check the method <b>FILE_EXIST</b> of the class <b>CL_GUI_FRONTEND_SERVICES</b>. It checks the existence of the file in the frontend, hope this helps.

Hi,

Check this

IF p_file NP '*.xls'.

MESSAGE e000 WITH text-t07.

ENDIF.

You can also use F4_FILENAME to get a popup when f4 is pressed

Hi Neha,

You can write simple code in AT SELECTION-SCREEN event by giving the special charators. I hope try it.

Reward if useful.

Hi Neha.

You can use SF_SPECIALCHAR_DELETE function.

CALL FUNCTION 'SF_SPECIALCHAR_DELETE'

EXPORTING

with_specialchar = in_file_name

IMPORTING

WITHOUT_SPECIALCHAR = out_file_name

• EXCEPTIONS

• RESULT_WORD_EMPTY = 1

• OTHERS = 2

.

IF in_file_name <> out_file_name.

There is special characters in the file name.

endif.

Regards.

Use this function to allow user to select a file name from the system.

Consider p_file is the name of the parameter.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_file.

CALL FUNCTION 'WS_FILENAME_GET'

EXPORTING

def_filename = space

def_path = space

mask = ',.,..'

mode = space

title = space

IMPORTING

filename = p_file

EXCEPTIONS

inv_winsys = 1

no_batch = 2

selection_cancel = 3

selection_error = 4

OTHERS = 5.
