Hey @kuttti ,

Please follow below steps:

You will need to create 3 list edit ACLs for this requirement:

1. Create an ACL for the table using "SCTASKs.none" with no restriction
2. Create an ACL for all fields in the table using "SCTASKs .*" with Advanced checkbox as true and in the script write -  answer = false;
3. Create an allow ACL for the field you want to be editable using "SCTASKs.Assigned to"
   
   

I am using sctask table as a basis, you can do the same for your requirement.

Feel free to mark correct, If I answered your query.

Will be helpful for future visitors looking for similar questions 🙂
