开发技术：
1.文本文件上载技术
2.动态程序代码生成技术
3.ABAP动态程序执行技术
4.TXT文本文件对应用Table字段编辑技术
注意事项：
文件文件编辑过程中时间日期格式为
20060201 120000 表示 2006.02.01 12：00：00
文本文件中不能包含除字符，数字之外的其他特殊符号。假如Table中对应的字段数据为空时，在编辑数据时也对应该列为空。
EXCEL
文件必须带表头。（不带表头的可以修改下程序）
代码如下：
TABLES : dd03l,dd02t.
*------------------------------------------------------------*
* 内表
*-----------------------------------------------------------------*
DATA: BEGIN OF tab OCCURS 10,
fcode(4),
