In this field you have the option of setting a limitation on the quantity of items sold.
If it is set as None there will be no limitation, but the other option, Sales will limit the number of items you are allowed to sell in a particular
transaction, as set up for the item in Setup - Item - Sale Limits.
This feature is useful when there is some sort of a restriction involved, for example in a Duty Free environment where there usually is a limit on how much alcohol or tobacco
an individual can bring along to a destination country. Also, it is possible to use infocodes in this context,
for example, when selling a packet of tobacco, to prompt the cashier to ask for age or ID if it is
not allowed to sell such items to persons under a particular age limit.
