Nvigating to a POrtal role from a link in HTML file in KM

Hello All,

I have a requirement to navigate to a role in portal when user clicks a link on a KM document iView (htm) in another role.

Example:

Suppose user has following view in portal

Role1  Role2  Role3 ............................. 1st level tab

|

Workset1 Workset2

|

iView (KM document type HTM file)

So the requirement is if user clicks on a link on the HTML then it should navigate to Role3

Please advise.

Thanks

Shobhan
