For example, you wish to unpack two eaches:
Scenario 1 - Six eaches make a case and 18 eaches are in a Package ID. You cannot unpack the two eaches. In this example, because the unpacked quantity must be a multiple of six or a Full Case.
Scenario 2 - There are a quantity of two eaches in a Package ID. In in this case, you can unpack two eaches because it is less than a Full Case
