MDM Change tracker iView not fetching the data?

Hello Experts,

we have MDM Change tracker application deployed and assigned to some role in portal. However, the problem is fields like "Table" etc are blank. I am not able to fetch any data in it. I have activated change tracking for the required table in MDM backend as well.

I was following this blog: /people/balas.gorla/blog/2006/09/08/change-tracking-in-mdm

It is mentioned that some DB setting have to be done and some query to be written. I am confused, I have an iView in portal so do I still need to write the query? Or what is that I am missing?

Please help.
