I am trying to solve for a relatively simple inventory practice but don't see an obvious solution in Zoho inventory. Hopefully I am missing something basic and there's a way to do this. I am trying to take cases of product and 'break' the case. I want to be able to sell the items by both the individual unit and the case. I have UOM enabled with a unit group that sets the units per case and the individual unit. Is there a way to transfer the case inventory to be individual unit inventory? I'd like to have the two products linked in the system for batch tracking and easy reordering, the root product should be the case. 

I've tried creating a composite item with 1/10 of the case quantity, but the system does not want to let me save this and keeps giving me an error message. 

Any help is appreciated!
