I have encountered a problem with report parameters in SQL Server 2012 SP1 after applying Cumulative Update 4 (Build 11.0.3368). Some of the report parameters are grayed out and will not allow data input. The reports function correctly in production (Build 11.0.3350). I have removed the update from my development instance and the reports functions correctly again. I have attached images of my development and production report screens showing the issue.
Thanks,
