Wang Cheng commented on KYLIN-2904:
-----------------------------------
There already a similar check in ModelService, i.e, checkIfBreakExistingCubes.
It is allowed to add new dims and measures and throws exceptions if deleting
dims and measures already used in some cubes.
> Add compatibility check for model to allow editing model even it's referred
> by some cubes
