An upgradation is done at one of our client site from SAP 2007 PL 15 to SAP 8.8 PL 19.
Also OS changed from Windows Server 2003 to Windows Server 2008.
Before upgradation the reports were created in Crystal report 2008 are not working in the current scenario.
They are giving error "Unknown Query Engine Error" in SAP 8.8 PL 19.
And if i only runs the report file it gives error "Unknown database connector error" in crystal report 2008.
I'm using OLE DB connectivity in the report to the database.
Also the case is that these reports which are not working now,
works on client machines.
They are giving error in their server only
Please provide solution to this.
Thanks & Regards,
