Hi BJ, Thank for your quick reply.
I understand that in OFBIZ we can use an "Appl" table to implement the n:m relationship technically. What I don't understand is the business level design of these two relations: What's the purpose to associate a product feature category or group to a product category? I haven't find anywhere can use these relationships.
