I have a Crystal Report that I developed in CR2008. We have switched to Crystal Reports 2011 and upgraded the Crystal Runtime from version 12 to version 13. In Crystal Runtime 12, my report would give me the correct amount on the total line when ran in summary, and then in drill-down. In the Crystal Runtime 13, I get the correct total when the same report is ran in summary, but when I drill-down my total changes and is incorrect. The only thing that has changed is the Crystal Runtime Environment and we are now using Visual Studio 2010. The report functions correctly running it with the VS2010 app and the Crystal Runtime Environment 12. Change the runtime to 13 and that is when I get my issue. Does anyone have any suggestions or know of a fix? Thank you in advance.
