Managing product generations

Instead of referencing a specific configuration item when you define an effectivity map, you can reference a separate entity—the generation item. The following figure shows a simplified product structure in which the effectivity statements referenced separate generation items (2005–MY and Generation2), rather than a specific configuration item. These generation items are items that can exist independently of a product structure. Product generations The effectivity map of this structure is as follows: End item/revision Effectivity range Subeffectivity 2005_MY Gen2 2006_MY Gen3 002585–Truck Jan 2007 – Apr 2007 Jan 2007 002997–Truck May-2007 – Onward Gen2, Apr 2007 In this example, the 2005_MY parent end item configures the Gen2 end item when you enter the Engine/A assembly. Similarly, 2006_MY configures Gen3. The final line of the example shows how you can transform multiple parameters (End Item and Date) in a single mapping.
