因为"DATA itab TYPE line OCCURS 0 WITH HEADER LINE."这样的声明, 已经隐式声明了一个与内表同名的header line. 所以OCCURS用来声明内表可能造成二义性(ambiguous). 于是,OCCURS被认为是old的东西,采用一下方式声明一个内表比较好: DATA itab TYPE STANDARD TABLE OF line. 还有一种声明内表的方法: DATA:...

line是一个class,而wa是一个object. 接着是声明一个每一行的类型是line的internal table: DATA itab TYPE line OCCURS 0. 我在暂时把OCCURS作为了区别工作区和内表的标志. OCCURS应该有更深层次的意义,但我目前只能领悟至此... 当我们用以上这个方法来声明一个iternal table时,可以选择是否有无header line. ...

1、ABAP 内表(internal table) 标题行(header line) 工作区(work area) 简介 - SAP先是用TYPES关键字定义一个行(row)的类型.如下:TYPES: BEGIN OF line, field1 TYPE i, field2 TYPE i,END OF line.这里的line,就相当于一个自定义的类型,表示一行(row)的字段(field).这里一行有两个字段field1和field...
The work area has the same data type as internal table declaration. Work area is called as HEADER line. The data automatically places to work area if any read operations performed on internal table. The data loaded from work area if any insertion or modify operations performed on internal tabl...
对于没有HEADER LINE的内表,只能通表外部WORK AREA来传递数据,如下所示: TABLES:USER21. DATA:BEGIN OF EMPTAB, NAME LIKE USER21-BNAME, TELNUM LIKE USER21-PERSNUMBER, ADDR LIKE USER21-ADDRNUMBER, END OF TMPTAB. DATA:EMP LIKE STANDART TABLE OF EMPTAB. ...
This data object is known as the header line of the internal table. You use it as a work area when working with the internal table (see Using the Header Line as a Work Area). When you use internal tables with header lines, you must remember that the header line and the body of the...

1.使用occurs 0,定义的不再是对象,而是internal table 2.使用with header line后缀,定义为internal table的同时也定义了一个同名对象,因此可以用以下语句: LOOP AT STH. WRITE: / STH. ENDLOOP. 3.TYPE后面接结构,LIKE后面接对象 4.OBLIGATORY为必输字段 ...
