Is it possible somehow to display the tickets associated with the Company or Contact at the Deal card.
I see that it is possible to create a new association Deal-Ticket but I don't want to do like this, because in fact the exact ticket can not relay to the exact deal. Also it's difficult to manage this association in my case. I just want to see if there was a communication with the Company (by means of Tickets) directly at the Deal card without opening Company or Contact card.
there must be a direct link between the ticket and the deal so that the ticket can be displayed in the deal. The only alternative I can think of is that you could create a view based on Company and then display the associated deals and tickets.
In this case, the ticket does not have to be directly linked to the deal. It's not what you specifically wanted - but I don't have a better idea right now... You could add the information in the deal whether a ticket exists. But that's also a bit tricky.
