The "Type" field is configured with a drill down object. And i checked the responsibilities associated with the view to which i have to drill down. I possess all the responsibilities associated with the view. I also checked if the View was active and found it to be active in Tools.
Still i dont have the hyperlink in the values of that column in my client.
The "Type" filed is part of "Account Activity List Applet". And the view that i have to drill down is "Activity Detail Summary View".
