A simulation can be locked to prevent any changes to its data. This includes all data related to the simulation such as parts, part resource requirements, part forecasts, resources, resource capacity and sales contracts. Sales Contract Statuses are not related to a simulation and are therefore not affected.
When users attempt to save changed data for a locked simulation, an error is raised that the simulation is locked and cannot be updated.
The lock status is also checked when performing Copy operations. It is not possible to perform these when the simulation is locked.
The ability to lock and unlock a simulation can be assigned to specific users. The users capable of changing the simulation lock setting can be controlled using a separate permission setting.
