[SAP]ABAP动态生成经典应用之Table数据Upload 程序

开发说明:在CBO的程序开发过程中,需要为Table准备大量的测试数据,手动录入效率低,不专业,我们可以采用其他的高级编辑工具(例如:EXCEL,EditPlus)按照Table数据存储结构准备好数据,最后保存为ASC的文本文件,通过执行下面开发的程序,下面的程序执行的功能就是把编辑好的文本文件上的数据上载到SAP对应的Table中,小程序非常实用,也适用于我们大量更新Table数据时使用,ABAPer们的手头必备啊!
 
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。
