Crystal Reports 2020 connection issues

[Rene18]

My agency purchased a new upgrade license for the new SAP Crystal Reports 2020, and it was working perfectly fine up until a few weeks ago when I tried to modify a crystal report. I am currently running Windows 11 Enterprise with SAP Crystal Reports 2020 Support Pack 4 Version: 14.3.4.4773. I'm attempting to connect to an Oracle Database with Oracle Database 19c (19.3) for Microsoft Windows x64 (64-bit). The issue I keep running into is the error below:

When connecting to the database in crystal reports I use the OLE DB (ADO) connection -> then click on OLE DB Provider for Microsoft Directory Services -> enter the Data Source, User ID, and Password.

Do you have any recommendation that I can try and fix the connection issue that I am running into? Any assistance would be appreciated.

Did you try looking up the Database Vendor Code? This looks more like a problem with your database to me. Looking up the vendor code or sending it to you DBA should be helpful.

As John suggested it could be your DB Client used, I've never used the MS Oracle Client, it has issue with more than one Table. Always use CR's Native Oracle connection or use Oracles Client.

The real question is What did you change in the report that caused this error?
