CAP - Value Help access other fields from screen

[nothafts]

Hello,

At the moment I'm exploring CAP by a small demo project - table reservations in a restaurant. In the data model I have two entities:

So the restaurant manager creates a table reservation by choosing a certain Table. In the UI, the user selects from all the Tables.
If the Table is already reserved, an error message should be displayed.

A requirement for this example would be to filter the content of the value help by removing Tables, which are already reserved at the "Reserved For" date.

Is this somehow feasible? (of course, it would be also nice to display only Tables with an appropriate number of available seats)

Thank you very much.
