Field symbols in ABAP are similar to pointers in other programming languages. However, pointers (as used in PASCAL or C) differ from ABAP field symbols in their reference syntax. The statement ASSIGN f to <fs> assigns the field f to field symbol <fs>. The field symbol <fs> then "points...
在abap里面,fieldsymbol就相当于c语言的指针。如果你定义并且分配了相应的结构或者变量给它,其实它就指向这个结构或者变量的地址,如果修改了fieldsymbol的值,则相应结构或者变量的值也随之更改。 2.如何定义指针: 基本形式:field-symbols. 附加信息: 1...type:定义一个数据类型,然后定义指针 2...typerefto:指针指...

SAP Managed Tags: ABAP Development hi Rahul, you have to assign the field as well to another field symbol: DATA : <fs_field> TYPE ANY. loop at <fs_alv_histd> assigning <fs_wa>. ASSIGN COMPONENT 'OIL_DISP' OF STRUCTURE <fs_wa> TO <fs_field>. if <fs_field> = 0 . ==> cod...
ITAB是原始数据表 ITAB2是中转表 ITAB3是最后结果表 DATA: BEGIN OF ITAB OCCURS 0,COL1 TYPE I,COL2 TYPE I,COL3 TYPE I,FLAG TYPE CHAR1,END OF ITAB.ITAB-COL1 = 1.ITAB-COL2 = 2 .ITAB-COL3 = 3.APPEND ITAB.ITAB-COL1 = 1.ITAB-COL2 = 2 .ITAB-COL3 = 4.AP...
1、ST05是用于在开发ABAP程序时,对应事务码取得的字段是“数据结构”而不是“透明表”的时候,通过ST05 的“SQL跟踪”来获得相关“Select”的语句;一般查看“REC”列耗时比较多的“Select”语句; 2、跟踪时如果有涉及到“数量”这类有对数据表进行更新或插入操作的,则直接去查Update和Insert的SQL语句; ...

SAP Managed Tags: ABAP Development Hi, Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned ...

SAP 方法/步骤 1 像图中显示的那样，假设前面的订单编号、发货单、物料凭证编号、发货过账日期、物料代码、物料描述、业务员都相同，只有数量、金额不同 2 先定义表结构，一定要将数量、金额放到最后定义，这样是为了方便后面使用AT END OF 最后字段X.3 在ABAP开发过程中，将查询出的所有数据放到临时表 lt_msegc...
