上载CSV文件到本机(KCD_CSV_FILE_TO_INTERN_CONVERT)

可以通过过函数KCD_CSV_FILE_TO_INTERN_CONVERT将CSV格式的文件上载到本机。

代码如下：

REPORT z_upload_csv.
TYPE-POOLS: kcde.

TYPES: BEGIN OF ty_input,
         id    TYPE string,
         name  TYPE string,
         place TYPE string,
         phone TYPE string,
       END OF ty_input.

CONSTANTS: c_separator TYPE c VALUE ‘,‘.

DATA: gt_intern  TYPE kcde_intern,
      gwa_intern TYPE kcde_intern_struc.

DATA: gt_input  TYPE TABLE OF ty_input,
      gwa_input TYPE ty_input.

*F4 help for the file in selection screen
  CALL FUNCTION ‘F4_FILENAME‘
    IMPORTING
      file_name = p_file.

* Read data from File
  PERFORM readfile USING p_file.
* Display data
  PERFORM display.
*&---------------------------------------------------------------------*

*&---------------------------------------------------------------------*
FORM readfile USING p_file TYPE localfile.

  DATA: lv_filename TYPE rlgrap-filename.
  DATA: lv_index TYPE i.
  FIELD-SYMBOLS: <lfs_field> TYPE any.

  lv_filename = p_file.

* 读取CSV文件
  CALL FUNCTION ‘KCD_CSV_FILE_TO_INTERN_CONVERT‘
    EXPORTING
      i_filename      = lv_filename
      i_separator     = c_separator
    TABLES
      e_intern        = gt_intern
    EXCEPTIONS
      upload_csv      = 1
      upload_filetype = 2
      OTHERS          = 3.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

* 将读取的CSV内容转换保存到内表gt_input中
  LOOP AT gt_intern INTO gwa_intern.
    MOVE : gwa_intern-col TO lv_index.
    ASSIGN COMPONENT lv_index OF STRUCTURE gwa_input TO <lfs_field>.
    MOVE : gwa_intern-value TO <lfs_field> .
    AT END OF row.
      APPEND gwa_input TO gt_input.
      CLEAR gwa_input.
    ENDAT.
  ENDLOOP.

ENDFORM.                    " READFILE
*&---------------------------------------------------------------------*
*&      Form  DISPLAY
*&---------------------------------------------------------------------*
FORM display.
* 输出CSV内容
  LOOP AT gt_input INTO gwa_input.
    WRITE:/ gwa_input-id,8 gwa_input-name,16
            gwa_input-place,26 gwa_input-phone.
  ENDLOOP.
ENDFORM.                    " DISPLAY
