User class
Budget information often is confidential and must be secure to ensure financial accuracy. You can define a user class that enables you to determine a list of users who have the authority to add or modify budgets. When you assign a user class to a budget, all users assigned to that user class can access and modify information. Users not defined in the user class can inquire on any budget, but they cannot add or change data.
See Defining budget header information.
As an option, you can lock budgets to prevent them from being changed or deleted. You can also limit who can lock and unlock budgets to secure the locking procedure.
