Does anybody know if I can set a sum of the available inventory of several locations as a criteria of a search result? For instance, if I only want to return items that have 0 inventory in Location A, B and C. I’m assuming this would have to be some kind of formula?

inventorylocation anyof A,B,C

AND

locationonhand lessthanorequalto 0

, if you group them with parens that should get that specific criteria
