Using a matchfield relationship but no portal to filter values
does this work?
Given is a table with records from which those shall not be visible in Layout A (table bookings), whose matchfield_visibility=1. So only a part of all records shall be shown. Currently I'm using a script with script-trigger, but this leads to problems and interferneces with other scripts, so I'd like to avoid that. Again, I can not use a portal.
How can I set up a relation that allows filtering without a portal?
It would be great, if the answerer could be quite detailed also about the relation of layout to table.
Thanks a lot in advance, any hints are welcome.
