Hi all After some trial and error I figured out, that this is an issue with Internet Explorer. With Firefox this works without problems, but with Internet Explorer you only can call the url with output set to pdf if the link is embedded in the webpage. As soon as the link is in the webpage it works and if you use the same link to enter it manually in the address are, well then the link does not work. I just embedd the link in webpages and the calls work (I am using Tibco GI). Kind Regards Bruno
