常用的模板一般是SMW0和OAOR，根据不同需求来的。

WAD有个不好的地方就是不支持GUI上的OLE和DOI，所以需要做转换，下面是常用的方式：

FUNCTION ZCRM_DOWNLOAD_TEMPLATE*"----------------------------------------------------------------------*"*"Local Interface:*"  IMPORTING*"     REFERENCE(IV_OBJID) TYPE  W3OBJID*"----------------------------------------------------------------------  DATA:    LS_FILEKEY TYPE          WWWDATATAB,    LT_MIME    TYPE TABLE OF W3MIME.  DATA:    LV_XSTRING          TYPE XSTRING,    LV_FILENAME         TYPE STRING,    LV_MIME_TYPE        TYPE STRING.  LS_FILEKEY-RELID = 'MI'.  LS_FILEKEY-OBJID = IV_OBJID.  CALL FUNCTION 'WWWDATA_IMPORT'    EXPORTING      KEY    = LS_FILEKEY    TABLES      MIME   = LT_MIME    EXCEPTIONS      OTHERS = 1.  IF sy-subrc <> 0.    RETURN.  ENDIF.  CALL METHOD CL_BCS_CONVERT=>SOLIX_TO_XSTRING    EXPORTING      IT_SOLIX   = LT_MIME*     IV_SIZE    =    RECEIVING      EV_XSTRING = LV_XSTRING.  SELECT SINGLE VALUE INTO LV_MIME_TYPE    FROM WWWPARAMS    WHERE RELID = LS_FILEKEY-RELID    AND OBJID = LS_FILEKEY-OBJID    AND NAME = 'fileextension'.  SELECT SINGLE VALUE INTO LV_FILENAME    FROM WWWPARAMS    WHERE RELID = LS_FILEKEY-RELID    AND OBJID = LS_FILEKEY-OBJID    AND NAME = 'filename'.  CL_WD_RUNTIME_SERVICES=>ATTACH_FILE_TO_RESPONSE(    EXPORTING      I_FILENAME      = LV_FILENAME      I_CONTENT       = LV_XSTRING      I_MIME_TYPE     = LV_MIME_TYPE      I_IN_NEW_WINDOW = ABAP_FALSE      I_INPLACE       = ABAP_FALSE ).ENDFUNCTION.

后来做FTP的时候就想到了另一个办法：

文件上传下载类型的模板。。。
