Hi Joh04924 and others pursuing the L2 course, I would recommend looking at the system modules already available to you that align the parents for each hierarchy level. Readily available are the Product Details and SKU Details modules which list the parents in their modules. Create a new (intermediary - they make it sound more scary than it is) module that takes the growth rate line item by Product Family and write the lookup for SYS04 Product Details.Product Family. Then in the Demand Forecast module, do the same but for SYS08 SKU Details.Product The second one would look like so: 'DEM02 Volume Growth Rates by Product'.Growth %[LOOKUP: 'SYS08 SKU Details'.Product] Cheers, Aaron
