首先把代码贴出来:

REPORT ZTMP_TEST_IT003.

*功能码返回值
DATA:OK_CODE TYPE SY-UCOMM,
     SAVE_OK TYPE SY-UCOMM.

DATA:FIELD_NAME  TYPE char8,
     FIELD_VALUE TYPE char8.

START-OF-SELECTION.

 CALL SCREEN 100.



MODULE status_0100 OUTPUT.
* SET PF-STATUS ‘xxxxxxxx‘.
* SET TITLEBAR ‘xxx‘.
ENDMODULE.

MODULE user_command_0100 INPUT.
  SAVE_OK = OK_CODE.
  CLEAR OK_CODE.
*分析功能码，如果是工具条上的第2个按钮，则退出当前屏幕
  CASE SAVE_OK.
    WHEN ‘BACK‘.
      LEAVE PROGRAM.
  ENDCASE.
ENDMODULE.

MODULE pbo_0100_fields_setinfo OUTPUT.

*修改输出前屏幕上的数据
  FIELD_NAME  = SY-STEPL.
  CONDENSE FIELD_NAME NO-GAPS.
  CONCATENATE ‘Name：‘ FIELD_NAME INTO FIELD_NAME.
  CONDENSE FIELD_NAME NO-GAPS.
  FIELD_VALUE = SY-STEPL.

  LOOP AT SCREEN.
    IF screen-name = ‘FIELD_VALUE‘.
       screen-input = 0.
    ENDIF.
    MODIFY SCREEN.
  ENDLOOP.

ENDMODULE.

MODULE pbo_0100_fields_getinfo INPUT.
*获取屏幕数据
  DATA:t_value TYPE char8.
  CLEAR t_value.
  t_value = FIELD_VALUE.
ENDMODULE.
