You can remove a result set from a project. Removing does not delete the selected run reports and their result sets from the system; it removes them only from the current project.
In the Data tab, click Projects to see the list of projects.
To view the list of result sets in the project, in the Name column of the Projects table, click the project name.
Select the checkboxes in the row of the result sets that you want to remove from the project, then click Process Selected > Remove from Project.
