This article describes the following topics related to the Lock/Unlock feature in Logica:

The Lock/Unlock feature allows for any editors in a model to lock a specific node's values across all scenarios and time steps. This protects the values so no one can accidentally change the values, which adds an extra layer of protection. The lock/unlock feature can be found at the top right of the right-side panel when a node is selected. The icon, as seen below, is a lock and the locked status of a variable can be seen next to it. In this case, it is "LOCKED." Additionally, any node that is locked can be unlocked at any point. Lastly, by default, the lock is unlocked for every node when it is created. Nodes can also be locked/unlocked from the Advanced Node Settings window.

The Lock/Unlock feature is used to maintain control over model values and which ones can be altered. Locking a variable prevents its values from being changed by anyone who protects the data within it. This can be used in any situation that requires the needed protection providing users a little more peace of mind. Specifically, when a user tries to change the values they will see the following message at the bottom-right of the RSP letting them know why changes cannot be made.
