cl_gui_frontend_services=>file_save_dialog doesn't work for FIORI app

[dubbaka]

Hello Experts,

I have using cl_gui_frontend_services=>file_save_dialog to select Desktop path where my file would be saved. It works fine with GUI, but when we assign T-code to Fiori app it behaves different.

In Fiori app it does not Desk top path to save the file.

DATA: filename1 TYPE string,
lv_path TYPE string .

lv_path = 'C:\Documents and Settings\Desktop\'.

CALL METHOD cl_gui_frontend_services=>file_save_dialog
EXPORTING
window_title = 'Select File'
default_file_name = '.csv'
CHANGING
filename = filename1
path = lv_path
fullpath = filename.

IN GUI---->

In FIORI app it shows below popup ---->

How to avoid this Dialog ? the file gets downloaded in some path like Z:\filename... it doesn't show Desktop to select, please let me know if anyone knows any solution for this issue

I can use CALL FUNCTION 'F4_FILENAME', but using this function module in GUI I am able to select path and add my folder name as shown below. and File will get save in give folder.

If I perform same action in FIORI app it throw's an error stating that Test file does not exists as we have assigned Custom T-code to FIORI app will not behave same as GUI ?

Is there any way to get DESKTOP path from FIORI app and download the file at selected path.

I can not use ODATA Services because we not have License

Please help me if anyone have solution for this.
