To see whether a newer set of data is available for exploration in a project, you can refresh the data source data and metadata.
Click Canvas Settings on the project toolbar and select Refresh Data. This action clears the data cache and reruns queries to retrieve the latest data from the data sources to display on the canvas.
Click Canvas Settings on the project toolbar and select Refresh Metadata and Report.
This action refreshes the data and also any project metadata that has changed since you started working in it. For example, a column is added to the subject area used by the project. You use this menu to bring the new column into the project.
