the Set the e-mail options dialog box.
 This restriction applies
to all IBM® Cognos® Business Intelligence users. 
  
Procedure
- Stop the IBM Cognos service.
 
- Open the c10_location/templates/ps/portal/system.xml
file in an XML or text editor.  
For pages and dashboards,
open the c10_location/templates/ps/system.xml file. 
  
- 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/>
 For
more information about modifying the system.xml file, see Hide User Interface Elements Using the System.xml File.
