Based on the feedback from clients, a "IsLocked" feature was developed to improve the control of the data in the PrimeObjects system. In many cases, user may want to keep a special record safe from unexpected updates or deletes. For example a Financial Model that was created by a Sr. financial advisor for his clients or Jr. financial advisors can be locked from any changes. Although properly applied security settings can also protect a certain record from any changes, IsLocked feature makes this kind of protection easier.
