Including a CR 2008 report in a CR XI application
Are there any issues including a report built in CR 2008 into a CR XI application?
As long as the report isn't using new functionality that is only available in CR2008 it will probably run just fine in CR XI. This isn't supported, but it should work.
Business Objects, SAP has never supported running newer reports (CR2008 is v12) with older runtime files (CR XI is v11.0). If you have any issues with the report the first thing to try is running an original CR XI report that has the same design, formulas, etc. If the CR XI report works, but the CR2008 report does not then you have your answer.
