Beyond the purely ludic and mathematical aspects of sudoku, this code demonstrates how to set up dimensions, cubes, views, cell formating, security at elements and cells levels all through Turbo Integrator in just one process.
Locking cubes is a good way to insure your (meta)data is not tampered with.
Right click on the cube you wish to lock, then select Security->Lock.
This now protects the cube contents from TI process and (un)intentional admins' changes.
However, this makes updating your (meta)data more time consuming, as you need to remove the lock prior to updating the cube.
