seems odd.
No, never experienced that (not that I count rows)
Just for curiousity, what is your datasource? Maybe there is some issue with that, and it will only allow the 5000 records (seems silly to me if it did)
Regardless, it's not CR.
I guess to troubleshoot, I would just link to a simple table that is large and see what comes back. I would also try querying the same value in SQL and see what you get.
I would also try tracing the database call to see what is being sent to the DB, and lastly, if an application is calling the database, see if the application has a limit and is truncating your data before passing it along to the report.
oh, yeah, since I am not conversant with it, is there any limiter on how you connect to the database...again, I wouldn't think so, but I've been wrong before...a lot...
