结合上传路径添加的搜索帮助

  PERFORM EXCEL_PATH.```
```FORM EXCEL_PATH .
    CALL FUNCTION 'TB_LIMIT_WS_FILENAME_GET'
    IMPORTING
      FILENAME               = P_PATH
    EXCEPTIONS
     SELECTION_CANCEL       = 1
     SELECTION_ERROR        = 2
     OTHERS                 = 3
ENDFORM.   ```

* 拓展
根据单选按钮判断要不要显示上传路径
```SELECTION-SCREEN: BEGIN OF BLOCK blk3 WITH FRAME TITLE text-003.
PARAMETERS:  R1  RADIOBUTTON GROUP BUT USER-COMMAND SEL DEFAULT 'X',  "上传数据
R2  RADIOBUTTON GROUP BUT .             "查询数据
SELECTION-SCREEN: END OF BLOCK blk3.```


```SELECTION-SCREEN: BEGIN OF BLOCK blk5 WITH FRAME TITLE text-005.
 PARAMETERS: P_PATH LIKE RLGRAP-FILENAME MODIF ID m1.               "选择路径 并隐藏响应
SELECTION-SCREEN: END OF BLOCK blk5.```
***********
``` LOOP AT SCREEN.
    IF screen-group1 = 'M1' OR screen-group1 = 'M2'.
*上传文件显示
      IF r2 = 'X'.
        screen-active = 0.
      ENDIF.
*下载/日志隐藏
      IF r1 = 'X' AND screen-group1 = 'M2'."这个if永远不满足，所以不会执行
        screen-active = 0.
      ENDIF.
  MODIFY SCREEN.
  ENDIF.
  ENDLOOP.```

给选择屏幕加按钮
```DATA gs_funx TYPE smp_dyntxt.      "选择屏幕按钮```

```SELECTION-SCREEN:FUNCTION KEY 1.
INITIALIZATION. "初始化选择屏幕
gs_funx-icon_id   = icon_export  . "按钮图标
gs_funx-icon_text = '下载模板'.
sscrfields-functxt_01 = gs_funx.```
