I am seeing some very funny behavior in SSRS 2012 that we are not replicating in 2008.
Long story short
Parent report - Report_Parent
Child report - Report_Child
To get from parent to child, you click a field in a tablix and the year from the parent report is passed to the child report and the child report loads fine.
From child report, I need to switch year values from a dropdown parameter. Values do not change. Values stay stuck to what was received from parent.
Anyone seen this?
