Want I really want is ... if I'm wanting 3 of Kit A from location A. Does location A for the component onhand quantities (which would requires deviding the raw onhand by the member quantity)

Apologies if this is already answered or I'm misunderstanding. There is member item and memberquantity, that can be used here. https://system.eu2.netsuite.com/help/helpcenter/en_US/srbrowser/Browser2018_1/script/record/item.html
