When putting away pallets of fright into multiple depth bays what level of racking should be stocked first second and last?

When stocking multiple depth bays with pallets, the first level of racking should be stocked last to allow for easier access to the pallets behind. The second level should be stocked first, as it is more accessible and can facilitate better organization. The middle levels, if any, can be stocked in between, depending on the overall layout and accessibility of the bays. This approach maximizes efficiency and minimizes disruption when accessing stored pallets.
