This script is used to know if quantity should be shown to the user. Usually, not showing quantity happens when a total quantity is shown instead, meaning the line uses cells.
* If this is not a movement (line containing lines or cell), user cannot see quantity for this line which is just a container, but no actual movement.
* If this line has required variation category list, then it means it's a line that will contain cell, so total quantity will be used instead.
* If this line has optional variation category list, and already contain cells, total quantity should also be used.
