ENDFORM.   

使用的时候用

at selection-screen on value-request for p_file.

  perform zfrom_get_filename changing p_file.

at selection-screen on p_file.

或者

at selection-screen on value-request for p_file.

perform f4_filename changing p_file.

at selection-screen on p_file.

都行，也可以用F4直接打开，主要是用在

at selection-screen on value-request for p_file.

  perform zfrom_get_filename changing p_file.

at selection-screen on p_file.

这个位置就行

另外下载的时候，也可以用这两个去确定地址
