I have huge problems with sending parameters between reports in SSRS. Here are a thread I have created.. http://social.msdn.microsoft.com/Forums/en-US/sqlreportingservices/thread/3ecfe927-7b03-4279-92a4-b15e382b8144.
The issue with the YTD-function is also not solved so it´s not clear what I should continue with next week. Should I switch to regular T-SQL? Maybe go back to the already created ERP cube? Guess I decide on monday..
