Hi @Dileep Raju
There are multiple places from where these fields are made read only when interaction is closed.
I do not know the business reason why you want to do this but here is the answer for your question:
1. State field made read only from client script named : Make state read only after record closed and ACLs for write operation 'interaction.state'
2. Transcript is set to ready only for everyone and thats from dictionary of the 'transcript' field
3. Assinged to and Opened from from UI policy 'Set assigned_to, number, opened_for to read only when state changes to closed/wrap_up'
Consider modifying above as per need (as per agent's role) or adjusting the script and you will see said field available for agents.
If my answer has helped with your question, please mark my answer as accepted solution and give a thumb up.
