I have a report that includes a sub-report. The sub-report is a list of events related to the report.
In standalone designer, when I preview the report, the sub-report's contents relate to the report correctly. I think that's because the parameter value is set.
In production, running from an application (Asp.Net Core 5) the sub-report shows the events for the parameter set in the designer. The main report contains the correct information.
Both report and sub-report use the same database connection and the same parameter name.
This seemed to start a few months ago. Not when the reports were first created/deployed.
Any idea what's happening?
Thanks
