How to pass a parameter in URL?

[Wicke]

I would like to pass a parameter (e.g. @AssetName=PC001) to my new created report in order to set a filter.
Unfortunately this seems only possible to some Reports like "report.aspx?&det=dynamicGroup&@assetgroupid=12"

Is it somehow possible to pass the parameter?

Did you figure out how to define a Scalar Variable?

Found the solution by myself:
It's only possible like described in this thread: LINK

Then a "Skalarvariable" must be defined like @assetid
