SSRS - Suddenly the report only shows “No Data Available”

Question

To get the data for my report I use a stored procedure.

One of the SP parameters is called "date" and was unused until yesterday, when I added a report parameter called "date" which passes a date value to the SP.

But after that the chart in my report only showed the message "No data available." So I set the report parameter "date" back to NULL so the SP ignores the "date" parameter (like it was before). But the chart still shows "No data available".

When I execute the SP (with and without "date" parameter) the SP delievers data.

I have no idea, why the report doesn't show the data...

It sounds like the SSRS interface is not passing the DATE value in the format your SP is expecting. I would use SQL Profiler to find the exact parameter format which SSRS is passing. From there, you can edit the SP or report as needed.
