Passing Parameters from the Main report to the Sub Report
I've seen where you can Change Links and select the parameter from the sub report to link to the main report. That works correctly but I want to do something a bit different and I can't figure out how. My report is a blank Main Report that consists of about 10 subreports. It's a year to date report. My only parameter will be period and the selection formula should be Period <= @Period. If I link parameter to parameter it becomes Period = @Period. How can I get the sub reports to process this correctly? I don't want the user to have to enter the same period 10 times.
