I was doing a testing for one of my requirement and i enabled the checkbox for 'Use Subscription of the Legal Entity' in party tax profiles by entering the details as party type as : Operating Unit owning tax content and given my party name. Now i want to disable(un-tick) the checkbox of 'Use Subscription of the Legal Entity'. I see the update button is in read only . so not able to disable it. Please help how to do this in front end . Is there any way to work with profile options to enable?
