By default, only you can see reports that you create. If you wish to allow others to view your crosstab report, click on the Sharing tab.
Find the name of the user(s) in your organization to whom you wish to grant permission to view the report. Read Only access will permit the user to view the report. Edit access will permit the user to view, edit, and even delete the report. At the bottom of the list of users is a checkbox that controls whether those gaining access to the report are notified. If you want to grant everyone in your organization access, choose Everyone.
Once you've made all the desired changes, use the blue Save button at the bottom left of the page.
Users who have read-only access cannot see the Settings or Sharing sections of the crosstab.
