Open dialog box in application server.

Question

hai frnds,
i am using the following FM for open dialog box in application.
  CALL FUNCTION 'F4_DXFILENAME_TOPRECURSION'
    EXPORTING
      i_location_flag = 'A'
      i_server = '?'
      i_path = f_app
      filemask = c_fnh_mask
       FILEOPERATION = 'R'
    IMPORTING
    O_LOCATION_FLAG = 'P'
    O_SERVER = '?'
      o_path = f_app
    ABEND_FLAG =
    EXCEPTIONS
      rfc_error = 1
      OTHERS = 2.
the path is been copied to the input box but when i am trying to open the file selected it is not retrieving the data and also the given path is changed to upper case. i had tried to change it in start of selection. but the same is hapenning. also my client requested some of the following...
1) the dialog should open at '//sapglobal_users'
2) the files should be sorted in desc group by date and time of creation.
3) the full path name should be visible in the dialog box which is not hapenning (i.e., if the path is > the visible length the invisible part is truncated. This shd not happen.)

DO THIS..
parameters: file(128) obligatory  lower case.
DATA: c_fnh_mask TYPE dxfields-filemask VALUE '*',
      searched_dir TYPE dxfields-longpath,
AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE.
  if loc1 = space.
     message e307 with 'Enter Directory To Pick Up File'.
  endif.
searched_dir = XXX. " WRITE THE DIRECTORY NAME--LIKE 'E:\usr\sap\put'.
  TRANSLATE searched_dir TO LOWER CASE .
  CALL FUNCTION 'F4_DXFILENAME_TOPRECURSION'
    EXPORTING
      i_location_flag = 'A'
      i_server = ' '
      i_path = searched_dir
      filemask = c_fnh_mask
    FILEOPERATION = 'R'
   IMPORTING
    O_LOCATION_FLAG =
    O_SERVER =
      o_path = file_path
    ABEND_FLAG =
   EXCEPTIONS
        rfc_error = 1
        OTHERS = 2.
