Authoring Reports
Reports can be authored and displayed in the Reports table using the following tools:
For all reports, regardless of how they are authored, the Ready For Use checkbox must be selected before the report is visible to all users in the Reports table. Until then, the report is visible only to users with modify permission to the report (by default, site administrators).
To select the Ready For Use checkbox, edit the report.
Clicking the refresh report list icon 
on the Reports table causes any reports that are defined, but not currently displayed in the Reports table to be added and displayed once the table refreshes. This action updates the Reports table in all contexts for which you have create permissions; if you are a site administrator, every Reports table is updated.
