  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      retfield         = 'BANKN'

      dynprofield      = lv_fieldname
      value_org        = 'S'
      callback_program = sy-repid "必填,不然会报错
      callback_form    = 'FRM_CM_FORM_BANKN' "回调函数,主要是在这里面写
    TABLES
      value_tab        = lt_but0bk

    EXCEPTIONS
      parameter_error  = 1

  DATA: interface LIKE LINE OF shlp-interface.

"把其他想要赋值的屏幕字段加进interface表中,屏幕字段的属性必须是可编辑的,不可编辑的会赋值失败
  READ TABLE shlp-interface INTO interface INDEX 1.
