Visual Studios
Parameter validation failed in SSRS
Parameter validation failed. It is not possible to provide valid values for all parameters. (rsParameterError)
I saw this error the other day and it took me a minute to recall how I’ve fixed this in the past.
If you are unfamiliar with SSRS and Visual Studios, it can be a little “unfriendly” with some features. Specifically in this case, taking a parameter that used to be hidden and making it a visual integral part of the report. In my particular circumstance, this report is not testable in visual studio and has to be uploaded to a server in order to validate.
