Getting global objects
To "Get" a global object means that you can retrieve a copy of the object without putting a lock on it or formally checking it out. You can also get an object even if it is locked to another user.
Note: Both getting and checking out an object overwrite any existing copies in the run-time database with the version currently in the master database. This means that you cannot make changes made to a "get" version permanent, as you cannot check in a "get" version, and any changes you have made are overwritten when you check it out.
