Hi there,
On my SAP server, i have a directory created specifically to store input files generated from other external systems.
From my ABAP program, i need to check if any file exist on that application server directory. If yes, then i will proceed to read the input file and process it.
If it's empty, then output message that file is not available.
Are there any FM to do this?

you can use this code to do this...
Upload data from file
DATA: lv_filename TYPE string, "File name
lv_line TYPE string. "One line entry in a file
lv_filename = iv_file_name.
IF iv_location = gc_application.
IF iv_record_count IS SUPPLIED.
Open file
IF gv_file IS INITIAL.
OPEN DATASET lv_filename FOR INPUT IN TEXT MODE
ENCODING DEFAULT
IGNORING CONVERSION ERRORS.
IF sy-subrc <> 0.
RAISE file_open_error.
ENDIF.
gv_file = gc_check.
ENDIF.
Read data
DO iv_record_count TIMES.
READ DATASET lv_filename INTO lv_line.
IF sy-subrc <> 0.
Close file
CLOSE DATASET lv_filename.
IF sy-subrc NE 0.
RAISE file_close_error.
ENDIF.
CLEAR gv_file.
Exit from the loop
EXIT.
ENDIF.
IF iv_separator IS NOT INITIAL.
CALL FUNCTION 'Z_WM_SPLIT_DATA'
EXPORTING
iv_data = lv_line
iv_separator = iv_separator
CHANGING
ct_tab_data = ct_tab_data.
ELSE.
CHECK NOT lv_line IS INITIAL.
APPEND lv_line TO ct_tab_data .
ENDIF.
ENDDO.
ELSE.
Open file
OPEN DATASET lv_filename FOR INPUT IN TEXT MODE
ENCODING DEFAULT
IGNORING CONVERSION ERRORS.
IF sy-subrc <> 0.
RAISE file_open_error.
ENDIF.
Read data
DO.
READ DATASET lv_filename INTO lv_line.
IF sy-subrc <> 0.
EXIT.
ENDIF.
IF iv_separator IS NOT INITIAL.
CALL FUNCTION 'Z_WM_SPLIT_DATA'
EXPORTING
iv_data = lv_line
iv_separator = iv_separator
CHANGING
ct_tab_data = ct_tab_data.
ELSE.
CHECK NOT lv_line IS INITIAL.
APPEND lv_line TO ct_tab_data .
ENDIF.
ENDDO.
Close file
CLOSE DATASET lv_filename.
IF sy-subrc NE 0.
RAISE file_close_error.
ENDIF.
ENDIF.
