ABAP BDC MM02实例
来源：互联网 发布：数据库删除多条数据 编辑：程序博客网 时间：2024/06/15 19:46
该实例整合了下载模板功能，可以下载模板，按照模板格式填写excel数据，然后根据这些数据修改物料信息。实际做的时候先录屏，然后才能得出模板的。
效果：
大体步骤：
1.shdb录屏
2.程序实现
上传路径（绘制屏幕）
上传文件
批导实现
反馈结果处理（显示）
录屏就省略了，得到程序代码后，我们只要数据结构定义和 perform bdc_dynpro ，perform bdc_field这两部分内容。即：
---------------------------------------------------------------------------------
根据自动生成的record结构，可以自己制作模板：
