If you are dealing with your server being bogged down because users are emailing reports and sending them as attachments, then you may want to investigate disabling this option. You would be required to modify the system.xml file [ BACKUP BEFORE CHANGING!!!]. You can hide the “Include Report” check box as an option for the end user to select. This change will apply to all users.
The steps to perform this are:
1. Stop the Cognos 8 service from within Cognos Configuration
2. Back up the System.xml file located in …C8 install path/templates/ps/portal/. Open the system.xml file in an XML or text editor.
3. Add the following XML code to the <system> element:
<param name="ui_hide">
<CC_RUN_OPTIONS_email_attachment/>
</param>
If you hide other user interface elements by modifying the system.xml file, the <param name="ui_hide"> element already exists. In this case, add the following to the element:
<CC_RUN_OPTIONS_email_attachment/>
4. Save the System.xml file.
5. Restart the Cognos 8 service from within Cognos Configuration.
