SQL Server Report Services Premisson

I am currently looking into developing and designing the Report service system for wo开发者_如何学Crk. My user does not seem to have access to Report Builder etc. I have given access to the below roles, but all I can seem to do is view report, create new folders and upload.

Browser Content Manager My Reports Publisher Report Builder

Does anyone know what I need to do to resolve this?

Thanks

Have you tried following the instructions on MSDN?

(These are the instructions for SQL 2008- I think the process for SQL 2005 is similar but may differ slightly)
