I have a report which is working fine on SQL server 2005 reporting service. Recently I moved it to SQL Server 2008 Reporting service but it returns [BC30494] error, saying "Native Compiler returns error: Line is too long". I am using Visual Studio 2008 BI, just bring rdl of 2005 into a new project. Does anybody know about this? Does 2008 implement some limitations on rdl size? I searched about this issue and changed by short textbox name and no helps. There are some expressions inside the report but I couldn't locate which expression caused this error. wondering why 2005 version works. Thanks in advanced.
