Zoom from Reference to a session and filter data there

I want an option in a session i.e., whinp1500m000.
Where I highlight a Record for Contract Deliverables for an example, and zoom to session tppdm7100m200 and filter only that contract which was highlighted in whinp1500m000

Zoom is working but not filter considering we don't have source code and extension functionality not available.

Thought about a new intermediate session which will be called by whinp1500m000 and this new session will call tppdm7100m200 using something like this...
query.extend.where.in.zoom


Any good suggesion will be help full.

Thanks

Jay

Well you could look and ~Vamsi source extender. We used qkey to do stuff like this. Sounds like you have LN so wait for someone that knows it.
