Stacking/Nesting, Nesting Height

Multiple units of a product can be stacked on top of one another in the y direction on a specific facing on a shelf. When the units are stacked, the total height equals the number of units x the height of a single unit. Nesting is defined as stacked units that fit inside each other so that the total height is less than the number of units x the height of a single unit. The nesting height is the incremental space that the nested units require. The total height of a facing with nested units is determined as follows: total height equals the height of a single unit + the number of nested units x the nesting height. This applies only to shelves.
