Subreport could not be shown. If this happens when printing Report Cards, it's possible there are two .dll files which need to be updated in your SQL Reporting Services.
Click Here to get the updated .dll files which need to be expanded out of the .zip file and installed in your SQL Reporting Services:
- Install here if your run SQL 2012: C:\Program Files\Microsoft SQL Server\MSRS11.SQL2012\Reporting Services\ReportServer.
- Install here if you run SQL2008R2: C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer\bin
Your location might vary slightly from the examples, but you definitely want to be within here: Reporting Services\ReportServer. In that location is a bin directory. Copy -- REPLACE -- the two .dll files into that bin directory you find within your ReportServer directory. Best Practice: Perform this replacement in two steps:
1. Delete the two existing .dll files first.
2. Then move the two files we give you into that location.
