Siebel Tools >  How to Configure a link

Go to Contacts -> Contacts List -> All Contacts

Find out the view details from Help -> About View

Screen: Contacts Screen
View: Contact List View
Business Object: Contact
Applets: Applet[0]: Contact List Applet; Applet[1]: Contact Form Applet;
Business Components: BusComp[0]: Contact; BusComp[1]: Contact;

In the Last Name column , there is a link. Click on any last name hyperlink.
This will take us to this screen

Screen: Contacts Screen
View: Contact Detail View
Business Object: Contact
Applets: Applet[0]: Contact Form Applet; Applet[1]: Contact Activity List Applet;
Business Components: BusComp[0]: Contact; BusComp[1]: Action;

Open Siebel Tools, go to Applet and search for Contact List Applet
Lock the project. Go to Applet -> Drilldown Object.
Query for Hyperlink Field = Last Name and View = Contact Detail View

Change the View to Contact Monthly Calendar View.
Compile the project.

Restart the web client (it should restart automatically if the autostart option in compile was selected).

In the web client, go to Contact -> Contacts List
Check that when you drill down on the Last Name now, the link changes.
The hyperlink will take us to this page now

Just remember that we changed the hyperlink to another page in the same component (Contact).
If we want to go to another component applet, we will have to find out and edit more fields.
