I am stumped on what is probably a simple glitch.
I have an SSRS 2005 server report based on a stored procedure dataset, which accepts a single parameter. The parameter value originates from a session variable when the user opens the aspx page containing the reportviewer control (Visual Web Developer 2005). I've configured this parameter as a hidden parameter in the RDL design. In this configuration it functions as intended in both the development environment and when deployed.
Next, I tried to add user prompts to implement report server filtering (in addition to the database filtering in the source SPROC). I added the parameters, set up the data sources for the prompt values, set up the filter expressions, did everything that I can find to implement this process.
When I preview the report in the development environment, it works as intended.
When I deploy it and attempt to run it from my http://localhost environment, though, it fails. There's no error message or anything...I don't even get the "Report Running" icon with no rows returned...what I get is prompts which function correctly (showing the right values and letting me select one), but when I click "Run Report" I just get an immediate screen refresh with the prompts reset to the default "<Select a value>" setting. And no report.
I've obviously missed some setting somewhere, for it to work in dev but not when deployed. Any suggestions will be GREATLY appreciated.
