Hi,
Please use the following code,
DATA: ok_code TYPE sy-ucomm,
save_ok TYPE sy-ucomm,
lv_file(80),
lv_fieldln TYPE i,
lv_def_path TYPE rlgrap-filename,
lv_mode TYPE c VALUE 'S',
lv_tmp_filename TYPE rlgrap-filename,
lv_tmp_mask(80).
FIELD-SYMBOLS: <fs_tmp_sym>.
save_ok = ok_code.
CASE save_ok.
WHEN 'EXCEL'.
*--- On click of 'Download to Excel' button transfer the ALV data to
*--- Excel sheet.
lv_tmp_mask = ',.,..'.
lv_fieldln = strlen( lv_def_path ) - 1.
ASSIGN lv_def_path+lv_fieldln(1) TO <fs_tmp_sym>.
IF <fs_tmp_sym> = '/' OR <fs_tmp_sym> = '\'.
CLEAR <fs_tmp_sym>.
ENDIF.
*--- Get the file name & path to which file has to be downloaded.
CALL FUNCTION 'WS_FILENAME_GET'
EXPORTING
def_path = lv_def_path
mask = lv_tmp_mask
mode = lv_mode
IMPORTING
filename = lv_tmp_filename
EXCEPTIONS
inv_winsys = 1
no_batch = 2
selection_cancel = 3
selection_error = 4
OTHERS = 5.
IF sy-subrc = 0.
*--- As we need to download the file in 'XLS' format add the
*--- extension '.XLS' if it is not provided by the user.
IF NOT lv_tmp_filename CS c_excel.
CONCATENATE lv_tmp_filename c_excel INTO lv_file.
ELSE.
lv_file = lv_tmp_filename.
ENDIF.
ELSE.
EXIT.
ENDIF.
*--- Down load the file to the path and filename provided above.
CALL FUNCTION 'WS_DOWNLOAD'
EXPORTING
filename = lv_file
filetype = 'DAT'
TABLES
data_tab = gt_excel1
EXCEPTIONS
file_open_error = 1
file_write_error = 2
invalid_filesize = 3
invalid_type = 4
no_batch = 5
unknown_error = 6
invalid_table_width = 7
gui_refuse_filetransfer = 8
customer_error = 9
OTHERS = 10.
IF sy-subrc = 0.
MESSAGE i000(zf) WITH text-017.
ELSE.
MESSAGE e939(zf) WITH lv_file. "Errors while downloading.
ENDIF.
ENDCASE.
gt_excel1 is the internal table you provide to the FM for downloading.
lv_file is automatically taken care of from the input provided by the user.
The above code is triggered when a button in Application tool bar is clicked. Please use it as needed. It will ask for the path to which file has to be downloaded and once provided it will download the table only to excel.
It will work for sure.
Regards,
Paul.
