Two-way linked view

Two-way linked view

I am in the process of migrating our old ZC applications to ZC5, and in order to clean up old design mistakes we are building the app again from scratch so as to have one "backend" app that contains all our global data, and then various frontend apps that will refer to the backend data.

So far so good - my problem now is however, that when I in a frontend app refer to data in the backend that is again pointing to the front end, I can not create a linked view between two frontend reports within the same app where the backend record is the common denominator.

Is there a smart workaround for this or it is just the way the system is?

A fictive example to explain the problem:
For the company Onion Carriers there is a record in the app Data for Warehouses.
In the frontend app scheduling there is a Schedule report showing which warehouses the Onion Trucks have to drive to.
In the frontend app there is also a report with Details for each Warehouse.

However since the Warehouse name and code comes from the Data app, I cannot create a linked view in Schedule from Details but only to the record in Data.
