You need to set the database user's login and password before setting the ReportSource

' Set the database login to avoid "Login Failed" errors
            cryReport.SetDatabaseLogon("user", "pass")


I had the same issue, this was the only sure-fire way of making sure it works across development, staging and production servers.

Thanks for the quick reponse.
I have about 8 other reports which are working just fine and i actually have views created in Oracle which server to populate reports.
Now this is the only one which does not work even though it uses the same log in info as other reports do.
This report works just fine in development environment.
Thanks

If it is possible, try recreating the report. Crystal reports sometimes can get messed up and store hard-coded connection information in itself. Otherwise, try the solution recommended by SuperGhosty :)

nauman is correct, there seems to be a bug with crystal reports.

I have been able to remove the connection information completely from the report and then recreate it and my report started working again. However it happened again so I hard-coded it programatically.
