Problem: In Remedy, when clicking on a button that is supposed to run a Crystal Report, an error returns with, “. . . Failed to open the connection- ODBC data source – AR System ODBC Data Source [ARERR 1904].”
Cause: A Remedy installation uses a special ODBC data source which is installed just for running Crystal Reports. This is a System data source the Remedy User tool cannot see because a User account is running the Remedy User tool.
Cure: Create an ODBC data source that the Remedy User tool can use.
-Go to Control Panel/Administrative tools/Data Sources (ODBC). Select “User DSN” tab and click “Add.”

-Select “AR System ODBC Driver.” If you don’t see it, it is likely that Crystal Reports and ODBC were not installed with Remedy or will need to be reinstalled.

-Click “Finish.”
-This should open the “Setup” window. Enter “AR System ODBC Data Source” as the “Data Source Name:” All remaining fields should be left blank.
-Click “OK.”
