Is there a way to lock the use of VizAlerts down to the data source level? For example, a desktop user may have access to a Transportation data source and a General Ledger data source. We want him to be able to use VizAlerts to send emails containing the Transportation data, but we would not want him to be able to use VizAlerts for the General Ledger data source. We could use the project security, but sometimes we have more than one data source in a project, where we need to limit a user's VizAlerts capabilities. If it's possible, could you share the necessary custom SQL?
