In duplicate task all fields should be read-only except worknotes when it is in closed state

[Abbas_5]

Hello Everyone,
In duplicate task, all fields should be read-only except work notes when it is in closed state in both list view and form view.
In form view I tried with UI policy it is working but in list view it is not working
I tried with write acl Name is Reconciliation duplicate task and the field is None.
condition state is closed state.

list_edit acl will it work?

Is there any other way, could you please assist me on, how to fix this issue?

Thanks & Regards,
Abbas

Hello you need to create write ACL tablename.*  with condition and script:

answer = false;

and have another field level write acl for worknotes field which will allow to edit

If you move your UI Policy into a Data Policy, it will cover both Form & List views.
