We have a crystal report that give this error Error : 599 - Cannot open sql server. This is a report with 13 sub reports. The version of Crystal report is 126.96.36.199. The database is Oracle. It runs fine from Report designer. When run from the Application it gives this error. The application is in Powerbuilder 6.5. The report seems to running fine in production on the users machine. We recently upgraded PowerBuilder 6.5 to 8. This report is not running in both the versions of the application. I have read through the other threads and couldn't find a solution for this. Its hard to say that the problem is machine specific because it works in other machines. Any help is highly appreciated.
