SAP将指定EXCEL工作SHEET的数据上传到内表
本文描述了一个SAP ABAP类方法
upload_excel_2internaltab，用于将Excel文件数据上传到内部表。主要功能包括：
- 验证Excel行列范围有效性，若起始值大于结束值则抛出异常
- 检查文件是否存在，支持直接指定路径或通过文件对话框选择
- 使用OLE自动化技术操作Excel，包括打开工作簿、选择工作表、复制指定单元格范围数据
- 通过剪贴板将Excel数据导入ABAP内部表，调用标准函数进行格式转换
- 包含完善的异常处理机制，针对文件不存在、操作失败等情况抛出定制异常类ZCX_AB_K2_SERVICE的相应错误
- 最后释放所有OLE对象以关闭Excel进程
该方法实现了Excel与SAP系统间的数据交互，适用于需要批量导入数据的业务场景。
