IS there a way to freeze a document for particular user after every particular date.
For e.g) the sales employee has access to sales invoices , he can create as well as cancel and amend in case of any errors,
But at the end of each month the sales manager will review and audit all the invoices created by the employee.
and after that those invoices should be frozen to the employee to make any further changes.
How to handle the user permission in that case ?
