EXCEL常见操作笔记 1

1.    Excel模板下载

TCODE:SMW0

创建excel模板(其他模板也可以)

我们选择二进制数据

选择在哪个包里面创建模板

 

点击创建：

备注：如果出现以下错误( 无分配给对象 c:\ 的 MINE类型)

 则需要进行以下操作：保存。

 

 

 

 这样就可以成功创建了。

在report程序中代码：

TABLES:sscrfields.

SELECTION-SCREEN: FUNCTION KEY 1."在标题行
SELECTION-SCREEN PUSHBUTTON 02(10) TEXT-001 USER-COMMAND pb1."在select界面

INITIALIZATION.
  sscrfields-functxt_01 = '下载模板'.

AT SELECTION-SCREEN.
  CASE sscrfields-ucomm.
    WHEN 'FC01' OR 'PB1'.

CALL METHOD zcl_document_jxzhu=>download_template_to_frontend
        EXPORTING
          name_of_template = '物料主数据客制表'
*         iv_relid         = 'MI'
          iv_objid         = 'ZMMT001'
*        IMPORTING
*         rv_filepath      =
        EXCEPTIONS
          download_error   = 1
          OTHERS = 2.
      IF sy-subrc <> 0.
*       Implement suitable error handling here
      ENDIF.
    WHEN OTHERS.
  ENDCASE.

其中zcl_document_jxzhu=>download_template_to_frontend的代码为：

同学们可以直接创建SE24类。方便以后可以直接调用。
