The 'x' parameter is missing a value in SSRS

Question

Although many times posted on the Internet it didn't give me the answer yet. I have an Internal parameter with a default value as "Get values from a query". The Report runs fine as long as there is output from the query. Otherwise the above error pops up. I have tried all possible solution posted. Nothing helps. If I define the parameter as Visible it works fine as well. Does anyone has a suggestion not posted yet?

Answer 1

Make it so your query always returns something. Without a value for your parameter, the report will not run (thus your error). You can return a value that you know means there were no results and have your report perform any logic desired based on that value.
