Customers-Invoices-products advanced relationships?

Hi,

How would you design the relationships between customers, invoices and products where :

  • A customer is member of a customer type.
  • Each customer type can have different prices for different products.

The image represents what I think would be a good beginning.

You need an unstored calculation field cCustomerType in InvoiceDetails, and make the relationship from there to ProductPrices match BOTH ProductID and CustomerType - otherwise you won't be able to lookup the correct price.

Yep, your right. I made up this one quite rapidly. I forgot this field and relationship.
