Is it possible to prepare report that bases on object that contains multi-level-nesting.
As a example I propose real-estate insurance policy that contains some data-fields (number, effective period etc.) and collection of insured buildings. Every building contains also some data-fields (address, description, is it easy-flamable, how many floods have occurred in its area etc.) and it contains list of risks. Every risk is a simple data-object that contains code, name, sum insured value etc.
