I’m currently trying to learn DAML by developing such a card activity management system. I have a template, let’s say Card which consists of cardType, cardStatus, ExpiredDate, and PINOffet. However, I need to restrict the PINOfset field, even signatory is not allowed to see it.
How to do that in DAML? is there any mechanism to restrict the authority in field’s level?
Your feedback very useful for me.
