F4 help for a selection screen parameter with filename created dynamically

Former Member — Wed, 26 Nov 2008 14:37:25 GMT

Hi All,

I have a requirement where in an F4 help should be present for a selection screen parameter. After selecting the filepath and clicking OK button on the Dialog, the filename should be dynamically get created in the selection screen parameter field. For example:

if the path is D:\DOCS then at the end of DOCS the filename should automatically get populated.

Like below string:

D:\DOCS\new.txt

Is there any function module or method which does this kind of activity.

Thanks in advance,

Deepak

DATA : v_path1 TYPE string.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_path.
CALL METHOD CL_GUI_FRONTEND_SERVICES=>DIRECTORY_BROWSE
*  EXPORTING

CONSTANTS : lc_fname TYPE string VALUE 'ZRPP4000.XLS',

lc_fpath TYPE string VALUE 'C:\',

lc_extn TYPE string VALUE 'XLS'.

CALL METHOD cl_gui_frontend_services=>file_open_dialog

EXPORTING

default_filename = lc_fname

initial_directory = lc_fpath

default_extension = lc_extn

CHANGING

file_table = li_filetable

rc = lv_rc

EXCEPTIONS

file_open_dialog_failed = 1

cntl_error = 2

error_no_gui = 3

not_supported_by_gui = 4

OTHERS = 5.

IF sy-subrc = 0 .

READ TABLE li_filetable INTO lv_filename INDEX 1.

IF sy-subrc = 0.

p_filename = lv_filename.

ENDIF.

REFRESH li_filetable.

CLEAR:lv_filename.

ENDFORM. "get_filename

" p_filename is selection screen parameter
