I need certain custom entity fields to calculate and display values based on operations on the data in the system.
For example an a booking system implementation with contacts and custom entity: tickets. There is a one-many relationship between contact and tickets.I would like to create a field that calculates and displays in the contact form:
1) frequent flyers: more than 10 tickets bought.
2) a field that displays yes or no based on whether a first class ticket has ever been purchased. Ticket ref would start with say, FCxxx
If this isn't possible perhaps someone could suggest an alt method for displaying this info?
