ABAP FIELDS

在 ABAP 中,FIELDS 通常用于定义结构体或数据表的字段。FIELDS 语句的语法如下:
```
FIELDS <字段名1> TYPE <数据类型1> [LENGTH <长度>] [DECIMALS <小数位数>]
<字段名2> TYPE <数据类型2> [LENGTH <长度>] [DECIMALS <小数位数>]
...
```
其中,`<字段名>` 是字段的名称,`<数据类型>` 是字段的数据类型,`<长度>` 是字段的长度(可选),`<小数位数>` 是字段的小数位数(可选)。
例如,下面的代码定义了一个名为 `ls_person` 的结构体,包含三个字段:`first_name`、`last_name` 和 `age`。
```
DATA: BEGIN OF ls_person,
first_name TYPE string,
last_name TYPE string,
age TYPE i,
END OF ls_person.
```
在这个例子中,`FIELDS` 关键字被省略了,因为它在 `BEGIN OF` 语句中隐式地指定了。在实际编程中,你可以使用 `FIELDS` 语句来定义结构体或数据表的字段,以便更好地组织和管理数据。
