Can Primary UOM in Org be of another class than UOM Master

Hi

Most of my finished products are sold as Pcs from one Org (say Org A) and as Cartons in the other Org (Org .

There is no standard conversion between the 2 UOM as every finished product has its own relationship between Pcs and Carton. Thus I have defined these 2 UOM in 2 different classes as they logically do not fit into one class.

Obviously, I have done the conversion betwee Carton and Pcs as InterClass

My requirement: Make the primary UOM of Org A as Pcs and Primary UOM of Org B as Carton

To get my requirements fulfilled, I thought I would define my items using the Pcs UOM as the primary in the master, then keep this primary UOM in Org A but change this primary UOM in Org B to be Carton.
