Filtering Entry Points
You can filter entry points so that only certain entry points are displayed in a given desktop. This is accomplished by specifying a Filter ID for roles, worksets, or folders that have been defined as entry points, and then adding the relevant Filter ID values to the desktop. At runtime, the desktop in use only displays the entry points with filter IDs that match the filter IDs specified in the desktop.

§ At runtime, portal users need to log off before switching to a filtered desktop. Switching to a different URL alias in the existing session is not supported. More information: SAP note 1162644.
1. Activate filtering by configuring the navigation_events_helper service:
a. Navigate to System Administration ® System Configuration ® Service Configuration.
b. In the Portal Catalog, open Applications ®com.sap.portal.navigation.helperservice ® Services.
c. In the context menu of the navigation_events_helper service, choose Configure.
d. In the FilterbyDesktopView property, change the value to one of the following:
■ 0 – Filtering is disabled.
■ 1 – Filtering is enabled. At runtime, if no match can be found between filter IDs defined in the role, workset, or folder, and filter IDs defined in the desktop, all content is displayed.
■ 2 – Filtering is enabled. If no roles match the defined filter, only roles without a defined filter are displayed. If all the roles have filters, the header area displays an empty top-level navigation.
e. Click Save, and restart the service.
2. Navigate to Content Administration ® Portal Content.
3. In the Portal Catalog, locate the role, workset, or folder to which you want to add a Filter ID value and from the context menu, choose Open ® Object.
4. In the object’s Property Editor, in the Navigation property category, find the Filter ID property and enter any value.

You can add more than one Filter ID to an object so that the entry point can be displayed in more than one desktop. Separate entries with a semicolon (;).
Leave the field empty to display all entry points.
5. Add Filter ID values to any other entry points that you want filtered.
6. Navigate to System Administration ® Portal Display ® Desktops & Display Rules.
7. In the Portal Catalog, locate the desktop for which you want to filter the entry points and from the context menu, choose Open ® Object.
8. In the Filter ID field, specify the filter ID(s) that you defined for the entry points that you want to appear in top-level navigation. Leave the field empty to display all entry points.

At runtime, if no match can be found between filter IDs defined in the role, workset, or folder, and filter IDs defined in the desktop, all content is displayed.
