When I try running the report with a dynamic parameter prompt, I encounter an error 'UNKNOWN DATABASE CONNECTOR - Prompting Failed with the following error message Error Code: 0x80004005. When I run the report without the dynamic parameter prompt, the report runs fine. I am using Crystal Xl 11.5.11.1470 ORACLE 11g. Could you give me some clues on how to troubleshoot this problem or what would cause this problem?
