To connect to Access Financials, you will need a SQL login for the particular dataset being accessed. This can be requested via support by logging a new case online with details of the server and database for the connection. Once this is received, the steps below should guide you through the process:
In Data Engine, go to Connections.
Select Add New (Connection) and click SQL Server.
Enter the Name you wish it to be known as and a Description if required.
The Connect Via field should be set to Direct.
Enter the Server name followed by .cloud.access.com (there is a full stop at the start of that text)
Then the Database name.
Save Changes to confirm.
