It's possible to launch Crystal Analysis 9 applications from Crystal Reports and vice versa using URLs containing parameters, if that's what you need.
To launch a Crystal Report from Crystal Analysis, create an URL action on the data source - you can pass parameters etc to set up the report in the URL.
To launch a Crystal Analysis 9 application from a Crystal Report you can simply do the same with hyperlinks in the report. Again, parameters in the URL can be used to initialize the application with relevant context.
