I need to modify an existing report where one of many multi-value parameters will be hidden. It is used extensively in the code (stored procedures and functions) and I need the report to use all values which storage procedure for this parameter returns. I understand that I can change all many components comprising report since I need to simply abandon that parameter. My goal is to avoid making all these changes and instead have Reporting Services put all values AS IF USER SELECTED THEM ALL. If it is possible, how to request such behavior?
