BDC批量修改物料描述

一、定义变量

type-POOLs:TRUXS,slis.

TYPES: BEGIN OF ty_input ,
        matnr  TYPE  mara-matnr ,  " 物料号
        maktx  TYPE  makt-maktx,"物料描述
      END OF ty_input .

DATA: gt_input TYPE STANDARD TABLE OF ty_input.
FIELD-SYMBOLS: <gs_input> TYPE ty_input.
DATA: gt_bdcdata TYPE STANDARD TABLE OF bdcdata,"bdc
      gt_msg TYPE STANDARD TABLE OF bdcmsgcoll,"消息
      gs_msg TYPE bdcmsgcoll."消息

TYPES: BEGIN OF ty_message ,
        matnr  TYPE  mara-matnr ,  " 物料号
        maktx TYPE makt-maktx, "描述
        msg    TYPE  string ,
      END OF ty_message .

DATA: gt_message TYPE STANDARD TABLE OF ty_message,
      gs_message TYPE ty_message.
*alv
DATA: gt_fieldcat TYPE slis_t_fieldcat_alv.
DATA: gs_fieldcat TYPE LINE OF slis_t_fieldcat_alv.
DATA: gs_layout TYPE slis_layout_alv.

二、屏幕元素

SELECTION-SCREEN BEGIN OF BLOCK bk1 WITH FRAME TITLE text-.      "选择文件路径
PARAMETERS: p_ufile LIKE rlgrap-filename OBLIGATORY MEMORY ID p_ufile.
SELECTION-SCREEN END OF BLOCK bk1.

三、调用代码

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_ufile.
  PERFORM get_filepath.

START-OF-SELECTION.

  PERFORM upload_data. "上载文本资料

  PERFORM f_bdc.

END-OF-SELECTION.

  PERFORM f_alv_fieldcat.
  PERFORM f_layout.
  PERFORM f_display.

四、调用的form

  ENDIF.
