ABAP将内表数据写入到Excel模板

下载模板文件前获取一下文件的存放位置：

DATA gv_file TYPE rlgrap-filename.
PERFORM get_fullpath CHANGING gv_file.

FORM get_fullpath  CHANGING p_file.
  CALL FUNCTION 'TMP_GUI_BROWSE_FOR_FOLDER'
    EXPORTING
      window_title    = 'Select Save Path'
      initial_folder  = ''
    IMPORTING
      selected_folder = p_file
    EXCEPTIONS
      cntl_error      = 1
      OTHERS          = 2.
ENDFORM.                    " GET_FULLPATH

下载模板：

PERFORM download_temp USING 'ZPICKINGLIS'.

FORM download_temp  USING    value(p_name).
  DATA: l_objdata     LIKE wwwdatatab,
        l_objname     TYPE string,
        l_rc          LIKE sy-subrc,
        l_errtxt      TYPE string,
        l_objid       TYPE wwwdatatab-objid.

  l_objid = p_name.
  CONCATENATE l_objid '.XLSX' INTO l_objname.
  CONDENSE l_objname NO-GAPS.
  SELECT SINGLE relid objid
    INTO CORRESPONDING FIELDS OF l_objdata
    FROM wwwdata
    WHERE srtf2 = 0
    AND relid = 'MI'
    AND objid = l_objid.

  CALL FUNCTION 'DOWNLOAD_WEB_OBJECT'
    EXPORTING
      key         = l_objdata
      destination = gv_file
    IMPORTING
      rc          = l_rc.
  IF l_rc <> 0.
    CONCATENATE 'Template:' l_objname 'download failed' INTO l_errtxt.
    MESSAGE l_errtxt TYPE 'E'.
  ENDIF.
ENDFORM.                    " DOWNLOAD_TEMP

通过OLE方式将内表数据写入到模板文件中：

      gv_sheet       TYPE ole2_object,
      gv_cell        TYPE ole2_object,

  CONCATENATE gv_file '\' 'Picking Pallet List-' sy-datum sy-uzeit '.XLSX' INTO gv_file.
  l_visible = 'X'.
  CREATE OBJECT gv_application 'Excel.Application'.
  PERFORM open_excel_sheet USING l_visible gv_file 'Sheet1'.
  PERFORM fill_excel USING gv_application.
  PERFORM free_object.

    EXPORTING

  CALL METHOD OF gv_sheet 'Activate'.
  IF pv_visible = 'X'.
    SET PROPERTY OF gv_application 'Visible' = 1.
  ENDIF.
