Are you looking for Tableau Server Approach or you just want to perform this functionality in Tableau desktop.
Before you can schedule an extract refresh, scheduling must be enabled on the server.
- In the top navigation area of the server web editing environment, select Server > Settings.
- On the General page, under Embedded Credentials, select the following settings:
- Allow embedded credentialsFor some data source types, scheduled refresh tasks are possible only when credentials are embedded.
- Allow scheduled data extract refreshes
But as per my understanding (In context of Tableau Desktop),
In Tableau Desktop, the only apparent method for refreshing a data connection is to right-click the data connection in the Data pane and select Refresh
Thank you fro the response.
One thing that I want to bring to your notice is that my dashboards are connected live tot the database. It is a live connection and not an extract from the database.
As the latest data loads the dashboards refreshes but is there a way to schedule this refresh . I have published the dashboard in the Tableau server.
