I have an Excel table, and based on this data, I want to build a report with some aggregated values (sums), each one according to a set of criterias . For each aggregated value in this report, I want to be able to get to the corresponding table rows, change a value in any of these rows, so that the underlying table data changes, and I re-run the report to get an updated view. What is the easiest way to achieve this requirement?
