• A change was made starting release 4.2 SP08 Patch 06 to enable navigation without enabling extension Points.

Solution

Update the Webi properties in the web application of SAPBI, by following this procedure :

1. Go to folder SAP BusinessObjects\tomcat\webapps\BOE\WEB-INF\eclipse\plugins\webpath.AnalyticalReporting\web\WEB-INF\classes
2. Edit webiviewer.properties and set ENABLE_EXTENSIONS_SERVICES=yes
3. Go to folder SAP BusinessObjects\tomcat\work\Catalina\localhost
4. Delete folder BOE
5. Restart Tomcat

If it was previously enabled, you can safely disable Extension Point. You can now use Need4Viz navigation components in your Webi reports.
