ABAP Excel处理-内表导出为Excel文件
目录
一、概述
二、内表导出为Excel文件的实现
1. OLE下载内表数据为Excel文件
2. DOI下载内表数据为Excel文件
3. 生成文本形式的Excel（.xls或.csv）
4. 标准方法输出Excel文件流（用作接口或后台）
5. Transformation 生成xml格式的Excel(.XLS)
6. ABAP2XLSX 和 XLSX Workbench
三、总结
一、概述
SAP中Excel的处理，在项目需求中算是比较常见，内表数据生成Excel文件是其中一种，实现方式常见的有OLE,DOI和直接操作Excel文件（xml格式文件或者一般文本格式文件）；OLE和DOI使用方便，但是缺点是不能脱离gui使用；直接操作Excel文件方式适用性更强，常用在web端接口或者邮件发送，其中代表性的是ABAP2XLSX。
ABAP中标准下载内表数据为Excel文件的函数中，使用OLE实现的MS_EXCEL_OLE_STANDARD_DAT，使用DOI实现的SAP_CONVERT_TO_XLS_FORMAT/XXL_FULL_API，以及GUI_DOWNLOAD/CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD直接下载以tab为分隔符的文本形式的excel文件（.xls或者.csv文件）。
实际使用中，上述标准函数均差强人意，各有缺点，因此这里总结一些abap下载内表数据为Excel文件的示例代码，以供参考。
二、内表导出为Excel文件的实现

3. 生成文本形式的Excel（.xls或.csv）
字段数据拼接生成text文件，以tab为间隔的.xls文件，以’,‘为分割的.csv文件，这里以.xls文件为例。
参数为内表数据，下载地址全路径(Excel文件后缀为.xls)和Fieldcat。日期和数值格式可以根据情况做格式特殊处理。

ENDMETHOD. 5. Transformation 生成xml格式的Excel(.XLS)
将Excel模版文件另存为xml格式的Excel文件
新建transformation(xslt)，并将上述保存的xml文件内容复制到下图红框处
将xml文件中数据部分重新绑定数据源为transformation传入内表，生成对应xml文件，然后下载后缀为.xls的Excel文件。
如下附加对应transformation语法处理。
循环处理内表(TABLE为传入内表)
...... 数据据绑定(如果在循环内,父节点已声明路径,仅用字段绑定,已使用variable声明的同理)
分支
......
......
变量声明及使用
使用大括号表示使用值

6. ABAP2XLSX 和 XLSX Workbench
ABAP2XLSX 参考地址：abap2xlsx - ABAP Development - Community Wiki
Git包中有很多demo以供参考，算是目前功能最全的使用abap处理Excel的git源码，代码原理基于XLSX文件的结构，如下图XLSX文件是包含一些xml文件的压缩包。
因此ABAP2XLSX 处理Excel文件时由于版本的不同，可能会出现一些小bug，找到问题，调整对应xml文件的生成即可。
XLSX Workbench 参考地址：XLSX Workbench for SAP(ABAP) – tool for exporting data to Excel | SAP Blogs
图形化界面操作，较为友好。
三、总结
内表数据生成excel文件的需求中，如果不要求格式，直接下载内表为Excel表格，可以考虑使用标准类，相对更方便，使用也比较友好，既可以在gui端使用也可以在FPM等web端使用。如果带有较为复杂的格式，gui端建议使用DOI，提前上传模版到OAOR，然后填充数据，而且对比起OLE更加友好。如果是web端需求或者格式要求更复杂，建议使用ABAP2XLSX。
