I'm trying to figure out how (if it is even possible) to allow a user to add a 'flag' to say when they have actioned a row in an SSRS report. This would need to carry back into the underlying tables.
Any help is appreciated; whether it is telling me this is impossible or giving me an idea of where to start.
No, this is not possible in Reporting Services. You will need to look into building your own solution in .NET
