Without the SSO token in the URL you will be asked to login in anyway so it is just workspace/index.jsp
You could add ?multi_process=true if you wanted to open it in a new tab.
In fact, I want to open the HFM app as a workspace tab and not browser tab. I have updated my first post with a screenshot of what I wanto to achieve.
I can't say I've tried that and don't have a good way of testing at the moment, but have you tried looking through the default HomePage_wsp page to see if you can borrow something from the way Oracle creates the links?
yes good idea, I only have 126.96.36.199.900 env so there is no such files but I should be able to find 188.8.131.52.000 install files somewhere
