I am trying to create a calculator that will calculate monthly price of a product for 12 months plus a 1 time price for a product in the first month. Example if I get a product for $10/month for 12 months and it will cost $50 to install I want a line graph to show $60 in month 1 and then $10 the remaining 11 months. How do I structure a table to do this along with being able to filter between differnt products??
On high level for your model you want to three dimension tables (Customer, Product and Date) and one fact (transactions ) table.
Let me know if this is something you are looking for and we can continue with formulas.
