Most significant cumulative data will be available from the statistical reports on CCMA or through ODBC connection. RTD will provide /some/ cumulative data on a "moving window" or "interval-to-date" basis. And, of course, you can collate your own statistics from RTD/RSM where appropriate. Have a look at those options to find which best matches your own specific needs.
For detailed assistance, you might like to review the possibility of using paid support for requests where we can engage your problem more directly (because forum support is ad-hoc, as time allows). To avail of the full support (and other benefits) you should upgrade your DevConnect membership through the "Membership Tools".
Good luck with your application.
