Thanks guys for your quick response.
Frankly I don't know what is wrong with our Group model.
The Local Model extracts does have good size of ~130MB(around 170K objects) extracted from this Group model.
But due to some reason which I don't know these extracts don't show the Action diagram or Triples for the objects.
We have different Variant and levels for some the Action diagram/triples displays for some it doesn't.
After several failed attempts to fix the Group Model(changing configuration etc..),
Then we started thinking of the possibility of making one of our Older Local Model as Group Model.
As we have very limited knowledge in Admin part of plex am not getting sure of the extract process/feasibility of this.
Thanks
Kumar
