The Customer Order Delivery Preparation Aggregate Function allows in the context of a customer order to: <br/>• query catalogues and installed bases to identify what needs to be delivered: Service Specification (CFS Spec) and its configuration, Stock Item, Supplier Product, Work Spec, related to the ordered product,<br/> • prepare a Service Order (CFS Order), Supplier Order, Stock Item Order or Work Order with the necessary information. In the case of a Product associated with an Internal Service (Know-How), this function also allows to: <br/> • check if a corresponding Installed CFS is operational in the Service Installed Base, and so determine the operation at CFS level (creation or modification) <br/> • possibly group in the same Service Order several ordered products, based on the same CFS specification, and/or identified to be delivered at the same time by the Customer Order Delivery Orchestration.<br/>
