The business need is to set up allocation rules that always allocates cases of product, regardless of the setup on the product record. For example, on the customer tab of the product record the unit is EA (each) If a case of that product is equal to 12 EA's and the customer orders 24, the desired allocation should be for 2 cases, not 24 eaches.

We have tried many different settings on the allocation rules, both globally and at the category level, and the system will not behave in this fashion. If the sales unit on the customer tab of the product record is EA, it allocates 24 eaches. If the sales unit is cases it allocates 2 cases. Is it possible to write a global allocation rule that always allocates cases, regardless of the product setting? If so, what is that configuration?
