My business is looking to restructure the WBS we are using in SAP PS. Currently we are setting WBS by deliverable and want to move to a WBS by Commodity such as Valves, Instruments, etc. Our struggle is that when we set a WBS for a commodity it allows budgeting, ETC, and actuals by commodity but we need to consume those commodities into a production order. As we are using Project stock materials when we add demand to a production order for example of a material master that has already been linked to a commodity the system ignores the project stock and generates duplicate demand.
What we are looking to do is basically have the material financially settle to one WBS but the material to be consumed on another without duplicating the demand.
Any ideas out there on how this can be accomplished?
