A method and system for splitting an order in a flexible order transaction system where yield, scrap, and work-in-process (WIP) are calculated for reporting points in the parent order process and certain yield, scrap, and/or work-in-process units are transferred from reporting points in the parent order to mapped reporting points in the child order. The transfer from the parent order to the child order being possible at several mapped reporting points for the single split order action. If the WIP to be transferred at a mapped reporting point exceeds the available WIP, WIP may be taken from preceding or subsequent reporting points.
