About Entities and Reservation

Several users can work at the same time with a Control Builder project. To avoid that different users edit the same object properties at the same time, you have to reserve the relevant object, for example a project or an application, before you can modify its properties. This ensures that only one user can modify an object at a time. When ready, you release the reservation. Now, it is possible for another user to reserve and modify the object.
