It's simple enough to modify the VI any way you want. The cancelled output is wired to a case statement that sets the error status Boolean to True and generates error code 43. You can remove the write to the error cluster. The other way to do it is to trap error code 43 in your main VI by just doing a comparison and clear it or do whatever other action you might want to take. If you do modify the VI, make sure to save it with a new name and in a new location.
