ODBC Connection that is used as System DSN is not showing in the SSRS dropdown 'Use user or system data source name' for a data source.
The test connection failed when I try to test the (System DSN) ODBC connection to a Firebird database. This is a possible reason why I am not seeing the System DSN.
Is there a way I can make the System DSN to show up in the SSRS data source ?
