批量更新数据表

此程序可以根据输入的表名，生成对表操作的ABAP源程序，然后系统运行产生的源程序，会让你选择要导入文件。文件要符合表的结构。
批量更新数据表，可以用于批量导入，准备数据可以用EXCEL，sql server，准备数据并导出成文本文件。

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
CODE：

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。

 

程序代码：如下

REPORT z_cbo_abap_01 NO STANDARD PAGE HEADING.

 

TABLES : dd03l,dd02t."表和列

 

DATA: BEGIN OF tab OCCURS 10,
        fcode(4),
      END OF tab.
DATA : BEGIN OF itab OCCURS 0,
        chk(1) TYPE c,                     " check box
        tabname    LIKE dd03l-tabname,     " Table name
        fieldname  LIKE dd03l-fieldname,   " Feld Name
        position   LIKE dd03l-position,    " Table
        keyflag    LIKE dd03l-keyflag,     " Primary Key
        datatype   LIKE dd03l-datatype,    " Data Type
        intlen     LIKE dd03l-leng,
       END OF itab.
DATA itab1 LIKE itab OCCURS 0 WITH HEADER LINE.
DATA : BEGIN OF uptab OCCURS 0,
        text(100) TYPE c,
       END OF uptab.
DATA: BEGIN OF error_message,
        line1(72),
        line2(72),
        line3(72),
      END OF error_message.
DATA : cnt1(8) TYPE c,
       fcode LIKE sy-ucomm,
       changed LIKE s38e-buf_varied,
       prog(8) TYPE c,
       msg(120) TYPE c,
       er_include LIKE sy-repid,
       er_line    LIKE sy-index,
       er_off     LIKE sy-tabix,
       er_subrc   LIKE sy-subrc.

1.程序初始界面，输入Upload的table名.

 

 

2.程序运行第一界面，显示程序自动生成的上载程序代码

 

3.程序运行第二界面，确认程序自动生成的上载程序代码，执行

 

4.程序运行第三界面中小界面，程序执行提示输入上在数据具体路径

 

4.OK,数据上载成功

 

补充1：上载数据文件格式，*.TXT DAT格式文件，俗称纯文本文件

 

补充2：SAP Table格式，注意不要理会Mandt Client字段，其他字段数据对应
