My point was that batch operations are not simple. When they involve UUID’s, 95% of users have already been left behind. So the Guides do not even mention them, because for the vast majority of Manager users, it would just add to their confusion. For the 5% who understand them, the solution is typically obvious.
Understanding batch operations has nothing to do with accounting knowledge. It requires some expertise in relational databases. The Guides are not intended to convey that type of skill. The developer’s goal is to make the program fully functional for people without software expertise, while still providing hooks for experts to use. You may have noticed, for example, that the batch operation buttons are dimmed, indicating they are not primary controls. The Guides are aimed at people with little expertise. They are not meant as detailed software documentation.
