Report users can add comments to saved reports using Cognos Viewer. Comments can be added to HTML, PDF and XML reports, but not Excel or CSV reports.
Comments are added to a specific version of a report and are deleted with that report version. The comments are not available in other versions of a report, unless they are manually added by a report user.
Comments are included when a report is viewed online or when a burst report is distributed via the portal, but they are not included in printed or emailed reports.
Before a user can add comments, the report owner must enable comments in saved output versions.
To add comments, a report user must have read permission to the report output. These comments are visible to all other users who have read permission to the report output. However, only the comment owner, or an administrator, can modify or delete comments.
Enabling comments lets a report user add comments to saved HTML, PDF or XML reports.
For information about adding comments, see Add Comments to a Report Version in Cognos Viewer.
