While there are cases where you want users to be able to change their session date which controls the default Posting date on transactions, there are times such as immediately after Go Live, where you might not want new users to have that level of control.
To disable users updating the session date for all users or a group of users, update System date security settings in the Client essentials security privilege.
Users will be able to see the Calendar object but not update their session date.
