SWM0-Excel模板上载以及模板下载程序

SAP系统中用Excel上载数据时，为防止用户用错模板，可以将excel模板保存在SMW0中，每次上载前通过程序再从SMW0下载下来。

1, SMW0 模板上载

Tcode SMW0选择‘Binary data...\'选项

&lt;img class="alignnone size-full wp-image-3261" src="http://www.baidusap.com/wp-content/uploads/2017-02-28_13-30-13.png" alt="2017-02-28_13-30-13" width="573" height="225" /&gt;

输入package，运行

&lt;img class="alignnone size-full wp-image-3262" src="http://www.baidusap.com/wp-content/uploads/2017-02-28_13-31-13.png" alt="2017-02-28_13-31-13" width="691" height="210" /&gt;

进入下一屏后，点击创建按钮添加excel文档，

&lt;img class="alignnone size-full wp-image-3263" src="http://www.baidusap.com/wp-content/uploads/2017-02-28_13-31-45.png" alt="2017-02-28_13-31-45" width="769" height="398" srcset="http://www.baidusap.com/wp-content/uploads/2017-02-28_13-31-45.png 769w, http://www.baidusap.com/wp-content/uploads/2017-02-28_13-31-45-740x383.png 740w, http://www.baidusap.com/wp-content/uploads/2017-02-28_13-31-45-768x397.png 768w" sizes="(max-width: 769px) 100vw, 769px" /&gt;

如果出现下面的错误，提示’No MIME type assigned to object\'，则需要为excel格式的文件创建一个类型，

&lt;img class="alignnone size-full wp-image-3264" src="http://www.baidusap.com/wp-content/uploads/2017-02-28_13-32-29.png" alt="2017-02-28_13-32-29" width="506" height="178" /&gt;

MIME type创建通过菜单

&lt;img class="alignnone size-full wp-image-3265" src="http://www.baidusap.com/wp-content/uploads/2017-02-28_18-18-42.png" alt="2017-02-28_18-18-42" width="553" height="247" /&gt;

点击新建按钮，输入type和扩展名(extension)，保存即可。如下图，type是excel，扩展名是*.xls

&lt;img class="alignnone size-full wp-image-3266" src="http://www.baidusap.com/wp-content/uploads/2017-02-28_18-19-39.png" alt="2017-02-28_18-19-39" width="386" height="235" /&gt;

2, 模板下载代码

下载主要通过函数DOWNLOAD_WEB_OBJECT()实现。

代码如下：

REPORT ZTEST_SMW0_DOWNLOAD.

DATA: lwa_wwwdata_tab LIKE wwwdatatab,
      l_filename      TYPE rlgrap-filename.

 l_filename = \'C:/temp/xx.xlsx\'.
 SELECT SINGLE *
   FROM wwwdata
  INNER JOIN tadir
     ON wwwdata~objid = tadir~obj_name
   INTO CORRESPONDING FIELDS OF lwa_wwwdata_tab
  WHERE wwwdata~srtf2  = 0
    AND wwwdata~relid  = \'MI\'             "标识二进制的对象
    AND tadir~pgmid    = \'R3TR\'
    AND tadir~object   = \'W3MI\'
    AND tadir~obj_name = \'ZGA_NONSTPRICE\'."模板名字

  IF sy-subrc = 0.
    CALL FUNCTION \'DOWNLOAD_WEB_OBJECT\'
      EXPORTING
        key         = lwa_wwwdata_tab
        destination = l_filename.
  ENDIF.

SWM0中内容：

&lt;img class="alignnone size-full wp-image-3269" src="http://www.baidusap.com/wp-content/uploads/2017-02-28_18-47-36.png" alt="2017-02-28_18-47-36" width="788" height="237" srcset="http://www.baidusap.com/wp-content/uploads/2017-02-28_18-47-36.png 788w, http://www.baidusap.com/wp-content/uploads/2017-02-28_18-47-36-740x223.png 740w, http://www.baidusap.com/wp-content/uploads/2017-02-28_18-47-36-768x231.png 768w" sizes="(max-width: 788px) 100vw, 788px" /&gt;

如果要通过程序上载模板文件到SMW0中，可以用函数UPLOAD_WEB_OBJECT()实现。

以上。
