at least as long as the structure s. If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment ...
**Field symbols in ABAP are always dereferenced, that is, they always access the referenced data object. If you want to change the reference yourself in ABAP, you can use the ASSIGN statement to assign field symbol <fs1> to field symbol <fs2>....
