SSRS Main report error

Hi Nichesl,

The error message “An attempt was made to set a report parameter 'CustomerId' that is not defined in this report” indicates that there is no 'CustomerId' parameter in subreport_1. Did you define that parameter in subreport_1? The "CustomerId" part of the Report Parameter must match the name of the parameter in the report.

Also, note that report parameters are case-sensitive. So please try to open the report to double-check the parameter name.

Hope this helps.

Thanks,

Katherine Xiong
