How can I extract a km-iView out the portal to redefine it?

Hello folks,

I want to redefine the com.sap.km.cm.navigation-iView to serve generic access to the users home drive by using the <User.UserID>-variable. Therefore I have to extract/download the iView out of the Portal. I wasn't able to find KM-Content in Systemadministration->Support->Portal Runtime->Browse Deployment. What do I have to do?

How can I extract a km-iView out the portal to redefine it?

Regards

Steffen
