Length of parameter field

Question

Hello all,
I'm having trouble with a parameter on a selection-screen. I have a field in which the user must enter a filename/path to a workstation file. The length of the parameter field is 128 (RLGRAP-FILENAME), but on the screen, the parameters appears only in length 45 scrollable. Since our users are using loooooong directory pathes, they would like to see the complete filepath/name without scrolling. Is there any possibility to show all 128 digits of the parameter on the screen without manually editing the selection screen?
Thank you for your help, kind regards, Kathrin!

You can use the object/method version of the file F4 help and there is one for directory and one for file name i think. directory_browse for the directory and FILE_OPEN_DIALOG
***************************directory
*Selecting a Directory
data: gd_path(500) type c.
parameters: p_path like rlgrap-filename.
at selection-screen on value-request for p_path.
    CALL METHOD cl_gui_frontend_services=>directory_browse
        EXPORTING window_title = 'File Directory'
                        initial_folder = 'C:'
        CHANGING selected_folder = gd_path.
    CALL METHOD cl_gui_cfw=>flush.
    concatenate gd_path '' into p_path.
file
*Selecting a File, plus inserting default file extension
tables rlgrap.
data: it_tab type filetable,
      gd_subrc type i.
select-options so_fpath for rlgrap-filename.
at selection-screen on value-request for so_fpath-low.
REFRESH: it_tab.
CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_OPEN_DIALOG
    EXPORTING
        WINDOW_TITLE = 'Select File'
        DEFAULT_FILENAME = '*.txt'
        MULTISELECTION = 'X'
    CHANGING
        FILE_TABLE = it_tab
        RC = gd_subrc.
loop at it_tab into so_fpath-low.
    so_fpath-sign = 'I'.
    so_fpath-option = 'EQ'.
    append so_fpath.
endloop.
Hope this helps
