Creating iViews in Portal via Launchpad -> error

Hello,

Iam currently trying to create a iView inside the portal via the content of the Launchpad (LPD_CST)

The example is quiet simple, i just want to create a URL Applikation and displaying it on the portal page.

When i start the "Preview" of the iView, the content is displayed with the created link (URL-Application)

So i thought if i just click on the Link (URL Test) , a new windows may appear with the correct URL, which i inserted in the Launchpad on NetWeaver.

But there is just another pop-up Window displaying an error "Page not found" in a separate window with blank content.

The iView is created via iView from remote Source, Apb_Launchpad, + roles and instances from Launchpad Settings.

Any Ideas?

Thanks in Advance
