Hi Onur,
When reviewing the browser developer tools in IE, do you see if the PDF data is loaded correctly?
in you gateway implementation, did you add the HTTP response header content-disposition?
data: ls_header type ihttpnvp.
ls_header-name = 'content-disposition'.
ls_header-value = 'inline;filename=file.pdf'.
set_header( ls_header ).
Best regards,
Maarten
